Canon U.S.A. Introduces New EF 50MM F/1.8 STM Lens

Compact and Lightweight EF Lens Features Stepping Motor (STM) Technology and is Ideal for First time DSLR Users as well as Advanced Amateur Photographers

MELVILLE, N.Y., May 11, 2015 - Canon U.S.A., a leader in digital imaging solutions, is proud to announce the new lightweight and compact Canon EF 50mm f/1.8 STM standard lens. Featuring a large maximum aperture of f/1.8, this single focal length lens (which has an effective focal length of 80mm when attached to an EOS camera with an APS-C sensor such as the EOS Rebel T6i) is ideal for creating portraits with beautiful, soft-blurred backgrounds. It's also ideal for low-light photography and night scenes. Now incorporating Canon's proprietary STM stepping motor technology, this new lens supports Canon's EOS Movie Servo AF* (autofocus) function to provide smooth and quiet continuous AF during video recording, as well as when capturing still photos.

"Canon's optical heritage of creating high-quality lenses is something we are very proud of ," said Yuichi Ishizuka, president and COO of Canon U.S.A., Inc. "Regardless of skill level or budget, all photographers and videographers should have access to superb creative tools that enable them to capture not only beautiful images but images that tell the story of their lives. This new Canon EF 50mm f/1.8 STM lens, will provide photographers and videographers with outstanding images they will want to share for years to come."

The new Canon EF 50mm f/1.8mm STM lens is excellent for entry-level and advanced amateur photographers, as well as users looking to capture video. Featuring an improved exterior design, including a new focus ring placement, it provides photographers with the most compact Canon EF 50mm lens ever, at just 1.5 inches in length. In addition, this new lens uses a metal mount providing additional stability and ruggedness compared to its predecessor.

Composed of six elements in five groups, the new Canon EF 50mm f/1.8mm STM lens features an optimized lens placement and Super Spectra Coating (SSC), translating into less ghosting and flaring than the previous model, while at the same time helping to enhance light transmission and optimize color reproduction accuracy. The new lens features a seven blade circular aperture, improved from the predecessor's five blade non-circular aperture, helping to deliver a more visually appealing blurring effect, and producing sharp images of subjects that truly stand out against beautiful, soft backgrounds. The minimum focusing distance for the lens has been shortened to 1.1 feet from 1.5 feet with a maximum magnification of 0.21x, allowing for more creative close-up photos and videos.

Pricing and Availability

The new Canon EF 50mm f/1.8mm STM standard prime lens is scheduled to be available by the end of May for an estimated retail price of $125.99.
