I had a little separation anxiety leaving the Leica and the RX1r behind on this trip, but I did it and had no regrets. As you may gather from my recent posts this little GR keeps on delivering.  It won’t fully replace the other cameras, but it always seems to punch way above its weight. Even though it’s a fixed lens (28mm), there is a little flexibility with the addition of the GW3 wide angle adaptor. With the 0.75x conversion it brings the lens down to an ultra wide angle 21mm. Framing and composition will take a little more consideration since you’ll be bringing in so much more into the frame. For the street work that I enjoy it is nearly ideal, especially in tight places like Tokyo.
