Hi to all.
I've read with interrest the article "Why I Hate Electronic Viewfinders" and wanted to answer because I'm more optimistic
OK, the Canon G15 viewfinder (among others) suffer from that problem, it's really evident !
But to my big surprise, the viewfinder of my RX100 can be really better if you tweak it.
As I shoot RAW+JPG, I've seen that if you change the setting of the JPG (less contrast) and set the DRO on "Auto", oh fine, you can see deep in the shadows !!
Unfortunately you cannot do this with Canon compact cameras, shame on Canon !
Please Mr. Canon, Sony has implemented that and it works, do the same with your cameras.
Have a Nice day.
