In past I had the 17-40, 16-35 I & II, Tokina 16-28 2.8 ATX Pro and now finally the Tokina 17 3.5 ATX Pro.
Does anyone know which UWA lens is the sharpest up till the corners at lowest aperture ?
For my lens it's from f11-f16 (more direction f16).
I know the common problem is that UWA's are not sharp in the corners untill you stop down a lot.
As I take pics in dark abandonned buildings with it we have a time scheme, so time is cruxial, how higher the aperture how longer it takes to take 3 hdr pics.
Sometimes it takes 30 sec per pic...
We try to keep our iso's as low as possible. Sometimes in dark circumstances I go to Iso 400 but not more, evenwith a 6D i see noise then in my hdr's.
This is now the best lens I tested over all of the above, also lightweight, compact and no flare.
