17-85 vs 15-85
Apr 18, 2012

Hi,

I used to have the Canon EF-S 17-85 USM lens, but it broke (ribbon cable inside wore away with zooming, not an uncommon problem unfortunately).

I replaced it with a Tamron 17-270 lens as a bit of a hurried purchase as I was about to go on holiday. It's a useful lens, but I don't find the image quality as good as the Canon 17-85, plus the focussing is too slow and inaccurate for my liking.

I decided to just go and buy another 17-85 lens, but saw there's now a 15-85 lens that has 2 additional elements, and may arguably have better image quality but is quite a bit more expensive.

I'm not too fussed about the extra 2mm as I have a 10-24mm lens but I can see the benefit.

Just wondering if anyone has any concrete comparisons or views.

Thanks,
