Sony A7RV Review: A Fantastic Hybrid Camera with a Few Quirks
The Sony A7RV is a powerful full-frame mirrorless camera that excels in both photography and videography. It boasts impressive features like a 61-megapixel sensor, advanced AI-powered autofocus, and 8K video recording. However, like any camera, it has its pros and cons. Let's take a closer look at what makes the Sony A7RV tick.
Pros
● Image Quality: The A7RV uses the same 61-megapixel sensor as its predecessor, the A7R IV, which delivers exceptional image quality with expansive dynamic range. It also boasts a new processor, the same one found in the flagship Alpha 1, which is eight times faster than the A7R IV's processor and results in slightly better color and noise performance at higher ISOs.
● Autofocus: This camera features a dedicated AI processor for autofocus, making it one of the most advanced autofocus systems available. It can track a wide range of subjects, including humans, animals, birds, insects, cars, and even planes. The autofocus can recognize human poses, identify body parts, and even predict movement. It is also incredibly sticky, even in challenging situations like sports photography.
● Video Capabilities: The A7RV can record 8K video at 24 frames per second and 4K video up to 60 frames per second. It also offers oversampled 4K recording in APS-C crop mode at 24 and 30 frames per second. The camera supports 10-bit color depth across all video modes and includes professional features like S-Cinetone, focus breathing compensation, and a focus map.
● Screen and EVF: The A7RV sports a new tilt/flip screen mechanism that combines a tilting layer with a fully articulating one. This design provides excellent flexibility for framing shots from various angles and is considered by some reviewers to be the best screen mechanism available. The electronic viewfinder (EVF) is also excellent, with a high resolution of 9.4 million dots and a refresh rate of 120fps.
● Stabilization: Sony claims up to 8 stops of image stabilization with the in-body image stabilization (IBIS) system. This stabilization proves especially effective in telephoto handheld shots, where it can deliver rock-solid footage.
Cons
● Rolling Shutter: One of the main drawbacks of the A7RV is its rolling shutter performance, particularly noticeable in 8K and oversampled APS-C modes. This is due to the sensor's relatively slow readout speed, which is inherent to high-resolution sensors. While the binned full-frame 4K mode offers better rolling shutter performance, it's still not as good as some competing cameras.
● Cropping and Binning: The various video recording modes involve a complex combination of cropping, binning, and oversampling, which can make it difficult to determine the true focal length while shooting. This complexity can be a bit cumbersome for videographers who need to quickly switch between different recording settings.
● 8K Limitations: While the camera can record 8K video, it comes with several limitations. The 8K mode has a significant crop factor, and active stabilization is not available in this mode. Additionally, the 8K recording mode generates a lot of heat, which can lead to overheating issues.
● Dust on Sensor: Despite Sony's updated ultrasonic sensor cleaning system, the A7RV still seems susceptible to dust accumulation on the sensor. This can be a significant issue for photographers who frequently shoot landscapes or architecture, where dust spots are more noticeable.
Conclusion
The Sony A7RV is a powerful hybrid camera that offers exceptional image quality, advanced autofocus, and robust video capabilities. Its AI-powered autofocus system is a game-changer, making it easier than ever to track and capture moving subjects. The new tilt/flip screen mechanism is also a welcome addition, providing greater flexibility for framing shots.
However, the camera's rolling shutter performance, complex video recording modes, and susceptibility to dust on the sensor are notable drawbacks.
Overall, the Sony A7RV is a compelling option for photographers and videographers who demand high resolution and advanced features. However, those who prioritize fast action photography or need the absolute best video performance might want to consider other options, like the Sony A1.
