Digital BW, The Print

Paul's right: given a tripod and film flatness, quite ordinary lenses 
generate remarkable negs. Which brings me to the cheapest solution of 
all. The 6x7 Koni-Omegas are built like armored vehicles, and 
incorporate the Simmons backplate in their separable magazines. The 
backplate moves away from the film plane as the film is advanced, and 
the last centimeter or so of the film advance slide presses it 
FLAT against the film and film plane. And the lenses are at least 
good, and in two instances damn good. (Hexanons). The machines were a 
press standard in the seventies, and are now all over the place for 
$250, usually with the 90mm. I use the twin-lens variant, the 
Koni-Omegaflex, much rarer and a hundred dollars or so more
expensive. 
Scanned with a new Epson 2450 for printing in my 1160, the 6x7 
negatives are very, very satisfying.
