Professional Photographer, June 2007... thats one of the 3 magazines that I read the shootout containing:
- Tamron Sp AF 17-50 F/2.8 XR LD
- Nikkor AF-S DX 17-55 F/2.8 IF ED
- Sigma 18-50 EX DC HSM Macro
Sigma eeked out a win. Same results in 2 other magazines, giving it 3 out of 3 wins. Putting it up against Nikon's 17-55 (the previous class leader) and beating it in near all catagories, especially sharpness, throwing it in a free 3:1 macro and then pricing it at almost 1/3rd the cost of the Nikon... well, there are times that it is good to stick to brand names, and times when not to do so.
It is just that the 3 lenses chosen by the OP are all of very low quality and results using all of these lenses will be less than favorable and if they could save a little more to raise their budget, I am sure they would be happier with those results over the lenses he chose.
Oh, I may have been a little grumpy, and I am sorry about that, but I do think I had a valid point.
