Simply setting that shutter speed without changing the effective lens aperture would result in an underexposure, but the Ricoh 500 will automatically change the aperture setting to f / 8.

There is an aperture setting switch on the camera with two positions indicated by pictorial ideograms : " sunny " and " cloudy ", with a nominal value of and, respectively.

The last development of M42 lenses was the introduction of a link between camera and lens to transmit the lens aperture setting, which allowed light metering with the aperture remaining wide open.

The CM-1 featured a battery-powered through-the-lens light metering system that utilized a red-above, green-middle, and red-below to indicate whether the shutter speed / aperture setting was over / ok / under exposing the picture.

The manual setting options on the DC-T50 allowed me to try different shutter speeds and aperture settings, but I found I always could have obtained the same or better results in the auto mode.
26.
The FM2 was not designed for budget-minded snapshooters who would never bother to learn to utilize shutter-speeds and aperture settings, but rather was intended to appeal to serious photographers who demanded a tough, rugged camera.
27.
A slot between two of the bayonet tabs on the lens allows the " stop-down coupler " from the camera to sense the aperture setting on the lens and adjust the light meter display accordingly.

The Reflex III of 1961 and Reflex IV of 1964 brought minor improvements with the former offering a metering needle visible in the finder, and the latter allowing shutter and aperture settings to be visible in the finder.
29.
The 35, 52 and 85 mm all had a linkage that juts out from the side of the lens, that inter-connects with a lever on the front of the camera, to register the lens'aperture setting with the camera's metering system.

An additional implication of the 5.6?crop factor and associated optics is that depth of field ( DOF ) is increased proportionally for a given aperture setting ( in comparison to the 35mm equivalent DOF at the same aperture ).
