I trusted Sigma telezoom product longtime ago as i was in Vietnam , that is why i bought a Sigma 50_500mm HMS DC OS in 6 months ago , at first , i worried a lot but after i and took picture on a lot close up portraits for customer wedding and all of results was perfect , real color and no blurry at all because of both 50_500mm and 18-250mm are OS (i did not use tripod ).I am really happy as i decided to buy Big Sigma 50_500mm , it was Canadian $ 1999.00 . Like i said above , my tests and wedding's results was good , so that made me more confident to buy a 18-250mm DC OS HSM , my tests from Sigma 18-250 was super clear , sharp and perfect color pictures , from results , i thought myself that why do i need all of lens that i must be useful for my Pro Photographer is NIKON , Nikon is the famous brand name , world class i knew that but so expensive .That is why i mention more Sigma lens that i can afford for both of Pro and hobby. I love the way that Sigma manufacture designed for both of lenses that i own , looking strong , nice , handy and easy use. Nothing to say more , i love Sigma lens

Because my only lens is the Nikon 18-105mm, I was really excited about the zoom length on the Sigma lens because I was going on an 8-day road trip and wanted an all-around travel lens. However, prior to leaving, I practiced with it and ultimately returned it because of the lack of sharp detail that I am accustomed to with my Nikon lens.

Because my only lens is the Nikon 18-105mm, I was really excited about the zoom length on the Sigma lens because I was going on an 8-day road trip and wanted an all-around travel lens. However, prior to leaving, I practiced with it and ultimately returned it because of the lack of sharp detail that I am accustomed to with my Nikon lens. Also, the Sigma lens was beyond slow to focus in low light; it was almost impossible for this lens to focus in low light at all. To test the capability of the lens (believe me, I'm no lens expert), I took the same images with my Nikon and had better clarity at the 105mm length than at 100-200mm with the Sigma lens. Shooting at a closer length on the Sigma was pretty comparable in clarity but not worth keeping the lens for. I exchanged it for the Nikon 70-300mm VR lens and I've decided to stick with Nikon lenses from now on.

Haven't used the lens that much so far, but initial impressions are good: Pros: Quiet and quick auto focus Good image quality for landscape photography Good zoom range for a multi use everyday lens Cons: Heavy Stiff zoom ring/function
I really, really, really wanted to love this lens. I did a lot of research on my options in this pirce range and the fact it is built is Japan was a major selling point. THE GOOD: Well built with a sharp and clear visual through my DSLR. Operated smoothly and had a feel and look of quality. Quiet. THE BAD: I'm only guessing it was not a good match for my Nikon D7100. Auto-focusing seemed inconsistent and fickle at times on the auto mode. Exposures seemed unpredicatable in any auto mode. The color did not match the quality of my Nikon lenses. One big surprise was that my 200mm Nikon got me just as close to a subject as the 250mm Sigma. I really wanted to love it, but after 1000 test shots - I decided to stick with Nikon products and will simply have to save up more cash to do so.
This keeps my lens switching in the past. So far the images are clean, crisp and sharp. Sigma makes fine lenses.
I bought this lens to replace my kit 18-55 and 55-250 canon lenses. Pros: 1) Great range. No need to swap lenses on a casual photography outing. 2) Well built and looks like it can take a beating 3) Included lens hood is a bonus. Cons: 1) Fine focusing at longer zoom is not great. unless you are absolutely still forget taking any images at near maximum zoom without a tripod. 2) Lens is slow to focus especially in low light.
I really haven't had time to assess this lens properly. So far, its relatively small, feels great and functions as advertised. For $260. with waranty, this was an exceptional purchase. (I should've bought two).
I returned this lens. There was an issue with the auto focus motor. It continually ran and drained my camera battery quickly. I typically get days of shooting out of a battery and with this lens attached I got 3 hours. I could feel the motor focusing even when my finger was not on the shutter button, Very stiff to attach to my Nikon D7100 The zoom photos I took with it were very nice and sharp and the stabilization feature is great . I also like the lock to prevent lens creep. Not the best in low light. For the price its a nice lens mine just had a factory issue. Adorama has an awesome return policy and service!
Overall, better than two kit lenses put together. On my D7000, it is bright enough. Surprisingly sharp throughout focal length. Auto-focus is fast, quiet, and accurate. It searches a little in low-light, but not too bad. Lens creep is a small issue, but the lens lock works well enough for me. Feels sturdy and tight (maybe a little too tight). The hood is nice, but it took me while to figure out that it won't lock in place unless the Sigma logo is on the bottom. Packaging is not fancy or careful like Nikon; my lens cap came wedged on crooked and there was no bag, but that's OK if it's not a sign of lens quality. I'd give it 4.5 stars if I could, but I rounded up because of the price. I'd buy it again in an instant. It will stay on my camera 90% of the time. The versatility is wonderful.
I'm not a pro, and this lens is really great for beginners!
I regret not buying this one earlier for my Nikon 5100. My original Nikon 18-55mm lens did its job, but a lot of times it doesn't give me the reach that I want to get to. I could have bought another longer range lens, but didn't want to carry mutliple lens. This one gives what I need. I have this one for about a month, and so far I am very happy with its performance.
WARNING! If you have a full frame camera do not buy this lens. compatibility check says this lens will work with my Canon 6D. Only if you want a circular photos from 18mm- 100mm and a vignette around each photo at 250mm.
