kern switar 10mm won't focus to infinity

[David Dominguez]

Hi Everyone,

I just purchased a really nice kern switar 10mm preset. Unfortunately it won't focus to infinity. I was wondering if it was worth keeping and having a tech service it, or should I just ask for a refund. Is it fairly easy to fix?

Thanks for the help

So the focus ring reaches infinity but the image is not sharp?

Easy for a tech to adjust, bring the camera as well in case the flange depth is out.

ok good to know!

Correct focus ring reaches infinity but it's not sharp.

It's not the camera because I've tested on 2 different Bolexs and my other 10mm lens is sharp on both. 

Thanks for the hep, Dom.
