Prime lens

A prime lens by Tokina for APS-C cameras, 56mm f/1.4.

What it frames like

Its full-frame-equivalent focal length on the sensor it was made for.

How wide 56mm sees on each sensor it covers.

f/1.4 wide open, to scale against f/1.4.

On APS-C (Sony E, Fujifilm X): like 84mm on full frame; f/1.4 gives about the depth of field of f/2.1 there.
On the larger-sensor bodies of Sony E: it works with the camera in a APS-C crop mode, at fewer megapixels.
