I wonder if anyone can offer a solution to calculate the increase of coverage at F32/f45 etc as a percent or in real mm terms when the f22 coverage is known. Nikon literature indicates coverage wide open and at f22. Can we deduce that the increase for each f stop is linear? If this is the case then the Nikkor 210W at F45 would have just enough image circle for 8x10 without movements.
