A masterpiece large-aperture wide-angle F1.4 lens
A large-aperture lens with minimal axial chromatic aberration and superb peripheral resolution.
Several types of optical aberration can affect the image quality of a lens. Chromatic aberration is among the most important, and minimizing it is essential. 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. 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. 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 addition, aspheric lenses help minimize astigmatism and field curvature. Thanks to these features, resolution is extremely high from the center to the edges of the photograph.
High resolution with beautiful bokeh effects
Minimal distortion combined with beautiful bokeh effects at large-aperture settings.
The aspheric lens at the front of the lens series helps minimize both distortion and vignetting. The rounded diaphragm produces an attractive round bokeh effect at large-aperture settings. Optimized power distribution minimizes sagittal coma flare. Coma of point light sources near the edge of the image and axial chromatic aberration are both minimized, making the lens an excellent choice for photographing nighttime landscapes and heavenly bodies.
