Remark: It looks like the cameras listed as "Sankyo CM Number" should be called "Sankyo Super CM Number". On the other hand these could be different models, too. Some of the "XL" cameras are able to record sound what their name in the list should include.
It's also unclear whether the "Hi-focus"-models really did have the "Hi-focus" in their name or whether the same camera was available with and without the "Hi-focus"-feature.
