Digital Camera World Verdict

While I have always thought the 90mm focal length was the oddball of lenses, this 50mm sinic absolutely fell in love with this lens. Its clinical Leica APO characteristics and great balance in the hand make this the perfect lens to always have on your camera and to always get the shots you have in mind. Its construction is beyond anything thing else on the market, and while its maximum aperture is "only" f/2 it produces some beautiful images shot wide-open, and if stepping down between f/5 to f/8 you will have razor-sharp images that anyone can be proud to display or show off, in all I'd say if you don't have a 90mm in your collection... you might just be missing out on a gem!

The Leica 90mm APO Summicron-SL f/2 ASPH, and the whole 90mm focal length, in general, I have always seen as an oddball of all focal lengths - not wide enough to be useful and not telephoto enough to get the best reach - How wrong I was!
