Hi, have not been here in a very long time. Life happens. The short story is, along with a few Tamron Adaptall and Adaptall-2 as well as Adapt0-a-matic lenses I own, I had, a few years ago bought a Tamron 300mm F2.8. For some reason the thing simply WILL NOT focus correctly, and I was never able to resolve it. Another of these popped up locally on C/L for 300. Very nice shape, with the case, the 1.4X converter, and came with a Nikon mount
I actually have several ways of mounting these Tamrons to my Canon EF stuff, including Nikon / M42/ Olympus Tamron mounts via those to EF adapters, AND I have three China/ import direct Adaptall -to- EF adaptors, but all three are somewhat loose and sloppy.
Anyhow I ran into TWO of what I've been told here and there simply do not exist----Genuine Tamron manufactured, Adaptall-2 to Canon EF mounts. All the way from Germany to the N end of Idaho state. I paid plenty, but on the other hand I just spent 2300 US for a brand new 5D Mk IV before Christmas

I have a spare Tamron EOS-M adaptall sitting around for few years. I planned to use it with the 180/2.5 but never get the chance to find one copy within my budget. _________________ https://lensfever.com/

They look like genuine Tamron-manufactured mounts, so obviously they do exist!
I have that same SP 300/2.8 (60B) lens, and it is quite a good performer for its age.
The green paint on mine was in terrible condition though (hence I got it cheap). I stripped all the green paint off so now mine is anodised black all-over with "custom" orange feet scale markings. _________________ Mark

I’m not sure why anyone would say they don’t exist, I’ve had a few over the years sneak seen plenty more. They are definitely more durable than the generics I have tried.
Asking prices can be high but I’d not pay much for one as you can often pick them up cheaply because sellers simply don’t know they have a relatively valuable adapter. In recent years same applies to the original Canon-made FD to EF macro adapter, sadly no one seems to make that mistake with the optical one… |

My understanding is that tamron started manufacturing these but then canon took legal action - patent breach or something. They basically didn't want tamron adaptalls competing with the canon lens line up I guess. So tamron had to stop making them but they do kick around on the s/h market. I've had a couple pass through my hands, sold on for a useful contribution to the kitty. The best trick to acquire one cheap is to spot one on a common lens like the 80-210's. I sold the ones I had for around £25-30 IIRC, which I would suggest is par. I certainly would suggest avoiding overpriced BIN's.
The situation with the similar minolta A (= sony A) mounts is the same I believe.

Thanks for replies. I don't know what the trouble is. (with the first Tamron 300/2. I can get an "apparent" sharp focus, using such as the live view screen, and I first started back with a 40D, then later a 7D, and it looks fine. but the result is blurry. I've taken lots of manual focus photos with various lenses, so I know my way around. There is no evident dust, junk, or fungus, etc, and nothing loose or rattle. I simply don't know.
I'm 74 now and don't do nearly so much. I won't be trying to get any moving shots with a big manual lens
On a side note I ALSO just recently bought another huge, heavy manual, a Tokina AT-X SD, 150-500mm, F5.6, for Contax. I already had a Yashica / Contac adaptor for EF, and it fits nice and tight. "The internet" seems to think pretty well of these, and boy is it a big heavy slug!!! Nice shape.
The only one I have that is larger and heavier, is the big ol Tamron Adaptall SP 200-500mm F5.6. That thing is TRULY a club of club LOL |

It is possible that at some point the rear doublet was removed for cleaning and accidentally re-inserted reversed; judging from the lens diagram in the link below that doublet looks near symmetrical externally so an easy mistake to make.

But there are other possibilities... _________________ Mark

I have had many of these over the years but I sold them. They brought quite a bit of money on eBay.
They definitely exist. |
