Hi Rob ... I'll try with the t'pod tomorrow and use a smaller aperture. Never thought about focus bracketing. Not a bad idea ;-))
You knew I'd been thinking about a DSLR for a while and that it was just a matter of time before I'd get one. My little Sony had a tripod mishap, and the price on the DS was very low, so it seemed like the perfect time to make the move. I'll be able to get a few dollars for the Sony to offset the DS, which made the deal even more appealing. Exposure count? Not much ... only about 400 or so, although almost 100 of those were made just to exercise a sticky aperture on a K-mount lens. Plans are to make a few more exposures tomorrow - maybe eight or ten ;-)) Shel > [Original Message] > From: Rob Studdert > > I'm hoping someone (perhaps Paul) can offer a suggestion as to what aperture and > > focus point might best provide some sharper results.

BTW what's your exposure count so far?
