Sony has announced two new lenses for their full-frame E-mount cameras: a premium “bokehlicious” 100mm f/2.8 G Master lens, and a compact 85mm f/1.8. Both Sony FE Prime lenses are available for pre-order and will ship in March. Sony 100mm f/2.8 STF G Master lens – made for “bokeh lovers” The first of the new Sony optics is the 100mm f/2.8 STF G Master OSS lens. The name of this mid-telephoto prime lens already proclaims it belongs to Sony’s premium G Master line, but what’s special about this glass is the apodization element marketed as “STF – smooth transition focus”. It is basically a circular gradient ND filter which helps create exceptionally smooth bokeh but does not affect the subject in sharp focus, creating a much smoother transition between areas in and out of focus. This filter element, however, reduces the amount of light coming in through the lens, and results in a T-stop of T5.6 when wide open at f/2.8. Sony claims that despite having this filter inside the lens, vignetting is kept to a complete minimum. Apodization element inside of Sony FE 100mm lens.

There is also a macro ring switch for changing focusing distance, allowing up to 0,25x close-up shooting. Other features of the Sony 100mm f/2.8 GM lens include: ED and aspherical elements to reduce aberrations Nano AR Coating to limit flare and ghosting Fast and silent focusing through an SSM motor Optical StadyShot image stabilization Dust and moisture resistance Programmable focus-hold button Physical aperture ring for manual control Sony FE 85mm f/1.8 lens Sony’s second announcement is a cheaper full-frame E-mount lens. It is the Sony FE 85mm f/1.8 lens, a much more compact product than the GM 100mm lens (700 grams vs 371 grams). This piece of glass sports a 9-blade circular aperture, as well as an ED element to minimize aberrations. It features a programmable focus-hold button too, but has no stabilization. It extends Sony’s affordable full-frame primes line along with the existing FE 28mm f/2 and FE 50mm f/1.8. Bokeh comparison 100mm (left) and 85mm (right).

It’s been a busy day for Sony’s Press Centre. On top of announcing the new A6300, they’ve also introduced their brand new line of interchangeable lenses: the G Master range. Included are three new E-mount, full frame lenses. The three lenses announced today include a 24-70mm constant F2.8 standard zoom, an 85mm F1.4 telephoto prime and a 70-200mm constant F2.8 telephoto zoom. G Master 24-70mm F2.8 (SEL2470GM) This lens features three aspherical elements, one of which is a new to market XA (extreme aspherical) which is said to reduce aberration while allowing the entire zoom and aperture range to maintain the highest resolution possible. The other two, the ED (extra dispersion) and Super ED elements are designed to keep chromatic aberration down while avoiding unnatural bokeh. The SEL2470GM features a Nano AR coated, 9-bladed aperture that’s designed to remain circular in all settings, designed to suppress reflections. A new algorithm has been introduced for the SSM, allowing quick and accurate positioning of all lens elements.

The 85mm lens also features the most blades ever used on a single lens—a total of eleven—designed to ensure smooth bokeh, as well as an external Nano AR coating to reduce flare. This telephoto prime lens also features a ring drive SSM and two position sensors, all working in conjunction to control the lens’ heavy hardware.

It also packs an external Nano AR coating. The FE 70-200mm holds a floating focus system, the first of its kind to be included in a zoom lens, providing a minimum focusing distance of 0.96—and ensuring optimal performance during photography and filmmaking. Featured again is an SSM, working in conjunction with dual linear motors to shift large lens elements quickly and accurately. Also built in is Optical SteadyShot image stabilization and a rotating tripod mount.

G Master Range Pricing and Availability The FE 24-70mm F2.8 and 85mm F1.4 lenses will be available in Europe from March 2016, priced around €2,400 and €2,000, respectively. The G Master FE 70-200mm F2.8 Telephoto Zoom lens, and its teleconverters are due to be released in May 2016 and pricing has yet to be confirmed. Visit Sony’s Press Centre for the full release.
