Got a new camera lens for cheap, but it's a bit temperamental. Sometimes stops working and the camera spits out an error, when starts working once again. Very likely due to the fact it's 3rd party and wasn't really meant to be adapted to a mirrorless camera.
I did debate on returning it, but other than that issue (which doesn't happen THAT often) it is excellent. I can't really afford anything better at the moment!
My dream lens is very similar, but it's a stop faster and it costs... £3000, easily 10x more than what I paid for this. So yeah, it will do for now.
