Tamron SP 15-30 mm F / 2.8 Di VC USD G2 confirmed

Tamron SP 15-30mm F / 2.8 Di VC USD G2

Four years after the release of its popular SP 15-30 mm F / 2.8 Di VC USD optic, Tamron has given fans of wide-angle lenses a new object of desire in a Mark II update.

The SP 15-30mm F / 2.8 Di VC USD G2 (Model A041) will be the latest optic for the G2 suffix, according to the SP 24-70mm F2.8 Di VC USD G2 and SP 70-200mm F2.8 Di VC USD G2 that surfaced last year.

This lens of the second generation stays with the same basic idea as the original, and repeats even the 18 element, 13 group optical configuration. As a thin lens it is designed for users of full-frame Nikon and Canon DSLR cameras, with the main table being the combination of a wide viewing angle and a fast (and constant) maximum aperture .

The extra sweetener of vibration compensation has also been improved from the technology in the first version and now claims that it can compensate up to 4.5 stops.

Canon users also benefit from a rear mounted filter holder, which denies the use of huge (and expensive) filters for the spherical front element, while users of both Canon and Nikon versions benefit from nine rounded aperture blades to produce more attractive bokeh.

Three separate coatings

Wide-angle lenses are particularly sensitive to specific aberrations, but ghosting and flare must be minimized thanks to the application of a newly developed AX (Anti-reflection eXpand) coating. The purpose of this is to keep the reflection factor for peripheral areas of the lens the same as the central part, and it joins the eBand (Extended Bandwidth & Angular-Dependency) and BBAR (Broad-Band Anti-Reflection) Coatings used in the Mark 1 version to make a threefold attack on everything that could damage image quality.

The lens also promises to deliver "simply excellent" optical performance, thanks to an XGM (eXpanded Glass Molded Aspherical) lens, along with multiple LD (Low Dispersion) lens elements to combat distortion and lateral chromatic aberration, respectively.

Weatherproof design

Tamron has specially made the lens to the same sense of high quality and operability & # 39; to have as the aforementioned G2 lenses, with a weather-resistant design to prevent dust and moisture from creeping in.

The front element also features a fluorine coating on the front element, which is not only used to repel dirt, dust and moisture, but also promises to do this more effectively than the coating of the previous version.

Tamron thinks that the built-in Dual MPU (Micro Processing Unit) allows "greatly improved AF speed and precision", although it is unclear whether this is relative to other lenses or the previous version (which used the same unit). Anyway, this is again a collaboration with a separate processor to process vibration compensation.

The lens arrives only a few weeks after the company announced the 17-35 mm f / 2.8-4 Di OSD, a lens that is also designed for full-frame DSLR users.

Although Tamron has not announced an asking price for the new lens, Nikon users can get one on September 21, a few weeks earlier than the Canon version that arrives on October 12th. We will update this page with pricing information as soon as we have it.
