What is the sony fe 40mm f 2 5 g good for?
The Sony FE 40mm f/2.5 G is a tiny, sharp prime for everyday shooting. On full frame it gives a near-standard view, a little tighter than the 50mm on the focal length guide, and it's easy to carry all day.
It suits street work well. A small lens at chest height draws less attention, as the street guide explains. At f/2.5 it won't blur backgrounds like a fast portrait lens, but it's fine for daylight and walking-around use. It isn't stabilised, so keep an eye on shutter speed in dim light.
It fits every full-frame Sony E body listed on its page, and on APS-C it behaves like a 60mm. Good pairings include:
- Sony a7C for a compact full-frame kit that matches the lens's size.
- Sony a7 III if you want a more capable all-rounder.
- Sony a6400 if you'd rather shoot APS-C.
