Tamron 17-35mm f2.8-4 Di LD Aspherical

Review Date: May 3, 2005 Recommend? yes | Price paid: Not Indicated | Rating: 8 

Pros: Good price compared to 17-40 L, solid build, very sharp for most of the image.
AF a bit noisy but it's not that important. Goes slightly soft at edges but this is expected.

I bought this lens after reviews on this site and a comparisson I saw of this and the 17-40 L which showed it was just as good. Like many I could not afford the canon 17-40 L, especially in the U.K where it is almost twice the price of the lens in the US. The lens seems quite big to me with 77mm filter thread but apparently it is compact compared to others in this focal length. I saw the 17-40L and that looked huge ! Having a zoom at this length actualy seems like a good idea so you can compose correctly before any cropping that would result from using a prime.

It seems very sharp, not as consistently as sharp from centre to edge as the canon ef 50 1.8 but much better than the 18-55 efs kit lens. There is a slight yellow cast which can be adjusted in photoshop or raw later and it seems nice and contrasty. I feel glad I purchased it as I was missing the wide angle element in my photography. It would be nice if there was a hyperfocal scale distance on the lens but this is common to new lenses which do not have adjustable f-stops on the actual lens, (all done via the camera body these days). The lens does come with a chart though and I worked out that if you set it at 3m and use F8 you generally get 1m to infinity in focus at 17mm to about 24/ 28.
