I'm aware that the Grandagon specs are a bit underrated and the Nikkor specs are a bit overrated so I suspect both are pretty close to the same. I'm sure I can find center filters that will work well enough for both. As long as the lens covers sharply to the corners not much else matters to me in this focal length on 8x10. Size and weight aren't concerns either since the camera is a Toyo 810G. Let's skip the 110mm SSXL due to cost.
Which lens would you choose and why?
EDIT: I hope to be making mural-sized prints several feet wide so sharpness is very important to me. I'll be using a Rodagon-G or G-Componon enlarging lens.
