Sony sonnar t e 24mm f 1 8 za vs meike 25mm f 1 7 air?
Both are fast APS-C primes with autofocus and no stabilisation, so the choice comes down to mount and a small difference in framing.
The Sony Sonnar T\* E 24mm f/1.8 ZA frames like 36mm on full frame and gives about the background blur of f/2.7. It only fits Sony E.
The Meike 25mm f/1.7 Air frames like 38mm and is a touch faster, with blur close to f/2.5. It fits Sony E, Fujifilm X and Nikon Z.
My pick: if you might ever switch systems, get the Meike, since it works on three mounts and is slightly brighter. If you're settled on Sony and like the wider 24mm view, the Sonnar is the one. For more on how primes compare with zooms, see Lenses.
