metering with another camera.
My Hasselblad 501 doesn't have an exposure meter so I used my 35mm as one. Than I discovered that the exposure results between the two where different when I also shot some of the same film in the 35mm. So I checked it with another camera with a build in lightmeter and the metering was different.....
Does this mean I can't use my little nikon as a light meter for the Hasselblad?
BTW I used the SAME RELATIVE FOCAL lenght lenses on all camera's 80 on the hasselblad, 50 on the 35mm camera and 33,3 on the digital one. The apendeture was f/5.6 on all cameras. The cameras with lightmeters gave completely different shutterspeed advice. (it's a nkon FE and a digital D70 both set at matrix metering.)
I am back to film but it would be great to use the D70 as light meter for the 501, the D70 has a fairly nice spotmeter build in so I don't need to buy a lightmeter yet.
What about a hand meter?
Check Minolta, Sekonic or Gossen products, EV values capability will be excellent.
Just a suggestion!
I know a light meter would be better, at the moment I don't have any money for that though so the meter in one of my other cameras would be a great solution for a while.
A light meter works for all cameras so there should be a way to use one camera with a lightmeter and do something with that reading for another one. In case this was impossible there should be different meters for each camera right? I mean the lightmeter would work for the Hasselblad and for the Nikon, so the Nikon should work for the Hasselblad, there is a relation.
But there is no doubt your suggestion is the ideal but for now impossble solution.
There is no technical reason why using a camera as a light meter will not work fine. A few people report success with this.
You will get differences of exposure between different cameras because they use different "intelligent" metering methods and will therefore react differently to the same scene (although you would expect them to be within half a stop or so of each other when metering a "normal" scene). If one of your cameras has a "spot" metering mode, use that with a long lens (to make the spot as small as possible) and use it as a spotmeter. That will get around any confusion caused by the camera's "intelligent" metering modes...
You do not need to use equivalent focal lengths: 1/60th @ f/8 is 1/60th @ f/8 with any lens (of course, you need to set the same film speed too). The only real downside is the bulk and weight..
I used to do the two camera switch too. My Nikon f401 metered for my Yashica TLR. Works fine, just a little testing to find what works best for you. For me I prefered just a bit more exposure on the TLR then what the Nikon reported. I guess this is exactly what BobF is saying about metering meathods of cameras. (there were other complications for me like the shutter speeds on the TLR were different than standard camera settings: 1/5 sec, 1/10 sec, 1/25 sec.)
To find the best results I metered with Nikon, then bracketed on the Yashica. 1 stop over, 1 stop under, you know...
In the end I bought a handheld light meter. I find it is more convient to use, and won't go back to two camera metering unless forced. Carrying one less camera (and accessories for said camera) means more room for film and is supposed to mean less weight, but never seems to work out that way.

It's proved again: If you have one lightmeter you always know what the exposure is. If you have two, you can never be sure...
So either use just one, or get another one and go with 2 out of 3!

and, just to cloud the issue. It could be that the variable is actually inaccurate(differing) shutter speeds. Tolerance is about 25% so if one is slow & one is fast, that's a total of 1/2 stop.
What you could do, if only for your own sanity is do a film test using one camera for the meter & the 'blad for exposure.

The Yashica does not have a built in light meter.
What I meant to say was I no longer use the Nikon as a meter for the Yashica.
I think its fine... I always shoot a three shot bracket though, just in case.... At the very minimum, I shoot two... One metered and one overexposed a stop..
You may have to sacrifice a couple rolls of film to testing. Pick a typical scene, set the Nikon to 1/4 sec. Shoot film of identical scene in both cameras but bracket the Hassy by 1/3rd stops. Develop in the same tank and contact print. If you find the 2/3 bracket is the one that matches the Nikon, you can adjust your "asa" accordingly and you should get identical exposures afterwards. I used to use a twin camera platform with my Mamiya Universal back in my Velvia days with great success letting my FE do all the metering work.
