Paul,
Zeiss first had problems with the introduction of the gray SF, this was replaced by the improved black model.
7x binoculars are unfortunately a discontinued model, as beautiful as they are, they are very rarely sold and Zeiss will probably not bring any more onto the market.
As a 50s there is the HT 54, which you forgot, a separate series that Zeiss replaced for the FL.
After all, Zeiss has now brought the 32 series models after years, and there is still nothing to be seen at Leica.
I'm more concerned that Leica will fare like Nikon, that EDG are excellent binoculars, but Nikon did not deliver, in the meantime Nikon has departed from the high-end market.
Leica just seems unwilling to keep up with Zeiss and Swarovski, with the Geovids Leica is still ahead, with the conventional binoculars they unfortunately missed the connection.
So there is no Leicabashing on my part, more the worry that a traditional manufacturer of excellent binoculars will disappear from the high-level market, so I would like to see more activities from Leica.
