Sony RX1 fulfills its claim of being compact, light-weight and producing full-frame quality images.
The Sony thumb-grip is super functional. I feel a lot more confident holding the camera to experiment with more creative compositions.
I do not find the electronic viewfinder of much use so far.
The Sony leather jacket is great in protecting my RX1 in transport. It also serves as a cool half-jacket and an anchor point for the Black Widow holster pin. And yes, I can leave the lens hood and thumb-grip on the camera and still able to put the camera in the leather jacket cover.
The Spider Black Widow holster together with the Gordy's Sling Strap allow me to carry my RX1 with confidence and shoot without fear of dropping my camera.
