Quick verdict
Canon R6 II
Sony A7 IV
Canon R6 II scores higher with a 4.5/5 average across professional reviews from 2 sources.
The Canon EOS R6 Mark II is a significant upgrade that resolves the original model's video limitations by offering uncropped 4K/60p recording and vastly improved thermal management. It introduces specialized autofocus capabilities for vehicles and animals, making it a versatile tool for both enthusiast photographers and hybrid shooters. While it lacks the flagship's eye-control feature, its refined handling and expanded burst speeds make it a compelling choice for dynamic shooting scenarios.
Strengths
- +Captures oversampled 4K/60p video using the full sensor width without the crop found on the predecessor
- +New 'vehicle' subject tracking mode specifically optimized for motorsports, cars, and aircraft
- +Improved thermal performance allows for extended recording times, with tests showing over an hour of 4K/60p capture
- +Electronic shutter burst rate increased to 40fps with pre-capture RAW burst functionality
- +Enhanced autofocus includes dedicated horse and zebra detection with eye and head tracking
Watch-outs
- −Lacks the eye-controlled autofocus system found in the flagship EOS R3
- −Full HD slow-motion footage at 180fps is not oversampled, resulting in lower quality compared to 4K modes
The Sony A7 IV is a highly capable hybrid camera that successfully bridges the gap between high-resolution photography and professional video production. Its standout features include a significantly upgraded autofocus system with reliable subject tracking and a versatile 33MP sensor, though users should be aware of the trade-offs between burst speed and image quality in Raw mode. While the price is higher than its predecessor, the comprehensive feature set makes it a compelling upgrade for enthusiasts and professionals alike.
Strengths
- +Significant autofocus improvements including seamless switching between human, animal, and bird eye detection for both stills and video.
- +New 33MP BSI-CMOS sensor provides higher resolution and detail compared to the previous 24MP model while maintaining 10fps burst shooting.
- +Enhanced video capabilities featuring full-width oversampled 4K from 7K, 4K/60p in APS-C mode, and a dedicated movie mode switch.
- +In-body stabilization rated up to 5.5 stops and a high-resolution 3.69M dot OLED viewfinder improve handling and composition.
- +Practical dual card slot configuration supporting CFexpress Type A and UHS-II SD cards for professional workflow flexibility.
Watch-outs
- −Shooting uncompressed Raw at 10fps requires lossy compression which damages image quality, while lossless compression drops the speed to 6fps.
- −Silent shutter mode causes significant rolling shutter distortion on moving subjects due to a slow 1/15 second full-sensor readout time.
- −The camera's price increased by $500 compared to the launch price of the a7 III, raising the entry cost for this generation.
