New standards for full-frame cameras

With impressive image quality in 33 megapixel resolution, video recording in 4K 60p, precise handling and fast sharing functions, the Sony Alpha 7 IV sets new standards for full-frame cameras as the perfect hybrid camera. Creative and professional photographers will always have Sony's best technology at hand to bring their ideas to life with the α 7M IV and its premium real-time autofocus for still and video shooting.

Unparalleledimage quality
The rear-exposed 33-megapixel Exmor R full-frame sensor with high-speed readout, high sensitivity, and highly accurate color reproduction, combined with the high processing power of the new Bionz XR image processor, ensures outstanding image quality. Thanks to high ISO sensitivity (expandable to ISO 50-204800 for photos and 100-102400 for videos) even in low light.

In addition to the two classic RAW and JPEG formats, the HEIF format (High Efficiency Image File) is also available for photos. Thanks to this format's inherent 4:2:2 color sampling and 10-bit color depth, even the finest gradations are reproduced naturally and realistically.

The 7 IV has two media slots that support UHS-I and UHS-II SDXC and SDHC cards. In addition, one of the slots is compatible with CFexpress Type A memory cards. This means that high read and write speeds are also possible without any problems.

Improved selection and editing

The Sony 7 IV offers ten unique in-camera presets for photos, videos, and livestreams. So you can create your own individual picture looks already in the camera and share your images with the world quickly and easily without any complex post-processing.

The optionally adjustable Soft Skin effect provides a radiant complexion, reduces wrinkles, skin irritations and dull areas and emphasizes eyes and mouth.

Autofocus rethought
Faster, more accurate and more precise: the advanced hybrid autofocus recognizes subjects (human, animal and bird) thanks to the latest real-time tracking technology and reliably keeps them in focus. Even with fast and unpredictable movements. Via touch, real-time tracking can be easily applied to any subject in the frame and activated in addition to eye autofocus when detecting eyes.

Focus functions already familiar from the Sony Alpha 1 and α 7S III, such as focus switching or a user-defined subject tracking sensitivity, offer new, creative possibilities in video composition.

The powerful memory buffer allows up to 800 frames at up to 10 frames per second with AF/AE tracking. So you'll never miss a subject again! The AF Assist function supports focus transitions, ensuring a clean switch between auto and manual focus.

The 24-70mm F2.8 Art has been further developed on all levels:
Optical performance, functionality and portability.
The SIGMA 24-70mm F2.8 DG DN II | Art has been significantly enhanced compared to its predecessor. The most advanced technologies available to SIGMA in design and production have been used.

Compared to its predecessor, the SIGMA 24-70mm F2.8 DG DN II | Art has an improved resolving power over the entire zoom range. It also benefits from functional improvements, such as the newly added aperture ring and the high-speed autofocus with newly developed HLA drive (High-Response Linear Actuator).

In addition, the Lens is approx. 7% smaller and 10% lighter than its predecessor. The new 24-70mm F2.8 II Art is therefore a versatile and powerful tool with which photographers and filmmakers can unleash their creative potential.

Key features:
1.)
Top performance that lives up to the reputation of a top model
The new SIGMA 24-70mm F2.8 DG DN II | Art is the successor to the SIGMA 24-70mm F2.8 DG DN | Art, which is renowned for its high optical performance, and has further improved resolution across the entire zoom range. It delivers the highest image quality even at open aperture and the high speed of F2.8 ensures a soft and harmonious bokeh. The Lens therefore offers maximum performance in almost all shooting situations. The short closest focusing distance further expands the creative possibilities. Flares and ghosting are excellently corrected and focus breathing is largely minimized. This means that the outstanding creative possibilities of this lens can be fully utilized in both photo and video applications.

High optical performance across the entire image and zoom range
The optical design of the lens comprises 6 FLD and 2 SLD glass elements. In addition, 5 aspherical lens elements are used. Aberrations are thus reliably suppressed over the entire zoom range. Sagittal coma flares in particular are well controlled in order to achieve a consistently high resolution right up to the periphery of the image. The effective correction of lateral chromatic aberration means that high-resolution images free of color fringing can be achieved.

Equipped with 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. SIGMA's production facility in Aizu, Japan, has the high-precision aspherical molding technology that allows it to produce the thin, highly polarized aspherical lenses required for this purpose. This has led to a higher degree of freedom in optical design.

Excellent close-up capability
The Lens offers an excellent close-up focusing distance of just 17cm in the wide-angle range and a maximum magnification of 1:2.7. These factors create potential for creative close-ups.
Note:
When taking close-ups in the wide-angle range, the lens hood should be removed to avoid touching the subject.

Low susceptibility to flares and ghosting
Flares and ghosting, which impair image quality, have been optimized for all lighting conditions using the latest simulation technology. In addition, a nano-porous and super multi-layer coating has been applied to the front lens to prevent flares and ghosting as far as possible. This enables brilliant, high-contrast images to be taken even in unfavorable lighting conditions.

Minimized focus-breathing
The optical design effectively suppresses focus-breathing. The changes in the image angle when focusing are reduced to a minimum, resulting in natural-looking video recordings.

2.)
Betterportability and extended features
The SIGMA 24-70mm F2.8 DG DN II | Art is approx. 7% smaller and 10% lighter than its predecessor. The user-friendliness has been improved with an additional aperture ring and two AFL buttons. Despite its greater compactness and improved features, the Lens offers SIGMA's renowned high build quality. With an uncompromisingly precise and robust construction, as you would expect from a professional photographic tool.

Better handling
While the number of lens elements used has remained the same compared to the previous model, the overall length has been shortened thanks to the modern optical design. In addition, the more efficient mechanical design has resulted in a portable Lens with a maximum diameter of 87.8mm, a length of 120.2mm and a weight of 745g*.
Version with L-mount.

Outstanding processing quality
The robust internal structure and the use of high-precision metal parts ensure high stability and durability in professional use. At the same time, the size and weight of the Lens have been reduced. The design has been consistently geared towards the durability and reliability of the Lens.

Aperture ring with "de-click function"
Many demanding users appreciate the ability to set the aperture directly on the aperture ring of the Lens. The SIGMA 24-70mm F2.8 DG DN II | Art therefore once again offers an aperture ring. Thanks to its "de-click function", this feature is also interesting for filmmakers, as the aperture can be adjusted smoothly and silently in this position. Those who prefer to set the aperture on the camera body can use the aperture ring's lock function and are protected against accidental adjustment.

Equipped with two AFL buttons
Unlike its predecessor, the Lens now has two AFL buttons whose accessibility has been optimized for shooting in portrait and landscape format. These buttons can be assigned individual functions with compatible cameras.

3.)
Professional functions, including high-speed autofocus
The SIGMA 24-70mm F2.8 DG DN II | Art has a high-speed AF with HLA drive in order to offer maximum performance in every shooting situation. Other features, such as dust and splash protection, the water and oil-repellent coating of the front lens and the zoom lock switch complete the professional features of the lens.

With HLA linear actuator
The Lens is equipped with an HLA (High-Response Linear Actuator) linear motor for the
AF drive. Thanks to the powerful HLA, the maximum
drive speed is more than three times that of the previous model*, ensuring
responsive AF shots.
*compared to the maximum drive speed of the SIGMA 24-70mm F2.8 DG DN | Art, the actual AF focusing time may vary

Protected from external influences
In addition to the dust and splash-proof Body*, the front lens
of the Lens has a water and oil-repellent coating. Even
in difficult shooting conditions, you can take pictures without worrying.
* The lens is protected against dust and splash water, but is not waterproof.

Equipped with zoom lock switch
The lens is equipped with a zoom lock switch that locks the lens in the wide-angle range and prevents the tube from extending unintentionally due to its own weight. The lock can be released not only via the switch, but also by turning the zoom ring, which enables flexible handling even for spontaneous shots.

Includes lens hood and case
The specially adapted lens hood LH778-05 is included with the SIGMA 24-70mm F2.8 DG DN II | Art and is securely locked with a quick twist. The Lens is supplied in a matching case for storage and safe transportation.
