I have had a Tamron 70-300mm f4-5.6 SP Di VC USD Lens for a few months. I got a Canon EF-s 15-85mm f3.5-5.6 IS USM last week. When I tested the Canon lenses I tried some of the same shots at 70 and 80mm and found the Canon was very much sharper. When I zoom in on the images the Canon retains detail, for example wood grain on a shed where the Tamron becomes very blurred.
When I get the time I will put the camera on a tripod and rerun the tests but the results were so different I donít think thatís going to even out the results.
What I am inquiring about is will this be a good way to test I will try auto focuses on and off and if the original results are reproduced is this what I should expect (which would be disappointing compared to the reviews) or do I need to get the lens calibrated. If so does anyone know how long in the UK it is likely to take as itís a bit of a pain at this time of year.

I've had this lens for almost a year now and I'm getting very sharp results especially at the focal lengths you mentioned .However I've also had some unexpected results with occasionally soft images which I found difficult to explain until I realised that you need to shoot within 4 secs of activating the VC. This might not be answer to your problem but it's something to think about next time you shoot with it yeah ? I'd strongly advise to test on a tripod with the VC switched off ASAP just in case you have got a dud.
Just a note that I have these 2 same lenses.
I bought the tamron first and was not very impressed with it at all.
I eventually returned it to Tamron Australia who returned back to me as no fault found.
However, the results I started getting after it was returned were outstanding. Sharp as !
I now see very little difference with this and my Canon 15~85mm. If anything I'd put the Tamron as the slightly sharper of the 2
I use a canon 7D
Very happy with my Tamron 70-300 SP Di VC
