What ultracompact digital cameras have decent quality optical viewfinders?

Answer 1

Pentax has really great small cameras. Many of the new ones use only the screen on the back, but some have a view finders. I have had several (I am a junky for new stuff) Pentax cameras and they take amazing photos and they are very compact (S series fit inside an Altoids tin). Great cameras.

Answer 2

You might want to rephrase that question and try again.
With optical viewfinders you'll either get rangefinder (these don't work with zoom lenses) or an SLR (hardly ultra-compact.)
The digital ultra-compacts all have electronic viewfinders/ screens. Unfortunately, I'm not up to date on those models, so I can't tell you which are best. I can give you a few sites for in-depth reviews though:

If you had particular cameras in mind, those sites should tell you if the viewfinders are okay.

Answer 3

I can't reccomend any specific models, but if you can find one where the view finder goes through the lens instead of a seperate window (like an SLR), then I bet that would be good. I'm not sure if those are available in cameras other than SLR's though.
