The first camera I bought after my return to analogue photography was a Canonet, and it has become my definition of a "perfect" camera. Priority mode and manual mode, easy focusing, and exposure lock. I still haven't figured out if I prefer a 40mm lens or a 50mm lens, so let's say this is *one* of my favorite focal lengths. My only problem with it is that it doesn't meter up to 1600 (yeah, yeah, I know, 800 plus exposure lock [or manual mode] will get me there, but that hasn't really worked for me well in practice.)
The only other camera in the running would be my Pentax ME Super. Meters to 1600, focusing isn't quite as easy as the Canonet's rangefinder, and I don't necessarily have to choose between 40mm and 50mm (though I usually use a 50mm). However, my vanity dictates that I'd rather be seen with a Canonet than an SLR, so advantage Canonet
