We’re at Sigma’s pre-CP+ event at its headquarters in the suburbs of Tokyo. CEO Kazuto Yamaki is talking and we’ll be reporting live on what he reveals.

About the company

He says they’ve been working hard to provide “the best of the best.” But, since he took over the company on 2012, the image quality of smartphones has increased and “the importance of the dedicated camera is gradually being questioned.”

This caused him concern, he says. But he found himself encouraged when he went back to the founding ethos of his father: “technological innovation is an art in itself.”

He says the company will focus on “technology, craftsmanship and art.” To reflect this, the company is introducing a new look and new logo, with the tag-line: “The art of engineering, engineering for art.”

As part of this, Yamaki says the company is establishing the Sigma Foundation that will promote the art of photography. The foundation’s first actions will be to publish photo books by two photographers: Sølve Sundsbø and Julia Hetta.

But, he says the company’s focus will remain the same: “to develop, manufacture and deliver the very best products to our customers.”

“Since 1973 we have been making all our products in Aizu, Japan,” he says, “and we remain committed to the people and the community of Aizu.”

Two new lenses:

The first lens is the 16-300mm F3.5-6.7 DC OS, an 18.8x zoom lens for APS-C, as part of its Contemporary range of lenses.

He describes the design as compact and lightweight, with a diameter of 73.8mm and a length of 121.4mm. It weighs 615g (L-mount). The lens is ideal for travel, landscape, street and family photos, where flexibility is important, he says.

The autofocus is driven by the company’s HLA linear motor and the optical stabilization can deliver 6.0 stops of shake compensation at the wide end.

It can deliver a 1:2 magnification ratio at 70mm. It will be available for L-mount, Sony E-mount, Fujifilm X-mount and Canon RF-mount. It will cost $699 and be available in April.

Sigma-300-600mm-F4-DG-OS-sports

The second lens is a Sigma 300-600mm F4 DG OS Sports. The World’s first zoom to reach 600mm with a maximum aperture of F4.

He says they aimed to make it compact and lightweight enough for handheld use. It weighs around 4Kg and is 467.9mm long. It has a diameter of 167mm.

The optical stabilization is able to deliver 5.5EV of correction. It has 28 elements in 21 groups include six FLD elements and one SLD element. The lens has a switch to change stabilization modes, for when you’re panning.

The lens is an internal zoom design, minimizing shifts in the center of gravity. It can take internal filters. It will be available for both L-mount and E-mount. It will cost $5999, and is also available in April.

New camera: Sigma BF

“Smartphones are now the most used camera in the world,” says Yamaki: “the very raison d’etre of dedicated question is brought into question.”

While situations like sports and wildlife photography still require a dedicated camera, it’s less obvious whether a dedicated camera is needed for day-to-day photography. “We believe it is,” he says.

Modern digital cameras are not compatible with frequent day-to-day use. We wanted to create a camera that was small, simple and well-suited to everyday use.

“An everyday system camera for creative minds.”

L-mount camera with 24MP CMOS sensor. He says the design concept is one of “radical simplicity.”

He highlights three features: Unibody construction, Single-finger interface and Dual Layer menu system.

The body is a unibody/monocoque construction. It takes over seven hours to mill the camera from a single ingot. On one side there is a strap lug, on the other a USB 3.2 10Gbps port. Beyond this, just a tripod socket and battery compartment.

There is no memory card slot. Instead. 230GB of internal memory. This allows storage of up to 14,000 JPEGs, 4300 DNG Raws and over 2.5 hours of video at the highest bit-rate.

Single-finger interface:

He suggests the complexity of modern camera interfaces stems from them being based on film camera operation. He says they’ve simplified everything to allow everything other than the shutter button to be operated with your thumb. The buttons on the back use piezoelectric actuators to provide haptic feedback as you operate it.

The BF costs $1999 and will be available in April. We’re told we’ll be able to get our hands on a working sample shortly.

He points out that many menus have a great many options and can require a lot of exploring and button pressing. On the BF they have simplified all the options into two menu screens: the main menu screen with all the key shooting parameters: aperture, shutter speed, ISO, exposure comp and color modes. At the top of the screen: aspect ratio, AF mode and white balance.

Separately, there is a second screen with settings you change less often are grouped in a Options menu. More complex settings are stored one layer deeper, in a more conventional menu structure.

He acknowledges it may take some time to learn this new system, especially if you already know how to use another camera, but in time he says you will learn to enjoy the BF. “This is the easiest camera to use,” he says.

The BF includes two new color modes, in addition to the ones on the existing fp and fpL models. These are Calm and Rich modes, one of which is subtle, the other quite bold.

“The BF is chiefly a photo camera but it can shoot video,” Yamaki says. It can shoot up to 6K/30 in H.264, H.265 and Leica L-Log formats.

The BF will be available in black or silver, with silver versions of the I-series primes available in L-mount, to match. The BF weighs 388g (without battery).

It features a hybrid AF system combining phase detection and contrast detection.

March Editors' photo challenge announced: Water


While visiting Dry Tortugas National Park, located 109km west of Key West, Florida, I looked down from the top of Fort Jefferson and saw this group of snorkelers just off Garden Key. Moments after this photo was taken, one of the snorkelers had the bad luck of being stung by a Portuguese man o’ war.

Accessory Roundup: lights, iPads, bags and more

Accessory Roundup: lights, iPads, bags and more

CP+ may have ended last week, but that apparently hasn’t stopped the flood of accessory news. Today, we’ll look at a few lights, bags, computers and more, but first, let’s see what’s on sale.

Second-gen Goodness

Canon’s Stacked sensor flagship, the EOS R5 II, is currently on sale for $300 off MSRP. We reviewed it late last year, and came away very impressed – it’s a camera that excels at nearly everything.

Panasonic’s S5II isn’t quite as performant, but it’s still quite a good camera. It’s also substantially cheaper than the EOS R5 II, especially given the current sale that gets you $500 off.

Let there be lights

Godox’s latest light for videographers and photographers is the Litemons C30. It’s a tiny LED panel weighing 248g that packs an internal battery capable of putting out 30W of light for up to 45 minutes. A USB-C port lets you recharge the battery or run the light for an extended period of time.

There are two versions of the light – a bicolor model, which costs $59, and an RGB model that will run you $89.

If you need something a little more powerful, there’s the recently released Elinchrom LED 100 C, a continuous RGB light with an integrated 72Wh battery that provides up to 40 minutes of power in the field. It comes with a diffusion dome and an adapter for Profoto light modifiers and can be charged via USB-C.

On the level

Ball-head tripods are great if you want to easily level your tripod without messing around with leg length, but what if you already have a tripod that you like? Vanguard’s LVL accessory might be for you. It’s designed to sit between your sticks and your tripod’s head, adding a bit of height and letting you level your tripod head in a matter of seconds.

Vanguard makes several sizes, so it should be compatible with a wide range of tripods. The smallest, the LVL 42, has a 42mm base and can support up to 20kg (44lb), while the LVL 75 can support up to 40kg (88lb) – just make sure the rest of your tripod can handle that much weight too.

In the bag

If you want to carry around some camera gear without using a massive backpack, Wandrd’s Stratus Photo 18L may be the bag for you. It’s relatively small and has built-in organization for your camera gear, as well as access hatches on both the right and left-hand side. It’s made of weather-resistant materials and has load-adjustment straps and a chest strap, which should let you carry it comfortably even if you’ve got it filled with gear.

New affordable iPads

People don’t always think of the iPad as a photographic tool, but nowadays Apple’s tablets have a lot of processing power and can run many of the apps photographers use on their desktops. The company’s entry-level models – the iPad Air and the plainly-named iPad – have just gotten updates that make them better than ever. The Air gets the laptop-class M3 chip, as well as a new, optional keyboard with a bigger trackpad, function row and aluminum design. The M3 iPad Air starts at $599, and the new keyboard costs $269.

The cheaper iPad, meanwhile, gets the A16 chip from the iPhone 14 and 14 Pro. While it’s not as powerful as the M-class chips and doesn’t support Apple’s suite of AI features, it should still be plenty for light photo editing and organization. Its base storage has also been doubled from 64GB to 128GB. It starts at $349, which is what its predecessor sold for ever since Apple cut the price by $100 in 2024.

That wasn’t all Apple announced this week, though…

Get caught up

Some accessory news is so big that it gets its own article during the week, but we’d feel remiss not also mentioning those products here.

As an example, Apple’s new computers. The company announced updates to its entry-level MacBook Air and top-of-the-line Mac Studio this week, adding its latest processors. The MacBook Air has enough processing power to handle the typical Photoshop and Lightroom tasks that most photographers need, all while being hyper-portable, while the Mac Studio can handle the highest-end photo and video editing tasks.

Also announced this week: Peak Design’s Roller Pro, the company’s first piece of roller luggage. It’s a bit of a hybrid between a hardshell case and a softshell one, with plenty of padding and a front sleeve that can hold a laptop and other everyday carry items. You can read our full coverage of it here.

It’s currently being sold via Kickstarter for a discount over its $599 MSRP, but the usual disclaimer applies: Remember to do your research with any crowdfunding project. DPReview does its best to share only the projects that look legitimate and come from reliable creators, but as with any crowdfunded campaign, there’s always the risk of the product or service never coming to fruition.

Sony's content authenticity system isn't just for pro cameras anymore

Sony's content authenticity system isn't just for pro cameras anymore

Sony has released a firmware update that brings its Content Authenticity Solution to the a7 IV. The company announced a similar update for the a1 II, a1 and a9 III in January. However, this is the first time the tool to authenticate images will be available on something other than high-end, professional-grade cameras.

Software Ver. 5.00 for the Sony a7 IV adds support for the “Write Digital Signature” function for still images. This function allows photographers to add an electronic signature to their images to prove that they were taken with that camera. Authenticity tools such as this are becoming increasingly important with the growing prevalence of generative AI-created imagery and, as a result, the spread of fake images.

Of course, as with the update for the three pro-grade cameras in January, there are some caveats involved. The Digital Signature function requires a paid license and is only available for certain media outlets, not the general public. Unfortunately, Sony still hasn’t provided any additional information on if or when it will be available for general consumers. On the firmware update page, Sony simply says that the “timing for the provision of paid licenses to customers other than certain media outlets is yet to be determined.”

Even though the current usability is limited, Sony rolling this out to consumer models is a step in the right direction. The Content Authenticity information page also says that “more camera models will be supported in due course,” so it sounds like we should see additional cameras with the tool at some point. If Sony makes the feature more widely available beyond media outlets, the Digital Signature feature will already be on cameras and ready for use.

If you want to be prepared, or happen to work for one of the select media outlets, the Sony a7 IV firmware update Ver. 5.00 is now available for download.
