Features:
1. Fully open F2.8 large aperture lens

The small ultra-wide-angle lens with a focal length of 11-18mm (about 17-27.5mm equivalent to 35mm film specifications) can shoot powerful and vivid performances. All focal lengths can achieve full-open F2.8 bright aperture, which can be used when shooting stars. In addition, a focusing distance as close as 30cm has been achieved, allowing for close-up shooting with a blurred background and emphasizing the three-dimensional effect.

2. Adopting "HD Coating" to improve drawing performance

The high-performance multi-layer coating "HD Coating" that can reduce the average reflectance in the visible light region to less than 50% of conventional coatings is used to effectively suppress ghost images and glare that are generated under severe shooting conditions such as backlighting.

Note 1: "HD" is the abbreviation of High Definition.

3. Structure suitable for landscape shooting and starry sky shooting

After the focus CLAMP is turned on, the focus position will not move even if the focus ring is turned, which improves the usability of shooting landscapes and starry sky that require long exposure after precise focusing. In addition, considering that the heating wire wound to prevent condensation does not affect the operation of the focus ring to leave space, and the design that the entire lens is made of metal in order to effectively conduct heat, each structural detail is to enhance the lens The operability and ease of use.

4. Dust-proof and drip-proof structure

The inside of the lens adopts a dust-proof and drip-proof structure AW (All Weather) that prevents rain and dust from entering. When combined with our company's digital SLR camera with a dust-proof and drip-proof structure, it can improve the durability and reliability in rainy, fog, and splashing environments.
