Call me old-fashioned, but I'm thinking of stopping at 68 deg. And I have been looking through an Ethos 13mm for some months now and have a cheapie 80 deg widefield.
Yep, it's the age-old AFOV debate - on again?
What I can say is that what I do see in the field centre of the 13mm Ethos is beautiful! Sure looks like "good glass" to me. But I'm not good enough to pick a difference from the field centre of a Panoptic - so I may stay with Pans?
