What is the fn key in d6 10 Nikon and what is its function?

This is one of Nikon's unique function keys, mainly to let users set a designated function for Fn in the menu, which is convenient for quick adjustment when shooting. There are also two keys on the right side of the lens bayonet, namely: the lens bayonet lock and the focus drive mode switching key.

Lens bayonet lock:

As the name implies, it is used when unloading the lens. When you unload the lens, you need to hold down this key and then rotate the lens to unload the lens.

Focus drive mode switch key:

Used to switch three focusing modes, namely: c "continuous focusing" is used to shoot moving objects, and the system will focus continuously and can press the shutter at any time; S's "single focus" is used to shoot still objects, and the shutter system focuses once every half time. Different from continuous focusing, if the camera is out of focus, you can't press the shutter to shoot;

M "Manual focusing" is used for shooting scenes that need high focusing accuracy, such as macro photography, and it is necessary to manually rotate the lens focusing ring for focusing shooting.

Other key functions

1，WB

WB bond is the abbreviation of white balance. Because most people switch the white balance to automatic and let the camera judge the appropriate color temperature according to the scene environment, the frequency of use is low. But if you want to regain control of the color temperature, you still need to know the color temperature setting in WB key.

2.ISO key

Due to the frequent use of the sensitivity button, when the picture is dark, most people will increase the sensitivity of the photosensitive element to light by increasing the sensitivity, thus increasing the brightness. Because of frequent use, most SLR cameras will set the ISO key as an independent key.

3, BKT key

This is the bracketed exposure button. When novices are not familiar with exposure value, they can shoot with bracketing exposure. When starting this function, you can increase or decrease the exposure based on the current exposure value, and take 3-5 photos. In addition to exposure value, many cameras now offer white balance surround exposure.
