Something like this should of been made a year ago, at least. Totally simple design, just chop an adapter in half, screw in a variable ND in the middle, put it back together....done. Just a question of how good the Vari ND is, and at $99 it's a worry, but since it doesn't have to be a huge 77mm+ one, it might be ok.
with HolyManta you can shoot with no ND if wanted. Only thing is HolyManta is triple the price but its done right.
If they'd put aperture and nd...and a good focal reducer inside, make a eos/m43, then I'd be impressed !
ideal does not exist :-) but if you want variable ND it can be option. Requires testing, of course.
this adapter is missing a deal breaking feature. Theres no way shoot without ND. You have to carry an extra no filter adapter. feels like they didn't think this through.
