INSUBCONTINENT EXCLUSIVE:
Four years after the release of its popular SP 15-30mm F/2.8 Di VC USD optic, Tamron has given wide-angle aficionados a new object of desire
with a Mark II update.The SP 15-30mm F/2.8 Di VC USD G2 (Model A041) becomes the latest optic to be bestowed with the G2 suffix, following
basic idea as the original, even repeating its 18-element, 13 -group optical configuration
As a 'Di' lens, it's been designed for users of full-frame Nikon and Canon DSLRs, with the main draw being its combination of a wide angle
of view and a fast (and constant) maximum aperture.The additional sweetener of Vibration Compensation has also been improved from the
rear-mounted filter holder, which negates the use of massive (and costly) filters in front of the bulbous front element, while users of both
Canon and Nikon versions benefit from nine rounded diaphragm blades to help produce more attractive bokeh.Three separate coatingsWide-angle
lenses are particularly susceptible to specific aberrations, but ghosting and flare should be minimized thanks to the application of a newly
developed AX (Anti-reflection eXpand) coating
This aims to keep the reflection factor for peripheral areas of the lens the same as he central portion, and it joins the eBand (Extended
Bandwidth Angular-Dependency) and BBAR (Broad-Band Anti-Reflection) Coatings used in the Mark 1 version to form a three-pronged assault on
anything that might mar image quality.Tamron also claims the lens will deliver "simply outstanding" optical performance courtesy of an XGM
(eXpanded Glass Molded Aspherical) lens, together with multiple LD (Low Dispersion) elements to combat distortion and lateral chromatic
aberration respectively.Weather-resistant designTamron has specifically crafted the lens to have the same "feel of high quality and
has also been primed with a fluorine coating, which is not only said to help repel dirt, dust and moisture, but promises to do so more
AF speed and precision", although whether this is relative to other lenses or the previous version (which employed the same unit) is unclear
company announced the 17-35mm f/2.8-4 Di OSD, a lens that's also been designed for full-frame DSLR users.While Tamron hasn't yet disclosed
a price for the new lens, Nikon users will be able to get their hands on one on September 21, a few weeks ahead of the Canon version, which
will arrive on October 12
We'll update this page with pricing information as soon as we have it.ARJoZDFvgDNSMSdQ9dVdHV.jpg#
