Tamron today announced the price and availability of its 18-200mm F/3.5-6.3 Di III superzoom lens for the Canon EOS M compact system camera. Originally released for Sony mount in 2011, this 29-320mm equivalent lens employs two (Low Dispersion) elements, three Molded-Glass Aspherical elements, one XR (high refractive index) element, and one Hybrid Aspherical element to reduce aberrations "to a bare minimum" as Tamron put it. The lens also has optical vibration compensation and a stepping motor adopted for the AF drive, a construction that accommodates contrast-detect auto focus and movie shooting. This feature also supports the Direct Manual Focus (DMF) function, which allows the user to make fine manual adjustments after initially focusing by AF. The Tamron 18-200mm F/3.5-6.3 Di III VC for Canon will be available in the US starting 26 June 2014 priced at $499.
Tamron Press Release
Announcing the Canon mount of Tamron's 18-200mm ALL-IN-ON zoom exclusively for mirrorless interchangeable-lens cameras with APS-C sized sensors
18-200mm F/3.5-6.3 Di III VC (Model B011)
June 19, 2014,Commack, New York - Tamron USA, Inc. announced the price and delivery of the 18-200mm F/3.5-6.3 Di III VC for Canon mount (Model B011). This lightweight, compact high-power zoom lens, originally released for Sony mount in 2011, is designed for mirrorless interchangeable-lens cameras with APS-C sized sensors and sports a stylish design and is available in two color options. It will be available in the U.S. starting June 26, 2014 at $499.
- This high-power, 18-200mm, lightweight and compact zoom lens weighing 16.2 ounces with a 62mm filter is designed for mirrorless interchangeable-lens cameras. Equipped with Tamron's acclaimed VC (Vibration Compensation), the lens enables easy handheld shooting from 18mm wide angle to 200mm full telephoto.
- Employing two (Low Dispersion) elements, three Molded-Glass Aspherical elements, one XR (high refractive index) element, and one Hybrid Aspherical element, the lens delivers astounding image quality by reducing aberrations to a bare minimum.
- The lens boasts a striking appearance worthy of mirrorless interchangeable-lens camera designs. The metallic lens barrel exterior is available in two colors: black and silver.
- The lens also has a stepping motor adopted for the AF drive, a construction that accommodates Contrast-detection AF and shooting video. This feature also supports Direct Manual Focus (DMF) function, which allows the user to make fine manual adjustments after initially focusing by AF.
 "Mirrorless interchangeable-lens cameras" are also known as "Compact System Cameras."
 Di III (Digitally integrated design): A designation Tamron gives to lenses engineered specifically for mirrorless interchangeable-lens cameras with no internal mirror box or pentaprism, adopting an optical design that matches the characteristics of the digital camera. (Note: These lenses cannot be used with digital SLR cameras with built-in mirror box or conventional 35mm film SLR cameras).
 Specifications, appearance, functionality, etc. may be changed without prior notice.
 Length is the distance between the front tip of the lens and the mount face.
About the stepping motor
The B011's autofocus mechanism uses a stepping motor that is an ideal match for the Contrast-detection AF system used in mirrorless interchangeable-lens cameras. The stepping motor's actuator allows finely tuned control of angular rotation, and since it drives the focusing mechanism directly without an intermediate reduction gear, it also provides superbly quiet performance.
VC (Vibration Compensation)
Tamron's VC mechanism employs a three-coil system, whereby three driving coils activate the shake-compensating VC lens group electromagnetically via three steel balls. The VC lens elements are held in place only by contact with the steel balls, achieving smooth movement with little friction. This provides a stable viewfinder image with excellent tracking performance that eliminates the blur from handheld shots for cleaner, crisper shots.
"New Eyes for Industry" is Tamron's philosophy. This creed is consistent with the company's position as a comprehensive manufacturer of a wide range of original optical products, from interchangeable lenses for SLR cameras to various optical devices for both the general consumer and OEM. Tamron makes optical products that contribute to a range of different industries and will continue to devote its rich creativity and leading-edge technical prowess to various industrial fields. Furthermore, Tamron is fully aware of its responsibility to the environment and aspires to help preserve the natural environment in all of its business activities. Among its many optical and mechanical innovations since the founding of the company in 1950, Tamron's development of mass-produced hybrid Aspherical elements paved the way for today's compact high power All-In-One™ lenses when, in 1992, this technology was incorporated into the ground-breaking 28-200mm. Tamron continues to lead in this category of lenses with the newly announced 16-300mm Di II VC PZD Macro - the world's only 18.8x All-In-One™ zoom lens featuring Tamron's proprietary VC (Vibration Compensation) system for blur-free hand-held shooting of photos in low light and at telephoto settings and PZD (Piezo Drive) autofocus system for fast and quiet autofocus operation. Tamron's recent SP (Super performance) lens introductions have received accolades and high praise from leading photographic magazines and websites for their outstanding best-in-class performance. Tamron has garnered international acclaim for its extensive line-up of professional and consumer lenses.
