Over the last year or so, Sigma have gradually been updating their lenses to fit into their 'Art', 'Sport' and 'Contemporary' lens lines. The 18-200mm range is popular amongst those who own a camera with an APS-C sensor and wish to travel light, with the convenience of a large 11.1x zoom range.

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

Sloppy manual focusing action with no full-time manual override; CA levels at 18mm when stopped down

All-in-one super-zoom lenses are all classically huge and heavy. Made to do everything and be a master at nothing, these extremely wide focal length lenses have historically only offered only decent image quality.

Very practical for travel, children and, in my case (I have two wide angles), using it as telephoto. The lens is very well built, but the focus ring is a little loose. Sharpness is pretty good if you stop down, but wide open could be better.

The perfect lens does not exist. There is no lens that covers an extreme range of focal lengths, has an ultra-wide aperture, has incredible build quality but remains small and light, has amazing image quality at all available settings – and is inexpensive.

I bought it used in almost new condition. I needed a go around lens to take with me on a 2 weeks trip to Europe. I shoot with Sigma SD14 DSLR and own 6 different lenses by Sigma to go with it. This one easily replaces 3 of them. So I don't have to carry extra weight.

i love this lens, i used one for 3 years, full time, 5 days a week and have only just replaced it for the updated model with minor upgrades. it is robust, very well built, and even survives the most cringing of impacts.

Easy to use; Build quality; Battery life

Sigmas 18-200mm objektiv är en perfekt lins till amatörfotografen som inte har den största plånboken. Både Nikon och Tamron gör 18-200 objektiv men jag tycker Sigma verkar bäst (utan att provat Nikon eller Tamrons).

Både vidvinkel på 18mm och telezoom på 200 mm i samma objektiv; Detta gör så du aldrig behöver byta objektiv; Många Nikonfotografer använder oftast både 18-55 och 55-200 men jag tycker detta är ett bättre alternativ även fast det blir lite dyrare än att köpa ett 55-200.

Har använt det här objektivet i en månad ungefär så jag har inte hittat några nackdelar och på ett objektiv är det inte så mycket att utforska så jag tror inte att jag kommer hitta några stora nackdelar; Det enda är att vid 200mm zoom så är största bländaren F/6,3 vilket minskar ljusinsläppet en hel

Yes, I would recommend this to a friend

I recently returned from a trip to NYC.I used the lens non-stop during the trip.I never had any complaints and still don't to this day.It is a GREAT lens for the money. Are there better lenses on the market, of course, but they are not under 400 dollars.I in no way can justify spending nearly double...
