Sigma 18-50mm f/2.8 EX DC HSM Macro Lens for Nikon DSLR

Got this lens couple of months ago for my D90 body. Absolutely love it!!! Build quality is great,price is reasonable,heftiness just about balanced with a D90.Having a blast taking close-up pictures of my kids with that 2.8 aperture. Only thing that needs getting used to is the opposite rotation of the zoom lens compared to Nikkor lenses.Otherwise this lens is highly recommended!

I bought this lens 1.5 years ago, and it was my main lens. Used it a lot, traveled a lot with it. but suddenly my camera (nikon d90) started to show the "F--" error and now this lens stopped to work.

Sad I live in brazil and I forgot to register mine for the extended warranty.

I thought I would write a review today as I purchased this lens some time ago and have had a chance to use it. It has worked out for me quite nicely. It is a fast enough lens for me to do nice indoor shots with minimal light. The quality of this lens is great. Sigma knows how to make a lens!!

I was a little reluctant after reading lots of comments on various sites about this, but I decided to give it a try. The sharpness beat my expectations. I have heard of people complaining about softness and front focusing, but I have not seen either.

I was also surprised the HSM motor. Mine is very quiet and very fast. I have the excellent Nikon 18-200 VR and I would say that the focusing speed is maybe not quite as fast, but very close to it.

I would recommend this lens to anyone who wants a f2.8 lens in this zoom range.

I switched all kind of nikon lenses, and 1st time decided try 3rd lens party, and i don`t regret , its a great lens and f/2.8 make this lens number 1 in price range 420$.
