Hi all. A quick question, while I'm musing on the subject. I've indicated in the past that I'd like a pancake lens. My D700 is never going to be all that portable, but not having even a 50mm f/1.8 sticking out the front of it might be the difference between a coat pocket and leaving it behind. I'm quite tempted by a 45mm f/2.8 AI-p, but they're probably more money than they're currently worth to me. It recently came to my attention that the series E 50mm f/1.8 lenses seem to be appreciably shorter than the AF version - I've always thought that the AF lens's design of having the front element so inset was harming the ergonomics for me, and the series E seems to solve that. While it's not as short as the 45mm, and I have to treat it as an AI lens (which is fine - I'm often in aperture priority or manual anyway and I've got on okay with a 135mm f/2.8 AI), one could argue that the optics are better, at least in terms of sharpness, than the official pancake - although I appreciate the bokeh suffers. It's a shame it won't meter on a lightweight camera like an F75, should I get one, but I can live with that. I would expect behaviour very similar to the f/1.8 AF-D (lousy bokeh, not very good wide open, very sharp stopped down) since I gather the optics are almost identical. At some point I may get a 50mm f/1.8 AF-S for its optical advances, but I accept the size compromises when I do so. I expect maybe a little more ghosting and less contrast from the E-series, if its coatings aren't up to snuff, but I'd hope this would be a minor issue. So, for a cheap alternative to the 45mm Ai-P, am I mad to consider one? Cheers for any thoughts.
