Use A Pentax 67 Meter For Exposure

The Pentax 67 uses 120-roll film, producing larger negatives than traditional 35-mm cameras.


The Pentax 67 single lens reflex (SLR) camera was released by Pentax in 1969. The design of the camera is similar to a traditional 35-mm SLR, but is considerably larger. The camera has features comparable to both 35-mm cameras and medium format cameras in the way you hold, focus the lens, and take the pictures. One of the optional viewfinders for the camera is a "Metered Pentaprism Finder" that when installed gives the photographer full TTL (through the lens) metering.


Instructions


1. Press the two-push button side locks -- one located on each side of the pentaprism -- and slide the non-metered pentaprisim off of the camera.


2. Install the "Metered Pentaprisim Finder" onto the camera until it locks into place. As you slide the finder onto the camera, be sure to install the "Shutter Dial Adapter" onto the top of the camera's shutter speed dial. The adapter essentially connects the shutter speed selector on the camera to the same selector on the viewfinder.


3. Lift the outer ring on the shutter speed selector and rotate the ring to the proper ASA (film speed) setting to match the film you have loaded in the camera. Set the shutter speed to match the film speed. If you have 100-ASA film in the camera, set the shutter speed to its closest setting, for the Pentax 67, which would be 1/125th of a second.


4. Hold the camera to your eye and look through the viewfinder. You will see a small window at the bottom of the viewfinder with two needles in it. The window has "+" sign at the top and a "-" sign at the bottom. This known as a "Match Point" metering system.


5. Adjust the lens aperture by rotating the ring on the lens until the needles are overlapping each other. At this point, the exposure is set and you are ready to take your picture.
