I am dedicating this and other posts in this series to the 3:4 image aspect ratio, as photographed on the Olympus Pen EE-S, Pen EF, Pen FT and other half-frame format film cameras that I have or may collect along the way. I only had one thing in mind when I started the assignment with the Olympus Pen EF - use the camera to shoot only in the portrait of vertical frame mode. Yes, no horizontals or landscape mode, only verticals in the 3:4 image aspect ratio. The camera I will be using for this series is the Olympus Pen EF, which incidentally, is the last of the half-framed Pen Series cameras produced by Olympus. Fitted with a superb f/3.5 28mm lens, the EF is an all black model with white lettering. The design is further complemented with a flash unit powered by an AA battery.
A half-frame camera, also known as single-frame or split-frame, captures images at half the size (18x24mm) of a standard 35mm negative film (24x36mm). You can shoot twice as many pictures and get 72 exposures on a 36-exposure roll, 48 on a 24-exposure roll. Most half-frame cameras are manufactured with a vertical film framing setup, meaning that they shoot in a vertical (portrait) orientation as opposed to the horizontal (landscape) orientation of standard 35mm cameras. Operating the camera, as a point-and-shoot, is equally easy and can be done one-handed. Metering is by the standard Selenium 'electric-eye' system with the red pop-up flag that locks the shutter in low light condition. With the Oly, ous EF however, you can override this lock by activating the level to power the flash unit, cute.
