Originally posted by vroger Hello, I'm new so I figured I would start my 2nd post with lots of questions.
I've been enjoying Using manual lenses with my Canon EOS-M and it's a growing collection. Can someone give me some insight on if there are any sensor hitting problems on the Pentax k30 / k50 like on Canon EOS camera's?
What about using older lenses? I understand that older pentax work as long as they mount, but I have a lot of M42 lenses. M39 Lenses. Some Minolta MD,MC, Canon FD, Exakta. Do adapters exist for these? Do any have AF confirmation, aka a red focus point that blinks? Does focus peaking work for these lenses? Lastly any chance of adapting any of my newer Canon EF lenses? (even without AF)
I am looking for a full sized DSLR that I can use with my older lenses. I actually enjoy my Canon 5Dc, but alas , most of my older lenses have mirror clearance issues. And of course no focus peaking, or zoom features.
Thanks I'm sure I'll be learning a lot.

Welcome to Pentax.
To make a long story short, Pentax K bayoneted lenses will work on any Pentax DSLR and you can meter in manual mode using stopped down metering.
M42 lenses will work when using a suitable M42 adaptor. Depending upon the lens, you may need more than one adaptor, the genuine Pentax one is good for any lens that has a A/M switch, or is a preset (fully manual aperture) lens, but "auto" m42 lenses without an A/M switch, require a slightly different adaptor that depresses the aperture control pin. There is also a simple mod to the lens that can achieve the same effect.
M39 lenses usually come with an M39 to M42 adaptor.
Canon, or Minolta lenses cannot mount directly and require a special adaptor to achieve infinity focus, because the canon and Minolta systems have a shorter registry distance (lens mount to focal plane) than Pentax. So even if they did mount directly, focus is not possible. The adaptors have glass elements that are effectively tele converters. Optical quality of these adaptors is not great. As a result, especially the older breach mount canon lenses are somewhat of a orphan as even cannon abandoned its user base in the late 1980s
Nikon mounts are very close in design to Pentax, and while they do not mount perfectly many people claim that they are useable.
Lastly, there is one person out there who has patented and gone into business making an aftermarket lens body side lens mount that accepts several different lens systems. Check this link. The adaptist is a forum member also
