Sigma 170-500mm f/5-6.3 DG RF APO Aspherical Ultra Telephoto Zoom Lens for Nikon SLR Cameras

I didn't have much of a budget w/ which to shop for a long telephoto lens-about $500. I was able to find this lens (APO only; not DG,RF)at a reputable on line photography outlet(used, excellent quality) for that price. Eventually , I spend about $60-$70 more to buy a Tiffen 86mm UV filter(coarse thread!)to protect large, exposed front element (from same outlet) & new hood (directly from Sigma)My first shots were disappointing but I expected that. I've achieved better results after learning to: shoot from a steady tripod w/ a remote release or even handheld at very fast shutter speed - 1/ 1000 or faster. depending on light, try to stop down (from 6.3 to f /8 or f/11 too.Then, if willing give up some distance (use 400mm VS. 500mm)this seems to produce a better photo. I'd like to experience "pro" Nikon glass, but couldn't afford to go there. Hope this helps.... Pablo (p.s. check out sigma 170-500mm photo pool on FLICKR; my photos are of humming birds, deer, etc.)

This lense was just what I was hopeing for. I needed the 500mm for my wildlife photography and once stopped down a click or two it was very sharp. There are other lenses that are sharp too but they can't touch this price.Very happy with my purchase.Ed

最高！信じられないほど良い、信用出来る！

I was looking for a longer lens for wild life photography. As the Nikon AF-S VR 70 to 200 F2.8 is a fantastic lens, but a little short for this job. I trawled the net searching all the wildlife club sites etc, searching for a lens that would meet my needs.To my suprise the Sigma 50/500 kept cropping up.When I finaly made my mind up that this was the lens for me, I contacted Simply Electronics and besides getting the lens at the best price from them, the lens was delivered in double quick time.I received emails at every step from confirmation of my order to the tracking number and then to the esitimated delivery date and finaly wishing me the very best with my new purchaes. I can't thank Nancy White, from Simply Electrics enough for all her help.Well now, I was'nt disappointed with the lens. It did every thing that I asked it to do and then some. The lens focuses extremely quickly and is spot on every time. I then purchased the Sigma 2x EX DG APO tele converter and fitted it to my Nikon D200 and then to the 50-500 lens. Well! you can pick out a sparrows toe nails at 800 feet! The only gripe that I have is that with the tele converter on, you can't use the auto focus, which can be a bit of a pain. But the combination is fab.This combination I feel is a must have for any serious photographer.Cheers.Mike from Ireland
