...and can't have. Call it a perfect lens. Of course there is no such thing as a perfect lens. Why do I want it? Mostly because I like keeping things simple and working with what I have. The perfect lens however would be a whole lot less work. BUT...I have yet to find one. I have a few that come close and my definition of "perfect" changes from time to time. There are however a few qualities that keep popping up. - I like that 40mm EFL so 28mm lenses tend to get my attention. - I love to get close so a lens that does close focus is always a good thing. - I like lenses to be at least f2.8 (faster is good) - I like smallish lenses because they fit on the NEX body better. Over the years I have had quite a few lenses that came close. None of them did everything I wanted but some have come close. The OM 28/3.5 was an absolutely terrific lens. It was tiny, sharp and you could get remarkably close with it. I liked it better than the OM 24/2.8 and at $30 it was an absolute steal. Constrictor by kevin dixey, on Flickr My Komine made Vivitar 28/2 Close Focus was the reigning champ for about 4 years...but the super long throw focus made it a pain to use when I switched to using a Fuji (no flip down screen) and it hasn't made the starting lineup since. Mister Pissy by kevin dixey, on Flickr That Damp Snake by kevin dixey, on Flickr I had an MC Rokkor 24/2.8 for a while that was wonderful. It was also as heavy as a cannon ball. Son, Tho Art Silly by kevin dixey, on Flickr I replaced it with an MD 24/2.8 (sharper AND lighter) and I like it but the 36mm ELF is just a bit wide for my tastes. old neighborhood by kevin dixey, on Flickr The current king of the hill is my Nikon 28/2 AiS. I had originally set out to pick up the much loved 28/2.8 AiS but I stumbled on the 28/2 at the local camera store and got it for a great price. painterly by kevin dixey, on Flickr penta by kevin dixey, on Flickr It's a terrific lens but it is pretty huge. So far the reigning champ has no challengers but based on the past few years that could change. I think the Vivitar might be looking for a rematch.
