Tamron 18-200mm F/3.5-6.3 Di III VC
All-in-one zoom designed for the Sony NEX (E-mount) series
Built-in stabilization enables easy handheld shooting from 18mm wide angle to 200mm full telephoto
Equipped with Tamron's acclaimed VC (Vibration Compensation), and thanks to its light weight and compact size, this lens allows easy handheld shooting of sharp images with no camera shake over a wide range of settings, from everyday snapshots to memorable travel scenes.
Stepping motor adopted for the AF drive, a construction that accommodates contrast-detection AF and shooting video.
The AF drive has a stepping motor that is optimal for the Contrast-detection AF system employed by NEX series cameras. This also gives the drive a quieter operation, which is ideal for shooting video in which voices are recorded. In addition, ease of operation is enhanced with the Direct Manual Focus (DMF) function, which allows the user to make fine manual adjustments after initially focusing by AF.
Striking appearance worthy of the NEX series design.
The metallic lens barrel exterior is available in two colors: black and silver.
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 Sony's NEX series 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.
About the VC (Vibration Compensation) system
Tamron's VC mechanism employs a three-coil system, where by 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 steep balls, achieving smooth movement with little friction. This provides a stable view finder image with excellent tracking performance that eliminates the blur from handheld shots for cleaner, crisper shots.
About the new VC mechanism (moving coil system)
Tamron's conventional VC (Vibration Compensation) unit has a moving magnet system with heavy magnets in the vibration-compensating lens. However, the new VC mechanism adopts a lightweight moving coil system that reduces the load on the drive system. This allows the drive to be operated with smaller coils and magnets, reducing the weight and size for the entire VC unit, In addition, improvements to software and other elements of the VC mechanism used in the 18-200mm Di III VC have made the mechanism even quieter.
Tamron is a leading manufacturer of photographic lenses. 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 catagory of lenses with the new 18-270mm Di II VC PZD - the world's smallest and lightest 15X zoom lens featuring Tamron's propietary VC (Vibration Compensation) system for blur-free hand-held shooting of photos in low light and at a telephoto settings and PZD (Piezo Drive) autofocus system for fast and quiet AF operation. Tamron has garnered international acclaim for its extensive line-up of professional and consumer lenses.
