Sigma 10-20mm - question about versions

[Patch]

I see that this lens comes in two versions - the f/3.5 and the f/4-5.6. Is the difference in performance for the fixed aperture of 3.5 worth the price difference of $100+? I know the lower aperture is better for low light, and some of our shots will be indoors, but the lens will mostly be used in daylight for landscapes and architecture. I've actually read that the f/4-5.6 is sharper despite the lower price, but that was from just one source. Has anyone used them both? Thanks.

Great Article. Not much difference between the two based on the price difference. LOL
