The CA and purple flaring and double lining in bokeh are turning me away from the Canon 50 F/1.4 , I generally shoot at F/2.0 and the results are decent on FF, ideally I want to shoot at F/2.8 as it's sharp all around with minial CA and still shallow enough, but highlights are not circular, and in general the bokeh of the lens could be a lot better. And crazy triangle highlights in corners at 1.8 ~ 2.8 or so, they really tear up the image sometimes. And besides, aside from weight and cost, shooting a normal prime at F/2.8 so often tells me to just go and get a zoom lens. I'll keep the lens for 'product shots' or anything that needs the fantastic sharpness from F/4.0 though, it's a good length for the sort of stuff I like too. However, the lens was best on crop, although somewhat long, the overall performance wasn't as bad there.
Now I'm looking at the Sig 35mm, turns out something wider for scenes and portraits are what I was after too~
