In the same Sigma Global Vision programme, the 120-300/2.8 surfaces again too. A previous version was announced at Photokina in 2010 as well, but contrary to initial rumours this was never made in Pentax mount. I wonder what Sigma's take on this new "vision" is in terms of lens mounts, hoping they'll include Pentax.
I have little hope to find out more at Photokina though. I tried to find out about the previous 120-300/2.8 at the fair two years ago, but I could not find a single person on the Sigma stand that seemed to know about this. Most were just pretty hostesses whose talents did not include extensive product knowledge, quite different from the knowledgeable (mostly) men at the Pentax stand... I might try asking again around at Sigma this year anyway... After all, even if they didn't have much to say, the girls were nice to talk to...
