The good or bad news is that I have plateaued. I am not going through cameras at a fast rate anymore. Plus, following the acquisition of my Google Pixel 2 for Christmas 2017 I no longer feel the need to have two cameras — a big one and a compact. The Google Pixel is my 2nd camera. So, just need one full-frame camera at any one time.
I kept my Sony a7 II for 690-days and took 30,455 pictures with it. I also kept the mega-zoom Nikon P900 around for long time but did not use it much after the first 9 months or so. The zoom was nice but I had become fond of BIG sensors.
Getting to know my new, 3-week old, Canon EOS RP. Need a couple more lenses. Plan is to keep it for at least a year, if not more. It seems pretty capable. Goal is to hang onto the lenses. That is why I went (bcak) to Canon.
