Thanks everyone for the comments.I had been aware of Ensign Selfix folders for some time,but in their 6x9 and 6x4.5 versions,similarly I had read that Ross Xpress lenses had a very high reputation.However for some reason I was unaware that Ensign also produced the 12/20,which resembles in appearance the Isolette and Nettar 6x6 folders ,but has a pop-up viewfinder rather than the built-in type.I've seen a couple advertised recently and been surprised.
I have often hankered after this type of camera,and a British version would be nice to own at some stage,but being unaware of the model,I wondered if for some reason it was not as successful or as reliable as it's larger cousins.Also the Epsilon shutter is not too common,but as Ensign used it on other
models,presumably it has some merit.
If any one has any more insight,would be glad to hear.
Cheers,🙂
Brian.
