So the FM3A and Pentax LX pass the test, eh? Aperture priority auto exposure and use of ALL shutter speeds if the battery dies.
No, as previously stated the LX is only available for speeds faster than it's sync speed. This is the same with most if not all of these. The FM3A has the only hybrid shutter that allows for AE and a full range of speeds. It also has AEL. A camera with AE but no AEL is not the best to use.
