what if i stack 2 1.33x anamorphic adapters and a bmpcc speedboster ?

[geppoitaly]

hi what the proportion for 4:3? 1.33x1.33x1.33 ? and why if i put 2.40:1 proportion the footage seems too high? are the adapters not 1.33x ? slr magic and ag la 7200

and why if i cross the adapters the image is perfect and as frontal speedbooster not like wide adapters?

p.s. i can autofocus on camera with this adapters.

Stacking two 1.33x anamorphic adapters will result in a 1.77x anamorphic adapter.  This is close to the ideal squeeze of 1.79x that you would want to convert 4:3 to 2.39:1 .  A Speed Booster will shorten the focal length.

thank you mr caldwell, then the formula is right... 1.33x1.33x1.33

why i must compress more vertical image after 2,40:1 in potplayer (not real 1.33x adapter ratios ?) ?

and yes i know/have your speed booster (shorten....) but why if i cross and not stack (+) two anamorphic adapter the image is perfectly 4:3 but  is more crisp than a wide angle adapter?

why no one make dual anamorphic adapter with single focus? if i stack slr magic with isco anamorphot the image is more sharp and i don't lose autofocus ! why ? thank you in advance
