It's the one thing I do love about full frame and 35mm, the sensors are large so you get a very good view of the scene through the viewfinder.
I also have a Canon SX30 but never use the EVF, i'm so used to a much larger view I always use the screen instead. I know that uses more battery but at least I can track subjects better. When shooting HD macro I have to make sure i've got the subject in focus as it moves so the EVF is a complete no no for me.

It's not that often I take the SX30 now, it all depends what i'm doing. As technology has moved on so much the Panasonic TZ series make a much more pocketable solution for an SLR companion. I generally take 4 cameras out at all times so I have everything covered, but again as I said it depends what i'm shooting.
