I was thinking about it, would anyone else like to have a built in flash meter that works with something other then the E-TTL flashes?
I mean, if I am out in the field doing a strobist kind of work. I usually use my friend's 758DR. But, what if I hit the AE/FE lock button on the grip and it would fire my strobes and use the meter to tell me what the exposure should be. I mean, using the partial/ spot meter in camera would be rather useful and faster. It also would be nice it if worked with the hotshoe/ PC connector since I use both
I think there should 2 options for this, and 3 for "professional" bodies.
1. Will use the meter needle to show you more or less aperture.
2. Automatically change aperture to what would make the correct exposure for the set ISO/ Shutter Speed.
3. ("pro") Use Auto adjust ISO to make current Aperture/shutter speed have a proper exposure.
