Eos 5d Custom Functions
The technology of ISO settings on digital cameras replica of the nominal speed films of yesteryear. In very general terms, the ISO is the sensitivity of light sensor in the same way that the speed of the film were more or less sensitive to light. But there are differences between film and digital sensors, in particular, the adjustment increases the sensitivity in a digital camera, the sensor output is also amplified. This is called film grain when using high speed. Thus, although has the potential to increase the ISO at any moment of firing, compensation for increasing the amplification or accumulation of an excessive burden on the pixels is increased digital noise. And the result of digital noise is a total loss of resolution and picture quality.
In part because of the 5D Mark It has relatively large pixels because the sensor and Canon has done a good job of applying advanced noise reduction internal processing, the 5D Mark II is distinguished as the best performance including high sensitivity settings, particularly in the exposure time of 30 seconds or less.
In this intelligently taken from point-and-Shoot, ISO sensitivity auto control sensor depending on the mode of shooting where you are in any or Creative Auto, P, Tv or Av, the camera selects a range between ISO 100-3200. Change M, B, or add a Speedlite and dams Auto ISO 400. Auto ISO is indicated by one on the LCD screen when you select and is in the bottom of the ladder by turning the main left after pressing the button selection of the ISO.
ISO range and function of custom options
The 5D Mark II offers a wide range of sensitivities ISO, including automotive and configuration 100-6400 or 1/3-stop increments 1/2-stop increments, set using options C. Fn I-01. ISO range can be extended to include ISO 50 (shown as L), 12800 (shown as H1), and an incredible 25,600 (shown as H2) by the creation of C. Fn I-03 The. Note that the ISO 50 reduces the dynamic range of highlights by about one stop, which makes this less useful sensitivity to light contrast high. ISO 50 can be useful in a studio, a flexibility in the choice of the opening.
With the 5D Mark II, Canon offers an option to reduce or eliminate noise in long exposures.
With the noise reduction at long exposure option, using available C. Fn II-01, the noise is almost eliminated all or processing device that is very capable, but it has almost as much time to complete exposure.
Setting the ISO and ISO Extended Range
To change the ISO setting on the 5D Mark II, follow these steps:
1. Press the Select button above the ISO-LCD panel. The ISO setting being displayed on the LCD and viewfinder.
2. Turn the knob quick order to be more sensitive or left to create a lower sensitivity. ISO settings for the device that you turn the dial. If you have activated the ISO using the expansion C. Fn II-01 and ISO 50 is presented as L, ISO 12800 is indicated as H1 and H2 is represented by 25,600. The ISO option you select remains in effect until you change them again.
To enable the expansion of ISO proceed as follows:
1. Press the Menu button, then the slope of the multi-controller custom function (orange) menu.
2. Press the Set button. The Custom Function screen appears, and the control of the custom function number in the upper right of the screen activated.
3. Turn the control knob for rapid C. Fn I number to 03 and then press the Set button. The expansion of ISO Control is enabled.
4. Turn the dial knob to the right to select option 1: On and press the Set button. ISO expansion continues to be active until you change it.
