Tamron, known as one of the most successful 3rd party lens manufacturer … and also for its infamous long … long naming convention for its lenses have just launched another acronym for their lenses! It’s USD! For those who wants a short de-acronym of this Tamron lens:
- SP = Superior Performance
- VC = Vibration Control (Nikon’s VR, Sigma’s OS, etc)
- USD = Ultrasonic Silent Drive (Canon’s USM, Sony’s SSM, etc)
Tamron’s press release:
March 9, 2010, Saitama, Japan – President and CEO Morio Ono of optical equipment manufacturer Tamron Co., Ltd., announced another advance in their pursuit of high resolution images in the telephoto lens category with the development of a 70-300mm F/4-5.6 telephoto zoom lens featuring image stabilizer - VC (Vibration Compensation) and an ultrasonic auto-focus drive – USD (Ultrasonic Silent Drive). The SP 70-300mm F4-5.6 Di VC USD high-resolution DSLR telephoto zoom lens has been produced for the Nikon mount, with the development of compatible mounts for Canon and Sony to follow.
While this new lens is designed for digital SLR cameras, it can be used with both full-frame sensor and AF 35mm cameras with a zoom range of 70-300mm; or with APS-C sensor cameras where the angle of view will change the zoom range equal to 109-465mm.
One thing to note is that the Sony mount (or Alpha mount) version will not include the VC as there isn’t a need. This I assume will mean that it will be priced a tad cheaper?
Of course, the other interesting thing to note is that instead of saying Nikon and Canon versions will be announced followed later by Pentax and Sony, they now launch their new lens with Nikon followed by Canon and Sony mentioned in the same breath! Hmmphhhh …
By the way, it’s Tamron’s 60th Anniversary this year … for full press release, go to Tamron’s website.
