If my eyes let me down, I find the green hexagon is a pretty accurate indication of focus with my K-r and manual lenses. Also 'catch in focus' works very well too.

I'd agree with the zoom creep, to an extent, but not with anything else. My Pentax 18-250mm is a terrific lens - you must have a duff copy.

Cheers everyone.

I think I'm clear now - no HSM in Pentax mount with the f4-5.6!

I thought that was the case, but there are so many advertised on Ebay and in specialist camera shops with HSM that I thought I must be missing something.

Thanks Bill

I did look on other threads first and the one you refer to is more about the fact that one was for Nikon and the other Pentax plus the merits (or otherwise) of a certain retailer.

I'm not too fussed about HSM, just wanted to confirm the used price of the lens and wasn't sure if there was an older non-HSM model and a newer one with HSM as there are so many for sale 'with HSM; even though it seems that they aren't.

Someone on Ebay had one for sale earlier described as HSM. I sent him a message and he was adamant it had HSM and was therefore worth more.

Not just me who is confused, it seems.

Thanks again

A little confused with the Sigma 10-20mm and HSM. I've seen plenty of adverts (Ebay and camera shops) where the 10-20mm f4-5.6 for Pentax is described as having HSM. My understanding from the forum is that the Pentax f4-5.6 version isn't available with HSM, just the f3.5.

Are all the adverts wrong or is there a more recent HSM version and, if so, how can you tell?

Don't have a Facebook page myself, mainly for the reasons outlined above, but it's worth it's weight in gold for my son's business. We estimate around 80% of his work this month has come via Facebook, either directly or indirectly.
