Yeah that 135L is a top of the line lens and the 35/1.4 isn't a slouch either. Nobody uses these on film because they're all digital freaks. Be the first, or third ;-).

Personally my 135L doesn't get a lot of use primarily because I don't use that length a lot but when I have the results have been stellar. I do have some 85/1.2L film shots on my Flickr but that was a rental. I prefer manual focus lenses in general.
