Using a digital camera as light meter for medium format film

The Sekonic L-208 I had used only one 2032 battery

You're absolutely right.. I must have mixed the batteries up with something else.. But it sure now makes me wonder why I keep two LR44's at hand for when the batteries would die..

ISO is a standard and that's what every Nikon and Canon DSLR that I've owned has been calibrated to. Think about it, if it were calibrated to a different standard we couldn't use a flash meter with it or a spot meter. I use a flash meter with my digital almost every day and it works perfectly.

The ISO standards for light meters for film speed and digital ISO are calculated differently and don't bear a great deal of resemblance to each other, as are the film and digital sensor ISO standards. What the OP proposes can work, but you'll have to test. But for critical work you have to test if you use a film ISO calibrated meter (12% reflectance) and you or the film manufacturer assume 18% reflectance. Any light meter is useful if it is precise and accurate and you know how to use it with your materials, but the further its basic settings are from the standard, the more work you need to do to establish the relationship between the readings and what you should do.

I do exactly what you have asked, sony rx100 for my bronica shots. It's a pain even with such a small camera but I usually take a few shots with the sony then swap the bronica on to the tripod and take one with that. I just expose +1 stop but know to do this from practise.

I did go to my local camera shop to buy a meter and the guys there said to just use my rx100, gives you lot's of metering options and a text shot.
 
this is exactly what i was thinking regarding the OP question. i bought a r67 proii and have a digital 70d. i want to rent a location and do some test shots for a project and thought of using my 70d to test for exposure and lighting. Im gonna be using continuous lighting.

my thinking was using liveview with spot metering to check shadows and highlights would act like a polaroid.

light meters are a tad pricy. location will have mixed lighting so sunny 16 wont be useful.
 
Sometimes when I shoot my Rolleiflex i use the Leica x1 set to spot to meter the area of main interest in the scene. Author times I simply use my sekonic 308...both systems work well for me but I also rely on the latitude of the negative color film.
