Sigma announces 24-70mm F2.8 DG DN II for Sony E and Leica L mounts

Sigma has announced the 24-70mm F2.8 DG DN II, a second-generation, mirrorless-only fast standard zoom lens as part of its Art series of premium optics.
The new lens is a fraction smaller and around 10% lighter than the existing lens. And while a 19 element, 15 group design with 6 fluorite-like FLD elements and 2 SLD elements might sound familiar, the use of five aspheric elements, rather than three, shows it to be a new optical formula.
The new lens, which arrives five years on from the original, uses a “High-Response” linear motor to drive autofocus, rather than the stepper motor that was used before.
Sigma says the sharpness and contrast performance outdoes the existing lens, with a combination of modern design techniques, new glass materials and improved manufacturing capabilities coming together to deliver a lens with less coma and better optical qualities.
The minimum focus distance drops by 1cm to 17cm (6.7″) which also means the maximum reproduction ratio nudges up from 0.34x to 0.37x. It retains its 82mm filter thread diameter.
In terms of handling, the 24-70mm gains a second AFL button, so that one is within reach whether the lens is being held in the portrait or landscape orientation. In addition to its AF/MF switch and zoom lock, the version II adds a switch to lock the aperture ring in or out of the ‘A’ position, and a switch to de-click the ring’s movement.
The Sigma 24-70mm F2.8 DG DN II | Art will be available from the end of May at a recommended price of $1,199, representing a $100 increase since the 2019 version’s launch.
We had prepared a sample gallery with the 24-70mm F2.8 DG DN II but on close examination found the results didn’t reach the quality we expected. We have decided not to publish the results as we do not believe they accurately represent the product’s performance. We hope to get the opportunity to shoot another gallery in the coming days.
SIGMA Announces 24-70mm F2.8 DG DN II | Art Lens, an Upgraded Follow-Up to its Popular Standard Zoom for Full-Frame Mirrorless Cameras
Ronkonkoma, NY – May 16, 2024 – SIGMA Corporation of America, the US subsidiary of SIGMA Corporation (CEO: Kazuto Yamaki. Headquarters: Asao-ku, Kawasaki-shi, Kanagawa, Japan) is pleased to announce the SIGMA 24-70mm F2.8 DG DN II | Art lens. This is the second generation of the highly successful SIGMA 24-70mm F2.8 DG DN | Art. The new lens has undergone a significant evolution, including enhanced optical performance, AF speed and operability, while also achieving a more compact size than the original.
The advancement of optical design has shortened the total optical length, and the lens barrel has been made slimmer by thoroughly downsizing the zoom mechanism. In addition, the lens barrel has been downsized by placing buttons and switches directly on the lens barrel. The weight has been reduced by approximately 10% compared to the SIGMA 24-70mm F2.8 DG DN | Art. By driving the lightweight focus group with the high-thrust HLA, autofocus is significantly swifter than the original version.
6 FLD glass elements, 2 SLD glass elements, and 5 double-sided aspheric lenses are used. Aberrations are highly corrected through advanced optical design made possible by advanced basic technologies in both design and manufacturing, including the use of new glass materials and aspherical lenses with thin walls and high degrees of asphericity. In particular, sagittal coma flare is heavily corrected to achieve MTF characteristics surpassing those of the highly-acclaimed 24-70mm F2.8 DG DN | Art. The high level of flare resistance also results in point images, such as stars, at the periphery of the image being closer to ideal points.
A close-focusing distance of 6.7 inches (17cm) at the wide end at 1:2.7 magnification*1 adds to the versatility of this lens, and the addition of a click/de-click and lockable aperture ring, along with an additional AF-L button for vertical orientation still or video capture, are additional enhancements of this second-generation lens. The zoom lock switch, which disengages when zooming, is inherited from the SIGMA 24-70mm F2.8 DG DN | Art. Manual focus can be switched between Linear and Non-linear response (L-Mount only.) A splash- and dust-resistant structure, plus water and oil-repellent coating on the front element, add to durability.
The new SIGMA 24-70mm F2.8 DG DN II | Art lens builds on the success and popularity of the original 24-70mm F2.8 DG DN | Art, and offers an impressive upgrade with added features and performance in a more compact package that is perfect for working pros in both still and video applications. Offered in Sony E-mount and L-Mount, the lens will be available through authorized retailers in late May 2024 and will sell for $1,199.

The SIGMA 24-70mm F2.8 DG DN II | Art is SIGMA’s flagship lens that has evolved significantly from the previous model by incorporating the most advanced technologies available to SIGMA from design to production. Compared to the previous SIGMA 24-70mm F2.8 DG DN | Art, the SIGMA 24-70mm F2.8 DG DN II | Art has improved resolving power throughout the entire zoom range, and also benefits from functional enhancements such as the addition of an aperture ring and high-speed AF with a redesigned AF motor, HLA (High-response Linear Actuator). The lens is also approximately 7% smaller and 10% lighter. This 24-70mm F2.8 Art zoom is a versatile and high-performance tool that will help photographers and filmmakers unlock their creative potential.
[Key Features]
1. Rendering performance worthy of the flagship name
The SIGMA 24-70mm F2.8 DG DN II | Art is the successor to the SIGMA 24-70mm F2.8 DG DN | Art, which is known for its high optical performance, and has further improved resolution throughout the zoom range. The lens has high sharpness throughout the entire image from its maximum aperture, even on high-resolution cameras. Focusing on enhancing its rendering performance, the brightness of F2.8 produces a large, beautiful bokeh effect, and allows users to experience the power of a flagship lens in all types of visual expression. In addition to its advanced close-up capability and resistance to flare and ghosting, the lens is designed to minimize focus breathing.
High optical performance across the entire image and zoom range
The optical design of the lens includes 6 FLD glass elements, 2 SLD glass elements, and 5 aspherical lens elements to thoroughly suppress various aberrations throughout the entire zoom range. In particular, sagittal coma flare has been well controlled to achieve consistently high resolution all the way to the periphery of the image. By also effectively correcting lateral chromatic aberration, high resolution, beautifully rendered images can be achieved, free from color fringing can be achieved.
Incorporating 5 aspherical lenses
The use of 5 high-precision aspherical lenses enables both high optical performance with minimal aberration correction and a compact optical design. The SIGMA’s only manufacturing base, the Aizu factory’s ultra-high-precision aspherical molding technology makes it possible to produce the thin, highly polarized aspherical lenses that are essential for the construction of this lens. This has brought about a higher degree of freedom in optical design.
Excellent close-up capability*2
The lens has excellent close-up capability with a minimum focusing distance of 17cm / 6.7in. at the wide end and a maximum magnification ratio of 1:2.7. This is useful when composing close-up shots of a subject, or when shooting in tight spaces where it is difficult to get a good distance from the subject.
Designed to minimize flare and ghosting
Flare and ghosting, which reduce image quality, have been largely eliminated using advanced simulation technology, ensuring the lens renders rich, high-contrast results in all conditions. In addition, Nano Porous Coating and Super Multi-layer Coating have been applied to help suppress flare and ghosting to the utmost degree. High backlight resistance enables clear and sharp images under any lighting conditions.
Minimal focus breathing
The lens has been designed to suppress focus breathing. The change in angle-of-view due to focus shift across the entire zoom range is minimized, creating a natural-looking focus pulls when recording video.
2. Improved portability and expanded feature set
The body of the SIGMA 24-70mm F2.8 DG DN II | Art is approximately 7% smaller in size and 10% lighter in weight than the previous model, while improving usability by adding an aperture ring and two AFL buttons. Despite the reduction in size and added features, the lens maintains SIGMA’s renowned excellent build quality, with the uncompromisingly precise and robust construction expected of a professional photographic tool.
Highly portable lens body
While the number of lens elements used in its construction is the same as that of the previous model, the overall length has been shortened owing to an advanced optical design. In addition, the more efficient mechanical design has resulted in a highly portable lens body with a maximum diameter of 87.8mm / 3.5in., length of 120.2mm / 4.7in., and weight of 745g / 26.3oz.*3
Excellent build quality
Simultaneously focusing on reducing the size and weight of the lens body, the use of metal parts for the zoom extension unit and other parts, as well as the robust internal structure ensure rigidity during use, such as when operating the ring, pressing buttons, and carrying the lens. The design emphasizes the lens’ longevity and reliability as a tool, which cannot be achieved by solely pursuing a compact and lightweight body.
Equipped with an aperture ring
The lens is equipped with an aperture ring as well as an aperture ring click switch and an aperture ring lock switch, allowing for aperture operation suitable for various shooing situations.
Equipped with two AFL buttons
The lens is equipped with two AFL buttons*4, to which a range of functions can be assigned via the menu on selected cameras, one more than the previous model. In addition to the side, the additional button has been positioned on the top to facilitate button operation when the camera is held in vertical orientation.
3. A wealth of functions including high-speed autofocus
In addition to high-speed AF with HLA (High-response Linear Actuator), the SIGMA 24-70mm F2.8 DG DN II | Art has a full range of features including weather resistance such as a dust and splash resistant structure*5 and water and oil repellent coating, as well as a zoom lock switch. The lens delivers the best possible results in every shooting situation.
Incorporating a linear motor HLA
The lens incorporates a linear motor HLA (High-response Linear Actuator) for the AF actuator. The high output HLA makes the maximum drive speed more than three times faster than the previous model*6, ensuring responsive AF shooting.
Dust and splash resistant structure and water and oil repellent coating
In addition to a dust and splash resistant structure, the front element of the lens features a water and oil repellent coating, allowing users to shoot without concerns even in harsh outdoor environments.
Equipped with a zoom lock switch at the wide end
The lens is equipped with a zoom lock switch that locks the lens at the wide end and prevents the barrel from extending unintentionally under its own weight. The lock can be released not only by the switch but also via zoom operation, allowing for flexible handling of even impromptu shooting.
Includes petal-type hood with lock
A dedicated petal-shaped hood is supplied. A locking mechanism is provided for secure attachment.

Accessory Roundup: lights, iPads, bags and more

Images: Vanguard, Apple, Elinchrom |
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

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

Image: Godox |
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

Image: Vanguard |
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

Image: Wandrd |
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
![]() |
Image: Apple |
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.
![]() |
Image: Apple |
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.
![]() |
Image: Peak Design |
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

Photo: Richard Butler |
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.
