Sony Alpha a7R VI Review: Stacked Sensor Resolution Without Compromise: Strengths & Caveats
✔ Advantages
- 66.8 MP stacked Exmor RS sensor delivers rapid readout speeds virtually eliminating rolling shutter while enabling 30 fps continuous shooting
- Upgraded 5-axis IBIS provides up to 8.5 stops of stabilization compensation for handheld shooting in low light
- Class-leading 9.44M-dot Quad-XGA OLED EVF with 120 Hz refresh rate and 0.90x magnification
- Rugged magnesium alloy construction with extensive weather sealing and dual CFexpress Type A / SD UHS-II slots
✖ Documented Caveats
- CFexpress Type A cards command a significant price premium per gigabyte compared to Type B alternatives
- Extended high-bitrate 8K 30p capture generates noticeable localized heat on the rear magnesium housing
Sony a6700 Review: Brilliant Autofocus Marred By Heavy Crops: Strengths & Caveats
✔ Advantages
- 26.0 MP back-illuminated Exmor R CMOS sensor coupled with BIONZ XR and dedicated AI Processing Unit
- Advanced Real-time Recognition autofocus tracking across humans, animals, birds, insects, and vehicles
- Integrated 5-axis in-body image stabilization rated for up to 5.0 stops of compensation
- High frame rate 10-bit 4:2:2 video capture up to 4K 120p and FHD 240p with S-Cinetone and S-Log3
✖ Documented Caveats
- Significant 1.58x field-of-view crop during 4K 120p video recording
- Single SD card slot provides no secondary redundant backup for critical shoots
- Omits a physical rear autofocus joystick, relying on touch navigation or control dials
