Thanks a lot!
The KX was released in 1975. The body was basically an updated Spotmatic. It featured mirror lockup, a shutter speed indicator in the viewfinder, and a window that showed what aperture was set.
The MX was released in 1976. It was meant to be a high end system camera, but not as high end as an F2. It was the only fully mechanical camera in the M series. Like all the cameras in the M series emphasis was placed on size reduction.
The LX was introduced in 1980. It is a high end professional camera aimed squarely at the F series. It is a full system camera with interchangeable viewfinders, focusing screens, data and film backs, battery packs, and winders / motor drives. It is slightly larger than an MX but much smaller than a Nikon F3. It featured a mechanical shutter speed of 1/2000s, a flash sync of 1/75s and bulb. But slower shutter speeds, 1/60s to 4 seconds are controlled electronically. In automatic exposure mode, exposures range up to 125 seconds.
The LX also had the best light meter ever installed in a SLR. To quote Wikipedia
Quote: The LX has excellent low-light performance using dynamic, off-the-film-plane TTL metering called Integrated Direct Metering (IDM). Pre-release exposure information is obtained from light reflected from a patterned shutter curtain back to the sensor. This exposure metering makes the camera excellent for available light photography. TTL flash control is also available using Pentax dedicated units.
The sensitivity range is -6.5 to 20 EV.
