Lens coverage figures are often given for f/22 at infinity. To focus at 1:1, we need twice the focal length.

Does this mean that we get a circle of coverage whose diameter is twice the stated infinity coverage ?

So while a 180mm Fujinon A is said to give 252mm coverage at infinity and f/22, will it give 404mm at f/22, when focused at 1:1 ? If that is the case, would it not make a good closeup lens for 8x10 ?
