How do you deal with viewfinder eyestrain?

Pretty much all digital SLR viewfinders suck.

Hah. Thanks for confirming my suspicions. I thought it was just me for a while. Any idea why DSLR viewfinders are so bad? Is it a design limitation, or are the manufacturers just being cheap?

This is the main reason I started looking at the electronic viewfinders on the micro 4/3 system. But I think the AF performance on those systems is not quite there yet, at least for Olympus.

How much of a performance hit do you take when using live view for action or wildlife shots? Is there increased shutter lag or decreased AF speed? I read in a review somewhere that switching the AF mode may still result in acceptable AF speeds while using live view.

The thing is, if I'm in live view most of the time, I guess I may as well be using micro 4/3.

Antz is mostly correct AFAIK. There are viewfinder brightness differences between dSLR models regardless of the lens attached. I believe this is due to how the viewfinder itself is made in different models.
