fast the one technical thing i've noticed is when i shoot it wide open especially with a 1.4 adapter on i get a lot of vignetting at certain times a day and actually it's a pretty beautiful look the vignette look but i'd rather not have to correct it on some images and put it in post-processing…

You can see there's a beam of light coming through on the left hand side, hence why her left eye is brightened up.
