See what an adapter can do? Of course focus is a little tricky cause this lens, the ‘FED Summar’ was collimated specially for its native body, which, I will totally casually add, is for sale in my store, bundled with the lens.
It’s a pleasant lens to use anyway, if you can endure the inconvenience of the focussing lever and the flare wide-open.
Someone once said that adapters were the most disruptive gadget in the camera industry: ten bucks and you can bypass the schemes of first brands. Of course, first brands don’t make them because they want you to use their lenses. Besides, it would be bad marketing for them to advertise that one of the advantages of your system is that you can use glass from competitors.
