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.

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 .

Inconsistent sharpness; Noticeable image distortion; Dim corners

This is a great lens for the money. I bought this as a travel lens for a Canon 7D Mark II and recently took it on a trip to Hawaii. I found I never had to change lenses the entire time. This lens worked great at macro and even better at zoom.

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.

Sigma are continuing to gradually update their lenses to fit into their 'Art', 'Sport' and 'Contemporary' lens lines. This new lens sports a 16.7x zoom range, silent focusing and optical stabilisation.

Good optical performance for a super zoom lens; Well built; Lightweight; Compact; Optical stabiliser; Compatible with Sigma USB dock; Good value

Loose manual focusing action with no full-time manual override

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 .

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.

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.

This lens replaced a Sigma 18-250 mm telephoto zoom lens. The new lens is used with a Canon SL1. My first tests with the lens indicated that the image quality is excellent, except at 300 mm, at which image focus is slightly soft.

Best at this price . Results are amazing
