Not a huge image quality jump up from mid priced options
Good performer, a touch better than the mid priced lenses such as the big beercan or minolta 100-300 apo, producing a crisper image with less glow and CA than the older alternatives.
I'd say the G and sigma 100-300/4 are still better lenses but on a value for money basis, it seems to be the best option for someone looking to spend more than budget money.
One of the things I like about this lens is it's a decent size/weight that's manageable. It's shorter (but fatter) than the big beercan which makes the Tamron easier to fit into smaller bags and unlike the sigma 100-300mm f4 it's weight isn't problematic, it can be packed in as a just in case lens (just) where as I would be reluctant to carry the sigma around unless I was confident I needed it.
AF speed is okay but nothing special (seems to pause briefly when the motor needs to change direction, as if the lens is having a think about which direction to go), but then none of the other lenses mentioned are particularly fast IMHO. The (near) silent AF motor is a nice bonus from the older models.
All in all a good compromise on image quality, price and bulk, but I wish they included a focus limiter and VC.
