Because the LCD kills my nightvision,

Put some red plastic film over the LCD. The red sensitive receptors in our eyes can be dazzled - without loosing dark adaptation, as they are not used in low light!

[Snip...] and I'm not ready to replace my eyeballs with a tiny LCD screen.

Agreed...

[snip...] I just did some testing. I closed my eyes and let them adapt for a few minutes (after making the room extremely dark, but leaving enough light for my test.  could easily discern the white leg of the clothes drier I was looking at with my bare eyes. I could barely see it through the OVF, and not at all through the eVF (LV)...

I have a GH1 and several Canon Rebels. When my eyes are fully dark adapted (takes a minimum of 30 mins) I can easily see the brighter stars through the Canons.  - I can even see the brighter stars through my Compact OVF (Canon a620). - But not through the GH1 EVF, nothing but a black screen.

The only way I can see anything on the LCD/EVF is to use 5 or 10x magnification. It seems that at 1x, pixels are thrown away. (Perhaps 1 in 4 in both directions? - So maybe only a 1 in 16 chance of seeing a bright star!)

[snip...] As soon as I checked the LCD preview, I went practically blind because I lost my night vision. I could see everything on the screen but hardly anything around me where it was a million times darker.

The other method I often use, is to keep my right (telescope) eye shut when I look at the LCD.

Now how could an EVF help me, even if it didn't kill my nightvision?

One thing I find the EVF/LCD invaluable for, is to focus the image using liveview with 10x mag. Even with 5-10x focus magnifiers, I often found OVF's are a tiny fraction out of perfect alignment. I guess with AF, they were never designed to be used that way these days.

So really I need both!

Regards

Andy.
