But, it DOES have an effective aperture of f/16 with the graduated filter in place. As to the first, yes, Zeiss does most strongly recommend the use of the graduated filter -- otherwise, you encounter the light fall-off so prominent in all of the Heliar shots I've seen to date, and in Godfrey's Hologon shots. I do agree, of course, that the next round of shots should be with the Hologon with filter and the Heliar at f/8. That would be as fair a test as could be arranged under these conditions.
