The aspherical lens element in Sony's "G Lens" achieves much higher lens contrast than conventional spherical lenses. Moreover, ultra-high refractive index lenses tend to be smaller in lens thickness and diameter than regular glass lenses, resulting in reduced overall lens unit dimensions.

Contrast, which tends to deteriorate in wide-angle and high-zoom ratio lenses made of regular glass, is also enhanced. Ultra-high refractive index lenses utilize glass with a refractive index significantly higher than that of regular glass, resulting in much more effective correction of spherical aberration. A much higher refractive index than regular glass is what makes the difference. This lens element contributes to exceptional lens contrast at all focal lengths from wide-angle to telephoto. Thanks to an ultra-high refractive index lens element and aspherical lens element, the sophisticated "G Lens" delivers exceptional lens contrast. One of the leading determinants of lens quality is lens contrast, which refers to the ability of a lens to differentiate between small details. Now that Sony employs these lenses, highly effective correction of chromatic aberration has become a reality. Even when shooting with a fully open aperture, Extra-low Dispersion lenses deliver crisp, clear, high-contrast images from corner to corner.

ED glass also features uniquely irregular dispersion that dramatically reduces chromatic aberration. Extra-low Dispersion lenses, developed as a solution to this problem, are composed of ED glass featuring significantly lower dispersion and a lower refractive index than regular optical glass. This results in reduced contrast, increased colour fringe and an overall loss of detail. With regular optical glass lenses, chromatic aberration generally increases as the focal length increases (such as in high-zoom ratio and telephoto lenses). Through reduced and irregular dispersion, as well as reduced refraction, ED lens significantly reduces chromatic aberration in comparison with regular lens. The HX1 corrects chromatic aberration through various advances, including an extra-low dispersion lens element (ED lens) composed of ED glass. This phenomenon, called chromatic aberration, is significantly reduced in photos taken with Sony’s sophisticated "G Lens". You may have noticed an unnatural colour fringe on the edges of objects in photos taken with regular glass lenses. Whether shooting dramatic landscapes or groups of friends in small rooms, the "G Lens" is the right choice for outstanding results.Įffective correction of chromatic aberration The "G Lens" combines a minimum focal length of 28 mm and a large F2.8 aperture to deliver wide-angle images of crisp, razor-sharp quality.
