Though the same lens on a different format also doesn't change the depth of field does it? My 250mm Fuji lens has the same depth of field on my 8x10 as when I put it on a 4x5 - but then I usually get lost in the math somewhere around here and have to rely on Henning to explain it... :-) > All I know that it is hard enough focusing with a 35mm in an SLR > (manually). It gets harder every year. :) Yep! - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
