Chris tested the four High Res cameras from each company. That’s what he thinks about them:

• At base ISO, this model resolved slightly less detail than the other cameras, though the difference is very minor.
• At higher ISOs (above 5000), it applies aggressive baked-in noise reduction to the RAW files, resulting in cleaner images but a noticeable loss of fine detail.
• It has the slowest readout speed of the group at around 37ms, which can result in more rolling shutter distortion when using the electronic shutter.
• However, its in-camera high-resolution multi-shot mode is a notable feature that works effectively when shooting on a tripod.

• Thanks to its higher resolution, it offers a noticeable improvement in overall detail, making it highly effective for heavy cropping or large-scale printing.
• It showed strong dynamic range and high-ISO performance, which is attributed to image-stacking technology and the noise advantages of having more pixels at equivalent viewing distances.
• Its readout speed has improved significantly over previous generations to around 19–20ms, though some rolling shutter can still be observed in fast-action scenarios.

• Its overall sharpness and detail are comparable with the Nikon Z8.
• While it uses baked-in noise reduction in its RAW files, this sensor handles it well, preserving detail while keeping images clean at higher ISOs.
• Equipped with a stacked sensor, it boasts a very fast readout speed of around 6 to 6.5ms, making rolling shutter virtually non-existent and making the electronic shutter highly practical for high-speed action.

• Like the Canon, it delivers strong sharpness and detail, but produces slightly cleaner shadow details and smoother blacks when shooting at high ISOs.
• Featuring a fast readout speed of under 4ms, it allows users to shoot fast action and sports using the electronic-only shutter without worrying about rolling shutter distortion.
• The sensor’s balance of speed, dynamic range, and clean image quality remains a solid asset for shooters.

So who wins?

• For Raw Sensor Performance (Detail, Dynamic Range, and ISO): The Sony a7R VI is the clear top performer. It is favored for its high 66-megapixel resolution, which provides unmatched cropping flexibility, and its class-leading dynamic range (greatly aided by its dual-exposure image stacking).
• For Speed, Wildlife, and Action: The Nikon Z8 takes the crown. Its sensor scanning speed of under 4ms is so fast that it completely eliminates the need for a mechanical shutter, allowing you to capture high-speed action with zero rolling shutter issues.
• For the Best All-in-One Hybrid Package: The Canon EOS R5 Mark II is highly praised as the most versatile option. It beautifully splits the difference by combining excellent 45-megapixel detail, strong high-ISO noise control, and a fast 6ms stacked sensor that enables incredibly high burst rates with minimal rolling shutter.

Meike has officially announced the development of the AF 85mm F1.2 lens—a full-frame, autofocus prime lens featuring a fast F1.2 aperture. It will utilize Meike’s latest proprietary technology, prioritizing weight reduction while maintaining high optical quality; the optical design is already largely complete, with the lens body weight kept under 900g. Two development paths are currently being explored:

1. Engineering plastic version: 750g–780g
2. Metal version: 870g–900g.

Which version do you prefer?

DZOFILM has announced the launch of the Octopus II Adapter and Marlin 1.4x Extender, providing with greater flexibility, compatibility, and efficiency across a wide range of filmmaking applications, from short-form bloggers, content creators, livestreamers and YouTubers to independent filmmakers, commercial media and advertising, and professional DOPs.

Octopus II: 2nd Generation Multi-Mount Lens Adapter
The new Octopus II is a highly versatile multi-mount lens adapter that supports E, Z, L, and RF mount lenses, as well as Super35, full-frame, and medium-format sensors. With 7.12% more internal space, it offers improved compatibility with DZOFILM’s Arles, Arcana, Vespid, Catta, Pictor, Gnosis, and other professional cinema lenses.

The second-generation design is up to 49% lighter, weighing as little as 190g (depending on mount). Its strong aluminum body is paired with a stainless-steel mount that is rated for more than 100,000 mounting cycles with 0.01mm precision, ensuring long-term reliability and durability.

The redesigned ergonomic handle features directional guides that make lens changes easier, particularly when working with handheld or fully rigged camera setups. A detachable 1/4″ threaded base allows the center of gravity to be shifted onto the adapter, reducing stress on the camera’s native mount. In addition, the factory pre-set flange focal distance eliminates the need for calibration while ensuring accurate infinity focus.

Marlin 1.4x Extender with Integrated Back-Focus Adjustment
The new Marlin 1.4x Extender increases effective focal length by 1.4x while maintaining light loss below one stop, enabling lenses designed for Super35 to cover full-frame sensors.

The extender incorporates premium high-refractive-index SR optical elements, large-diameter aspherical lenses, and an internally flocked design that effectively minimizes stray light. Chromatic aberration is tightly controlled, helping preserve the original character of the lens. Integrated back-focus adjustment eliminates the need for operators to detach the lens or use shims during setup and fine-tuning.

Manufactured with stainless-steel mounts on both sides, the Marlin 1.4x Extender is engineered for long-term reliability and durability. Precision machining further helps prevent binding during mounting and operation.

The new lens is now on preorder at BHphoto, Amazon, BrightinStar.

In this video, photographer Matt Granger conducts a shootout between five professional 70-200mm f/2.8 lenses from top manufacturers. Tested on their respective high-resolution camera bodies in Hong Kong, the lenses are evaluated on handling, build quality, autofocus performance, image stabilization, and overall image quality.

The Five Contenders

Canon RF 70-200mm f/2.8L IS USM Z (tested on Canon R5 Mark II)
Nikon NIKKOR Z 70-200mm f/2.8 VR S II (tested on Nikon Z8)
Sony FE 70-200mm F2.8 GM OSS II (tested on Sony A7R V)
Sigma 70-200mm f/2.8 DG DN OS Sports (tested on Leica SL3)
Leica Vario-Elmarit-SL 70-200mm f/2.8 ASPH(tested on Leica SL3)

Matt concludes that if you are using a Sony, Nikon, or Canon system, their respective 70-200mm lenses are absolute top-tier choices that will not disappoint. The Sony takes a slight edge for its incredibly lightweight and ergonomic design.
Conversely, the Leica acts more like a luxury item—it looks and feels premium but is too heavy and slow for demanding professional workflows. The Sigma, while optically sound, struggled massively with autofocus tracking, making it hard to recommend in this highly competitive class.
