Summary: Excellent little lens. Feels very well constructed and the results with my Sony ILCE-7 (A7)are looking pretty amazing. The smallest focus distance is 0.7, with the new helicoid adapters it's suppose to go to a smaller distance of 0.2.
Summary: This is one of the best lens for the price! Been using it with my Sony A7R and the Fotodiox Leica M mount adapter! Sharp images at F1.4, no vignetting at all whatsoever! 40mm gives a little more focal length so when shooting full body portraits it doesn't give a weird wide angle/fisheye effect like...
Summary: THE SPECS: The solid metal build is nice. It's beautiful to look at. There is an impression of quality that comes from the lens' weight in your hands. The clickity clack of the aperture ring is pleasing. The focus ring is buttery smooth. An all around beautifully designed lens.
Summary: This is an excellent lens. I have been using it with an adaptor on the Sony A7. The Pros: -Small & Lightweight. -Beautifully built. -Focusing is smooth and has a small throw, which makes quick focusing easy. -Aperture ring feels solid, and has half stops. -Bright and Beautiful f/1.4.
Excerpt: Amazing little lens. Super small, light weight but very solid build. Looks and feels great on my Sony a7. Easy to operate, clicks are solid, focus is smooth but not loose (perfectly dampened). Overall very happy with this purchase.
Summary: IN MY LIFE LIKE US ALL, I MAKE MISTAKES. BUT THIS WAS NOT A MISTAKE, BUT A BOON AS IT IS DEMONSTRABLY ACCURATE AND SIMILAR TO ALEICA LENS AT TEN TIMES THE PRICE. I BOUGHT SUCH WITH A VOIGTLANDER BESSA R4A FOR THE COMBINED PRICE OF $1249 DOLLARS.
Summary: I have too many lenses. Zeiss, legacy Leitz, CV, and Russian. Many choices... and yet, this is the lens that usually winds up on my camera. I have the MC version, and filed down the flange (easy - instructions on the web, use a metal nail file) so that it brings up the 35mm frame lines on my M9.
