As with the 24mm Sigma, it'll make you want to replace all your lenses!

Oh. My. Gawd.
To say that this lens is sharp is an understatement. It will make every other lens that you own look soft - if it's not another Sigma Art series that is. It is everything you've read in the reviews and more.
It is sharp across the frame even at f/1.4 but of course at that wide an aperture there is quite a lot of vignetting. This goes away nearly completely at f/2 and it's gone altogether at f/2.5. Aside from sharpness, the colour and contrast is just astounding. As a comparison, I have a Canon 16-35 f/4 IS which I bought for my other half which is no slouch as I'm sure you're aware. To be honest, I wasn't expecting this to be better than the Canon as the Canon is a great lens, but it is. Oh my goodness it is.
At f/1.4 the Sigma is sharper at the edge / corner than the Canon is at f/4(!) and by f/4 it's in a totally different league both in terms of vignette, sharpness, detail and contrast. In fact I've only seen one other lens that's as good as this and that's the Sigma 24mm f/1.4 Art, which I bought before buying this one and is in fact the reason I bought this one.
Bottom line, if you're looking for a 35mm lens to do landscape photography at f/8 or greater then get the Canon 16-35mm f/4 IS as that's a superb lens - far, far better than my 17-40, but... if you're looking for a 35mm lens that you can use at large apertures then there really is no competition. The Canon 35mm f/1.4 is not as good as this wide open. Not even close. At f/1.4 there is no other 35mm lens that I'd buy. Period.
