Sygma lenses give a great value for your money, my photographers used the 17-35mm with good results and I have the 28-300mm which gives my back a respite from the heavy 2.8 canon lenses. The only problem is that after about 2 years of heavy press work they tend to develope problems.

I am french and i used tokina 17/35 for interior pictures. I did not hadenough money to buy the Nikon 17/35 2.8 Iwas very deceived by a very poor contrast. However distorsions are well corrected and resolution is good. I was so tied to ask my photoshop to imoprove contast that I sold it for few money... I would like to know more about sigma 17/35 or fix focus 17, 20 or 24

I've just purchased the new version of the Sigma 17-35 f2.8-4.0 in Nikon fit. This lens is incapable of sharp pictures under any circumstanses. After performing hundreds of tests, it is apparent that the microproccessor is to blame. Try this test if you've got one. Set to manual focus and focus on a distant object. Set lens to 17 mm. On a Nikon rotate the focus ring whilst watching the focus indicator in the viewfinder. Repeat this several times but watch the image at the same time. You'll find the image blurrs while the camera still thinks it's in focus. There is too much movement of the focus ring before the chip can detect it.

There's another problem, when used in high speed mode for lets say 4 shots, the exposure varies. It is about as much use as screwing a block of wood onto your camera. I will be after a refund in the next couple of days.
