I found an old Vivitar 400mm f6.3 that's as clean as if it were just out of the box, but alas, no way (yet) to mount it to an EOS body.

It's a T4 mount...any clues?

Thanks!

You can get a M42 adapter for that T4 then buy a M42 to EOS Adapter. You can find a M42 to Eos adapter here...http://www.fotodiox.com/catalog/prod...roducts_id=124

The M42 T4 mount can be found on Ebay almost every day.

Put the 2 together and the lens will work on the EOS camera. Be sure to read the info on Fotodix web site about the camera metering and focusing. If you cannot find a M42 T4 mount, then PM me and we will try to work something out.

You are very welcome. Are you sure this is a T4 and not a T or T2 mount. Do you have a photo of it you could post here?

As far as the photos I've seen, it is identical to a T4.

I will proceed with the M42 adapter...I needed one anyway.

Thanks again.

Dawg,

I think that you must be the one who can answer my question. I just bought a Tokina/Vivitar 200 f3.5, just like the one that you seem to have. It is a M42 mount, but with the Pentax K mount adapter, it will not stop down for metering or for the shutter unless I am holding the little rounded off "M" lever. What am I doing wrong, or do I need to find another T mount adapter for Pentax?

Additionally, I haven't found instructions for removing the T mount. It looks just like the ones in your photos. I assume that the aperture ring must be in a certain place to remove the mount, but I don't know where that is. My copy is in perfect condition, but I don't know how to use it!

For your first question go here. READ ALL OF THIS BEFORE DOING ANYTHING!!! You'll see why I say this when you read it. http://gabriel.mp3-tech.org/blog/ind...y090314-192403

For your second one...there is a Plastic block with O-L on it and arrows pointing in opposite directions. Set the Aperture ring to F/5.6. (you'll notice it is a different color than the other numbers and usually raised above the others. See photo.....
Now depress the metal tab sticking above the afore mentioned plastic block, and turn the very back ring of the lens mount (The one the plastic block is mounted on) counter clockwise with the lens mount end of the lens facing you. It should rotate and come off. The "O" on the plastic block is for Open and the "L" is for lock. follow the arrows. Here is another look at the TX mounting system which is almost identical to the T4 system. http://books.google.com/books?id=GQE...20lens&f=false
