Optics and Lens Considerations

The CMOSIS CHR70M sensor is slightly smaller than the standard 35mm format.

The

CHR70M has a diagonal of 38mm vs the 43.3mm diagonal of the 35mm format. This results in an in-
crease in effective focal length of 43.3/38 = 1.14X.

Thus:

a 50mm focal length lens for a 35mm camera will have an effective 57mm focal length.

Full Frame 35mm format sensor (36x24mm)

CHR70M sensor (31x22mm)

The CMOSIS CHR70M sensor pixel size is quite small for a large sensor at 3.1um pitch. This

presents a challenge for the selection of a lens. Some of the best lens we have tested are these from
