Sony α7CR / FE 50mm F2.5 G — 50mm f/2.5

Pre-computed optical tables for Sony α7CR (61MP) with FE 50mm F2.5 G at 3m: Near limit 2.60 m, Far limit 3.55 m, Total DoF 0.95 m, Hyperfocal distance 33.33 m, and 39.3° Horizontal FoV.

Optical Formulas

Hyperfocal Distance H = f² / (N × c) + f
Near Focus Limit D_near = s(H − f) / (H + s − 2f)
Far Focus Limit D_far = s(H − f) / (H − s)
Angle of View AoV = 2 × arctan(d / 2f)

Frequently Asked Questions

What is the Depth of Field and Hyperfocal Distance for Sony α7CR at 50mm f/2.5?

At 3.00m focus distance, the Sony α7CR at 50mm f/2.5 produces an in-focus zone from 2.60 m to 3.55 m with a hyperfocal distance of 33.33 m.

How is Hyperfocal Distance calculated in photography?

Hyperfocal distance is calculated as H = f² / (N × c) + f, where f is focal length in millimeters, N is the aperture f-number, and c is the Circle of Confusion diameter in millimeters. Focusing at H keeps everything from H/2 to infinity acceptably sharp.

Why does sensor size affect Depth of Field and Equivalence?

To match the same Angle of View on a smaller sensor, you use a shorter focal length. Multiplying both focal length and f-stop by the sensor crop factor yields the 35mm equivalent focal length and equivalent aperture for Depth of Field.

How do Front and Rear Depth of Field split across distances?

At close portrait distances, Depth of Field splits nearly evenly around the focus plane. As focus distance approaches the hyperfocal distance, rear Depth of Field expands rapidly until reaching infinity.

What DPI is needed for gallery fine-art printing?

Museum and close-inspection prints target 240 to 300 DPI. Large wall prints viewed from 1.5 meters or more remain crisp at 150 to 180 DPI.
