Sony distagon t fe 35mm f 1 4 za vs sony fe 35mm f 1 4 gm?
On paper, these two lenses are the same. Both are 35mm f/1.4 primes for full frame Sony E cameras, both autofocus, and neither is stabilised. Both frame the same on APS-C bodies (like 52mm, with depth of field around f/2.1), and they list the same camera compatibility, so either will work on any body in the list on each page: Sony Distagon T* FE 35mm f/1.4 ZA and Sony FE 35mm f/1.4 GM.
The site doesn't cover their price, optical differences, size, or weight, so I can't tell you which one is sharper or better built. Those are the things to check in reviews before you buy. If one is much cheaper, especially used, that's a good reason to pick it. Check buying used first, and make sure the seller's body is in the compatibility list.
