Daniel Acuña Posted December 19, 2014 Share Posted December 19, 2014 Hi,I just purchased my Gx7 with a Focal reducer (canon EF to MFT) and then I bought an adapter (C/Y to Eos) for my Zeiss glass but when I mount the lens to the Focal reducer it's very tight, I don't know if it is normal and I am scared of breaking something.Have you had this problem? Will the metal wear off with time or should I just buy another adapter?Thanks. Quote Link to comment Share on other sites More sharing options...
maxotics Posted December 19, 2014 Share Posted December 19, 2014 Had similar problem. Used dremel to sand between the mount flanges to fix. You just want to make sure you don't get dust in lens or anywhere else. You could also try using your wife's/girlfriend's nail file. http://maxotics.com/?p=296 Daniel Acuña 1 Quote Link to comment Share on other sites More sharing options...
Daniel Acuña Posted December 19, 2014 Author Share Posted December 19, 2014 Thanks for your help but where exactly do I have to sand it? Quote Link to comment Share on other sites More sharing options...
maxotics Posted December 19, 2014 Share Posted December 19, 2014 Hi Daniel, sorry, I don't know that mount, or have it in front of me. It might not be a good idea, or is a screw mount and can't really be fixed. I spent 20 solid minutes looking at the adapter and figuring out what the problem was. In fact, I don't think the idea of how to fix it came to me until later, when I had an "in the shower" eureka moment Then I had to find the dremel! If you're not mechanical you might just want to send it back. I mean, I would have done that if it hadn't come from China. If your adapter came from China, then you or someone might want to look at it. Sorry I can't give an exact fix. But I can confirm that they don't always fit perfectly, in fact, most of them have some fit "issue." Like that adpater worked fine on Panny cameras but not the BMPCC.

Daniel Acuña Posted December 20, 2014 Author Share Posted December 20, 2014 Ok thank you, I have two and they are both very tight, I am going to try to sand one of them a little a see what happens. Right now I can't buy anything else unfortunately I am on a trip, but could you recommend me a brand for the c/y-eos adapter andy?Thanks.

andy lee Posted December 20, 2014 Share Posted December 20, 2014 just get one that looks different to the ones you have - they are all cheap on ebay Quote Link to comment Share on other sites More sharing options...
richg101 Posted December 21, 2014 Share Posted December 21, 2014 I think it might be wise to understand the model of focal reducer that is being used. if of a split pin type retainer it could be that the split pins are just opened up too much and should get looser as you use it. personally before getting the dremel or emery cloth out, I would remove the speed booster from the camera and give the two a bit of force attach then remove a few times. remving the camera from the equation means the actual camera isnt being subjected to stress.

Daniel Acuña Posted December 21, 2014 Author Share Posted December 21, 2014 Thank you for your help, I found a solution, I just had to sand a little bit the 3 small parts (I don't know what they are called) of the adapter and it works perfectly now Quote Link to comment Share on other sites More sharing options...

andy lee Posted December 22, 2014 Share Posted December 22, 2014 conversrly if you adaptor is too loose I use cloth sticky tape and cut small 5mm strips and place on the edge of the adapter to take up the slack - add extra strips as needed to stop any movement .
