Has anyboby uses the adapter (RJ ?) from China for $49.99 and the one from Cameraquest for $175.00? Which one is better. Do they all need some kind of work on the lens (trim the pin) before it fit into the adapter? How good are these two adapters? if you own one, are you happy with it? if not, why not?
thank you.
 
I haven't used either one, but I am planning on getting the $50 Chinese one.

The issue is NOT with the adapter itself. The issue is that the lenses have an aperture pin that extends back too far, and would rub against a piece of the light box in the two bodies that use the side porro finder.

The workaround is either to carefully cut away part of the front cover of the camera's light box, or to trim the auto-aperture pin on the lenses by between 0.3 and 0.5 mm.

I don't know whether trimming the pin will prevent the auto-aperture mechanism of the lenses from being used on some Minolta film bodies, but that is certainly a possibility.

When I get my Chinese adapter, I'm going to experiment with a 28mm f2 Kiron lens and a 58mm f1.4 Rokkor, both of which have oily sticky aperture blades so the auto diaphragms won't work on film bodies anyways. They are both nice lenses when used on film, and the auto diaphragm is not used when manual lenses are mounted to 4/3.
 
i have one of RJ's & another the way. works fine. 20° off axis & works just like cameraquest only $125 cheaper. been playing around with a 35mm mc w. rokkor-hh f1.8 today. some of these shots are w/o.

I have some Rokkor PF and PG lenses used with a SR-3 which was made before any auto features were available. Will that adapter work with them?

I have been following threads regarding the Minolta adapters. Some users were having problems with quality control issues and not being able to focus to infinity. Do you know if these issues have been resolved?

I have the $50 adapter and it's very good quality and focuses to infinity. I haven't tried it on all of my Rokkor lenses, but it works great on the 4 I have tried it on.

I was the guy with the problem and RJ took care of it very quickly. I doubt it'll happen again.

I don't believe I've ever seen an adapter for native Sigma to 4/3. Most of the other lenses have been done, so you'd think it's possible - unless they don't have enough room from the mount to the film plane to squeeze in an adapter and still focus to infinity.

There's also the issue of not that many Sigma mount lenses being out there.

Thanks Jim!

I have a Contax adapter and have been using it with a 50mm f1.4 Planar. I have wanted to purchase an MD converter to try some of the Minolta lenses I have. I have held off after hearing of potential problems. Thanks for the "all clear"! --
