The cartridges are indexed for 160 ISO indoors, 100 ISO outdoors. To compensate, increase your aperture by 1/2 of one f/stop. If you have manual exposure override this is easy. Or, your camera may have a +/- 1/2 to 1 f/stop correction button. Either way, adjust the f/stop 1/2 a stop. This is done to allow a little more light into the camera, so choose a 1/2 stop LOWER number on your lens, as the lower the f/stop the more light coming into the lens.

Ektachrome VNF 7240 film will index in most Super 8mm cameras to ASA 160, which is 22% higher than the actual ASA of 125, or approximately 1/4th of an F-Stop....not enought to worry about that much. For indoor available light filming I highly recommend a good XL (existing light) Super 8mm camera, and/or bounce a movie light off a white ceiling or projection screen if you don't have a white ceiling.....as this will give you some more pull in your exposures as far as correct illumination goes.

---> All the XL cameras you mention should expose this film at ASA 160, which IF you have sufficient light, you'll be okay in your exposures. If the light is very low, you could have the film "Push" processed which will boost it up from the actual ASA 125 to ASA(EI) 250 for a "1-Stop Push" with some increase in contrast and grain. The film can also be slightly pushed by myself as I manually process, so I can do a 1/2-Stop Push, thus ASA(EI) 190 approximately. This filmstock is not an exact match for the former Ektachrome 160, but it was the only thing Kodak currently makes to fit the need.

---> I do wish to add here......keep in mind...IF not exposing the filmstock for anywhere from a day to up to 3 months keep it refridgerated (remove 1 hour prior to use for warm up time), and freeze it IF you're not using it for anytime earlier than 3 months. After exposure have the film processed promptly, and if you can't afford to have it processed promptly, then place it into a ziplock bag and keep it refridgerated....and get it processed as soon as you can. VNF film is very prone to a magenta (pink) color bias and unless these rules of thumb here are adherred to, the film will yield magenta shifting that can be quite annoyable. It is considered a "professional" filmstock by Kodak, and these are their parameters for all their professional filmstocks, negative or reversal. Various labs offer push processing up to 2-Stops over if you require it. As for which camera to use....select the one of the ones you have, that has the largest lens opening (smallest F-Stop number...e.g F/1.1 or F/1.2), as that one will have more exposure capability in lower light.

Good luck and happy filmmaking!
Best wishes,
