Hi there,

I've just got hold of a s800. I'm wanting to use it with an incident light meter but I'm not exactly sure how to measure it.

It didnt come with the instruction manual so I'm not exactly sure what shutter size to meter it for. And also, I heard that the reflex design takes a little bit of light away so I would have to compensate anyway.

If anyone knows what to set my lightmeter up as to get the best exposure possible with the s800 that would be really appreciated.

Also, Is there any (except for the fps difference) picture quality difference between the s800, 801 and professional? I'm assuming not as they have the same lens.

Cheers,

unfortunately it doesn't tell the shutter-angle, I guess 180... I'd start tests with 1/3 stop compensation for prism light-loss...

Thanks Jeff,

Do you know how much I will have to compensate for with the reflex prism?

Can I get away with using 1/30 for 18fps (my meter only does 1/50 or 1/30) or will I have to compensate with exposure if shooting reversal?

Thanks

An extra half stop open usually does it with the Nizo's

18fps with 170 shutter-angle would be 1/38...

If you can do 1/60 on your meter I'd go for this, this gives a little more than a 1/3 stop compensation...so you should be fine...

or will I have to compensate with exposure if shooting reversal?


do you mean using a reversalstock? Normaly you expose it as usual, be aware that it hasn't the latitude of a neg. I prefer to underexpose slightly colorreversal, it looks more saturated, but that's just my taste...and bright hightlights can go very bright on colorreversal...

sorry my calculation went wrong :D , better to use 1/50, that makes a little less than 1/3 stop compensation
