Connecting with the NFC Function
The settings for communicating with a smartphone are now complete.
NFC Function Cautions
When touching the smartphone to the camera, be careful not to drop the
camera or smartphone.
Do not touch the smartphone to the camera with too much force. Doing
so can scratch the camera or smartphone.
Just holding the smartphone close to the mark may not establish a
connection. Be sure to touch the mark with the smartphone so that they
come into contact with each other.
Recognition may be difficult depending on the smartphone. Touch slowly
while changing the position or angle.
Another application on the smartphone may start depending on how you
touch. Check the position of the p mark, then touch again.
A connection cannot be established via the NFC function while shooting
with the camera, when the power switch is set to <k>, when there is no
card, or when the LCD monitor is closed with the screen facing inward.
When touching the smartphone to the camera, do not leave anything
between the camera and smartphone. In addition, when a case is
attached to the camera or smartphone, communication may not be
possible via NFC function.
When Battery Grip BG-E18 (sold separately) is attached, a connection
cannot be established via the NFC function.
The camera cannot be connected to two or more smartphones at the
same time.
By default, the connection settings via the NFC function are saved as the
fourth setting (a setting dedicated to NFC connection) under the name
[SET4(NFC)]. When you connect the camera to another smartphone via
NFC, [SET4(NFC)] will be overwritten.
A connection can be established even when the camera's power is in the
auto power off state. However, if a connection cannot be established,
cancel auto power off, then establish a connection.
