Review on Fotodiox Pro Fusion Adapter Smart by Josh Sharp

If you're considering buying this adapter, consider the Sigma MC-21 again. I bought this item on recommendation because it fits better (which it does) and everything has worked fine for a while (I have a Panasonic S1H). Then I suddenly had problems with my Zeiss 50mm lens. Aperture not working properly. Please watch the video. It will get stuck at f/4 and then start inverting and jumping around in a weird erratic motion. Then it's wrong. So the camera says f/16, but it's actually f/4. This is not good. I contacted Amazon and after 4 or 5 days my 30 day return window was up and they said I had to go through the company. I contacted Fotodiox and they sent me another one to try for free, but it didn't work either. I asked if a refund was possible and they said I had to get it through Revain. Now I'm sitting on this piece of shit and I have to sell myself. I am going to buy a Sigma MC-21 and am hoping to get some of my money back for this adapter. This gave me a huge headache and I really wish Fotodiox would do more to help me. I would not recommend this product, especially if you have Zeiss glass. If you buy this make sure you test your entire jar thoroughly. I don't usually write bad reviews, but this one hit me hard.
