How are you finding it without a viewfinder?
To me, the additional viewfinder will make the camera only bigger. The primary reason I bought RX1 is compact and easy travel.
Since I came from P&S, shooting through back LCD is not big problem for me. Matter of fact, I like it alot. I'm now able to shoot from lower, higher and diff angle and still be able to see the screen.
Note: I love the 41 AF points on RX1. Kinda like 61 AF points on my 5D III
. My wife took over 400 pictures last weekend. I'll share some pics soon.
