About the Sony A7R V
The Sony A7R V is Sony's 61MP high-resolution full-frame mirrorless. The A7R V's 61MP BSI CMOS sensor demands precise focus accuracy — at f/2.8 with a 100mm lens, the focus plane is extremely thin. DOF planning is especially critical at this resolution.

Depth of Field on the Sony A7R V
The Sony A7R V's Full Frame sensor with a circle of confusion of 0.029mm means its DOF characteristics differ from other camera systems. The A7R V's 61MP BSI CMOS sensor demands precise focus accuracy — at f/2.8 with a 100mm lens, the focus plane is extremely thin. DOF planning is especially critical at this resolution.
Key DOF Concepts for Sony A7R V Shooters
- Hyperfocal distance: Focus at this distance and everything from half that distance to infinity will be sharp — useful for landscapes and street photography.
- Wider aperture (lower f-number) = shallower DOF — portrait shooters often use f/1.4–f/2.8 to isolate subjects.
- Longer focal length = shallower DOF at the same subject distance and aperture.
- Closer subject = shallower DOF — at macro distances, DOF can be a fraction of a millimeter.
