I have recently had the honour to acquire this lens from a photographer who had used it. I now use it on the Sony A7 series (both A7r and A7II). I absolutely love this lens. The focusing is a bit tough as it has a razor thin DOF...but if you can manage it, the images are outstanding in its dreamy appearance. rnrnThe build quality is superb and its an all metal body. So its definitely a tad heavier than most 50mm lenses available in the market. Those searching for a sharp lens from edge-to-edge may find it disappointing. But those who consider Photography as an art form, and consider a picture as a painting of light will find delight with this masterpiece. rnrnThe lens comes in two versions a TV version and a non-TV version. I own the TV version, and have heard from other fellow photographers that this is the better version to own. rnrnVisit here for a sample image- https://instagram.com/p/2afb5rHtoK/
