hello,

I have an old Hermagis Portrait lens, Petzval type, marked as Nš 5. I checked that it focus infinity at ~300 mm (12 inches) from image to the Waterhouse stop slot. It is quite big: 8 inches tall and lenses have a bit more than 3 inches diameter. I am planning to build up a wood camera for wet plate with it and my question is: what is the maximum plate size this lens will cover?

Thanks for any insight about it
