I don't want to give anybody the wrong impression about this lens. It is possible that some readers might be under the erroneous impression that the lens focusses quickly. That is not the case. It is really quite slow. I hope that is now clear.

What you need is the Sigma KAF 50-200mm. It has built-in AF, and will therefore convert any Pentax K-mount MF body to AF.
It's good for doing upper-body training as it's not light (it takes three batteries), and the AF takes a few minutes to lock on, but apart from that (and the poor optical quality) it's a fine lens in the best Sigma tradition.

PS: I forgot to mention, it comes with a leather case. That should be the clincher.

My advice is not to pay much money for this lens.

It's the quickest way to clear the card.

Bright daylight only, though. You wouldn't want to try and focus at f12 in dim light.

So your friend certainly has a macro lens. And a damn good one.

I would prefer more range at the low ISO end than the high end. 50 would be good, but 100 is better than 200.
As long as 400 is very good, and 800 useable, 99% of my photography will be covered.
And as for the 1%, there's always the 50mm 1:1.2.

Apparently Japan has been delayed to ensure that Europe and North America get their cameras on schedule. I suspect that Pentax have been pleasantly surpprised at the level of interest in the K10D, and the number of advance orders.

Sorry George,
Could you please clarify whether the Sigma lens that you refer to focuses quickly or slowly, I'm not sure you've quite got your point across.

Please excuse my vagueness on this issue, and I am grateful for the opportunity to make myself abundantly clear:
Those who don't believe that the 50-200 is the not the fastest focussing lens on the planet are not incorrect according to those who are ill-informed.
