Viltrox af 25mm f 1 7 air vs meike 25mm f 1 7 air?
On paper these two are twins. Both are 25mm f/1.7 primes for APS-C, both have autofocus, neither is stabilised, and both fit Sony E, Fujifilm X and Nikon Z with the same list of bodies. On APS-C they frame like 38mm on full frame and give about the depth of field of f/2.5.
The one difference I can point to is how I describe them. I call the Viltrox AF 25mm f/1.7 Air a cheap, light standard prime. I don't have price or build comparisons for the Meike 25mm f/1.7 Air, so check current prices and reviews before you buy.
In practice, choose whichever is cheaper where you live, as long as your body appears in its camera list. Also check that your camera maker allows third-party lenses on your mount, as explained in third-party lenses.
