![]() Yet residual chromatic aberration known as “secondary spectrum” may still remain. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. The result is chromatic aberration, the color fringing that is particularly noticeable in telephoto lenses. This fact causes different colors of light to focus at slightly different points. The degree to which light is refracted by glass depends on the light's wavelength. These features give this F1.4 large-aperture lens truly optimal image quality. And optimized power distribution helps correct various types of optical aberration. ![]() A single FLD glass lens, which boasts the same performance as a fluorite lens, is combined with four SLD glass lenses to minimize chromatic aberration. Putting a large-aperture aspheric lens first in the series of lenses makes possible a slim barrel. As a result, it is possible to achieve a bokeh effect that is cleaner and more aesthetically pleasing than ever before. As compared to conventional 35mm F1.4 lenses, this new lens is designed to produce images with extremely low chromatic aberration. ![]() Thanks to these features, resolution is extremely high from the center to the edges of the photograph.Īxial chromatic aberration becomes a bigger issue with large-aperture lenses. In addition, aspheric lenses help minimize astigmatism and field curvature. This optimization minimizes axial chromatic aberration by causing the different wavelengths of light to strike the same focus position while also minimizing transverse chromatic aberration. In the 35mm F1.4 DG HSM, FLD (“F” Low Dispersion) glass, which is equivalent to fluorite in its characteristics, and SLD (Special Low Dispersion) glass help optimize the power distribution of the lens. There are two types of chromatic aberration: transverse, which can be corrected for with digital processing and axial, which is difficult to minimize after a shot is taken. Chromatic aberration is among the most important, and minimizing it is essential. Several types of optical aberration can affect the image quality of a lens. Hold it in your own hands and appreciate it with your own eyes.Ī masterpiece large-aperture wide-angle F1.4 lens The full realization of the Art concept, the 35mm F1.4 DG HSM is the perfect flagship.
