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.

I just checked, here is a comparison between the 16-35 f4L IS with the 16-35 II (but I knew this lens was not sharp in the corners anyway so no real comparison):

Why not a Samyang/Rokinon prime? My 24mm is super sharp in the corners at ƒ2, and the 14mm ƒ2.8 is said to be really sharp in the corners as well?

The EF 24 f/2.8L IS USM? DLA on the 6D is about f/10 or f/11. You can sharpen up your entire photo by opening up a bit from f/16. At 24mm & f/11, focus at 6', and everything from 3' to infinity should be in focus. Take advantage of hyperfocal distance to avoid those narrower apertures.

Judging from these figures, Samyang 14mm blows both 16-35 f2.8 II and 16-35 f4 out of the water - as long as you can live with its much stronger (and non-linear) barrel distortion:

http://www.photozone.d​e …77-canon_1635_4is?start=1 (external link)

At f2.8, it's 11% sharper than 16-35 f2.8 II @ 16mm at the centre, and whopping 76% sharper in the corners. At f4, it's 5% sharper than 16-35 f4 @ 16mm at the centre, and 18% sharper in the corners.

Heya,

Some manual primes are sharper. Look to Samyang/Rokinon 14mm & 24mm (shooting at F2.8 and F2).

Very best,

Not sure I'd agree with that. (external link) Unless you mean specifically at 14mm, then yes, the Samyang blows both of them away.

I heard the Samyang has quit a bit of sample variation. That might explain the difference. But lenstip review of Samyang agrees with photozone one.
