Yes
Will this lens AF . In other words does it have an in built motor?
 
Tamron's built in AF motor is really very slow.

I wouldn't buy any macro lens AF in mind (and macro is best done manually focused), but be warned. Macro lenses tend to "hunt" anyway in autofocus, but with Tamron's icky motor, I'm not sure this will be an ideal combo.

Optically its a great lens, but don't have high expectations for AF performance.
 
yes it is slow but I used mine for an indoor show jumping event and it was fine using continuos focusing. Try using it for one off grab shots and you will be frustrated by the number you miss, better to MF and/or prefocus. Very sharp lens and recommended however.
 
I have an older copy of the Tamron 90mm and it's screw driven - it doesn't have a motor in the lens. When I use it as a macro, it's almost always in MF, although all my bodies do have the motor in them.
 
Got one for my D40 and got used to MF. When I moved up to a D90 I was initially thrilled that the lens would now AF. However the thrill didn't last long. Very slow focus in the real world and for macro I still use MF.
 
nteresting comments... My great love is macro and I've only just gone digital. Really unsure as to what lens to get - I have a Canon FD fit 90/2.5 SP and that is superb on my F1N 35mm SLR. Is the Tamron SP90 (£349) that much worse than the Canon 100mm L series at £809?
 
optically the tamron is excellent, I doubt there is any real difference between it and the canon/nikon equivalent. Its just the focus thats a bit slow, and if using it for macro then its manual focus anyway.

As a portrait/short telephoto its very good, rather than moan about how slow it focuses its best to use it and get used to it, its a very good lens.

You cant go wrong with this lens IMHO....its excellent value
