Olympus Trip 35 Aperture Settings
The Olympus Trip 35 has the following aperture settings on the ring, 2.8, 4, 5.6, 8, 11, 16, and 22, and these are also known as f-stop numbers. The aperture is one of the most important parts of a camera and usually used together with the focusing ring. Both of these settings determine how much of your photograph is in focus. By reducing the aperture, you increase the depth of field. Hence, a smaller opening means more of the photograph will be in focus. When the f-stop ring is set to "A", the camera operates through the automatic metering system, where you are likely to see a red flag if the light level is not enough.
On the Olympus Trip 35, the shutter release button also has some control over the aperture setting. When pressing this button half way down, the system takes a light reading and locks the aperture for that reading.
Aperture Setting and Opening Size
A smaller aperture number means a larger opening of the aperture, and the relationship is inversely proportional.
![Aperture Formula](olympus-trip-35-aperture/olympus-trip-35-aperture-formula.gif)
This very simple formula gives an approximate area of the aperture opening based on the aperture number N, which on the Olympus trip is 2.8, 4, 5.6, 8, 11, 16, and 22. This formula is for a camera with a focal length of 40 mm.

This chart shows an approximate opening of the aperture.
Aperture Number | Area (mm²) |
2.8 | 160.28 |
4 | 78.54 |
5.6 | 40.07 |
8 | 19.63 |
11 | 10.39 |
16 | 4.91 |
22 | 2.60 |
In this chart, the first column shows the aperture number, and the second shows the area of opening. Note that in the area column, each successive area is approximately half that of the previous one. Also, note that the area gets smaller as the aperture number gets larger.
