>>4301400The sigma 18-50 f2.8 is well regarded and small. I have the 18-135 and it’s pretty good all around. A little slow but sharp when stopped down and the range is really useful. 18-135 +Rokinon 12mm f2 makes a good hiking/backpacking kit if you’re into that.
I have an a6400 as well and the 35mm f1.8 was my first prime lens. It’s fine…but I’d probably get the sigma 30 instead. The Sony isn’t really sharp until around f2.8-4, has some color fringing wide open. It’s decent but not a good value new. It is compact and sharp stopped down and the OSS is handy, especially for video.
One of my favorites right now is the Tamron 24mm f2.8. It’s a full frame lens that’s pretty sharp wide open, close focusing and 1:2 macro. It’s not too big either. It’s somewhat slow and loud when focusing and unstabilized. But it’s really a good value. They make a 35mm as well if you’re really set on 50mm-ish field of view.
I like my a6400 pretty well. I just wish it had a more comfortable grip (I have big hands) and maybe a few more megapixels.
