The meter still works on my Leicaflex original. It gets a bum rap for not having a TTL meter, but the last roll of film that went through mine had very consistent exposures. If you go for a leicaflex, you need to be aware that the batteries are not readily available. You can get voltage adapters that fit a S76 battery in place, and there are a few other options also. The non-TTL leicaflex has a mostly non-focusing screen! Kind of like a rangefinder Leica, most of the field in focus with a small spot in the center that shows focus. The SL or SL2 has a focusing screen (nice one) and need the 2-cam lenses for meter coupling. The R series bodies need 3-cam lenses or later for open aperture metering.
