This is probably one of the hardest questions to answer properly. The same goes for the hi-fi system but I am now on the camera.
I started with the M7 TTL and a 28mm f/2.5, a 50mm f/1.4 and a 75mm f/2.0 and lost all of them on transit back from Hawaii. Don't do bargain airfares that require transit in home airport anymore.
The digital age brought Pentax K7 and then K5 with its range of cute prime lenses (31, 43, 77 mm). Smaller than most, but not an everyday camera.
After all, the best camera in the world is the one in your pocket (my phone is not a camera).
Got a Leica 35mm f/25 (cheapest) and fixed it to a Ricoh GXR (cheap). Used them on my daughter's graduation. Good; used.
Fujifilm tries to be a digital Leica. Bought the X100 when the price fell with the launch of X-Pro. Nice pictures. Slightly bulky.
So much for trying to take some very ordinary pictures once in a while. Mostly black and white, spot meter. The Leica M Monochrom looks fantastic but it costs nearly as much as my car.
