I was sold on the M5 until I saw the differences between the the M10 and M5 feature lists. The M10 has "Translation Compensation" & "Drift Free Horizon" as well as the dual operator transmitter right out of the box. The M5 offers the option to purchase the dual operator transmitter separately, which seems totally reasonable to me, but the lack of the other 2 options concerns me a bit. How much do "Translation Compensation" & "Drift Free Horizon" add to the Movi's ability to stabilize footage? By purchasing a M5 am I effectively limiting myself to handheld shooting? Will I not be able to use the M5 in high speed circumstances because of the lack of these 2 options? Please forgive my ignorance regarding this subject; I have operated a small steadicam for about 3 years and was bitten by the Movi bug last spring like so many others. I finally have some cash to expend on this great product but I'm worried the M5's lack of highly accurate GPS and high speed frame stabilization (present in the M10 through "Translation Compensation" & "Drift Free Horizon") will be a limiting factor regarding the M5's ability to create as impressive results as its older brother, the M10. I'd appreciate it if someone far more knowledgeable than me could dispell some of my reservation regarding this issue. I'm sure I simply don't understand what "TC" & "DFH" really do. I'm sort of assuming they are higher end options that don't necessarily affect the end product and that the price difference between the M10 and M5 is largely due to the payload difference of "Professional" VS "DSLR" cameras. Thx in advance for your kind response!
