I have been interested in using my lenses from my Kodak Retina Reflex on my Nikon for a long time. I have had trouble finding recent comments or photos and was having second thoughts about getting an adapter after reading comments. I finally decided to buy the Fotodiox adapter. I went out recently and took a few photos with the adapter using the 35mm f2.8 Retina-Curtagon and the 50mm f2.8 Retina-Xenar. I had read about mounting issues with the adapters, and found that the lenses were difficult to get mounted. It took a little more force than I was expecting, but the lenses mount. I was using my Nikon Df and found it difficult to manual focus using the viewfinder. Using live view was a little easier. I am happy with the results so far. It is a slow process, but the photos turned out better than I hoped. I knew the lenses were good performers, having used them on my Retina reflex S, but was wondering how they would perform with the adapter on a modern digital slr. I just wanted to do this post in case there are others who may be interested in using an adapter.
