Essentially, SMC is a thin layer of coating applied to the lens elements to minimize the negative effects of light reflection. This innovative technology has been a hallmark of Pentax lenses since the 1970s and has undergone significant improvements over the years.
How SMC Works
The SMC coating works by reducing the reflection of light at the surface of the lens elements. This is achieved through a complex process of applying multiple layers of coating materials, carefully designed to minimize reflection and maximize transmission of light. The result is a significant reduction in glare, flare, and ghosting, which can otherwise compromise image quality.
To put it simply, when light enters a lens, some of it is reflected off the surface, while the rest is transmitted through the lens. The reflected light can cause unwanted effects such as glare, flare, and ghosting, which can resultado in a loss of contrast, color accuracy, and overall image quality. By applying the SMC coating, Pentax lenses reduce the amount of light that is reflected, allowing more light to be transmitted through the lens and resulting in a sharper, more vibrant image.
