Has anyone tried Canon lenses on the Q/Q10?

Hi, I'm a new Pentax Q10 owner, and loving it so far.

My main camera is a Canon D-SLR, and I'm considering getting an adaptor for the Q10 for my Canon lenses.
Does anyone here have any experience with Canon's lenses on the Q? I think the two lenses in my collection that are likely to be particularly rewarding on the Q10 are the Canon 10-22mm 3.5-4.5 (because it'll have a nice field of view for regular use on the Q) and the Canon 60mm Macro (as it's incredibly sharp so it should offer a good optical resolution to the little sensor).

I haven't tried it, but supposedly they will stay on whatever aperture you last used on the Canon camera. There will certainly be no way to change the aperture while on the Q.

I also wouldn't expect the 10-22 to be anywhere near small enough to actually want to use it on the Q, but that might just be me.

I imagined I'd only be able to shoot wide open, but I'll try it and see how it goes in the new year. (My other adapted lens, an M42 135mm /3.5, has an aperture ring).

True - the 10-22mm is a big, chunky lens so I wouldn't be walking around casually with it fitted, but it would be fun to try and I suspect with the Q10 and wide open could produce portraits with a certain "feel" to them. And its likely the best quality "standard"(ish) length lens I'd have the opportunity to try on the Q10. (Weird that an ultrawide from my Canon becomes a standard/short-tele zoom on the baby Pentax)

My 135 f3.5 is my favorite lens on the Q makes a nice small package for a super tele. The issue I have with zooms is you can only set one focal length for the SR and as most adapted lenses turn into tele's you need the SR. Have fun with your Q, every lens turns into a new experience with it.

Hi Neil,

I believe I've read this, by might be mistaken. . .Something to try for th EOS lenses is to mount them on your DSLR and set the aperture, then remove the lens. IIRC, the aperture will stay at the last setting when the lens is removed -- not very convenient, but if you find an optimum aperture, you can just set it there for use on the Q.

That being said, The Q does not discriminate. I have a beat up (cosmetically, but with great glass) old FD 300 f4 L that was converted to K mount, and the Q likes the Canon optics (so does my K-5IIs for that matter)

I have a few fast Canon FD's which play nice on the Q, but no more EOS lenses. They all left at the same time (long ago) when I sold the 1Ds and 20D and switched to Pentax...

snostorm - I've heard that you can set the aperture that way too, although I've not tried it yet.


Anyways, I've just ordered the EF lens to Pentax Q adapter. I don't know yet if it will take an EF-S lens; I suspect it may not.
Once it arrives, I look forward to trying out the Canon 28/2.8 and 50/1.8 and Kodak 80-210 4.5-5.6 lenses on the Q10 (as well as EF-S 10-22mm and 60mm macro if they will fit the adapter); I'll report back how they get along together.

I purchased the Fotodiox Q to EOS (EF) adapter to try several lenses I was given. The lenses were old AF consumer grade zooms and didn't perform as well as my Pentax consumer zooms. Once I set the Aperture set on my old film EOS body and removed the lens it stayed at the aperture selected and I could shoot and manual focus with the Q but not change apertures. The main issue is the adapter does not have a shutter and will cause some jello in the images due to camera motion. Don't pan action, but other than that it works.

My adaptor arrived; the EF-S 10-22 would mount on it, but wouldn't lock in place. It should be usable with the EF-S lenses though.

I've been using the FD 400/4.5 (K mount adapted, then to Q) .. it's becomes a very sharp 2200 mm super tele!

Interesting. how did you get it adapted for k-mount

Agreed. Stop it down a little, and the Pentax M 135/3.5 is a competent little performer. Plus, it's crazy to have what amounts to a 750mm super-tele in a lens that's 2.5 inches long. And it's got a built-in hood!

Not to throw cold water on the OP's idea, but having to mount the lens to a DSLR to set the aperture sounds like a big pain. Personally, I'd pick up some cheap lenses you didn't need to do that with. C-mounts, Pentax K, M42, or M39 lenses are a few that have worked well for me.

Wasn't too bad really. Once you take the tele FD mount parts off, there's a lot of room left to make up for the different register distances. I bolted on one of the flanged M42->K adapters, it's a nearly perfect fit. It will then focus to infinity & beyond (it was made that way anyway). The only real tricky part is making a lil actuator arm to manually work the aperture iris.

I use it wide open or nearly open most of time though, it really is an awesome manual tele, internal focusing close to 12 ft & beautifully made to last! On a DSLR it's a 600, so you can still do excellent BIF after some practice. On the Q at the 2200, obviously tripod-only!

I have two lovely M42 lenses (Jupiter 9 and Jupiter 37A) with manual aperture, and the 25mm/1.4 C-mount you see so often on eBay, and have had the Q adapters for them for a long while.. BUT, I have a big stack of Canon EF and EF-S lenses that I work with on my D-SLRs (10-22, 28 2.8, 50 1.8, 60 Macro, 80-210 4.5-5.6, plus barely used 17-55 and 35-80), so for the cost of an adapter it's fun to try them on the Q. Sorting the aperture that way does sound a pain, and for that reason I'll probably shoot them wide open often (at least, for the purposes where it doesn't matter if they're a little soft due to being wide open)
