Hi DrDespair
I still use the ist ds and it is quite OK in good light and with TTL flash.
The ds had a better vf and fi than the dl
But here are 2 shots (3000 by 2000 jpgs with exif) showing where it is troubled.
This one at dusk last week with the SMC Pentax-M 1:2.8 40mm

This one today with the SMC Pentax 1:2 55mm (I should have taken the XR Rikenon 1:1.4 50mm)
You can see that I am snookered at iso 800 and 1/45th to 1/60th with the lenses down one stop.

Anyway I got some good ones of the kids in that light with the 55mm. (I don't put the kids up on public internet)
So I mentioned all this the wife and let slip something about the Pentax K-01.
Next thing there not just one, but 2 black tie dinner functions placed on my desk waiting for checks.
That blows the K-01 budget, I get snookered every time!
