Have now used this lens for a week or so. We attend the Arizona Fall Baseball League for both day and night games. The Sigma 18-300mm performs well at both. The photos are clear and sharp at both ends of the spectrum, i.e., at 18mm and 300mm. No complaints.

This is a very good all round lens. If you need to travel light with just one lens, then this lens gives a greater range and flexibility than most other lenses. Performance is very good, but there are a few limitations as you would expect with a zoom lens of this range.

Results exceeded my expectations. Thoroughly recommended.

A great all in one solution for travel; Durable; Great Picture Quality; Lightweight; Simple Controls

I have only had it for a couple of days now but so far I love it. I have used it at my son's soccer game and just taking random photos here and there to test it. It is heavier than Nikon lenses but I will gladly deal with that instead of switching lenses constantly.

The Sigma 18-300mm 3.5-6.3 DC HSM OS Macro is another impressive addition to the Sigma Global Vision Contemporary line. With a 16.6x zoom ratio covering focal lengths from wide to telephoto, this lens also offers a 1:3 macro ratio.

I like that this lens works in small rooms and outdoors without having to swap lenses. This replaced my two kit lenses. Only issue is the zoom is a little stiff so no fast adjustments or smoove zoom but it doesn't creep when using which is good .

Good price compared to Nikon equivalent

None

Lens is robust and solidly built. Will take awhile to get used to the weight. Have not had opportunity to use it in the field yet, but preliminary tests at home yielded excellent results. Reviews were great for a lens of this zoom span; appears to be a ground breaker.

You can't expect the same performance from a superzoom lens like the Sigma 18-300mm F3.5-6.3 DC Macro OS HSM Contemporary ($579) as you can from a prime lens or a shorter high-quality zoom like Sigma's own 17-70mm F2.8-4 DC Macro OS HSM .
