I posted a WTB add for a set of bag bellows for my Shen Hao. People brought up the legitimate point that I might be able to use a recessed lens board instead. I am using a 90mm f8 Super Angulon and I shoot mostly nature/landscape but will be shooting some classic New England architecture, old churches, barns etc.
First of all I would love to try a recessed lens board but I'm not sure if I should be looking at the 11 or 19mm recessed boards BUT it seems as if there is absolutely no doubt that the bag bellows would do what I want to do. A recessed lens board would be less expensive and I wouldn't have to swap out the bellows to use the 90mm lens. The bag bellows is more expensive but I would have the potential for a lot more rise, fall and shift-with a 90mm lens I don't really think I need front tilt. One minute I think I should go with the bag bellows and the next minute I think all I'll need is a recessed board.
Even with nature photography I'm wishing for rise an fall to maintain vertical trees.
