Is that physically even possible?
Dunno. That’s beyond even my armchair lens designer pay grade. There’d be thousands of experts on dpreview able to give you their definitive opinion, though...


Too much Oly gear.
Panasonic 12-32, 12-35, 15. Laowa 7.5.
Assorted legacy lenses, plus a Fuji X70 & a Sony A7S.
