Hot FE 600mm f/4 GM OSS Lens Telephoto Lenses

FEATURES:

World’s lightest 1 600mm F 4.0 super – telephoto lens – The remarkable light weight and excellent balance of the FE 600mm F4.0GM OSS lens – weighing it at only 6.71 lbs.- is achieved through an innovative optical design that includes a large XA (extreme aspherical) element, three fluorite elements and one ED glass element as well as the liberal usage of durable magnesium alloy components. The new design of this well balanced lens, reduces the number of elements deployed at the front of the barrel, resulting in quicker, more precise panning, whether shooting handheld or on a monopod.

XD (extreme dynamic) Linear Motors for fast precise autofocus – To make full use of the rapidly evolving performance speed of modern and future camera bodies, the lens’s focus group is driven by two XD (extreme dynamic) Linear Motors that achieve higher thrust and efficiency than conventional types of AF drive motors. The XD Linear Motors deliver new levels of fast, precise, quiet autofocus operation and contribute to reliable and tenacious AF tracking that sports and wildlife photographers will appreciate. Additionally, a new algorithm developed specifically for the XD motors, notably improves their response, minimizing lag and instability that can occur when driving a large aperture focus lens group, resulting in quiet, low-vibration operation.

Superlative G Master quality – All lenses bearing the G Master brand are designed to extremely high standards, ensuring that outstanding contrast at high spatial frequencies is maintained right out to the image edges. The optical design includes a large aperture XA (extreme aspherical) element and three fluorite elements that help to minimize axial chromatic aberration that can be a problem in large-aperture lenses, as well as lateral chromatic aberration that can reduce resolution towards the image periphery. Color bleeding is effectively suppressed, allowing clear reproduction of the finest subject details, while Sony’s original Nano AR coating suppresses any unwanted reflections, glare, or ghosting.

3x fluorite elements, 1x ED glass element reduces flare and ghosting – Based on a new optical design that conforms to stringent G Master standards, the FE 600mm F4.0GM OSS includes three fluorite elements and one ED (Extra-low Dispersion) glass element that help to reduce chromatic aberration, a common problem in telephoto lenses. Extremely high resolution is maintained right out to the image edges. Spherical aberration is optimized to create a perfect balance between high resolution and soft, beautiful bokeh through careful control at both the design and manufacturing stages. Each lens is individually tested and adjusted to achieve ideal characteristics.

Wide F4.0 max aperture – The wide F4.0 max aperture maintains exposure and depth of field while also allowing maximum light for shooting in almost any condition. When changing your aperture to defocus the background, the areas out of the focal plane appear blurred. This ‘bokeh’ effect of the blurred background can be enhanced with circular aperture blades used in this lens.

11-blade circular aperture contributes to gorgeous bokeh – Complementing the wide F4.0 aperture are the 11-blade circular aperture blades that result in soft-edged bokeh that is a hallmark of the Sony G Master series. While conventional aperture blades have flat sides creating unappealing, polygonal shaped defocused points of light. α lenses overcome this problem through a unique design that keeps the aperture almost perfectly circular from its wide-open setting to when it is closed by 2 stops. Smoother, more natural defocusing can be obtained as a result. In addition to careful control of spherical aberration at the design stage, each lens is individually tested and adjusted during manufacture to achieve the highest possible bokeh quality.
