ok, yeah, almost certainly designed for aps-c... vignetting, chromatic distortion, angular distortion, the works
like, from a technical perspective, it's an absolutely ass lens
from an artistic one, well, you'll see here in a bit, still gotta bring everything through the pipeline :3
i like it, a lot. turns this fancy mirrorless camera into a disposable point and shoot... that still takes 38MiB raws ^^'
it'll be replacing the body cap, like as a bonus lens, will probably still use the kit or super-takumar in the day to day though
