Also don't forget this one: http://www.letsgodigital.org/en/1042...hoto_apo_lens/

-> on a 4/3 camera or (Nikon D2x) it has the equivalent field of view to 600mm to 1600mm!!!

I'm only disappointed they don't have HSM. I found it curious they made another OS lens without it.

I don't think Sigma has ever put HSM in a non-EX lens.

I think you're right - but it just seems odd - obviousl OS is more costly to implememnt than HSM (I'm basing this on the fact that only 2 lenses have OS I think while plenty have HSM) - So, from a product standpoint if you're going to incur the bigger OS cost, I would think you'd also want to incur the focus cost.

Heck, to some users (myself being one) - fast focusing is at least a important (OK to me i t's infinitely more important) than stabalization.

Yeah, USM/HSM is a must for me... Long live fast and silent focusing!

Down with in-lens antishake!

It's not really the fast and silent which is critical - IMO the full-time AF manual overide of the HSM is more important...
At least in the single-shot AF mode one can quickly overide the focus when the camera err on the wrong area!

IMO we're relatively a small picky bunch (and we have the specialized EX'es already) - This all-purpose 1-lens solution will sell like a hot cake considering there's no alternative in the Canon's line up or if it can seriously undercut the 18-200VR in price (don't know if that one has AF-S either)

The Olympus crowd will be doubly rejoice too to have a 36-400mm OS if this lens ever come out in their 4/3 mount!

I agree, it looks brilliant.

They will have the Canon market all to themselves, and if their optics can come close to the Nikon (which on recent form seems very likely) then they will take a good chunk of the Nikon market too.

4/3 is also wide open as you say.

For me personally though, I'd rather have the HSM than the OS.

Nikon can't seem to manufacturer the Nikkor 18-200mm VR fast enough.

You'll find a number of posts in the Nikon DSLR and Lenses forums from users trying to find one (without being gouged by dealers trying to sell them for more than list), getting on waiting lists, etc.

Nikon seriously underestimated demand for that lens from all outward appearances.
