I am not going to make any claims to them being stunning, but all the shots in my EPZ pf since Phalaenopsis were taken with the K10D.

I am still getting to grips with it and my digtal workflow is not at its best at the moment due to some hardware issues, but no regrets so far.

I think this is probably the shot I am most happy with to date: http://www.ephotozine.com/gallery/largephoto.cfm?f=77751_1168017392.jpg&background=4

A fair point, I have updated my profile to include location.

Thanks for the pointer about SRS, but I was told elsewhere that the pentax mount had not been released yet.

There is always a chance that they are delayed due to development of a version that exploits the new focus motor mount, but that may be wishful thinking.

Correct.

It was poor English I grant you, but the fact I said Sigma EX is a give away.

I like the look of the new Sigma EX 70mm macro. It is getting some good reviews at the moment, but I don't know when the pentax fitment is going to hit the shelves.
