| Olympus Trip 35 |
The Trip 35 is a fully-automatic compact camera, manufactured by Olympus from 1967[1] to 1984, during which time over ten million units were sold.[1] The auto-exposure mechanism is entirely solar powered by a selenium cell surrounding the lens, and consequently the camera runs entirely without batteries.
Auto-exposure mechanism
With the aperture ring set to "A", the camera operates as a program automatic, choosing both the aperture and shutter speed (of which there are only two, 1/40 and 1/200). As explained by one repair page,
- The camera uses a "trapped needle" mechanism for setting the proper exposure. The aperture is held stopped down to f22 by a spring. When the shutter button is pressed, a bar comes up and “traps” the meter needle against a plate. Following right behind the bar is a cam which is connected to the aperture blades. This comes up until it touches the trapped meter needle. The distance the cam travels determines how far the aperture opens.
The combination of aperture and shutter speed that the exposure mechanism chooses depends on the amount of light available. Above EV 13, the Trip 35 will increase the shutter speed to 1/200 sec in preference to using a smaller aperture, and use a narrower aperture as light levels increase from there, presumably to avoid the diffraction effects that affect all 35mm cameras below f/11.[2] Below EV 13, it will use the 1/40 sec speed and widen the aperture for lower light levels. The camera will refuse to fire if there is not enough light.
When the aperture is set manually (primarily for flash photography), the shutter speed is set to 1/40th of a second. However, the meter is still active even in this "manual" mode. Setting the aperture manually merely sets the widest permissible aperture, and the auto-exposure mechanism may still choose to set a smaller aperture than this if it sees fit.[2]
Other than this, the camera offers no controls for setting exposure manually, though one can easily set exposure compensation by changing the film ASA dial to a higher or lower value.
Lens
The Trip 35 has a 40mm f/2.8 Zuiko non-interchangeable lens, with four elements in three groups. Ken Rockwell suspects this to be a front-element focusing Tessar.[3] This lens has a reputation for being extremely sharp, even in the corners; in Rockwell's tests, Costco-scanned Fuji ISO 400 print film loaded into this camera out-performed a Canon 17-40 f/4 L lens in the corners.[3]
The lens provides simple zone-focusing with 4 cute distance symbols marked on the top-left of the lens. These correspond to the real distance markings on the underside of the lens: 1 meter, 1.5 meters, 3 meters, and infinity.
Viewfinder
The viewfinder is an albada-type, with parallax markings for closer focusing. There is a second, very small window under this, nicknamed the "Judas window", which shows the current aperture setting and distance symbol.
A small red flag will appear in the viewfinder if the auto-exposure mechanism decides there is not enough light and refuses to fire.
