Bellows compensation for 14" lens on 8x10

[Greg Blank]

I did say some times, I use a 150mm as a "Normal" lens. When I do close up work I primarily use a 240 or the 300.

How do you figure that? I suppose you never focus closer than infinity?

Presuming 150mm as a "normal" means a 4x5 format, you must get one heck of a bellows draw using a 300mm for close-ups...

Since I have two cameras I usually use the 8x10 for the three hundred and 240, but both lenses will work on the 4x5.

You can have a look at this web site. I find the section of John A. Cook the easiest one.
