Sony E-mount FE 24-105 mm OSS DSLR Lens (SEL24105G SYX, Black )

MTF Chart:- "MTF (Modulation Transfer Function) describes how well a lens can reproduce fine details, measured as the degree of contrast achieved between finely spaced lines. [1] Contrast (%) [2] Distance from optical centre of lens (mm) [3] At 24 mm [4] At 105 mm [5] Spatial frequency [6] 10 line pairs / mm [7] 30 line pairs / mm [8] Max. aperture [9] F8 aperture [10] R: Radial values T: Tangential values"

Lens Configuration:- "Impeccable Sony G Lens design emphasises a graceful balance between high resolution and gorgeous background bokeh that can enhance the artist's vision. [1] Advanced aspherical lens (AA lens) [2] Aspherical lens [3] ED glass"

Professional reliability and operability:- A fluorine coating on the front element prevents contaminants such as oils, grime and water from sticking to the front of the lens and makes them easier to remove if they do become attached to the lens surface. A dust and moisture resistant design2 and customisable focus hold button further contribute to professional operability and reliability.

Constant F4 and fast, precise, quiet AF for stills and movies:- A bright constant F4 maximum aperture throughout the zoom range keeps the brightness even when focal length is changed. Sony's Direct Drive SSM (DDSSM) AF drive system offers fast, precise, quiet focusing. And a precision optical design minimises focus breathing. All of this makes the FE 24-105mm F4 G OSS an excellent choice for both stills and movies.

A one-lens solution for mobile, versatile shooting:- Excellent optical performance and a high zoom ratio are packed into a compact, lightweight design weighing only 663 grams (23.4 oz). The design extends to E-mount bodies for outstanding system mobility and handling ease. This one high-performance lens lets you shoot a wide range of subjects and situations. A minimum focus distance of 0.38 metres (1.25 ft) and built-in optical image stabilisation further enhance all-around versatility.

Excellent corner-to-corner imaging throughout the zoom range:- Advanced optics achieve consistently high corner-to-corner resolution throughout the zoom range. Four aspherical elements effectively reduce aberration, while ED (Extra-low Dispersion) glass elements minimise chromatic aberration. A circular aperture and carefully controlled spherical aberration shape add expressive potential with beautiful, smooth background bokeh and natural highlights that complement outstanding in-focus sharpness and clarity.

A compact, lightweight and comprehensive zoom:- From 24 mm to 105 mm and F4 aperture throughout the zoom, the high-performance G Lens offers consistently high image quality. In addition to outstanding optical performance, it has a compact, lightweight design for portability and mobility befitting the E-mount system. Fast, precise AF and high reliability add to the broad utility of this fine zoom lens.
