HI Kostas!
However, I have a question:

What is manual mode, TTL flash? I thought it's either-or.
The camera is set to manual mode for the ambient light exposure. The flash
is set to TTL. I try to set the ambient exposure to just 1-2 stops under
exposed. the TTL flash will (usually) correctly expose the main subject,
and the background is a bit darker, so the subject stand out a bit more.
And while I am at it...
saturation, and sharpness have been tweaked up a bit. I also find that
with digital I have to use a monopod, even at shutter speeds of 1/350 I
have a hard time getting a really crisp image.
You said something about digital acutance thingymabob in another posting.
Isn't the difference caused by the higher magnification? I would have
thought the 1/FL rule, being empirical, applies to the 35mm negative. With
the 200 on the 1.5-factor "neg", you are looking at 1/300, but with the
200 being a heavy lens, I would have thought one is pushing it at that.
I've wondered if one should use the 1/FL rule with cropping DSLRs, or use a
1/F*1.5. Since you are in essence just cropping an image it seems that the
1/FL rule would apply.
What I found with the *ist-D was that I'd get a ghost image just a tiny bit
off of the main image. The explanation I've come up with is that the
acuatance in digital means that the tonal values change very rapidly. I
think that in film shots, the ghost image was not visible because the edges
were not so terribly sharp to begin with. But maybe I'm wrong. At any rate,
I would expect that 1/350 would be equivalent to 1/250 even if you assume
the 1/FL*1.5 rule....

p.s.: Get well soon!
Thanks!
