Translation of "Blendenwert" in English

In case of wrong exposure, sensitivity or aperture settings must be altered.

The f-number may be determined as a spot or integral.

This increase is more obvious when the lens aperture value is less than 2.

What does a nominally identical aperture value mean for cameras using different sensor sizes as to light intensity an depth of field?

I chose a medium aperture and ISO 100 for low noise.

If a fixed voltage is present at the potentiometer resistor, a voltaqe occurs at the potentiometer pickoff which is an analog measuring signal for the diaphragm number and as such is fed to the microprocessor system in digitalized form.

In German Patent DE-C 30 45 157, a lens carriage having three lenses is described, in which the diaphragms of the individual lenses, by means of a common adjusting device, can be adjusted manually to given positions which each correspond to a fixed diaphragm number, and the adjusted positions are detected by means of correspondingly arranged microswitches which are electrically connected with one another and with an indicating device.

If the f-number exceeds or fails to reach the optimum f-number, it will be possible to change the exposure time via an exposure time setting circuit coupled to a brightness calibration potentiometer 15, which forms part of the circuit 11 and which will be described hereinbelow.

The lower the aperture value (the larger the hole), the lower is the depth of focus.

After connecting the camera to the computer with a USB cable, the user can take photos and adjust the aperture value, shutter speed, and other settings.

In addition, the aperture priority function is also helpful for those cameras where, in spite of having no objective lens (TLS APO), an f-number can be input manually via the menu.

1968 onwards (Autoreflex T) additional coupling for the widest aperture of the lens to the camera body (for TTL metering)

The later variations for the AR bayonet additionally have an EE position for fully automatic exposure, where the camera body selects the aperture used.

Certainly the coupled light meter of the Konica F will not work properly with lenses that don't have the coupling lever for the aperture value.

Now I want to address my second question that I asked at the beginning, here in a somewhat generalized form: What does the same aperture value mean for a camera with a smaller sensor and for a full-frame camera?

In the viewfinder, the distance index bar is displayed together with the depth of field scale and aperture value, providing helpful guides for focusing.

In addition to the 1.62 mega-dots 3.0 inch TFT LCD main monitor, the rear of the camera features a sub-monitor that displays the number of remaining shots on the SD card, shutter speed, aperture value, ISO level, and more.

As for situations that make you hesitate to zoom in all the way for fear of diffraction, this technology allows you to use apertures up to F16 for FUJIFILM X100S (fixed single focal length lens) and up to F8 for FUJIFILM X20 (zoom lens), providing ample opportunity to show the function of their lenses.

For further facilitating the control of the camera, in another configuration a f-number (i.e. a transmission aperture of the lens leading to the sensor/brightness sensor of the camera) of the camera is defined/fixedly set (especially when an exposure time value of the camera can be set).

Alternatively, said f-number of the camera is adjustable/variable (especially when an exposure time value of the camera is defined/fixedly set).
