Exposure compensation dial is designed to be operative in 1/3 steps. The LX is equipped with a precise exposure compensation mechanism that moves in 1/3 EV steps between 1/4X and 4X, allowing the photographer to make minute adjustments in exposure. The exposure compensation dial locks at 1X to prevent accidental movement. A red warning tab in the viewfinder appears when the dial has been moved away from 1X.

EXPOSURE COMPENSATION RANGE

While the range of the exposure compensation dial is sufficient to allow exposure compensation at all film speeds featured in the camera's film speed range, with extremely fast and extremely slow films, compensation is not available for the plus and minus settings indicated by the black dots below:

USING THE EXPOSURE COMPENSATION DIAL

Although the center-weighting of your LX camera's metering system is designed to provide accurate exposure measurement under the majority of lighting conditions, when using the camera in the automatic mode you may find that a degree of exposure adjustment is desirable. This is particularly true in scenes with extremely contrasty backgrounds or foregrounds, or where special creative effects can enhance the overall quality of the photograph. The exposure compensation dial allows you to make these adjustments quickly and easily.

ALWAYS SET THE EXPOSURE COMPENSATION DIAL BACK TO THE 1X POSITION BEFORE RETURNING TO NORMAL AUTOMATIC OPERATION

The dial, located beneath the film rewind knob, permits you to override the automatic exposure setting by a full +2 EV (i.e., two full f/stops over or underexposure) in 1/3 increments. The dial is in. indexed at 4X (2 f/stops increase), 2X (one f/stop increase), 1/4X (2 f/stops decrease' and 1/2X (one f/ stop decrease) with click stops at each 1/3 increment. Normal Position: For normal automatic exposure control, make sure the dial is set to the "1X" position. The Dial locks firmly in this position to prevent accidental movement. When the dial is off the "1X" index, a red flag will appear in the upper right-hand side of the camera viewfinder as a reminder.

BACKLIT SUBJECTS: When shooting a subject against a bright background such as a window, bright sky, sand or snow, the camera meter will tend to underexpose the subject. To compensate, press the dial lock release and change the dial towards the 2X or 4X position depending on the degree of additional exposure desired.

FRONTLIT SUBJECTS: When your subject is spotlighted against a dark background such as on a stage, the meter will tend to overexpose subject details creating a washed-out appearance. To compensate, press the dial lock release and change the dial towards the 1/2X or 1/4X position depending on what degree of underexpose is necessary or desirable.

The self timer lever is being designed to operate a triple function as Self-timer/Preview/Mirror-up lever. This is another feature attributes to the overall compactness of the camera body design. The Self-timer, aperture preview and mirror-up functions are all controlled by a single, efficiently-designed lever placed accessibly on the LX's front panel. To activate the self-timer, press the center button and rotate the layer counterclockwise (A+B).

The LX self-timer provides a variable 4 to 10 second delay of the shutter release. Press the lever release button and turn the multi-function lever counterclockwise to set the timer delay. After making sure the shutter is cocked, press the shutter release button to activate the timer run.

The timer can be canceled before the start of its run by returning the lever to its original position. Once you press the shutter release button, it can no longer be canceled. Turning the lever clockwise (C) allows the photographer to preview depth of field at specific preset stopped-down apertures. Turning the lever clockwise while pressing the center button (A + C) locks the mirror at the up position for reduced mirror shock during shooting, great and invaluable feature for macro and astronomy photography. It is not necessary to lock up the mirror for motor drive photography. To release the mirror lock, press the lever release button again.

You may have noticed the LX hasn't got the strap lug at both sides of the camera body. It has been moved to the front panel, not just two, but dual-position, three in total - works in combination to suit individual preferences. The LX has 3 strap lugs, two near the top of the front panel and one near the bottom. This allows the photographer the option of carrying the camera horizontally or vertically. With an accessory grip attached, the LX provides an extremely firm grip, with the right hand on the grip and left hand wrapped around the strap placed at the vertical position. We haven't seen that on any earlier camera, neither on any current models (May be I am wrong). It can be used in two ways. Before attachment, press the twin tab of the fastener (
A) with the edge of a coin until the single tab protrudes. (B). To carry in horizontally, first attach one of the strap fastener to either Accessory Lug (C) or (D) and press Tab (B) with a coin until Tab (A) protrudes, thereby locking the fastener to the lug. Repeat this process for another fastener. While you intend to make it vertically carried, unlock the fastener attached to the Accessory Lug (C) by pressing Tab (B) until Tab (A) protrudes. Then, remove the fastener and attach it to Accessory Lug (E). Note: Make sure the fastener is securely locked in place after all these procedures, you can test by jiggles the fastener back and forth while pulling on the strap to test it.
