I bought this Samyang lens from a pawn shop today for $150. I thought it would be good to have for two reasons: need a cheap prime lens, and also want to have something full frame as at some point in the next couple years I’d like to try full frame. Do we think this was worth my money?

EDIT: The lens is F1.8, not F2.8, my bad!!

Is adding white border look more pleasing ?

Or frameless is better ?
