|comment:||For not a lot of money this lens gives good results in good light, although IQ seems to drop off quite sharply if the lighting isn't good. Shots in good light have good colour and excellent contrast and sharpness doesn't appear to tail off too badly at 300mm, which suits me - if I use a lens like this, I'm going to want to use it (and get good results) at 250-300mm most of the time. It would be better if the maximum aperture at 300mm was wider than f6.3, but I can live with it.|
Its unquestionably a 'budget lens' and doesn't bear up to very close scrutiny compared to more expensive glass (as you would expect) but is a clear winner on value for money. Although its light, build quality seems good and I've never had any problems.
Update: taken some more test shots now and in careful direct comparison with the Beercan and Sigma, both those other lenses have better IQ, but its pretty close and the Tamron is still good value considering its cheap price. It is also quite a bit lighter than the others.
