[QUOTE=Mal Paso;1713451]How much bellows draw?]
Malpaso,
Measured bellows draw is Fifty-three Inches, so calculated Bellows draw factor is TWO STOPS for this close-up.
1000mm F16 Apo Ronar Wolfe Configuration Close Up Looks Good by Nokton48, on Flickr
This is very close to what Mr. Wolfe was using out in the field. A standard sized 8x10 Norma Bellows, three Norma Auxiliary Standards (I have another one coming). Three Norma 4x5 standard Bellows. The Compendium Hood is a Norma Tapered 4x5 Bellows. Viewing through the lens image looks really good and sharp. The two C40's provide ROCK SOLID support even in strong wind. Tripods may be weighted down in the field.
When I'm ready I will expose some test film. Sure does look great on the ground glass. Typical Apo Ronar optical performance. BTW my working aperture full open is F32. I'm be exposing with multiple Broncolor pops which works OK for B&W. I think I'll use 8x10 HP5+ for maximum speed. Then contact print.
