    Help with compact 30/32mm Alpha Choice

    I realize that I'm not certain exactly what "[more] uniform" would mean here, in contrast to the variation in Swarovision etc. Does a classic design like those decades ago involve a simple (linear?) gradual increase of pincushioning toward the field edge, or... ?

    Help with compact 30/32mm Alpha Choice

    So then we get into whether "flat field" means no curvature or just how little, and how little pincushioning will suffice (and whether it's uniform or more complex), making it hard to stay focused on the point that designs like Swarovision carried these trends arguably too far, and for some...

    Saying that BLTs and Clubs are both "sandwiches with bacon" doesn't preclude sandwiches without bacon. I just mentioned two characteristics UV and SLC have in common, versus (say) the OP's ELSV. Of the two, it's pincushioning that would affect AFOV, but I never quite know what anyone means by...

    Help with compact 30/32mm Alpha Choice

    This list immediately makes me think of Zeiss FL 32, which can still sometimes be found in near-new condition, although UVHD+ could also work if you find it sufficiently "sharp" in the center, and its view is more similar to your SLC in overall character. Also the MeoStar mentioned by Gijs...
