Ah, such a little thing, but so simple when put that way. (Can I plead loss of
mental facility due to advanced age?) Haven't given f-stop relationships much
thought for years -- actually since filter use on my Retina 1A in Korea in 1953
and my Miranda F in Thailand in 1968. (The Miranda drove me to a Pen FT in
1969.) I just select f-stop or shutter speed for the intended purpose, compose
it, preview it and if it looks good to me, shoot it. That's what Olympus' TTL
metering and DOF previewing will do for you. ;o) Thank you, Maitani.
