respective operation noise will also be recorded. Use an external
microphone (commercially available) (p.163).
In low temperatures, the display speed of the AF points may become
slower due to the AF point display device’s (liquid crystal)
characteristics. The display speed will return to normal at room
temperature.

In low or high temperatures, the LCD monitor display may seem slow
or might look black. It will return to normal at room temperature.
