Good things first: excellent, useful zoom range (ideal for garden birds, for example, which is why I bought it);
Images so far seem sharp throughout;
Lovely background blur at 300mm;
VC REALLY works - once it grabs, it doesn't let go. In favourable conditions i can shoot hand-held at 300mm as slow as 1/20th of a second;
Distinctive Tamron colours and image quality - a big pro for me.
Now for the downsides: this lens is LOUD in operation. The VC really lets you know it's locked on and then let go again, and whirrs constantly when operating;
the autofocus mechanism is also far from silent, demonstrating a distinct robotic, motorised whirr when changing from close to distant focus;
Autofocus isn't the swiftest;
Zoom ring is stiff and jerky at certain portions (between about 150-250mm);
It is cumbersome. It looks and feels daft on my piddly Canon 700D.
I have yet to decide whether my noise problems are the norm for this lens and/or whether i can put up with them, or if i've got a bad copy and need to replace it. Other than its loudness, i do really like this lens.
