This one has been in my collection of classic 50's for a couple of years and is a favorite. While it doesn't capture the same level of attention as some of the other more renown 50's, it's still a ton of fun to use. The build quality is beyond reproach, nothing buy metal and glass, the thing just feels solid. Wide open, there is a glow due to low contrast and resolution or some other aberrations I'm not really qualified to talk about - this definitely gives the photos a vintage look to them. Stop the lens down a bit and image will become sharp and contrasty enough for most - actually kind of fun to have this much variability in a lens. Colors are fantastic and saturated, but the lens does B&W quite well too. Bokeh is of the bubble variety and can be distracting at times if there is a busy out-of-focus background (like a bunch of trees) when you are focusing on something at mid or longer distance. For closer distances, the bokeh is quite buttery particularly when using a close-focus adaptor or extension tube. If you're looking at getting into these old manual lenses and want that fast aperture this one won't disappoint, at around $350 for a good copy, this might be your ticket. I have several Flickr albums dedicated to Canon's old lenses - here is the location for this beauty!
