Variable Shutter for Aaton LTR 7

[Jacob Robinson]

Hi,

I've recently acquired an Aaton LTR 7 and was wondering if it was possible to fit a variable shutter in the LTR to allow flicker free filming at 24fps in 50hz countries?

I know some lights will be fine, my concern is practical lights which will pulse with a 180˚ shutter at 24fps.

Thanks,

Jacob

From the Aaton 7 LTR sales brochure of 1979, there was an optional 188/172 shutter for shooting 50HZ 24fps that you could purchase at the time.

Thanks Brian! Now I need to source one...

Aren't movies in Europe shot with 24fps? I'm confused on why nobody has ever had an issue with this in the past.

I’m from the US so I might be off but I thought this was why a lot of European productions shot 25 fps not 24?

Yes movies always 24fps with 172.8 degree shutter and tv stuff 25fps at 180 degree shutter

I used to shoot with a CP16R, which didn't have a 180 degree shutter, at 25fps, without flicker issues under lights, but TVs had a bent bar, instead of a straight one.

Thats what I thought. Thanks for clarifying.
