Chris tested the four High Res cameras from each company. That’s what he thinks about them:
1. Panasonic Lumix S1R II (44 Megapixels)
- 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.
2. Sony a7R VI (66 Megapixels)
- 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.
3. Canon EOS R5 Mark II(45 Megapixels)
- 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.
4. Nikon Z8(45 Megapixels)
- 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.
In short, the Sony a7R VI stands out as the best for outright image quality, the Nikon Z8 is the best for speed-oriented action, and the Canon R5 Mark II is the best all-around camera that does everything in a single package.
