I have had an excellent Panasonic DMC G1 for the past 6 years and over time have purchased several wonderful primes (20/1.7; Oly 12/2.0; and a Sigma 60/2.8). However, as a retired Forester who is in the habit of going "walkabout" with a camera, I often long for a macro lens. Now I know that there are several options, but I have noted (and I am aware of the d.o.f. limitations of larger sensors) that there is talk of the yet to be announced Panasonic 30mm/2.8 macro having a greater depth of field than ???. Is there a possibility that this lens will give me a d.o.f. equivalent to that of my ancient Nikon Coolpix 8400's 2/3 (6.6 x 8.8mm) sensor ? (photo below). If not, what's the point of purchasing a "Macro" lens that offers (due to the sensor size) a shallower d.o.f. ?
