Video: Recording bouncy bugs with a Phantom camera at 73,000 fps to see how they move
The correct maneuver to perform when you see someone in public you don’t want to talk to.

Springtails are small organisms that move so quickly that the human eye can’t perceive their motion. They’re very common and easy to find but challenging to observe and even harder to understand. Cameras, at least typical ones, are unable to keep up with the small, speedy hexapods. Dr. Adrian Smith, head of the Evolutionary Biology and Behavior Research Lab at the North Carolina Museum of Natural Sciences and North Carolina State University, recorded springtails at 73,000 frames per second to better understand springtail locomotion, which has previously been shrouded in mystery.

Before digging into how Dr. Smith captured the video, it’s worth discussing springtails as their nature. Springtails are hexapods, meaning they have six legs, but they’re not insects. Springtails are wingless arthropods with internal mouthparts. The organism is in the collembola order, one of three in the class ‘entognatha.’ It’s not clear how closely related springtails are to the other two species in the same order, the Dirplura and Protura. Despite DNA sequencing, there remains some debate on the evolutionary history of springtails and how related the species’ history is to other arthropods.

To keep things simple, Dr. Smith refers to springtails as ‘bugs.’ That said, there’s not much that’s simple about understanding springtails. Limited research of the organism has turned up little concerning understanding how springtails get around. The organism is so small that it’s hard to see and so incredibly fast that it’s impossible to observe without the aid of very high-speed cameras.

Last year, Dr. Smith attempted to learn more about springtails by recording them at 6,000 frames per second. Even this high speed was too slow to deliver a full picture of the bugs in motion. He upped the frame rate to 10,000 fps, but even this wasn’t quite enough.

Using a newer Phantom camera, the VEO1310s, Dr. Smith recorded springtails at 73,000 fps. At this speed, the camera records black and white video that is 240 pixels high, but it’s enough to see the organism in a way nobody else ever has.

Smith says ‘I don’t think it’s hyperbole to say no one has seen a springtail like this before […] I feel like it’s not exactly right to say I’m filming these animals in slow motion. I’m not using the camera to exaggerate or prolong what they’re doing: I’m just trying to see it. I’m trying to meet these animals at the timescale at which they’re behaving, and that turns out to be really, really hard.’ As Dr. Smith says in the video below, ‘Pretty much any recording that captures a springtail jump in detail is capturing something new.’

As you can see in the video, springtails propel themselves forward from the surface of the water and perform ‘astonishingly fast’ backflips. In one example, a springtail rotates at a speed approaching 300 backflips per second.

This composite image shows a springtail jumping forward at about a 45° angle on the surface of water. Image courtesy of Dr. Adrian Smith.

The semi-aquatic bug can walk on water and propel themselves forward at roughly a 45° angle using a water-resistant appendage tucked underneath their bodies called the furcula. The tail doesn’t break the surface tension, allowing springtails to use the indentation in the water as a sort of springboard. Springtails have hydrophilic appendages, meaning that their claws stick to the water, which provides traction. On dry land, however, their movement is less regular. Nonetheless, even at 10,000 fps, it’s impossible to get the full picture of the bug.

At 73,000 fps, Dr. Smith captured video of a springtail stuck on its back. What was unfortunate for the creature resulted in what Dr. Smith refers to as possibly the luckiest thing he’s caught on camera. The incident sheds new light on the furcula’s role in the springtail’s locomotion, and you can check it out near the end of the video above.

Springtails may be abundant, but there has been little research done to better understand them. A big reason for the lack of research is likely how difficult the organism is to observe.

We had the chance to speak with Dr. Smith and ask him a bit more about his research and how he captures his amazing videos. He uses a Venus Optics Laowa 60mm f/2.8 Ultra-Macro lens to capture most of his slow-motion video. He also sometimes pairs the lens with extension tubes for even closer shots.

Dr. Smith has multiple macro lenses, but his go-to lens is the Laowa 60mm f/2.8 Ultra-Macro

He tells us that of all the gear he uses, the most important is lighting. The shots in the video above are shot against an illuminated background, which is an LED shot through diffusion material. For the front lighting, an ultra-powerful LED array specially built for high-speed video is required. In this case, Dr. Smith uses lights from Visual Instrumentation Corporation.

There’s a lot of preparation and post-production work that goes into producing his videos. Smith locks down the camera, lights and set, and records as much as possible. The footage is then composited in post. During post-production, he also spends a lot of time removing noise grain from the high-speed footage. He adds, ‘And of course, bug wrangling. Endless hours of bug wrangling. These springtails are so tiny and fragile that the best thing to use is a small fine paintbrush to move them around onto the filming set.’ The set itself is a clear plastic party cup filled to the brim with water.

Tamron announces 28-75mm F2.8 Di III VXD G2 for Nikon Z mount


Image: Tamron

Tamron has announced it will release its popular 28-75mm F2.8 Di III VXD G2 fast standard zoom for Nikon’s Z-mount.

Nikon already sells a 28-75mm F2.8 with an optical formula and calculated MTF charts that are a match for Tamron’s original, stepper-motor driven 28-75mm F2.8 Di III RXD. The newer, linear-motor-driven G2 model features improved optical performance.


Buy now:


The G2 uses a more complex 17 element / 15 group design and has a fractionally shorter minimum focus distance (18cm/7.1″ vs 19cm/7.5″) to deliver very slightly increased maximum magnification. The G2 is also a fraction lighter than the Nikon-branded 28-75mm, weighing 550g (19.4oz), rather than 565g (19.9oz). On the E-mount versions, Tamron claimed the VXD linear motor design was twice as fast as the RXD version.

The focal length range makes the 28-75mm a wide to short-telephoto lens for Nikon’s full-frame Z-mount cameras but could, in principle, be used as a 42-113mm equivalent on DX APS-C bodies, if you wished.

The announcement adds a more affordable option for Nikon’s Z-mount users, but the hope has to be that, letting Tamron compete against its own-brand lenses, might also indicate some relaxation of Nikon’s restrictions around the mount. As the footnotes make clear, this lens is “developed, manufactured and sold under the license agreement with Nikon Corporation.”

The Tamron 28-75mm F2.8 Di III VXD will be available from April 18th at an MSRP of $999. This is $100 more than the E-mount version and a match for the current price of the Nikkor Z 28-75mm F2.8. It’s $200 below Nikon’s launch price for the Nikkor version.

TAMRON announces the launch of fast-aperture standard zoom lens for “Nikon Z mount system”

28-75mm F/2.8 Di III VXD G2 (Model A063) for Nikon Z mount

March 27, 2024, 11pm ET / 8PM PT, Commack, NY – Tamron announces the launch of the 28-75mm F/2.8 Di III VXD G2 (Model A063), a fast-aperture standard zoom lens, for Nikon Z mount full-frame mirrorless cameras1. The lens will be available April 18, 2024, at $999 USD / $1399 CAD.

The 28-75mm F2.8 G2 is compact and easy to use yet has excellent optical performance and is compatible with the latest digital cameras with increasingly high pixel resolution. The AF drive uses a linear motor focus mechanism VXD (Voice-coil eXtreme-torque Drive) that is fast, highly accurate and quiet. The lens also excels at close-up shooting, achieving an MOD (Minimum Object Distance) of 7.1” (0.18m) at the wide end and a maximum magnification ratio of 1:2.7. Additionally, the lens design takes operability into consideration by including a coating with excellent scratch resistance on the barrel of the lens and a rubber focusing ring for a comfortable, secure grip among other features.

TAMRON pioneered the category of compact fast-aperture standard zoom lenses for mirrorless models. Now the 28-75mm F2.8 G2 will be available for Nikon Z mount as the ideal everyday lens for Nikon full-frame mirrorless camera users.

Product highlights

1. Best image quality in the standard zoom lens class

The new zoom leverages the latest design expertise and comprises an optical construction with 17 elements in 15 groups. Two optimally arranged LD (Low Dispersion) and GM (Glass Molded Aspherical) lens elements control optical aberrations to the highest degree. The lens provides high-resolution performance from edge-to-edge and corner-to-corner over the entire zoom range, even at wide open aperture. In addition, the soft, beautiful, round bokeh that can be achieved with a fast-aperture lens adds a distinctive dimension, especially to portraits. The overall compact size and high performance can be used advantageously with top-class, ultra-high-resolution mirrorless cameras.

2. Fast, quiet VXD linear motor for high-speed and high precision autofocus

The AF drive system employs TAMRON’s VXD linear motor focus mechanism. The high-speed, high-precision AF is exceedingly responsive and provides dependable and accurate focusing performance from MOD to infinity, despite the fast F2.8 aperture. The lens delivers excellent focus tracking of moving objects, so you are always ready for fast action. Additionally, the focus motor is quiet, so it’s ideal for shooting both still images and video in situations that demand low noise.

3. Lightweight and compact

The 28-75mm F2.8 G2 is a fast-aperture standard zoom lens with a remarkably compact and lightweight design, just 4.7” (119.8mm) long. The maximum diameter is 75.8mm and it weighs only 19.4 oz. (550g). Filter size is 67mm. With a size that’s easy to carry and a light weight that’s well-suited for handheld shooting for extended periods, the 28-75mm F2.8 G2 will surely become your favorite zoom for travel, street shooting, everyday carry, and spontaneous photo opportunities.

The 28-75mm F2.8 G2 features an MOD of 7.1” (0.18m) at the wide end. The working distance shrinks to around 1.7” (4.4cm) when used at MOD. Because the maximum magnification ratio is 1:2.7, you can get close to your subject for wide macro photography, enabling powerful visual impact with the subject positioned large in the frame while keeping a wide view of the background.

5. TAMRON Lens Utility™ expands the possibilities of still photography and video shooting

The 28-75mm F2.8 G2 is compatible with the dedicated TAMRON Lens Utility software developed in-house by TAMRON that empowers users to easily update the lens to the latest firmware without going through the camera2 and includes functions to support focusing operations and other actions when shooting still images or video. By utilizing a wide range of functions3, users can expand the breadth of expression in still images and video. For example, A-B Focus allows users to limit focusing to two pre-selected focus points, shifting focus from one subject to the other with just a click of the Focus Set Button. Users can also choose between Linear and Non-Linear, which affects how the focus shifts during manual focusing.

6. Enhanced overall lens design for user-friendly operation

Every individual part of the lens has been carefully scrutinized, right down to the fine details, resulting in an enhanced design that optimizes both operability and ergonomics. The surface of the lens exterior is glossy black. Improved abrasion resistance makes the lens barrel harder to scratch and resists fingerprints. Additionally, the grip performance has been improved. The smoothly curved, elegant surface of the brand ring creates a dignified appearance with a design that signifies functional beauty and high quality.

Sony announces major firmware upgrades for a1, a9 III, a7S III and a7 IV


Photo: Dan Bracaglia

Sony has announced major firmware updates for four of its current full-frame range, bringing many features and behaviors up to its latest standards and adding C2PA authenticity verification capabilities.

Sony a1 f/w v2.00

Firmware v2.00 for the Sony a1 is perhaps the most extensive, adding features that have appeared in other models in the three-and-a-bit years since it was launched, such as the lens breathing compensation function. It also adds a handful of new features and modifications of behavior, including an option to ensure the EVF remains on, regardless of the LCD position, and relay playback of images across multiple media. Among the extensive list of additions an updates are features such as Timecode Sync, previously only available in Sony’s Cinema Line cameras.

A series of FTP options, including SFTP support are also added.

The firmware doesn’t activate the C2PA function – which not only authenticates the camera and date/time but also that the photo is of a 3D subject, not a photo of a photo – but instead adds the capability to the camera. Once installed, users need to activate a separate license via the Creators’ App to use the function.

Sony a7S III f/w v3.00

Firmware v3.00 brings many of the updates seen in the a1, including Timecode Sync, breathing compensation and relay playback. It also adds the ability to close the mechanical shutter when the camera is turned off, to mitigate dust ingress, and the ability to transfer Raw files to smartphones.

In addition to the C2PA capability, firmware v3.00 includes the ability to add DCI 4K 24p shooting. Again a license needs to be downloaded to a camera running the new firmware to actually activate the function.

Sony a7 IV f/w v3.00

As one of the most recently updated cameras on this list, the a7 IV gains fewer features than the other cameras here. But in addition to C2PA capability, it adds network streaming, direct cloud upload support and an expansion of the features accessible via software development kit (SDK).

Sony a9 III f/w v2.00 [Expected April 9th]

As the newest of the cameras here, the a9 III receives fewer additions and updates than the a1 and a7S III, as in many instances they are gaining the features that the latest a9 introduced. However, in addition to details such as outputting lens names in video file metadata, the a9 III gains the promised ability to use the camera’s full shutter speed range when continuous shooting. But beyond this, the a9 III gains a small array of feature expansions and refinements being added across the four cameras, including the ability to extract stills from video capture, to take advantage of its lack of rolling shutter.

Sony Electronics Delivers Firmware Updates including C2PA Compliancy as a Next Step to Ensure Authenticity of Images

SAN DIEGO, March 27, 2024 – Today, Sony Electronics delivers the highly anticipated firmware updates for the Alpha 1 (Ver. 2.00), Alpha 7S III (Ver. 3.00), Alpha 7 IV (Ver. 3.00), and after April 2024, the Alpha 9 III (Ver.2.00). The update contains some of Sony’s most impactful technology, including Camera Authenticity Solution, the proprietary in-camera digital signature and C2PA (Coalition for Content Provenance and Authenticity) format support1. Together, these tools will make it possible for news agencies to ensure the authenticity of images, contributing to industry efforts to protect creators, and society from fake imagery.

Additionally, the firmware updates include many requested features to improve everyday use. The update evolves shooting functions and post-shooting workflow and brings advanced movie features like breathing compensation. It also includes new remote-control capabilities, new features for professional applications, and expanded access to cloud services applications.

“There is nothing more core to our mission than listening to the voices of the photographers, videographers, and filmmakers who shoot with Sony Alpha cameras. We know this community has been asking for these updates, and we’re happy to deliver. Each of these updates are designed to promote ease of use for our creators and allow them to maximize the strengths of their cameras,” says Yang Cheng, Vice President, Imaging Solutions, Sony Electronics Inc. “We’re especially pleased to deliver C2PA compliancy with this update. This compliancy paired with our unique digital signature technology, allows us to offer the most secure and comprehensive solution to protect professional photographers, news agencies, and society from manipulated imagery.”

Camera Authenticity Solution

Last year, Sony announced its commitment to developing technology in its cameras to aid in the fight against manipulated imagery and AI-generated fakes. The severity of this issue is only increasing and it’s a complex problem that requires the focus and attention of our entire industry.

One critical part of the solution is making more Sony cameras C2PA compliant. C2PA is a Joint Development Foundation project, where Sony is a steering committee member. C2PA aims to develop an end-to-end open technical standard to provide publishers, creators and consumers with opt-in, flexible ways to understand the authenticity, and provenance of different types of media. The C2PA is a standards-setting body that will develop technical specifications on content provenance and authentication by certifying the source and history of media content. With this firmware update, the authenticity information embedded on images from Alpha 1, Alpha 9 III, Alpha 7S III, and Alpha 7 IV can be maintained from capture through publication. This provides professional photographers with the ability to preserve their digital signature from the camera, while tracking the editing history throughout revisions.

Another critical component of the solution is Sony’s in-camera digital signature technology2 that signs images in real-time. This new feature certifies the authenticity of an image at the point of capture and creates a ‘digital birth certificate’ that is retained throughout revisions. The signature contains metadata including 3D-depth information captured through the proprietary technology in the image sensor developed by Sony. This depth information can show if the image captured was of an actual 3D object, vs a photograph of an image or video, providing an extra level of protection and even more assurance of the content’s authenticity, and making Sony’s solution especially unique for photojournalists and news agencies.

Sony’s solution also helps protect the authenticity of content by including an Image Validation Site, which verifies the image even after edits have been made by C2PA-compliant editing software. This service confirms the authenticity of the photo was taken by a specific camera and that the object of the photo is 3D. This service will initially be offered to select news media agencies, expanding to other agencies at a later date.

File Transfer and Network Connectivity

Additional updates aimed to optimize the post-production workflow efficiency include improvements to International Press Telecommunications Council (IPTC) preset and File Transfer Protocol (FTP) transfer operability. To streamline processes for users, expanded cloud upload and application services will be available. Key updates include:

  • Cloud upload (camera direct) function allows users to upload images directly to the Sony’s Creators’ Cloud9. Key additional features include simplified camera software updates, direct camera registration to the Creators’ Cloud, and a flexible system for uploading, storing, and sharing content. Additionally, the capability to manage video and LUT files via mobile apps, along with the transfer of RAW files to smartphones, optimizes the creative process in fast-paced environments.
  • FTP Transfer Improvements: A “Protected Images Only” option for the Auto FTP Transfer and a “Protect Image in FTP Transfer” option for the FTP transfer function have been added. Available on the Alpha 1, Alpha 7S III, and Alpha 9 III.
  • Support for USB streaming10 on the Alpha 1.

Ricoh creates GR III HDF and GR IIIx HDF with highlight diffusion filters


Image: Ricoh

The Ricoh GR III HDF and GR IIIx HDF are variants of the company’s existing fixed-lens APS-C premium compacts. They feature a unique “highlight diffusion filter” instead of the ND filter fitted in the standard versions of both cameras.

Ricoh says the HDF has been developed using its inkjet technology and adds a diffusion effect to the images, particularly visible in highlight areas, comparable with a ‘black mist‘ filter. This, it says gives images “resembling those captured in film photography or vintage movies.”

By replacing the switchable ND filter in the optical path, the HDF effect can be turned on or off, depending on what you’re trying to achieve in each shot. By default, the Fn button will be set to engage and disengage the HDF fitler.

Other than the filter, the cameras gain more customization around white balance (which will come to the standard GR III and GR IIIx in a forthcoming firmware update). There’s also a Zone Select AF feature that lets you select a zone within which the camera narrows down when focusing.

The shutter buttons of the HDF versions of the cameras are dark silver, rather than black, to denote the difference, in every other respect, the HDF versions of the cameras are identical to their conventional versions.

Ricoh announces GR series cameras featuring built-in highlight diffusion filter

PARSIPPANY, NJ, March 27, 2024 — Ricoh Imaging Americas Corporation today announced the RICOH GR III HDF and RICOH GR IIIx HDF premium digital compact cameras. These new versions of the acclaimed RICOH GR III and RICOH GR IIIx cameras feature a newly-developed Highlight Diffusion Filter (HDF) that diffuses highlights for softer light, creating more expressive images with a sense of depth and emotion. The HDF, which can be turned on and off in a single action, allows the user to add a totally different kind of visual expression to captured images.

Developed using RICOH’s advanced inkjet technology cultivated over the years, this special- effect filter diffuses highlight areas and creates a blurred effect along the image’s edges, making it possible to produce images resembling those captured in film photography or vintage movies. Since the HDF can be instantly switched on and off with a single action, it lets the user effortlessly alternate between two completely different visual expressions — clear, sharply focused images characteristic of the RICOH GR series, and softer light, more expressive images captured by the HDF — depending on the subject or creative intention.

“The RICOH GR III HDF and RICOH GR IIIx HDF inherit the fundamental merits of our GR series – exceptional image quality, flawless point-and-shoot operation and outstanding portability,” said Ken Curry, president, Ricoh Imaging Americas Corporation. “The new GR HDF models give users a new creative option that expands the visual boundaries of snapshot photography.”

| Pricing and Availability |

The RICOH GR III HDF and RICOH GR IIIx HDF will be available in April at www.us.ricoh- imaging.com as well as at Ricoh Imaging-authorized retail outlets at a manufacturer’s suggested retail price of $1,069.95 for the RICOH GR III HDF and $1,149.95 for the RICOH GR IIIx HDF.

| Main features of the new RICOH GR III HDF and RICOH GR IIIx HDF |

  • Single-action switching to the new, built-in HDF to create softer light, more expressive images:
    The new GR HDF versions incorporate the newly developed HDF (Highlight Diffusion Filter) to emphasize highlights and produce softer light and more expressive images. Developed using RICOH’s advanced inkjet technology cultivated over the years, this special-effect filter diffuses highlight areas and creates a blurred effect along the image’s edges, making it possible to capture images resembling those captured in film photography or vintage movies. Since the Highlight Diffusion Filter can be instantly switched on and off with a single action, it lets the user effortlessly alternate between two completely different visual expressions — clear, sharply focused images characteristic of the RICOH GR series, and softer light, more expressive images captured by the HDF — depending on the subject or creative intention. This creative versatility expands the visual boundaries of snapshot photography.
  • The color of the shutter-release button has been changed to dark silver to subtly differentiate the HDF models from other GR series models and to symbolize the effortless shift of visual expression. The default setting of the Fn (Function) button has also been changed to the ON/OFF switching of the HDF,* allowing the user to quickly engage the HDF with a press of a button.
  • The user can pre-program up to three white-balance settings as the base white balance.** It is also possible to couple the base white balance with the White-balance Fine Adjustment function.
  • The new models feature Zone Select AF,*** which automatically sets the focus at the most appropriate point within the image area after the user shifts the 3X3 focus area to the desired zone.

* The user can also select another function as the default setting of the Fn button.
** This function can be added to all RICOH GR III- and GR IIIx-series models using function- expansion firmware, which is scheduled to be released along with the market launch of these new models.
*** The 3X3 focus area is identical in size to that of the Auto-area AF (Center) mode.
