The adaptor seems to work better on longer lenses. How would it work on my excellent 500mm mirror lens?

I think it works without any trouble.The only problem I notice it was with my Shift Rokkor, because it don´t permit to arrive at the horizontal plane.With all my other Minolta lenses (20, 28,50, 50 macro, 100, 200 and 70-200 zoom) it woks just in manual mode.

I use it on a 70-300mm sigma lens with OK results. I tried it on a 12mm fisheye and the results were terrible.

I use this adapter on my NEX7 with a Minolta 50mm 1.4 and it works great. The problem is the camera doesn't recognize that a lens is attached. There is a setting to override this. On the NEX5n I don't know where it is, but it is there. Have fun.

i do not know, not sure if that is an adapter.. for larger cameras you don´t really need an adapter, just making sure you tilt the telescope in a different direction to counter balance the weight of the camera, otherwise it may be too much tension on your reflective telescope (in case it is a reflective instead of a refractor) Be careful though with the rubber tips the frame has to avoid damage to the lens since in my case those tips got loose due to the weight and almost the camera and the whole thing falls to the ground, I had to crazy glue the rubber tips to the frame and issue fixed...

I use this adapter with lenses that already have aperture rings and it works just fine. You just need to keep the aperture on the adapter open all of the way. It might be beneficial to just go ahead and buy this adapter instead of a passive adapter in case you want to invest in newer canon glass.

As it was said any times in the customer's reviews (including mine), the adaptor does not fit perfectly and you have to do a few tries before getting used to it. The main point is to put the lens aperture control finger on the good side of the adaptor aperture control pin to allow the aperture control dial to rotate. If it does not rotate, you are on the wrong side. Hope this will help. Richard.

The reason they put glass in some of the adapters is because otherwise you cannot focus to infinity. If the focal plane distance in your camera is short enough to accommodate the adapter, they would not put the glass in and the image would be as good as the original lens. I never buy adapter with glass in it. You defeat the purpose of adapting a first rate lens.

As a Wide angle lens it just screws onto the end of the 18-55mm lens. I didn't think that it would work and I was worried that it would fall off. but it doesn't at all. To use as a Micro lens it requires another adapter.

Short answer from me is no! I purchased the extender for my 70-200 f2.8 and it works perfectly. I tried it on my 100-400 4-5.6 lens just out of curiosity and the auto focus did not work. I did not play with it much on the 400. Perhaps others have made it work but not me. Hope this helps you...

Yes, I use this adapter with my OM 50mm f/1.4, 28mm f/2.8 and the 35~70mm f/4 zoom lenses. It has a nice snug fit and they all focus to infinity.

The answer is: Try lens adapter rings to fit larger lens filter. They're inexpensive and do the job.

I purchased this adapter so I could use my Tamron SP 55B 500mm mirror lens on my Canon EOS. It works fine. It also works for the Tamron 2x SP tele-converter. I would assume that it would work for any Tamron SP series lens. (Note, the SP series lenses were for 35mm film SLRs). I think the 75-300 lens is not in the SP series, so it might not work with this adapter.

Full frame A mount lenses don't crop using this adapter...nice adapter and AF works well...

Goodmorning. I have used this adapter on my SMC Takumar 50 mm f/1.4 on my Canon T3i with no problems. The lens only protrudes beyond the flange maybe an 1/8 of an inch. In fact it does not even protrude beyond the auto focusing contacts shelf (for lack of a better description). the Adapter is designed for the Modern Canon products. If you are using it on a camera that is older or one that does not have a Single lens Reflex (SLR) design this might be a problem. I would also take the adapter off to make sure the problem is not with the lens itself. It would be helpful to know what model/year Canon camera you are using to further understand the difficulty that you are experiencing. Goodmorning.

I have used the adaptor with 50mm f/1.2, 85mm, 35mm, 16-35mm,24-70mm, 100mm, 70-200mm and 100-400mm and it didn't make any noise. The problem could be you're having a defected adaptor or damaged lens contacts. In general, the adaptor works perfectly well.

No, the adapter is wider. You will have to buy a larger (58 mm, I believe) lens cap.

I think this is to convert either a Nikon or Canon lens to 4/3, body, my old standard 50mm Nixon lens works great with this adapter and with my 1st class Panasonic 4/3 camera and this adapter costs so much less and is of good quality, be careful as some that are made in China are very poor quality and poor fit as well. You can go on some of the photographic forums and receive first class advice from some pretty experienced people. Good Luck, Ray
