Alongside the super-fast a6300, Sony has released details of a new, ultra-high-resolution lens lineup optimized for its full-frame E-mount cameras: the G Master series. Starting off with a collection of much desired focal lengths and apertures from 24 to 200mm, almost all the bases are covered. This includes the mid-range FE 24-70mm f/2.8 GM zoom, a near-perfect FE 85mm f/1.4 GM portrait prime, and a telephoto staple in the form of the FE 70-200mm f/2.8 GM OSS. Further enhancing the E-mount lens selection, there are also an FE 1.4x Teleconverter and FE 2.0x Teleconverter for the 70-200mm GM that will boost the focal length for even farther reach.
Sony FE 24-70mm
Shared among all of the G Master series lenses are goals of outstanding resolution, set at a baseline of 50 line pairs per millimeter when shot wide open, and soft, exceptionally pleasing bokeh, much like the original G series. Helping to ensure this incredible resolution is the development of the XA, or extreme aspherical, lens element. Each of these is designed with better than 0.01-micron precision, and coatings, such as Sony’s Nano AR Coating, can be accounted for in simulations to guarantee performance. This also means that the lenses will be perfectly compatible with any future high-resolution sensor advancements. These XA glass elements contribute to bokeh performance, as well, thanks to their precise design, and minimize spherical aberrations to balance sharpness and bokeh.
Starting off with the classic do-everything lens, the FE 24-70mm f/2.8 GM, users will find a super–sharp lens with a wide aperture for working in a vast range of situations. It manages this edge-to-edge resolution by employing three aspherical elements, including one XA, one Extra-low Dispersion, or ED, element, and one Super Extra-low Dispersion element that work to reduce all types of aberrations and, when combined with the Nano AR Coating, create an image of high clarity and contrast. The lens also sports a nine-blade circular aperture for smooth bokeh and a Direct Drive Super Sonic wave Motor (DDSSM) that will lock focus quickly and precisely. As befitting a lens of this caliber, Sony has built the G Master series for professional use with a rugged dust- and moisture-resistant body, physical AF/MF switch and focus hold buttons, and a zoom lock. This lens will easily fulfill a variety of purposes, from wide-angle landscapes to tight portraits, with ease.
Sony made sure to deliver something many considered missing from the E-mount lineup when it created its fast portrait prime: the FE 85mm f/1.4 GM. It has one of the most preferred focal lengths for portraiture, a super-fast f/1.4 aperture for super-shallow depth of field, and is built to handle the demands of a professional work environment. Optimized for wide-open performance, it is exceptionally sharp at f/1.4, due to the use of one XA element and three ED elements. When stopped down, the lens is designed for bokeh perfection, with an 11-blade circular diaphragm that will maintain pleasing out-of-focus areas. It also features Sony’s Nano AR Coating and is equipped with a ring drive SSM system for smooth, precise focusing with the lens’s large optics. This motor is even equipped with two position sensors to ensure maximum precision during use. With a durable, weather-resistant build, the lens will hold up in adverse conditions and the body also has an AF/MF switch, focus hold button and, for video shooters, an aperture ring with a click/declick switch, much like the FE 35mm f/1.4 ZA.
Moving up the focal length ladder, we encounter the FE 70-200mm f/2.8 GM OSS, a telephoto zoom that will find its way into many shooters’ bags. It maximizes sharpness and bokeh much like the other G Master lenses, using a combination of three aspherical elements, including one XA, four ED lenses, two Super ED glass elements, and the Nano AR Coating alongside an 11-blade circular aperture. Key to this telephoto range is fast, accurate autofocus granted by a ring drive SSM system for the large front-focusing group and a double linear motor for the rear focus group, which combine to impressive speed and precision. It also has built-in image stabilization for enhanced performance with slower shutter speeds and at longer focal lengths and the ability to use 5-axis stabilization with compatible bodies. Close-up performance is also benefitted by a minimum focus distance of 3.14' and a floating focus mechanism. The barrel of the lens is designed for speed with a focus hold button, focus range limiter, AF/MF switch, OSS on/off switch, and OSS–type switch that grant tactile control. And, of course, it is weather resistant, with a fluorine coating on the front element. A bonus for this lens is the incorporation of a removable, rotating tripod mount for rapid setup and easy transport.
If you need longer focal lengths, Sony has created the first dedicated teleconverters for the E-mount system, though more specifically for the 70-200 G Master lens. The FE 1.4x Teleconverter and FE 2.0x Teleconverter maintain high lens performance while boosting the lenses’ focal lengths to 98-280mm and 140-400mm, respectively. The teleconverters retain full AF precision and speed while also recording EXIF data to files. They feature the same dust- and moisture-resistant design as the lens for optimal performance in all conditions. While only compatible with the FE 70-200mm f/2.8 GM OSS lens at the moment, select future lenses may be supported.
