Is the ttartisan 50mm f 2 good for portraits?
The TTArtisan 50mm f/2 can work for portraits, with one caveat: it's manual focus only. That's fine for posed portraits, where you have time to focus carefully, but harder for kids, pets, or anyone who won't stay still.
On full frame it gives a natural, slightly tight view, which suits head-and-shoulders work. On APS-C it frames like about 75mm, which is a classic portrait length. The portraits guide puts a 50mm f/1.8 at the top of its list because it's the cheapest great portrait lens, and this one is in the same focal range. If you can afford it, that autofocus lens is the safer buy for working people. Either way, the lens page lists which cameras it fits.
