Sony – New full-Frame 135mm F1.8 G Master Prime Lens

Although other camera makers have jumped into the full-frame mirrorless camera market, Sony has been at the forefront in building out its full-frame mirrorless system, as is evident today in its announcement of a new telephoto prime lens: Today, Sony introduced its 135mm F1.8 full-frame, large-aperture telephoto prime lens (model SEL135F18GM), which is a new G Master-series full-frame E-mount interchangeable prime lens. The FE 135mm F1.8 GM will ship in late April 2019 for approximately $1,900.

According to Sony, the lens has “exceptionally high resolution and exquisite bokeh, two qualities that are signature attributes of Sony’s flagship G Master brand.” Sony says the lens will also combine “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.”

  • The lens has a compact, lightweight body that weighs 33.6 oz.
  • It has an aperture and a focus ring, plus a focus-range limiter switch, two customizable focus-hold buttons and a focus-mode switch to quickly select auto or manual focus.
  • It has an optical design that places XA (extreme aspherical) and super ED (Extra-low Dispersion) glass elements in the front group to suppress common telephoto lens aberrations.
  • The super ED element plus one ED glass element are positioned to compensate for axial chromatic aberration, minimize color fringing and maximize overall resolution.
  • Sony’s Nano AR Coating is applied to reduce flare and ghosting, particularly when shooting backlit portraits.
  • The lens has an 11-bladed circular aperture mechanism and also features dual-autofocus groups in a floating focus arrangement for improved close-up capability
  • There are four XD linear motors—two for each group—that achieve rapid, reliable and speedy AF tracking and performance for action shots.
