My widest lens is a 90mm. Furthermore, it's my least favorite. My most often used lens tends to be my 30mm f9 nikkor. Toho makes an eccentric lens board that is supposed to make life easier; however, I would say that 90mm is likely the widest lens that's useable on the toho. However, I love the sub three pound weight of the toho. Yes, I've made it lighter by following kerry thalmann's suggestions.
that should be 300mm.
30mm lenses wouldn't cover.
My widest LF lens is a 55mm Apo Grandagon. It currently gets the most use (about 60%). I also have a 65mm, a 90 mm and a 110mm. 55mm thru 110mm are the focal lengths l use 90% of the time.
I also have a 150mm, a 180mm and a 300mm.
My longest LF lens is a 600 mm Apo Ronar (forget that one on both the Shen-Hao and the Toho).
I am also looking lustfully at the 45mm and 35mm Apo Grandagons.
How much movement do you get with the 55mm on a shen hao 4x5?
Here are the Rodenstock coverage and lens movement numbers for the 55mm lens.
All numbers below are for a Working Aperture of f/22:
Angle of View is 110 degrees
Image Circle is 163mm Ø at 1:Infinity
Shift Limits for 4" x 5" are 7mm and 5mm
Shift Limits for 6cm x 12cm are 30mm and 19mm
These are the two formats I use the most on the Shen-Hao. The Shen-Hao movement capability exceeds the coverage capability of the 55 mm lens for both of these formats.
I have not yet run into a perspective control situation with the 55mm lens where I was coverage limited. When I do, I will switch to my 65mm Super Angulon.
