I have raised this issue prior on this forum, but not recently. Last time a number of workarounds were illuminated. But I'm wondering if anyone has found a source, with luck in China, for these caps.
When you try on eBay, only things coming up are rear caps for Adaptall lenses WITH adapters affixed:
http://www.ebay.com/sch/i.html?_odkw=tamron+adaptall+cap&_sop=15&_osacat=625&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.Xtamron+adaptall+rear+cap.TRS1&_nkw=tamron+adaptall+rear+cap&_sacat=625
These brand-specific caps are worthless. What I'm seeking is rear lens caps for Adaptall lenses WITHOUT an adapter present.
It's funny, I recently bought an Adaptall 2 lens without an adapter but with the original clear plastic Tamron rear cover. The lens was OK. But I bought it as much for that rear cover as for the lens itself. Those covers are as scarce as hen's teeth. And nobody in China seems to realize how desperately we need a supply. |

Many Tamron lenses, with the mount removed can use a Canon EOS body cap on the back of the lens. Tamrons with a rear element that protrudes from the lens have to use the genuine rear cap.
If I see adapters with the clear covers at the camera fair I just buy them regardless of what they fit or how many I already have, it's easier to sell the mount than buy genuine rear caps. _________________ LENSES & CAMERAS FOR SALE.....
I have loads of stuff that I have to get rid of, if you see me commenting about something I have got and you want one, ask me.

Thanks, Lloydy. Yes, I have been using the Canon caps for several years now where possible. I've even drilled out one or two of those and tried to jury rig a bit of extra length near the center, for those lenses requiring such a modification.
Really I was hoping that by now another forum member might have discovered a source for the real thing, when it comes to Adaptall rear caps. My goodness Adaptall lenses are out there by the tens of thousands!
You know, Lloydy, it's funny. Within the last year I put to rest all analgous problems with my T4 and TX lenses. A seller in another state sold me at low cost a large number of brand new (TX) m42 adapters, which (as things worked out) function well with both types of lens (T4 or TX). This solved my cap problems, as I simply fitted all my T4 (even the Soligors!) and TX lenses with the TX/m42 adapters, then finished things off with readily-available, inexpensive, m42 caps.
But with the Adaptall lenses things are different. The m42 adapters cost circa US$10 each! Perhaps what I should do is contact a Chinese adapter seller and try to negotiate a lower price for a quantity purchase. While I've not abandoned all hope, it appears as if Adaptall rear caps will never become available.

Hi, Edgar. Really I don't have an exact count. I would guess between twenty and thirty. And of course with a bit of luck that number will be growing! |

OK. I understand now why you need a low cost option for rear caps! _________________ "I've got a Nikon camera, I like to take a photograph" - Paul Simon |

I have quite a few Tamron lenses as well, but I've also picked up quite a few adaptall-2 mounts over the years, so I just leave the mounts on the lenses so I can use the camera lens caps on them. I have only a couple of the rear Tamron caps, so if a lens doesn't have a mount or a cap, I set it on its front and just rest a rear cap on top of it -- any old rear cap will do. _________________ Michael

Ok that's what those complicated Canon fd adapters are for.
I googled some and found you can download the rear cap:

If you can find a place to print it for you. _________________ pentaxian |

The original Adaptall caps where clear plastic & rather brittle. I have seen them for sale occasionally but only at silly prices. Adding an adapter can work out cheaper!
This sounds like an ideal job for a 3D printer to me. |

Seems to me that a 3D printer is ideal for just this sort of thing. Perhaps an enterprising soul with one will realize the need. _________________ Michael
