Re: Lens mount modification

I now have the answer to my original question. I am told that the flange screens the lens to prevent reflections from electrical camera/lens connections. The flange is longer than on most Nikon lenses (possibly because it is extreme wide angle) and it does prevent lens being mounted on some (probably a minority) of Canon cameras. Unfortunately for me, the 5D is one of the cameras on which it cannot be mounted.

I am told that the modification could easily be removed, cut down, and reinstalled. However, the Nikon 8mm also is slightly off centre for Canon cameras, and a small part of the circle is cut off on full frame cameras. So I have decided that it was not meant to be, and will be selling it on in the near future.

Hi Phil,

Apparently these kits are as rare as hens' teeth. The kit that I obtained came from http://www.pacificrimcamera.com/.

Jeb,

Well I just went over to the Pacific Rim Camera web site and they didnt' list any of the kits.

It doesn't surprise me that these kits would be hard to find. When Nikon first announced the conversion kit, I sent in four lenses to be converted. That was in 1977. I don't remember exactly when Nikon discontinued this service, but I'm sure it was over 10 years ago.

Re: Lens mount modification

Jeb,
I'm not sure but you might find something here:
Fotodiox.com
They seem to have a business built on adapters.
Good luck,
J.

Re: Lens mount modification

Sounds like the adapter and lens may not be mated properly. You could check if the lens and adapter are properly mated, and then if the whole assembly is properly seated on the camera. If that doesn't work, it just may be an adapter which isn't quite right.

Re: Lens mount modification

Here is a way an adaptor can be made. I have a 35 year old Minolta 58mm F/1.2 lens with the old SR mount. Over at the DPreview Sony SLR forums a member posted a conversion he made to that lens so in could be mounted on the Sony A100. He used a Minolta Maxxum T mount adapter, cut it down on a metal lath and by removing the camera mounting from the rear of the lens, mounted the new modi T mount to the 58mm lens.

I do not see any reason why a modification like this can not be made to adapt nearly any lens to any camera. I had him do this modification to my lens. He charged $80 US and I installed it in less than 15mins.

Just a thought.

Jerry

Thanks for mentioning this company. I've been searching high and low for an affordable Mamiya 645 to EOS adaptor, to no avail. I just checked and Fotodiox has them for $89.95!
