For some reason my 70-200 is not connecting tightly to the camera body causing problems. I am having the same problem on 2 different camera bodies, and I am not having this problem with any of my other lenses. So logic would say that it is a problem with the lens. The question is "how do I fix it?"

Have you asked the manufacturer? Perhaps you have a defective product.

You dont. Someone else does that. But only if its in need of repair. It could be inferior design in which case theres no fix. Since you mention no earlier time when it was problem free, it may very well be inferior design.

Indicating the make and model of your lens might generate more responses/help.
Better yet, post a high quality image of the mount.

No previous problems. Lens is a USD DI Tamron 70-200 F/2.8

Sounds like the mount is not in spec.
Why loose?
Hard to tell over the internet.

Is this a lens you just bought? New? Used? If you have had it for a while how long has the problem existed?
All my Canon lenses have a raised rubber lip around the outer edge of the lens mount. This seals the mount and helps keep the lens snug. It appears that yours does also, but what condition is it in? Have you compared it to your other lenses? Have you checked the mount itself to make sure it is tight to the lens? If both of those are good then take a magnifying glass and examine the underside of the three mounting flanges for any sign of wear. Compare them to your other lenses.

Depending on the ages of your lenses, Tamron warrants theirs for 6 years.

I don't know why I assumed you had Tamron lenes. I had just been reading some Tamron ads and all mine are Tammys.

It is a fairly new lens, in that I haven't had it that long, believe that I bought it new, but can't remember for sure. It's one of those things where it was working fine, and then it wasn't 2 months later. Crazy thing is that I can't find a serial number anywhere on the lens.

The OP said it's a Tamron.

If it is a Nikon, call 1-800-645-6687. If it is another brand, call the manufacture customer service and NICELY explain the problem.

Do you mean it doesn't lock securely or just that it has some play when mounted?

Have you checked that the four screws holding the mount to the lens are tight?

It might be as simple as that. Just be sure to use a good fitting JIS screwdriver (not quite the same as Phillips).

If they loosen again, remove one at a time and put a small drop of blue Locktite on the threads, then put back in and tighten. Don't remove the entire bayonet, because sometimes there are alignment shims under them. (Also DO NOT use red Locktite.)

If the screws aren't loose and problem persists, get in touch with Tamron. Especially if it's still under warranty.

The logical person would say that if it moves, you have a loose nut. Well I had 4 loose screws. Problem solved. Thanks for the input.
