, however, is lighter still (must be remarked that OM-2 had fixed viewfinder, while Canon, Nikon and Pentax ones were interchangeable).

As expected of a professional camera at the time, the LX provides mechanical shutter speeds, ranging from the X-syncspeed of 1/75 second to 1/2000 second and B, permitting manual operation without battery power, while the slow speeds from 1/60 second to 4 seconds, as well as the exposure meter, is battery dependent. Construction is strong and durable, with a solid cast metal frame and metal covering plates. All buttons and dials are weather and dust sealed, a unique feature not found on other professional cameras of the day. Underneath the satin black finish is black chrome, so that even as the surface finish inevitably wore through in hard professional use, the underlying metal would not look brassy. Both the viewfinder
Viewfinder
In photography, a viewfinder is what the photographer looks through to compose, and in many cases to focus, the picture. Most viewfinders are separate, and suffer parallax, while the single-lens reflex camera lets the viewfinder use the main optical system. Viewfinders are used in many cameras of...

In October 1981, Pentax made available 300 limited edition Pentax LX Gold cameras to celebrate having produced 10 million SLR cameras, the first camera manufacturer to reach that milestone according to the accompanying certificate. The camera and its SMC 1:1.2 50mm lens is partly gold plated and partly covered in brown reptile skin, while some details are made of brown plastic, and it came with a brown ever-ready case. Cameras for some markets such as the USA have brown leather instead of reptile skin supposedly due to import laws. The actual number of cameras made is somewhat higher than 300 since a few where retained at Pentax reserved for their own use. The actual number for sale however was 300 cameras according to Pentax in Tokyo. It is a superb example of Japanese camera workmanship.

Three limited editions of the Pentax LX were subsequently distributed on the Japanese market according to the Asahi Optical Historical Club:

The Pentax LX titanium was produced in 1994 to mark the company's 75th anniversary. The titanium plated limited edition of apparently only 1000 LX cameras for the Japanese market came in a presentation box.

The Pentax LX Titanium was launched in 1996 finished in black in a limited number of 300.

The Pentax LX 2000 with a SMC Pentax-A f/1.2 50mm lens in bright metal finish marked the new millennium in the year 2000.
