Good to know - thanks for the input.
I've been shooting the Canon 28-135 and have been generally happy with it. It gets a little soft north of 100 and the uber-cheap Canon 70-300 is pretty much worthless past about 200.
I shoot a lot - scratch that... I shoot pretty much ALL sporting events and need the ability to reach out further than 135 will get me. If I stay around f8/9, it's pretty sharp, but there's a significant change in the depth of focus. Would love to run a 2.8 lens, but then we're back to $1000+.
Hence, the look at Tamron...
Interesting to hear of the A/F issue - I wonder if there's a marginal problem with the fitment of the contacts...?
Being from NorCal, what do I know anyway???
