Hmm. I'd have to see some evidence of problems, but I imagine that if you're really diffusing the light a lot this could conceivably happen.
I don't see how the wedding photography could work with a preview ... given that most of your shooting happens in very constrained, set distances and poses, all you need to know is the right lens opening for the given scenes. I used to do weddings way back in the mists of time with a Nikon F and a Rolleiflex TLR, didn't even have an auto- flash at that time, just a good-old-potato masher, and found that in a reception situation I just had to know three-four setups and click the aperture to the correct one for the situation. With a digital preview, I'd calibrate my head to the setups more accurately and then just dial in the aperture as needed.
