TTArtisan APS-C 25mm F2 Lens (Black, x Mount)

This has been my favorite of the ultra-cheap lenses for APS-C. It's not going to perform like a big name lens, but it's got a lot of charm. The only thing to look out for is the need to calibrate: the focus ring overshoots infinity on many copies, but it is fairly easy to adjust using 3 screws on the focus ring (and a little trial and error)

I bought this lens appealed by its size and the cost. Moreover, I wanted to try this focal lens before engaging a more significant purchase (e.g. fujinon XF 23 f2 or f1.4).I tried in 2 different occasions, And these are my considerations:The image quality is acceptable for the prize, and with the right configurations can even be quite good (i.e. with higher aperture values, about 5.6 or 8). It's not easy to get the right focus for subjects that are quite far, but it could depend also on my version.It suffers flare a lot up to f 4.I suggest it as a fun lens that make your camera pocketable and with a kind of vintage look, but not very reliable.I attach some photos (jpeg straight out of camera, Provia film simulation).B&H service was perfect.

I've been shifting to using manual focus lenses to allow me to better control degree of sharpness, and this lens covers all the bases (and can be quite sharp when I want it to be). It works great with an IR converted camera as well.
