Tamron 70210 MF issues

I recently bought a Tamron 70-210mm f4-5.6 zoom for my Aria, thinking the price and weight advantage over the Zeiss VS 80-200 made it worth a try.

First results have been pretty good (what are other users' experience?) but I'm a bit annoyed and puzzled by the Adaptall 2 mount.

First, the set aperture isn't always picked up correctly by the camera, apparently caused by loose tolerance on the adapter's lever. I think this is a known problem.

Secondly, I seem to have the C/Y mount adapter, and not the correct Contax MM Program, which has been discontinued according to Tamron's UK distributors. Does anyone have experience of this adapter, or know where to find one? Does it work better, apart from making shutter speed priority and program modes available?

I think that you should check the Tamron website. I find it hard to believe that Tamrom would discontinue the MM mount and start making the older AE mount again when the MM mount works perfectly on the older AE cameras. Some of the mounts do loosen up with use. Did you get a new one? Jeff
 
Tamron UK actually closed last year, with all their business handled by a company called Intro 2020. The US Tamron site still lists all the mounts, and several US shops are selling them on the web. The UK business seems to be a bit of an orphan, with the distributor seeming to confuse "discontinued" with "not stocked".

I tried two new mounts in the shop, and both were at least half a stop out, both on my Aria and a new RX. A used one they had did seem even less accurate.
 
Hi Neels,

Tamron 70-210mm f4-5.6. I have used several Tamron zooms, I have been very pleased with the 80-210, the old 70-150 is not quite as good.

See my posts in the Contax forum on the Adaptall mounts. > First, the set aperture isn't always picked up correctly by the > camera, apparently caused by loose tolerance on the adapter's lever. Yes, this is irritating. But it won't affect your exposures.

Contax Program MM adapter. The tab allows the camera to "think" it has an MM lens on it. Whether the camera selected aperture is right on or not is not guaranteed, as it would be with a Zeiss MM lens.

I have both types of adapters, but, if you can live with the Av mode, I'd be happy with that. I note that the Contax MM adapters sell for a lot more than all the others (except the Leica R4), but you might find someone or some store that has one. Contax is still not that popular. Best wishes on the use of your 70-210 Tamron Tom C
 
Hi folks, there have been at least 3 different Tamron 75-150. I tried one of them (3.5) and it's been quite good(compared to some Sigma/Tokina/Soligor-Telezooms and the Yashica 135). I have tried several Tamron tele-zoom-lenses too and the mentioned compact one wasn't the best but not the worst either (the 3.8-4/70-210 wide opened has real low contrast). The best one is the 3.5/70-210 but I never tried the 2.8/80-200. Especially the build-quality of these big ones is MUCH better... The 3.5 is also nearly a macro-lens ! (YES i have the 2.5/90 macro too) Nearly same quality gives the 60-300 but there are at least 2 different versions with different optical quality - so take care. Sharpness of the Tamron-lenses is good but they cannot be compared to the Zeiss-lenses in contrast, color, vignetting and so called bokeh. I use many Tamron-lenses (I have Pentax and Canon and Rollei -for the Zeiss-lenses are much cheaper there- too) (28-70, 28-80, 35-135, 70-210, 90, 500, 2x-converter) and I'm quite satisfied with them but as you use Zeiss-primes you're infected by the Zeiss-virus : They're unbeatable ! (I even tried Leica-lenses but the 2.8/90 and 135-lenses weren't as good as the Zeiss-ones but much more expensive) Best wishes Paul
 
Hi has anybody used the SP70-210. Alreay have a SP300 its not upto Zeiss standards but its not bad and wins hands down on weight and close focus ie. Approx 4ft. which makes it a good len to go walking with.
 
I have the SP 70-210 f3.5 and find it quite good. Although it's good through out the range I personally found it best at f11. I have no problem recomending this lens. As for your SP300, it must be the f5.6 as I have used and find the f2.8 better than the CZ 300 f4. I also have the SP300 f5.6 and found it to be nearly on par with the CZ300 f4. Sorry, I'm no fan of this CZ lens. The CZ VS 100-300 is amazing though. Just what I found, Jeff
 
Hi Jeff thanks for the usfull and to the point information, managed to pick up SP 70-210 + 2x SP converter with cases in ex condition for approx £56 which included P&P and wire transfer of cash.So I'm a happy Bunny. As regards adapters I was told by a dealer with no axe to grind that there were two differant AE mounts made and that the first model had a grub screw that should be changed to set the max apeture of the attached lens.
 
>Hi Tom! I am interested in the topic about the Adaptall mounts MM/AE. But I could not find your posts. Could you give me a hint?
 
Hi Wolfram, I replied to a thread "Tamron 28-200" on 6/9/03.

I replied to a thread "Please Explain the Difference between AE and MM Lenses", on 5/15/03.

I hope this information is helpful to you.
