Customer Reviews

Great Product
I spent hours and days reading reviews and comparing features and prices of all zoom lenses on the market for my Canon EOS300D. I wanted a lens replacing my old Canon 18-55 kit lens which is ... well simply a kit lens. I've decided for this Sigma 18-200 all around zoom with OS (optical stabilisation) which is Sigma's version of Canon's IS and Nikon's VR. And I can't be more happy with my decision! OS works like advertised helping me get sharp images even in the bad light conditions and using long focal lengths. Image quality is superb comparing to my old lens. Of course you can't expect Canon "L" lens but who cares for such a price? Build quality is perfect and as a side effect of using quality materials lens is quite heavy. I really recommend this lens for everybody who want solid quality and don't want to change lens every 5 minutes.

Good purchase
Bought this some months ago from a small independent before it was generally available in Nikon fit with the HSM. Purchased to be able to have a lens that I could just fit to my D40 SLR and do away with all the faffing about changing lenses. Having had a previous bad 'dust on the sensor' experience with a previously owned D50 I wanted to be sure that I needed to swap lenses as few times as possible.

Since the day I bought it it has been fitted and never removed as it has suited all the photo opportunities I have encountered.

The 18-55 Kit lens has been in the box ever since and never used - simply no need - apart from size/weight which I will come onto later.

I have been very happy with the image quality the in built OS is a god send at the far end of the zoom range (note the picture does 'jump and judder' for a milli-second while the OS kicks in but this is normal).

If this lens has a down size it is it's size and bulk. Given the optics required to create the zoom range this should not be a surprise but understand this is a heavy and quite sizeable piece of kit.

I mention this because the D40 is marketed by Nikon on the strength of its weight and size - being a very easy to carry SLR - when you fit this lens you lose this advantage.

We are off to Florida shortly and for the theme parks I plan to use the kit lens just to make i that bit easier to carry - any zooming I will do 'post production' with Paint Shop pro.

Other issues - I also sometimes find the zoom ring a bit stiff, thought it might have been faulty at first but this was either down to the newness or I have got used to it.

It comes with everything you need, front and rear caps and a very nice 'petal' type lens hood.

For my money this is very good value when comparing with the Nikon equivalent - it cost just about the same as I paid at the time for my D40 - didn't want to lash out much more than the price of the camera, just for a lens - so settled on this.

Sigma Lens Brilliant and NOT that Heavy !!
Purchased this on impulse as Jessops selling very cheap at the moment about £150 less the the Nikon !
Very impressed with the build quality and has a zoom lock to stop zoom creep altho i don,t think it will happen as zoom quite stiff which brings me to the only negative i can think of ,the zoom is rather stiff hoping it will loosen up a bit but the positive is no zoom creep at all and any angle unlike the Nikon version.
I,ve tested the optics compared to the lens i have at the moment which is the Nikon 18-55mm VR and 55-200mm VR lens, the long end is MUCH sharper then the Nikon 55-200mm VR and provides better contrast as well and at the wide end compares very well to the Nikon 18-55mm VR lens.
Really not that heavy bearing in mind what it covers and seems well balanced either on my D300 or D40.
HSM focusing is quite and quick even in gloomy light and i know that some people are concerned at how slow at the long end the lens is but ive had no problems focusing quickly enough in most conditions.
Summary lens is a complete bargain and you won,t go wrong buying it, build is superb and optical performance very impressive indeed.
Focusing is nice and quick altho the OS is quite noisy esp compared to Nikon VR.
