Tamron 70-300mm F/4-5.6 Di LD Macro 1:2 Reviews

I bought this lens along with a tele converter which I sold giving me the lens for a mere $45. I have owned three Sigma lenses of the same focal lengths which were all disappointing,while this one is nice and sharp, quite compact, very light and fairly fast. I regard it as the best of the cheap longer zooms. It is the best one I've had. Definitely better than the Sigma's and the Canon 75-300 IS zoom.

Good quslity for the price. Some chromatic aberrations noticed at focal length above 200mm. Produces high contrast shorp pictures with all detail possible...

thumbs up!!!

Good lense. Excellent at wide-end and bit softer at 300mm tele end. Please see visual tests here:

This lens is light and small given its focal lengths. Sharpness is excellent at 70mm, decent to about 180-200mm, and not so hot beyond that point. This lens is definitely better than Pentax's 50-200mm f4 but I am sure that there are sharper zoom lenses out these in the 150-300 mm range. I just haven't found one and I doubt that such a lens would cost a mere $150 USD or so.

I love this lens used in the right way.
It is sharp between 70-150 f8 and i always use it at f8, beyond 150 it gets softer but useful to about 220. Light and compact. There are some problems with purple fringing so dont use it in high contrast areas in bright sunligt.
