I'm enjoying my E-P1 so much that I'm going to push the boat out and treat her to a fine lens and have narrowed things down to these two. I am happy with manual focusing (in some ways I prefer it) but there are times that AF would be very nice. Has anyone used both of these lenses? Any comparative shots? Has anyone used the PL45 on an E-P1? Was the focus okay? For me it comes down to autofocus vs DoF control. Plus the feel of the images. I do like the Sonnar "look". What do you think? (Btw, I'd be buying the Sonnar on Leica M mount as I already have a Metabones M adaptor. I'd be selling my Contax CZ Planar 50mm f1.4 C/Y mount to part fund it. I prefer the balance of the smaller M-mount lens on the E-P1 and prefer the "look" of Sonnar to the Planar.) Many thanks for your thoughts.
