MD to AF adapter

I recently purchased one of these adapters and was wondering if I could use an MC mount lens too. Also, since I'm just searching for prime lenses for this, which ones are considered good? Any comments or advice will be well taken. Thanks.

MC will work, but everything is in manual mode, including the apreture, no auto-stop-down. 7D has a default setting preventing you from opening the shutter without a lens attached. You need to turn on RP (Release Priority) to allow 7D to fire the shutter without the AF lens.

Hope this help.

I think you mean to turn off the "shutter lock" to allow it's use. Thanks though, the MC lenses gives me more choices. I'm just looking to shoot primes with this thing.

I have the thin no name adapter that adds 1.2x to the focal length and have used various MD/MC lenses on my 5D. I have mainly primes but also some zooms. The primes are much better to work with. I can't really tell you with certainty which are considered good and which are not and while I have been only buying bargain priced lenses (including ones that will no longer close the aperature automatically - we don't need that unless we would also use them on a film camera) I only buy them if the aperture is around 3.5 or larger.

Having said that I have noticed that I can't really take advantage of the lenses set to wide open without getting a lot of flaring of the highlights. Most of the time they have to be stopped down a bit. Many of the lenses are very sharp, some I would say sharper than most of my AF lenses (I don't have anything expensive - and no G lenses) I haven't done any comparisons but I think my Vivitar 180mm/3.5 is one of the sharpest I have.

I think adapter is fun to play with. I agree with you if you have good glass you get good results. However, you also lose about 1/2 or 1 stop due to adpater which makes you lens slower plus as you said you can not use your lens at the widest, you need to close at least one stop. so... your 28mm 1.8 lens becomes about 50mm f/4 lens.

however, it is still great for macros, I had couple good macros and zooms, they are quite cool. since you use tripod for your macro, it is ok despite all the stops you lose due to side effects.

To the best of my knowledge, there's just an extra tab on the aperture ring which engages with a small contact pin on the appropriate camera bodies to indicate that the minimum aperture has been set (important for shutter priority and programme modes). On early models, there was no lock.
For use with an AF-to-MF adapter it is unimportant.

I just purchased one of the M42 adapters and a 135 2.8 lens. The lens was $10 and the adapter cost $15. It was cheaper than going MC/MD route and didn't suffer the conversion factor.

I've yet to see how it'll compare to the "real" 135 I also have on the way, but it'll be an interesting comparison to see if 10x the price is worth auto focus and aperture on a lens that will be primarily portrait shots.

With some lens (28mm 2.8, 50mm 1.7) you can't focus to infinity.
The adapter is very good with tele and macro lenses.

There is also an expensive (60$-70$) Tamron Adaptall-AF adapter, without optics and conversion factor. Excellent results with a Tamron 35-70mm and the SP 90mm 2.5 macro (payed 40$). The old mf macro is bettter build, full metal, than the new AF version and I don't need AF with macro work.
