Tamron manual I need the instruction manual

This is the manual for the Tamron SP AF 90mm
F/2.8 Di Macro 1:1 (Model 272E)

Repair manuals can be bought by certified repair centres. Sometimes you get the manuals when you have done the repair course at the firm. Not sure Tamron does so. But they most of the time don't sell these manuals to normal people, to avoid they start opening a lens, because they never will be able to put it together as a working lens, without the tools, like a collimator.

See if this site is of any help

Excerpted from a www.photo.net review of the lens:

Though the Tamron AF 55-200mm Di II LD Macro has "Macro" in its name, it's not really a macro lens. Maximum magnification is about 1/3 life size (Tamron spec it at 1:3.5) as you can see from the following image below, which was shot at 200mm and at the closest focus distance (0.9m/37.4"). This isn't too bad, but it's more of a close focus telephoto lens than a "macro" lens (bolding for emphasis added).

You can download the instructions from http://tamron-usa.com/about/manuals.asp

Only if you get the version with the built-in autofocus motor. The D3000 lacks a mechanical AF coupling so AF lenses which need to be driven by a motor in the camera body will require manual focussing.

Either way, you're far better manually focussing the Quantaray/Tamron 70-300mm: the AF performance is very slow, very noisy and hunts around a lot to achieve focus.

Although the Quantaray and Tamron versions are identical lenses, if you have to buy this low-quality budget model then go for the Tamron: it's absolutely no better lens quality (and usually the same price), but the manufacturer's warranty from Tamron is much better than Ritz and is internationally valid. If you resell the lens then the Tamron will have some value (not much though) and the Quantaray will be near worthless as it's not so widely known, and has a poor reputation amongst those familiar with the brand.

"Cheap" isn't always the same as "good value"...

You didn't supply what kind of Tamron lens it is. I'm gonna go ahead and give it my best shot on a guess: Tamron 28-75mm f/2.8 XR Di LD Aspherical (IF).

Hope this helps!

I'm not sure of the exact model number of your lens, but the hood should have a bayonet flange and rotating it in one direction or the other should allow it to then simply pull off.

Hey shutterbug72,
According to the manufacturer the first thing you should try is cleaning the lens contacts with an eraser. If that doesn't work you could try removing the battery and reinserting it to reset the camera. It seems to me that if there was a compatibility issue going on you should have seen that from the start. As far as what lens you should buy both Tamron and Canon make very good lenses, but with Canon lenses you shouldn't ever have compatibility issues. I hope this helps!

Sincerely,
Allan
