The recent discussion about short focal length l.f. lenses has got me to thinking: Wouldn't a retrofocus design reduce the need for a center filter? I would think that because the rear cell would be farther away from the film plane, the law of inverse squares would have less of an effect on the edge brightness. OK, I'm not an optics expert so I'm not sure how covering power would be affected, but I would think that for a situation where not a lot of movements are required, a retrofocus design would (could?) be a good compromise. Opinions?
