I am very new to large format and have a Speed Graphic with 127mm Extar lens. I am looking for a lens about 240mm to start to round out the system. As I may m ove to 8x10 at some time I was thinking about considering a lens for an 8x10 and using them on the 4x5 as well. Is there any problem doing this, such as the ex tra large image circle reflecting aroaund the camera and washing out the image?

What lenses would you recommend for between 200 and 250mm for my 4x5 camera?
