Half-stop steps are used on some cameras. Usually the full stops are marked, and the intermediate positions click but are not marked. As an example, the aperture that is one-third stop smaller than f /2.8 is f /3.2, two-thirds smaller is f /3.5, and one whole stop smaller is f /4. The next few f-stops in this sequence are:
Many digital cameras have a display setting and possibly a physical dial whereby the photographer can set the camera to either over or under expose the subject by up to three f-stops in 1/3 stop intervals. Each number on the scale (1,2,3) represents one f-stop, decreasing the exposure by one f-stop will halve the amount of light reaching the ...
Increasing f-stop decreases the aperture of a lens. In photography, stopping down refers to increasing the numerical f-stop number (for example, going from f / 2 to f / 4), which decreases the size (diameter) of the aperture of a lens, resulting in reducing the amount of light entering the iris of a lens.

This camera has a fixed shutter speed, so the "EXP VALUE" ring simply sets the aperture. On most cameras, there is no direct way to transfer an EV to camera settings; however, a few cameras, such as some Voigtländer and Braun models or the Kodak Pony II shown in the photo, allowed direct setting of exposure value.
The E series uses a unique additional optical system that enables the small sensor to capture the field of view of a 35mm film, with a crop factor of 1. This comes not at the expense of the F-stop of the lenses, because the light is bundled to the 2 ⁄ 3 inch CCD sensor with approximately 16 times smaller area.
It is known as the EOS Kiss F in Japan and the EOS Rebel XS in the United States and Canada. The 1000D is an entry-level DSLR that has been described as being a step below the 450D. [1] The camera shares a few features with the 450D. [2] [3] It offers Live View shooting, DIGIC III Image Processor, and SDHC media storage. However, it has seven ...
