Installed technology A brass mount that combines high accuracy and robustness.In order to withstand long -term use, the surface treatment has been applied to enhance strength, and high -quality lenses are realized.
Mount is adopted rubber sealing to protect the mounting part that is most worrisome about intrusion of garbage.
Water repellent and anti -fouling coating that can easily wipe off water drops and prevent fats and fats from adhering.It will help you use comfortable use in harsh situations and to maintain the lens surface.
Normal specification polygon aperture is also designed so that the blur of the dotted source is also multifunctional when squeezed, but the circular aperture is designed so that circular blur can be obtained near the opening.
Sigma's unique coating technology "NPC (nanoporouscoating)".It is less likely to be affected by strong incident light such as backlight.
Since the refractive index of the glass differs depending on the wavelength of light, the phenomenon in which the imaging points are shifted for each color are called chromatic aberration.It is easy to appear strongly with telephoto lenses, causing image quality.
