1. The high resolution power of 3 million pixels in the center of the lens fully matches the high-definition shooting of 1.4 million, 2 million, 3 million, 5 million pixels and higher pixel network cameras
2. DC automatic aperture, 3.4x , metal interface, long cable
3. The lens uses a number of special optical glass, while the metal frame (built-in) design, so that the lens appears more stable; With its process, the joints of each part are fine, so that the structure is also stronger.
4. The lens barrel is made of black engineering plastic material, from front end to back end, it is successively: sunshade that can reduce stray light interference and dust, freely controlled zoom ring, zoom ring fixing branch 5. Frame and screw, automatic/manual aperture, focusing ring and fixed screw, anti-wear stainless steel C interface, in order to facilitate accurate adjustment, in addition to the damping design, the zoom ring and focusing ring are also designed with a ring gear

(Based on the swiper production of the atlas scroll, the default 20 columns and 2 rows, just started to use if the number of display is inconsistent with the number of background, you need to manually set the ranks in the loop body settings, in addition to set the ranks in the display need to find the swiper parameters in the code mode, automatic playback time can be modified in the JS file, see the comments in detail.).
