Sigma DC 18-250mm f/3.5-6.3 OS HSM

all in one camera Lens I have been using this lens for about a year and it works great. It is multipurpose use and I don't have to carry extra lenses to do different types of shots. I mainly do wedding photography and it takes great portrait and group photos without having to use an additional lens. photos are very sharp and colors are great. I should have bought this lens years ago, now I know its better than my old ones. It shortens my Photoshop touchup time.

Sigma zoom is excellent Based on limited use so far, the Sigma lens is excellent. Nice and sharp, clear pictures. Handy for general usage since its focal range helps you not to have to change lenses frequently. Smaller than some comparable lenses it is lighter and less bulky yet retains the quality Sigma is known to give. I bought it mainly to use as a travel lens on my Canon.

Sigma 18-250 review On the plus side it has a nice range 18-250, the Nikon 18-200 seems to stop short. I have one of each. There is no coloration differences that I notice between Nikon and Sigma There is very little image differences sharpness, distortion, etc. The price with the new Nikon this was almost $200 less On the negative The optical stabilization on the Sigma makes makes the image jump as it comes back to life. When using the lens if you have not auto-focused (activated the mechanism) then the optical stabilization goes to sleep (powers down)and when you compose the image the OS activates and changes the composition. This is NOT a problem but can be an irritation when doing sports. The Nikon does not do this I am not sure why. I like the lens, but if I do any more sports I may sell it and buy the Nikon. I have been a photographer for 40 + years but I am not a tester and do not do actual resolution tests, but I do understand the errors that can be in any lens.
