Pentax Spotmatic
Kodachrome - Hong Kong
The Shutter Speed control
This is another dual control
The outer silver ring can be pulled up and rotated to select the iso setting for the in-built light meter. The user can select from 20 to 1600 iso.
The shutter speed settings are set by rotating the knob without lifting the ring. The camera supports bulb and speed settings from 1 sec to 1/1000th sec with flash sync at 1/60th sec (x setting).
Shutter release
This is just a straight push. For those used to more modern cameras there is no auto focus activation with a half push.
The centre of the release is threaded for a standard shutter release cable. Immediately to the right of the shutter release is a small round indicator. This changes to a red circle when the shutter is cocked and ready to fire.
Film advance lever
This is a single action lever which makes it fast and easy to use. The small window set into the dial shows the current frame number. The counter resets to -2 when the back is opened. When loading a new film the lever is advanced and the shutter fired until the dial reads zero. To make the first image it is then advanced to frame number 1 and the camera is ready to fire.
Pentax Light Meter
In its day the penta-prism and through the lens light meter design were revolutionary. The Spotmatic has a light meter viewable within the view finder and requires a battery to be installed under the cover in the bottom of the camera. I find these days that whilst an L44 button battery can be used it is easier and more accurate for me at least to use my external Sekonic L508 meter. In use the Spotmatic will close the aperture to your chosen value automatically. The meter needle is then centred in the finder by altering the aperture and shutter speed settings. Correct readings from the light meter depend on setting the film speed in the ASA (ISO) dial within the shutter speed control ring on the top of the camera. The best way to use the internal meter is to ensure you have accurate focus first, then push the meter switch up to turn on the meter and stop down the aperture which may darken the viewfinder considerably. Finally vary the shutter speed or aperture to centre the meter needle in the viewfinder. Since the meter sensors average the whole viewfinder I found in practice that it was fairly reliable and accurate at assessing exposure so long was you compensated for extremes in contrasty situations.
