Re: New NX11 owner and a question about MF lenses

I use a pk to nx adapter for my nx10 system and mounted a 50mm 1.7 pentax lens on it. I get the same field of view as in my pentax dslr. From what I understand the adapters are designed to retain the same flange distance between rear of lens and the sensor. This is important if you want to attain infinity focus. But I found an interesting thing but yet to experiment as I dont have the required equipment and this in regard to canon fd lenses. To my knowledge if you want to use canon fd lenses in your dslr you need to buy an adapter which has a piece of glass in it. This is added to it for attaining infinity focus. This glass some say degrades the image quality. There are adapters sold without the glass but it seems you wont be able to attain infinity focus with it and can only use it for macro. Now here is the interesting part, the canon fd to nx adapter doesnt have a glass in it and it seems you can attain infinity focus when you attach a canon fd lens to your nx. As I said I dont have the equipment to confirm it but I found it interesting that you can achieve infinity focus in nx using a canon fd lens with a glassless adapter.

By the way the distance markings on your lens when mounted on an nx system will function the same way as they do while mounted on a dslr, that is no changes in subject distance [based on lens marking]
