Greetings all! This may be a crazy question but has anyone converted a old 1/2 plate camera to accept modern 5x7 holders? It appears that the 1/2 plate dimension is very close to 5x7 film so perhaps if one had a 5x7 back and adapted it to fit where the old 1/2 plate back was it might be a cheap way to get into 5x7? I know, I know. The older plate cameras didn't have alot of movements but they appear to be the ancestors of the more recent age of field cameras. Any light to be brought to this topic would be helpful. Thanks!
