30mm clarification

Hi:

Sigma indicates there is no HSM version for Pentax. In my B&H order for the lens, the description says HSM (though that is not shown on the main page). I saw that the "other" guys actually show HSM on the barrel, so apparently they are confused as well :-) You both have the same manufacturer number 300-109.

Finally, EX is not shown on the barrel of this lens but is on another EX lens I had.

So, is it really EX?

I've sent an email to cancel my B&H order, however I think I will contact CS to see if I can keep it.

Hi Chuck:

Thanks for the reply. The description/photos for the Pentax version is inaccurate on the two major webpages. That's not unusual in cyberland, though.

Even the Sigma page you pasted has extra clarification about the Sony/Minolta version...

I have an order in :-)

Just to finish up...

I emailed CS yesteday to cancel the back-order for the lens (filter already shipping, which was desired) , but this morning called directly to have my email ignored and still keep the back-order. Phone person said he would put a note in my order to keep the lens.

3 hours later (just now) I got an email saying my back-order was canceled :-(

I just re-ordered it, however.
