There will be camera issues with supporting/using this uber wide angle lens.
Majority of flat bed folder cameras cannot be compressed enough to bring a lens of this short focal length to focus at infinity.
~38mm for 4x5
~75mm for 8x10
This would demand/require the front of the flat bed camera to drop out of the len's angle of view on top of being able to compress enough to focus these lenses to infinity.
Then there is the shutter issue. If this lens is in barrel only, even fewer flat bed field folders will be able to use this lens. Granted the exposure aperture will be small allowing the possibility of using the lens cap as the shutter.
Know the majority of view camera users today are light weight flat bed field folder centric.. The scenario of a customer/user of this lens discovering there is no possible way the revised Hypergon can be used on their favorite field folder is a very real problem and could rapidly tarnish the reputation and market acceptance of the revised Hypergon..
In the case of Sinar Norma, no issues at all..
The 5x7 Norma easily compresses to less than 38mm from lens board to ground glass including the Sinar shutter. Flipping the rail clamp around puts the front of the camera completely out of the uber wide angle of view for the Hypergon. Difficulty will be current majority is resistant to monorail cameras for various reasons.
Alternatively, a specialized wide angle camera is made specifically for this Hypergon. The speciality camera could be not a lot more than a box with a Packard shutter or similar, ground glass/film holder rear and the focus could be essentially fixed due to the uber wide angle of the Hypergon.
Curious, how are optical Apodizing filters made? Could a variant of Apodizing be made as an alternative to the common ND center filters used to correct for light fall off of Biogon style wide angle lenses?
