|1936 Art Deco Karat - 1938 karat|
The lens is a three element Igestar lens (Sometimes with a fancy "I" which makes the name look like Jgestar). The view finder is a reverse Gallilean finder which gives a small image (the 'reverse' part of reverse Gallilean means it is like looking through a telescope the wrong way with a smallified image). On the original Art Deco version, this viewfinder is not only rather small but is low down on the body, making it hard to use.
