Sony fe 50mm f 2 5 g vs sony fe 50mm f 2 8 macro?
Both are 50mm autofocus primes for Sony E full frame, and neither is stabilised. They differ mainly in what they're built for.
The Sony FE 50mm f/2.5 G is the general-purpose pick. Its f/2.5 lets in a little more light than the macro's f/2.8, so it's the one I'd reach for for everyday shooting.
The Sony FE 50mm f/2.8 Macro makes more sense if close-up work is your main interest, such as flowers, small objects or fine detail. Its f/2.8 is a touch slower, so it gives slightly less background blur in the same framing.
If you mostly photograph people, the portraits page explains why a 50mm suits them, and the f/2.5 G is the better fit.
