Has anyone played or have this lens? I'm looking for a 35mm lens for my collection and this seems reasonably priced compared to lenses such as the MD 35mm f/1.8, which is difficult to find, or the FD 35mm f/2. I'm super interested in it's 1.4 max aperture and it's full metal construction. Is it worth the 349.99 USD Price tag though? I know that SLR Magic has their 35mm f/1.7 series that is much like the Fujican CCTV lenses, but that's kind of out of the question for me.
