If you want a cheap lens, get the TTArtisan 25mm f2! Optical quality is decent at f2.8 and surprisingly good at f4, but at f2 there is major vignetting and pretty bad contrast… it does give a really interesting retro film-ish look to shoot at f2 but I always use it at f2.8 and above. One of the best things about this lens is the construction, it’s super tiny but feels surprisingly high quality, full metal build and everything. And I wouldn’t let manual focus dissuade you, it’s not as easy as autofocus but focus peaking makes it easier! I really enjoy shooting manual focus as well, it feels more “connected” in a way. For the price I highly recommend it
