Bargain Superzoom for Canon
Discussion
I'm NOT saying that this is a good lens - but it could be a useful bargain for somebody on a budget.

Fascinating that the same for Nikon is so much more expensive. Why would that be?

Otherwise the Canon one seems fantastic value! Nikon's own 18-200 is touted as a "walkabout" lens for travelling light. I've been tempted to have a look because it's a very useful range and a lot lighter than a 17-35mm, 70-200mm and a 50mm f/1.4 which would be my normal backbreaking kit (or maybe just the 45mm!).
Given that it's a compromise on quality (and aperture) you Canonites look lucky on this Sigma!

According to the Product Description on Amazon it IS!Amazon link said:
Product Description
Manufacturer's Description
Sigma’s unique OS (Optical Stabiliser) technology
This lens is equipped with Sigma’s own OS function. This function uses two sensors inside the lens to detect vertical and horizontal movement of the camera and works by moving an optical image stabilising lens group to effectively compensate for camera shake. It also automatically detects movement of the camera and compensates for camera shake when shooting moving subjects such as motor sports.
Excellent Optical Performance
A Special Low Dispersion (SLD) lens and three aspherical glass elements provide excellent correction for all types of aberrations and produce a high level of optical performance throughout the entire zoom range. The super multi-layer lens coating reduces flare and ghosting. It also produces an optimum, neutral colour balance.
Close-up photography
This lens has a minimum focusing distance of 45cm (17.7”) throughout the entire zoom range and a maximum magnification of 1:5.3, making it very convenient for taking close-up pictures.
Inner focusing system
An inner focusing system provides high performance and convenience. The non-rotating lens barrel perfectly suits the matched petal-type lens hood (supplied) and circular polarising filters.
Zoom lock switch mechanism
A zoom lock switch mechanism is provided to prevent the lens from creeping due to its own weight.

...and then, following on from that: there never used to be many glass factories in Japan, although now, of course the factories are probably spread all over the far east (The Yanks get all precious because some of their Nikkors are made in Thailand and not Japan, for example, assuming that they'll be inferior - how easily they forget Poole Harbour!).
Who makes Sigma glass for them?

It was surprise that did most of the damage - and as WW2 progressed, US stuff got better whilst Jap stuff didn't. Wake the 'sleeping tiger' at your peril!beano500 said:

The Japanese are the same - they often get 2 versions of the same product, one made in Japan and one made elsewhere (and sold cheaper).beano500 said:

The Nikon one has HSM autofocus (required as otherwise their low end bodies cannot autofocus it). I think that the Canon is just a normal motor (not a USM equivalent). Feel free to check that though as I am not positive that this is one of the lenses that this applies to (there are several in the Sigma range).Gassing Station | Photography & Video | Top of Page | What's New | My Stuff
