Q:Camera lens how dust?
In order to maintain the X series of high performance and the birth of the shutter assembly of the closed structure, to prevent dust into the fuselage internal measures have also been fully considered. As the basic idea of the XF system, first, the use of "around the sensor to implement a closed structure" to prevent dust from touching the sensor. In the bayonet surface and the sensor inserted between the three pieces of glass, heavy structure to prevent dust from entering. Second, the dust once into the fuselage when the internal countermeasure. The three cups of glass inserted between the bayonet surface and the sensor are mounted with piezoelectric elements as a "dust removal system". Using about 80,000 times / second vibration to remove the glass surface attached to the dust. In order to pursue the miniaturization of X-Pro1, both the bayonet and the dust removal system are kept thin and lightweight, and the basic performance is not affected at all. This rigorous design ensures high accuracy and reliability. Although the simple, but very sincere - which condensed everything for the sake of the user's design ideas.

Q:What does the camera's lens mean? How to understand
The focal length is the measure of the aggregation or divergence of the light in the optical system, which refers to the distance from the center of the lens to the focus of the light gathering. It is also the distance from the center of the lens to the imaging plane of the film or CCD. An optical system with a short focal length has better ability to collect light than a long focal length optical system. Simply say that the focal length is the distance between the focus and the vertex of the mirror.
