Very Easy to use...with my older eyes I use the Magnifier.
A plus with the Panasonic's, the EVF will get brighter as you close down the lens.
That means at f/8 or f/11 or whatever, the VF stays bright to focus.
I had the opportunity to use a E410 over the holidays. OMG... it was like looking though a dark tunnel. How VF's have changed over the years.
