image stabilization which is an absolute must shooting longer low light exposures. This lens replaces my 18-55mm Canon kit lens, and should easily demonstrate the quality.

creep, the sheer weight of this little lens is testament to its high quality.

Certainly not a cheap lens but with a maximum aperture of f1.4 this product read well in lens reviews which I studied before committing to the purchase, I figured there and then the price was worth the expense. And the results did not dissapoint, beautifully sharp images and excellent colour rendition justify the purchase. Ghosting and chromatic abberation appear in the early stages, at least, to be no problem.

As a Canon camera user, I expect a fast auto-focus system and in good light it certainly is fast. However, in low light the Sigma f1.4 is a little slower and tends to 'hunt' a bit more than the Canon lenses. A very well built lens hood ships with the Sigma 50mm f1.4 and has a nice lock to hold it in place. How many years this lock will last we are yet to find out. It also comes with its own padded case. Reviews show the sigma to be a close competitor to the Zeiss 55mm f1.4 'distagon' lens which does not have auto-focus and is more than 5X the price. Never a great fan of Sigma lenses in the past.....I would have no hesitation in recommending this Sigma to serious photographers, available with either Canon or Nikon mounts.

Better Than Any Nikon 50mm Lens – These Sigma ART lenses are superb. There are two aspects of the optics that really matter in a fast lens: sharpness and bokeh and this lens is… Read more

phenomenal on both counts. Yes, it's big and heavy but do you want quite good or amazing? That's what this lens gives you. Tested against my lighter and slightly smaller Nikon 1.8G it's simply in a different league. Don't even think about comparing it with the Nikon 58mm 1.4 for sharpness, it'd be too embarrassing. Yes, it's heavy but it'll still be going strong when I'm long gone. This lens exists to be shot below f2.8. If you don't need or want that then don't bother with this lens. On the other hand if you do need that then this 50mm 1.4 should be the first one you look for. For what it is I think it's great value for money. It's simply flat-out amazing. My only very small complaint is that it needs to have 50 emblazed on it in several places in big letters so that when you also have a 35mm ART in your bag, as I do, you can quickly tell which one is which.
