I stumbled upon an unused Tokina AT-X Pro 28-70/2.8 for less than 200€ so I pulled the trigger on it.
Beast of a lens, heavy and clunky AK-47 feel to it but has m ore than decent IQ (70mm f/2.8 is dreamy but sharpens nicely @f/4).

Note that there are multiple versions of this lens, mine is Japanese version 2. Typically outside Japan versions 1 and 2 were marketed (correctly) as f/2.6-2.8, then there is a f/2.8 marked international version and finally the SV(which is far less robust and inferior in every aspect). There is also 28-80/2.8 which is nice.

Only thing in common in all sources I could find is that they say to avoid the SV version. Three(or sometimes more!) versions of the original lens are well regarded(albeit there's that "Tokina glow" at the longer end wide open) but basically all sources gave different version as the best one.

Then there is a AT-X 28-70/2.8 WITHOUT the PRO-markings which is the worst of these by far.

Identifying these can be a pain in the ass but versions 1 and 2 can be told apart from the hood. 1 has screw in hood and 2 has bayonet. Of course to make things a bit more confusing there are late model 1s with bayonet hoods.

All-in-all I recommend the lens at that price but would propably buy newest version of Sigma 24-70/2.8 used.

I have one of these Tokinas for sale in the Marketplace now.

That's Japanese version of AT-X Pro II by the looks of it (I bet you knew this).

I looked at the examples 20-40 limited in Pentax K1 Laboratory: appear without vignetting and perfectly usable on the K1. Someone tried and can give confirmation?

But they would be in crop mode, right?

I seem to recall that it doesn't vignette over 24mm.

Very serious vignetting in the pics in that thread, Blade Runner. Can you reconcile them with the pics you saw in the gallery?

Absolutely not ... surely there's been a lot of PP!
