What camera should I buy instead of the leica q2?
The site doesn't have a direct alternative to the Leica Q2 in its catalogue. Its Leica siblings are the closest match. The Leica Q2 Monochrom has the same 47-megapixel full-frame sensor but shoots black and white only. The Leica Q3 43 is newer, with a 60-megapixel sensor and a 43mm f/2 lens in place of the 28mm.
If you want a different kind of camera, I'd start with your first camera. It suggests a mirrorless camera with an APS-C sensor, or a 1-inch sensor compact if you want something that fits in a pocket. Either will cost less than a Q-series, and the lenses matter more than the body.
If you buy used, buying used explains how to avoid the common traps.
