My dad has an old Sears KS-2 + 50mm f/1.7, which from a bit of research seems to use a Pentax K-mount.
I've looked around a bit and found a Pentax to Canon adapter, which says it supports af-confirmation, and costs ~$30 US.
Has anyone tried using an adapter ring like this, and if so, would you recommend doing so?
I am perfectly happy with shooting manual, but I'm curious about the quality of older lenses. I'm assuming that if I use older primes the optical quality will be fine, and it looks like the build quality of the older lenses is much better that similarly priced new lenses.
