The OS version of the 150-500 has just been announced by Sigma link
Availability is stated as April 23rd. I'm interested to see if they announce the OS version of the 120-400 as well, as it has been unavailable in Pentax mount for a while now and SRS said the next deliveries were due in April, looks promising.
I also expect that we shall see the 100-300 f4.0 EX and maybe even some of the other big guns arrive soon with HSM and OS for Pentax mount, as it would seem that Sigma are rationalising their range to have HSM & OS as standard across all mounts.
I know that SR is available in body, but in lens OS is slightly more effective and you do see the stabilising effect in the viewfinder.
In the continued absence of long telephoto zooms from Pentax themselves, these Sigmas are our only option and it's good to see that at last we have the same opportunities as our Nikonian and Canonite friends who choose to go third party.

G'Day Lance!
That's quite a saga. It appears from your description that it is AF that is in issue here, not focus per se were one to do that manually?
Also (knowing you had a K10 and K20), did you discover shims in those bodies as well?
It has nothing to do with AF. The A50mm f1.2 is a manual focus lens. G'Day Lance!

The discrepancy is due to the focussing screen not precisely correlating to the sensor plane (which is not adjustable via the AF micro-adjustment).
It's actually quite common, but most users don't notice as the standard screen doesn't have sufficient "snap" and also most lenses are quite slow in comparison to an f1.2! You do need a very shallow DOF setup to notice it, a long fast telephoto is a good lens to use.
Most SLR's have some form of focusing screen positional adjustment, usually via shims. My K10D was slightly out on manual focus and needed adjustment which was done by Pentax service under warranty.

James from Pentax will be there with goodies for all to try.
Before anyone asks - I doubt if he will have a 645D!

Roll film available at 7dayshop.com, wide choice at good prices and fresh stock.
They also do processing, but I've never used them. I always used The Darkroom in Cheltenham, top class, fast and reasonable.

I tried several Tamrons (and Sigmas) at SRS to find the best samples and try them against the 12-24 as I am very price conscious (tight! :wink.
The net result was I bought a s/h Samsung as it was SO much better than even the best of the others. The extra £'s was definitely worth it, the loss of the 2mm was of no interest to me as there is just a bit too much perspective stretch at the very wide end, I just wanted a bit more below the 17mm of the 17-70, 12mm is more than sufficient.
I've also compared the Samsung with a couple of Pentax DA 12-24's and found no discernible optical or physical differences and the coating colours look exactly the same, the difference is purely cosmetic and the Samsung doesn't have the same lens ID chip, which means that the auto CA & distortion features (JPEG only) on a K-7 (and K-x?) don't function, but that's the same with the Tamron and Sigma.
The only 10-24 that comes anywhere near the Pentax is the Nikon one and that won't fit a Pentax!

I'm sure SRS (Chris) would match that price , and if you quote your forum name, there's no carriage charge.

Congratulations Matt. I hope you have lots of hours of pleasure from it.
I'll keep on saving and hope the K-8 (?) is announced soon. Fat chance.
The problem is that it will be at premium prices for at least 6 months and subject to the usual risk of early adopter issues.
I'm a great believer in buying an established model towards the end of it's production cycle.
