That neck looks weird. I guess you could call it a new version but really its a old lens with a spacer as far as I can tell.

The optics is a new project.

The optics is a new project.

I'll take your word for that just now, it just looks suspicious to me.

It has 22 elements in 16 groups, including one FLD and four SLD elements. The old version 21 elements in 15 groups, with four SLD elements. Optically the old one was pretty good but with poor IS when it came out. The new one can take a tripod ring, which is a plus over the old. It uses a stepping motor for AF.
