I'm looking for a wide angle lens to complement my 18-55mm and 50-200mm Pentax lenses. A zoom would be nice but not essential.

I assume I could go for the System KB DA 10-17mm but I see there is also a System 67 series of lenses. What are they for?

Alternatively, are there other manufacturers I should consider?

Thanks for any info.

I've now tested my Metz CL-45 with the K10D. I've lost TTL mode which is a shame but the Metz has a mode where it does it's own sensing so if I dial in the ISO and aperture, it sorts the rest out. It calls this 'auto' mode and this seems to work perfectly still.

It also has various manual modes where you just adjust the camera accordingly so they're going to be OK.

It's a shame to lose TTL and P-TTL seems like a waste of time to me but at least I can still use my favourite flash.

This is encouraging. With all the photo mags being full of Nikon, Canon and bloody Photoshop, it's nice to see some others using Pentax DSLRs with Linux.

I aim to get a K10D in a couple of weeks and I'll be very interested to see how the RAW tools cope with the new format.
