Sony temporarily made a7 IV firmware version 1.1 available as shared below. The firmware was since taken down, with this notice provided:

"It was confirmed that some products that updated may not operate properly in some cases. Distribution will be suspended until we can inform you of modified version. (August 24, 2022)" [Sony]

I expect that we will see this update become available again very soon.

Here is the original press release from Sony:

New Alpha 7 IV Firmware Update Enables Lossless RAW File Options and Improved Accuracy and Operability

SAN DIEGO, CA – August 23, 2022 – Sony Electronics Inc. today announced the v1.1 firmware update for the Alpha 7 IV full-frame mirrorless interchangeable lens camera, adding Lossless Compressed RAW in three sizes for still images, shutter speed and ISO setting retention, touch shutter function, improved Eye AF (autofocus) accuracy and more. ? ?

The update adds Lossless Compressed RAW files in S, M and L (small, medium or large) file sizes – a highly requested feature. Selecting L size preserves the same image quality as an uncompressed RAW format while significantly reducing the file size. The M and S sizes record fewer pixels than the L size, providing even smaller RAW file sizes.

Alpha 7 IV v1.1 allows photographers to retain shutter speed and ISO settings for flash photography. This newest update also offers a Touch Shutter Function and improves the accuracy of the Eye AF feature.

Other updates in the Alpha 7 IV v1.1 include:

• The ability to record the camera's serial number in the metadata of video files
• Improved operability of Wi-Fi connections
• A one-minute setting added to Power Save by Monitor menu
• The ability to brighten the viewfinder display according to the ambient brightness
• Improved operational stability of the camera

Development Announcement

TAMRON Announces Category-Disrupting, Fast-Aperture Standard Zoom 20-40mm F/2.8 Di III VXD (Model A062)

New lens is smallest and lightest in its class* and opens new video opportunities

August 17, 2022, Commack, NY - Tamron announces the development of the 20-40mm F/2.8 Di III VXD (Model A062), a fast-aperture standard zoom lens for Sony E-mount full-frame mirrorless cameras. The lens is scheduled to launch in Fall 2022. Due to the current global health crisis, the release date or product supply schedule could change.

Overview of the 20-40mm F/2.8 Di III VXD (Model A062) features

The 20-40mm F2.8, TAMRON's latest innovation, is an unparalleled new fast-aperture standard zoom lens that can be easily carried around for everyday shooting for both still images and video. Designed for Sony E-mount full-frame mirrorless cameras, the lens was created in aggressive pursuit of portability that is ideal for everyday use. Starting from 20mm at the ultra wide-angle end and covering up to 40mm in the standard focal range, it is the smallest and lightest in its class. The 20-40mm F2.8 delivers beautiful images across the entire zoom range and is great for still photography and for creating vlogs and other video content. The lens incorporates TAMRON’s VXD (Voice-coil eXtreme-torque Drive), an AF drive system using a linear motor focus mechanism. The VXD boasts superior quietness and agile performance and achieves high-speed and high-precision autofocus. With an MOD (Minimum Object Distance) of just 6.7” and maximum magnification ratio 1:3.8 at the wide end, the lens provides exceptional close-range shooting capability, offering the added feature of wide macro photography.

Main features

1. Fast F2.8 aperture, compact size and exceptionally versatile 20-40mm zoom range

The 20-40mm F2.8 is TAMRON's innovative creation of a new standard zoom lens, born from the unbridled desire to produce a compact size that can be carried around easily. It delivers a fast F2.8 aperture across the entire zoom range from 20mm to 40mm and achieves a class-leading compact and lightweight design at just 3.4” and 12.9 oz. At the longest zoom end, the lens offers a standard focal range of 40mm, handy for everyday shooting of snaps, portraits, and food photos. Meanwhile at the wide end, the ultra-wide 20mm focal length lets users enjoy a broad range of photography including stunning and powerful natural landscapes that make use of the unique ultra wide-angle perspective, something that cannot be expressed as readily with a fast-aperture standard zoom lens that starts at 24mm.

Let's talk about "reach", which I'll loosely define as the number of pixels remaining in the desired composition, rendering a subject large when the image is viewed at 100% resolution. Longer focal lengths are the ideal method for accomplishing "reach" with any camera, but the term "reach" is usually reserved for when the longest available lens focal length is not long enough for the desired composition.

This article evolved from its conception, and with crop factors, focal lengths, extenders (teleconverters), pixel density, and reach in the discussion, I take on the challenge of omitting confusion.

To get started, I'll share the original purpose behind this article. A friend is on a mission to obtain sharper, higher-resolution images of distant birds. He is using an EOS R5, currently Canon's highest resolution mirrorless camera, with a Canon EF 600mm f/4L IS III USM Lens and EF 1.4x III Extender mounted.

The primary question is, will the Canon EOS R7 and 600mm F4 lens provide better final image quality than the R5, 600mm F4 lens, and 1.4x extender combination? I'll answer that specific question while providing more widely relevant information.

An important clarification is that an APS-C imaging sensor's smaller size does not provide more "reach" than a full-frame imaging sensor. Instead, it crops away a portion of the image circle. While the cropping provides a significant 1.6x narrower angle of view, simulating better reach in the viewfinder, a higher pixel density on the imaging sensor is what provides reach. That most APS-C imaging sensors have a higher pixel density than the full-frame camera models means that photographers touting APS-C cameras as having a reach advantage are usually right, regardless of why they think that.

Mounting a 1.4x extender behind the lens on a full-frame camera makes up for much, but not all, of the full-frame vs. APS-C angle of view difference just discussed. That comment addresses the final framing available but not the reach. When focal length limited, the max available framing is often less important as cropping is likely still necessary. Again, for this article's primary purpose, we are looking for the option that affords the most reach.

For reach, high pixel density is paramount.

A simple way to measure pixel density is to view the pixel size spec. For example, the EOS R5 has a 4.39µm pixel size, and the Canon EOS R7's spec is 3.20µm. Modern image sensors are gapless, so a smaller pixel size correlates to a higher pixel density, and in this example, the R7 has a significantly higher pixel density than the R5.

Interesting is that the R7 pixels are 1.37x smaller than the R5 pixels — creating R7 reach nearly equivalent to that of the R5 with a 1.4x mounted behind the same focal length. The full-frame camera will provide a wider angle of view (1.4x vs. 1.6x) and will provide more pixels overall (45 MP vs. 32.5 MP). Still, when the images are zoomed in to a 100% pixel level view, individual subjects are contained in approximately the same number of pixels from both options. Crop both images to the same composition within the APS-C angle of view, and the images will be nearly identical — assuming that the pixels from both solutions have equivalent quality.

Pixel-level image quality can vary from factors that include low pass filter strength (or lack of this filter), processing applied to the base RAW image, etc.

Another important clarification is that global statements about extender performance must be carefully crafted, as every extender model performs differently with every lens it is mounted behind. Magnifying the image circle of a lens that barely out resolves the imaging sensor may push it past that resolving point, resulting in some amount of blur imparted in an image.

I've long wanted to create an exhaustive extender comparison, but that means testing every camera, lens, and extender combination available, an unrealistic endeavor that is sure to have results impossible to describe concisely. Testing only the lens manufacturer's latest extender models with each lens test provides relevant, valuable results.

When comparing reach, the pixel-level image quality matters, and the R7 and R10 are both excellent in this regard. Always true is that extenders magnify lens aberrations. However, so do higher density imaging sensors.

Another universal truth is that 1.4x extenders reduce the maximum aperture, the focal length to entrance pupil diameter ratio, by one stop (and a two-stop reduction comes with 2x extenders). That one stop is approaching the difference in the amount of light captured by an APS-C sensor vs. the full-frame variant — before any cropping.

Extenders can impact geometric distortion. For example, the Canon RF 1.4x Extender introduces modest barrel distortion. Barrel distortion magnifies the details in the center of the frame more than those in the periphery. In that case, is the 1.4x rating is from the center of the frame (with the periphery magnification something less), or is the magnification rating an average over the entire frame?

Extenders impact AF performance.

"While it’s apparently less than was the case with EF-mount tele extenders and AF, there’s a designed-in reduction in actual AF drive speed of a lens with extenders mounted. This isn’t a design flaw, but rather a feature to ensure consistent AF, and ability for the AF drive to stop at the precise point of sharpest detected focus. Obviously, there’s also the issue of light loss with extenders, and while modern R-series cameras can technically AF at effective max apertures down to f/22, it’s clear that any modern AF system performs better with more light hitting the AF sensor, or image sensor in the case of mirrorless cameras." [Rudy Winston, Canon USA]

As a generalization, smaller pixels create a lower signal-to-noise ratio (SNR) and show more noise visible at a 100% resolution view. While that aspect does not distinguish between full-frame and APS-C imaging sensor sizes, APS-C imaging sensors often have higher pixel densities. This means that 100% view comparisons typically show full-frame models outperforming APS-C models.

Because of its larger size, a full-frame format (35mm) imaging sensor captures over a stop more light than an APS-C format sensor, with equivalent output size reflecting that difference in noise levels.

If cropping the full-frame image to the APS-C angle of view or narrower, the sensor size advantage evaporates, and in that case, f/4 is twice as wide as the f/5.6 max aperture of the 600 F4 + 1.4x combination.

Higher density imaging sensors show the effects of diffraction more readily, with slight effects beginning to show at about f/5.2 for the R7. However, those photographing long-distance subjects with long telephoto lenses likely want the widest aperture available, avoiding diffraction issues.

Should I get a higher pixel density camera or a longer focal length lens is a legitimate question. When getting to the long telephoto focal lengths, with reach as a goal, the camera option may be smaller, lighter, and less expensive.

A variation of that decision and the specific comparison investigated by this article is: should I get an EOS R7 or a 1.4x extender for a full-frame camera? Both options meet the same need.

When focal length limited with the highest resolution full-frame camera model, moving to a longer focal length lens with equal or better image quality is the ideal solution. However, such a lens is not always available, and it may be extremely expensive if it is — potentially far more costly than the R7.

In the case of the Canon RF 600mm F4 L IS USM Lens, Canon offers longer lenses, but with integrated 2x extenders, the Canon RF 800mm F5.6 L IS USM and Canon RF 1200mm F8 L IS USM Lenses do not have equivalent image quality and they are extremely expensive.

Let's take a look at a single APS-C vs. full-frame plus 1.4x comparison.

Note that I am testing the RF versions of the 600 F4 and 1.4x as they are what I currently have. The RF 600mm F4 and EF 600mm F4 III lenses have the same optics, and the RF 1.4x has only a slight optical advantage over the EF 1.4x III.

The images below were processed identically to the samples in the image quality test tool, with the low contrast neutral picture style and a very low sharpening value selected. However, the target was photographed at the same distance for both cameras and framed from farther than the standard framing distance.

Here is the R7 vs. R5 resolution comparison using the proper chart framing.

Numerous other camera combinations can be tested, but with the densest imaging sensor available, the R7 will rule all of them at this time, slightly besting the M6 II and the 90D.

Back to the promised test images:

The R7 image appears to have very slightly better resolution, and the R5 result's details are slightly larger, though I doubt these slight differences will be noticed in real-world images. The R5 image has more pixels and a modestly wider angle of view, but the R5 + 1.4x and the R7 have about the same reach.

When composed and cropped identically, the background blur created by 600mm f/4 should be similar to that of the 840mm f/5.6. At the same APS-C or wider angles of view, the R7 should take some high ISO noise advantage from the wider aperture enabling a lower ISO setting, and the R7 should avoid the (minor) AF performance penalty imparted by the extender.

Obtaining a sharp image requires all subject details to remain within the indivdual pixels capturing them during the entire exposure. In other words, motion blur is created by subject details crossing into adjacent pixels while the shutter is open. As imaging sensor pixel density increases, so does the shutter speed required to avoid camera and subject motion blur. The image brightness effect from increasing the shutter speed will often be offset by increasing the ISO setting, which increases noise.

However, increasing the focal length has the same effect. So in the end, the option with the most reach will have the highest shutter speed requirement.

Sometimes the camera settings required for a situation include a shutter speed sufficient for stopping motion at the lowest-noise ISO setting, making this point irrelevant.

Did you notice the diffraction softness showing in the R7 f/8 result vs. f/5.6?

Usually, a lens produces better image quality in the center of the image circle than in the periphery. APS-C imaging sensors utilize only the optimal center of the imaging circle. However, extenders magnify the center of the image circle, also utilizing the sweet spot. Thus, both options avoid the worst aberrations.

Here is a periphery comparison from the test described above:

These results tell a story similar to the first results.

Hopefully, the mix of information presented in this article was helpful. A conclusion from this discussion is that the Canon EOS R7 (or another high-density APS-C format camera) is a viable alternative to a 1.4x extender on a full-frame model when significant cropping (APS-C angle of view or smaller) will be required. That's just in case you needed an excuse to get this high-performance camera.

Sony Unlocks In-Camera Forgery-Proof Technology

Sony today announced the availability of its in-camera forgery proof photo technology for corporate business users. Using digital signatures processed at capture, Sony technology supports detection of any modification to an image, thus protecting it from fraudulent usage.

Following widespread issues with unauthorised editing and misconduct around digital photo data, Sony has developed forgery-proof technology, based on standard cryptography, for corporate users to safeguard images against future misuse.

With Sony’s in-camera signing mode activated, images are immediately cryptographically signed by the camera processor upon capture. Following this, any pixel modification, tampering or potential forgery will cancel the image signature, as the image manipulation will be detected by the customer’s own certificate server during examination.

Available on the Alpha 7 IV camera, with expansion to other models to be considered in sequence, this new functionality streamlines the lengthy process required from image submission through to verification, all with the addition of extra security.

The Alpha 7 IV also combines a 33.0MP full-frame back-illuminated Exmor R™ CMOS image sensor with BIONZ XR™ imaging engine to deliver high-speed processing and outstanding resolution.

Sony’s new forgery-proof signing mode ensures the secure creation and transmission of images based on cryptographic methods, as the fundamental need for certifying unmodified and secure images grows in many applications, across multiple industries.

This technology is particularly applicable for passports and ID verification but goes further in tackling image manipulation in the media, medical and law enforcement fields. For the insurance and construction sectors, this technology will offer a secure foundation for inspection and recording of damage.

Yasuo Baba, Director of Digital Imaging and European Product Marketing at Sony, commented: “It is Sony’s missions to strengthen business solutions with cutting-edge imagery technology and our in-camera digital signing is a real gamechanger for combatting image manipulation and forgery across multiple industries. Whilst appropriate adaptations for each industry need to be made, the digital signature is multilingual and can be used internationally, enabling organisations worldwide to streamline mandatory image signing with Sony technology.”

Currently compatible with the Alpha 7 IV, and subject to receipt of a license to enable Sony’s signing mode, this facility will be available for business users with plans for further model expansion to follow. In tandem, Sony will continue to examine how we can utilise our industry-leading imaging technology to further support enhanced security across multiple industries, with plans to expand the line-up of supported cameras hereafter.

85mm F1.4 AF Series II Full Frame Telephoto (Sony E)

The Rokinon AF SERIES II 85mm F1.4 for Sony E is the smallest (99.5mm/3.92in length) and lightest (509g/17.95oz weight) among all the large-aperture standard 85mm focal length lenses compatible with the Sony E mount.

The AF 85mm F1.4 E II (Large-Aperture Standard) lens delivers a 28.9° angle of view for full-frame & 19.1° for APS-C, as well as a bright maximum aperture of F1.4, as preferred by full-frame camera users. In particular, optimum resolution is achieved through the optical design of 11 elements in 8 groups (4 HR and 1 ED). Combined with Sony's full-frame image sensor, this lens delivers superior sharpness and contrast in all areas of the image.

Fast and Quiet AF Performance

Tracking the subject accurately and quickly, the AF also operates quietly and smoothly when shooting video. Rokinon’s Linear STM (Stepping Motor) satisfies both photographers and videographers with quieter and more accurate control of the focusing lens groups.

Impressive Background Blur and Bokeh with Bright F1.4 Aperture

The AF 85mm F1.4 E II uses a large-diameter aperture to provide smooth background blur. It effectively separates the subject from the background, using a shallow depth of field and adding drama to the scene. The 9 diaphragm blades create smooth and natural bokeh with light splitting.

Less Breathing for Shooting Video

The AF 85mm F1.4 E II has minimized focus breathing, so there is almost no change in the angle of view when focusing and therefore less screen shake. This is effective when shooting movies with the subject moving forward or backward, or focusing from the front or back.

Enhanced Usability with Custom Switch and Focus Hold Button

There is a custom switch, which can be set allow adjustment of the aperture by rotating the focus ring. Using the optional Lens Station, you can setup the mode to suit your own preference*.

* More functions will be added through firmware updates in the future

Customizable Focus-Hold Button Pressing and holding this button will keep the lens locked at the auto-focused distance. The user can also assign to the focus hold button other desired functions through the Custom Key Settings menu of the camera.

Short Minimum Focal Distance

The minimum focal distance is just 0.85m (2.79ft), so it is versatile and possible to produce a unique perspective close to the subject. This makes it easier to take close-up and dramatic shots of food, portraits and nature.

Weather-Sealing Design

The usability of the AF 85mm F1.4 E II lens has been developed and enhanced, taking into consideration not only the design but also the user's shooting environment. It has a micro-patterned rubber focus ring, so feels great to operate and weather-sealing also protects the lens from light rain, snow and dust.

New 50-400mm F/4.5-6.3 Di III VC VXD (Model A067)

July 27, 2022, Commack, NY - Tamron announces the development of the versatile 50-400mm F/4.5-6.3 Di III VC VXD (Model A067), a next level ultra-telephoto zoom lens for Sony E-mount full-frame mirrorless cameras. The lens is expected to be available Fall 2022. However, due to the current global health crisis, the release date or product supply schedule could change.

The 50-400mm F/4.5-6.3 Di III VC VXD (Model A067) creates an entirely new category for high-performance ultra-telephoto mirrorless zoom lenses. With an 8x zoom ratio that begins at an unprecedented 50mm (commonly called the “standard” focal length for full-frame cameras), this new ultra-telephoto zoom lens for Sony E-mount full-frame mirrorless cameras is the same size as conventional 100-400mm zoom lenses yet offers a wider angle of view on the wide end for exceptional versatility.

Equipped with TAMRON’s VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism that offers excellent quietness and responsiveness, plus TAMRON's proprietary image stabilization mechanism VC (Vibration Compensation), the lens delivers versatile capability for all shooting scenarios.

Since the 50-400mm provides up to one-half life-size magnification during close focus, users can enjoy the world of half-macro photography with excellent close-up shooting capabilities, with an MOD (Minimum Object Distance) of 9.8” at the 50mm end.

The filter size is Ø67mm, the same as most other TAMRON lenses for mirrorless cameras, providing greater convenience when using multiple lenses together. The lens also features ergonomic features that support comfortable shooting, such as the adoption of a new lens design with improved texture and operability, and a Connector Port for the dedicated TAMRON Lens UtilityTM originally and uniquely developed by TAMRON. In addition, for this 50-400mm F4.5-6.3, TAMRON Lens Utility newly offers a "Focus Limiter” function. An optional Arca-Swiss compatible accessory tripod mount is available for convenience when using a tripod.

The 50-400mm is a highly portable, versatile zoom lens that ensures users never miss a shooting opportunity, from the 50mm standard focal length up to the 400mm ultra-telephoto.
