Just saved up some hard earned dosh to by myself an F5. I love it compared to my old F90x but iam intrested in using the new range of silent wave lenses... My question refers to Sigma's EX 70-210 2.8 HSM lens.. I would like to know whether anyone has this lens or has used it? I was looking at the Nikon AF-S equivalent, but It is still a little expensive at the moment...
A friend of mine has it, and I have had the opportunity to test it against my 80-200AFS lens. Optical quality is very similar with the Nikon edging out the Sigma when shooting wide open, while this was noticeable on resolution targets it probably wouldn't be much of a factor in actual shooting. Focusing speed, the Sigma does a fine job keeping up with the Nikon. Build quality, the Nikon has a definite edge but the Sigma EX series of lenses are well made and should provide good service.
A friend of mine bought 3, each were "lemons" right out of the box. The third one smelled funny. Like the rubber-gaskets when they start to decintegrate. I agree with the others in that you take a look at the Tokina's... They seem to be a much better deal for the money.
HI, I have a friend who has a few Sigma's and even though the EX models appear to be of better build quality than their non-EX models, they don't appear to match that of Nikkor or Tokina AT-X Pro Series lenses. So even though they have decent optical quality as Frank states and from what I have seen, I also have to agree the build quality is not up to Nikkor or Tokina. I have used Tokina AT-X Pro lenses now for many years and have been totally satisified. The are constructed with aluminum barrels and great optics.I also have some Nikkor and again both the optics and the construction are great. I would suggest finding a store (or stores) that sell Nikkor, Sigma and Tokina and compare them one-on-one. Good luck, DD
