Ed,

I recall you saying that many pros were using Sony DSLRs, with
full-frame (24 Mpix) sensors. This would be the moral equivalent of
35mm Kodachrome.

What are the pros using to replace 2-1/4 by 2-1/4 (Hassy), 4x5, 8x10,
and so on up?

I'd hazard that digital may be approaching 2.25x2.25, but the larger
negatives are still out of reach.

Thanks,

Joe Gwinn
