Mike did a quick comparison with the K525i vs. the K624i at 12x and to match up the FOV between the two, the K525i needed to be dialed back to high ten low 11x.
Interested to see it myself. Honestly and this is just me but it could be a major complaint of mine. Eyebox sensitivity and FOV are kind of paramount for optical instruments. The Mark 5 is the most recent optic i've used with comparable FOV and also a somewhat tight or unforgiving eyebox i didn't mind it that much but it was noticeable. What's strange to me is that the Gen II razor gets those two things very right, yet remains in a short compact package. Yes the weight is 1lb more, but on a design standpoint it's impressive. All done with a 6x erector as well.
