2. What is i-Function?
Samsung’s i-Function technology is the first of its unparalleled innovation, which helps the
user take the perfect picture while having full control of the pictures at their fingertips by
controlling the camera from the lens using the i–Function button.
i-Function 2.0
The i-Function 2.0 was first adapted to four lenses, three of them have already been
released and one will be released soon. The upgraded i-Function 2.0 features two
additional features. Users can control six different Smart Filters using ‘i-effect’ to get
creative with various effects. The ‘i-Zoom’ function from the lens whilst in Lens Priority
Mode, lets you easily enjoy a zooming effect during capture even while using single focal
lenses.
The i-Function’s lens priority mode has been further upgraded in the NX200 for hassle-free
setting selection. In selecting this mode, the camera will suggest the optimal setting for
capturing, making it even simpler to take the best possible shots.
i-Function 2.0 Lenses
The Samsung i-Function’s Wide Pancake 16mm F2.4, Macro 60mm OIS F2.8, Movie Pro 18-
200mm F3.5-6.3 OIS, which were released last August and the Portrait 85mm F1.4 lens,
which is scheduled to be released soon are fully compatible with the NX200.

3. How to use i-Function
When the camera is in P/A/S/M mode, many important capturing functions such as the
Shutter Speed, Aperture, EV, ISO, and WB can be selected and adjusted quickly and easily
by simply pressing the i-Function button and turning the focus ring on the camera. Certain
adjustments can be done in certain modes, so please refer to the following chart for specific
details.
Unlike the DSLR which you have to set the function for each shot, i-Function allows users
to control parameters from the lens without having to take their eyes off the subject.

Function lens!
