Does anyone know the ISO speed of Canon XM2?

Thank you very much!

Thanks a lot!

The 508 ZoomMaster has not the possibility of change the angle, the version called "Cine" can do this (but I'm quite sure that the two light meter have the same electronics and that this function is only software!).

I'll use yours trick in my future works!

In the instruction manual of of my light meter (L508 Zoom Master), I read that in cine mode the exposure value are showed for standard shutter open angle of 180°.

If I need different angle I have to change ISO (+1/3 for 220° and -1/3 for 160°).

I think that this is quite OK for 220 angle: (220/180)=1.22 time the 180° exposure,

that is about log2(1.22)=0.29----->+(0.86/3) instead of +(1/3).

But for 160° I have (160/180)=0.88 time the 180° exposure,

that is log2(0.88)=-0.17---->-(0.5/3) instead of -(1/3)!!!!

log2(x) means base 2 log.

Is that correct or I made some mistake?

Thanks

Hi Matt

I have the same problem, I need to shoot a scene in a movie theater, in super8 (Kodak Tri-X 7278, B&W 160ISO) and video miniDV.

I found out that with the 35mm projector there wasn't enought light to expose film, and the image on miniDv at maximum aperture with 1/50'' was too dark.

So I think I'm going to lit characters with tungsten lamps (key ligth, fill light, back ligth and just some effect light) and use hands or whatelse for the flickering purpose.

I'm new in cinematography, so this is all I can say about your problem.

I hope this can help you, if you solved your problem, let me know, I'm shooting the next month, so any suggestion is wellcome

Thomas
