That brings me back to my studies(1979-81); then owner of a Zenit E and a Spotmatic, I dreamed of a sophisticated camera, compatible with my M42 screw lenses; this "pro" camera released in 1980 would have been ideal. Too expensive, I had to content myself with a Praktica B200!
1980, a good year for the "pros": Nikon has released the F3, and Pentax the LX (Canon will release the New F1 in late 1981). A pro camera at the time, what is it? first of all a robust shutter and body, capable of ensuring thousands of photos; then the possibility of adding a strong motor (5i/s against 3i/s for current motors). And interchangeable focusing screens and viewfinders for specific applications (eg scientific photography).
The shutter is amazing: a priori it looks like a simple horizontal scrolling textile shutter, but the curtains are made of titanium!
Other than that? Automatic aperture priority or manual, 4s to 1 / 2000s, complete display in the viewfinder, depth of field tester, mirror lock, and even TTL to Flash.
The prism is the FA-1, with dioptric correction up to -1.5. Too bad, I need -2.25 ! it would have been possible with the FA-1W.
You can see two small contacts at the bottom, for the use of a data back. Of course the catalog of the time offered lots of accessories: lenses, viewers, 250 views back, watch or data back, 3i/s winder and 5i/s motor, both with motorized rewind!
Christophe's LX looks brand new, just a few small marks above the fastenings of the strap (which can be clipped in horizontal or vertical position). Soft case, user's manual, and original invoice (1983, unfortunately the price faded). Camera body, prism, 1.7/50 lens and bag are the subject of separate lines. Also a dedicated flash AF280T (and its instructions), but batteries have leaked and destroyed the contacts.
