Sony A7R IV
Sony FE 50mm f/1.2 GM

Examples: Old Talc Mine

This page shows some initial examples with the Sony FE 50mm f/1.2 GM, shot in dull lighting at an old talc mine near Death Valley. The images were shot with an eye to showing how the 50/1.2 GM can pick out exactly the desired subject matter from its surroundings.

Shot handheld with IBIS and mostly using spot autofocus, sometimes in conjunction with magnified Live View for precise focus placement.

Includes images up to full camera resolution. Most images used vignetting correction.


Razor thin depth of field at f/1.2 at this range, but following the 'cut' through metal and wood, it’s clear that this is one very sharp lens. Indeed, depth of field is so thin that it’s difficult to make clear statements about micro contrast, except for the shots at distance.
