SG-Image AF 35mm f/2.2: 163g Budget Prime for Sony/Nikon FF

If you've been hunting for a pocketable 35mm that won't wreck your wrist on all-day street shoots, this ultracompact from SG-Image is worth a look — at 163g it undercuts most budget primes on size, and the all-metal build at least sounds like it punches above its AliExpress price point. Real question is whether the AF is fast enough to actually trust in the moment.
