The 135mm F1.8 has 13 elements in total, which include XA (extreme aspherical), Super ED and ED. The XA and Super ED elements in the front group ‘effectively suppress all common telephoto lens aberrations,’ according to Sony. The Super ED and ED glass used in the front element groups replace traditional large and heavy negative elements commonly used to suppress longitudinal spherical aberration. Sony claims this combination of a Super ED and ED element ‘compensate for axial CA, minimize color fringing and maximize overall resolution,’ while the large XA element mitigates spherical aberration.

Producing large XA elements electricity per kwh that don’t negatively affect bokeh is difficult, but Sony claims its 10 nanometer mold precision and other improvements ensure that onion ring bokeh is non-existent. Furthermore, each XA element is individually inspected to ensure smooth bokeh. An 11-blade aperture ensures circular out-of-focus highlights even at F4 and beyond. Sony gas efficient suv 2008’s Nano AR coating is used to reduce flare and ghosting, while a fluorine element repels fingerprints and water.

There are four XD (‘extreme dynamic’) linear motors in the lens – two for each of the focus groups – that promise responsive, accurate and quiet focusing. Sony states this is its first lens to offer two direct-drive SSM linear induction motors to move two separate focus groups – one in the front and one in the rear – for fast focus. These new linear induction motors replace previous piezoelectric-based designs and are capable of moving larger, heavier elements.

The 135mm F1.8 is weather-sealed and features an aperture ring, focus ring with linear response (important for videographers), two customizable focus hold buttons and a focus range limiter with three settings. The latter allows you to fine tune the electricity in salt water experiment lens for your shooting situation and is particularly important given the lens’ close focus distance. If you are shooting distant subjects, limiting focus allows for nearly instantaneous focus without the risk of hunting to extremely nearby distances.

Equipped with Sony’s most advanced optical technologies, the new lens is built to meet the extremely high standards of Sony’s G Master series. The new FE 135mm F1.8 GM offers exceptionally high c gastritis resolution and exquisite bokeh, two qualities that are signature attributes of Sony’s flagship G Master brand. The new lens combines rapid autofocus (AF) acquisition with a lightweight, portable design and a variety of professional functions, making it a versatile, high-performance tool for professional portrait photographers, wedding photographers, sports photographers and a wide variety of imaging enthusiasts.

“Sony’s commitment to growing our lens lineup remains stronger than ever,” said Neal Manowitz, vice president of imaging solutions at Sony Electronics. “Our 31 st native full-frame FE lens and 49 th overall E-mount lens, the highly anticipated 135mm prime brings the acclaimed G Master quality to another popular focal length for both professionals and enthusiasts to enjoy. We will continue to drive market-leading innovation in all aspects of our imaging business, giving our customers the opportunity to capture and create like they never have before.”

Realizing consistently high resolution across the entire frame, even at F1.8, the FE 135mm F1.8 GM boasts an innovative optical design that places XA (extreme aspherical) and Super ED (Extra-low Dispersion) glass elements gas x side effects in the front group to effectively suppress all common telephoto lens aberrations. Additionally, the Super ED element plus one ED glass element are strategically positioned to compensate for axial chromatic aberration, minimize color fringing and maximize overall resolution, ensuring outstanding image quality. For impressive clarity, Sony’s unique Nano AR Coating is applied to reduce flare and ghosting that can occur when shooting backlit portraits.

The new telephoto prime lens utilizes its XA element, refined with Sony’s latest bokeh simulation technologies during the design and manufacturing stages, to control spherical aberration and achieve exquisite bokeh. In addition, an 11-bladed circular gas 66 aperture mechanism contributes towards achieving extremely natural and beautiful background defocus. The exciting new model also features dual-autofocus groups in a floating focus arrangement for improved close-up capability, allowing a minimum focus distance of just 0.7 meters and a maximum magnification of 0.25x.

To ensure that this lens can keep up with fast-moving portrait or sports subjects, the FE 135mm F1.8 GM has been equipped electricity physics pdf with a total of four of Sony’s proprietary XD linear motors—two for each group—that achieve rapid, reliable and speedy AF tracking and performance. There is also a control algorithm that helps to maximize control response and ensure quiet, low-vibration AF. All of this exceptional performance is packaged in a compact, lightweight body weighing in at 33.6 oz.

The FE 135mm F1.8 GM includes a number of professional controls that enhance ease of operation for both stills and movie shooting. These include an aperture ring that allows direct, intuitive aperture control and a focus ring that features Linear Response MF for fine, responsive manual focus control. There is also a focus range limiter switch, two customizable focus hold buttons, and a focus-mode switch that makes it possible to quickly select auto or manual focus to match changing shooting conditions.

In addition to the new FE 135mm F1.8 GM Lens, Sony has also announced a new lineup of Circular Polarizing Filters. The new filters, including models for lens diameters 49mm, 55mm, 62mm, 67mm, 72mm, 77mm and 82mm, preserve image quality and resolution about twice [i] as effectively as Sony’s existing gsa 2016 new orleans circular PL filter lineup, making them a perfect partner for Sony’s flagship G Master series lens. They also feature a ZEISS® T* Coating to minimize flare and a slim filter design to prevent image vignetting and maximize overall performance.
