Tamron 17-35mm F/2.8-4 Di Osd Nikon

By | 01/11/2022

Tamron has introduced its 17-35mm F2.8-4 Di OSD lens for total-frame Catechism and Nikon bodies. This compact lens, which weighs simply 460g (16.2oz), features 15 elements, including low-dispersion and glass-molded aspherical elements. Both ‘BBAR’ and fluorine coatings are employed, with the latter helping to fingerprints and wet from adhering to this weather condition-sealed lens. The Optimized Silent Drive motor promises ‘fantabulous AF speed and drive noise reduction,’ according to Tamron.

The 17-35mm F2.8-four Di OSD will be available in early September for Nikon FX bodies, with a Canon EF model to follow later. Information technology will be priced at a very reasonable $599.

Tamron Announces the Smallest, Lightest Ultra-Wide-Angle Zoom Lens in its Grade

A sophisticated balance of outstanding eyes and matchless mobility

August six, 2018, Commack, New York— Tamron announces the launch of a new ultra-wide-angle zoom lens, the 17-35mm F/ii.8-4 Di OSD (Model A037), for 35mm full-frame DSLR cameras. The vision backside the Model A037 is that of an ultra-wide-angle zoom lens that has a separate concept from SP xv-30mm F/2.8 Di VC USD (Model A012), with superb image quality and easy portability. At just 3.5 in in length and 16.2 oz. in weight, it is the smallest and lightest in its class. The focal length ranges from an ultra-wide 17mm that is suitable for professional mural photography to a standard 35mm perfect for snapshot photography. As for F-stops, the wide-angle end is a large discontinuity F/2.8, and at the telephoto cease is a fast F/4. The Wet-Resistant Construction and Fluorine Blanket help to enhance the user’southward photographic experience. For those looking to effort out an ultra-wide-angle zoom lens for the get-go time, equally well as having a lens that is easily portable, the A037 is the definitive choice. The lens will be bachelor in Nikon mount on September 4, 2018 at a suggested retail cost of $599. The launch of the Catechism mount model will be announced at a subsequently date.

PRODUCT HIGHLIGHTS

1. High-performance imaging for shooting vast landscapes in sharp particular

The optical structure (xv elements in x groups) uses four LD (Depression Dispersion) lens elements to minimize axial chromatic aberrations that can occur with ultra-wide-angle zoom lenses. With two properly positioned GM (Glass Molded Aspherical) lenses, distortion and other abnormality can be satisfactorily corrected equally well. Being the smallest and lightest in its class and defended to high quality imaging, the engineers take paid particular attention to size. The lens has as well been advisedly designed to permit peripheral point image reproducibility and thereby facilitate a high degree of sharpness and contrast. The Minimum Object Distance (MOD) for the entire zoom range is a brusk 11 in., so background blurring is notwithstanding possible when opening the aperture and budgeted the subject close-up with this ultra-wide-angle zoom.

ii. Avant-garde blanket engineering science along with proprietary ghosting assay simulation applied science enabled the loftier level of backlighting control

Resistance to backlighting is extremely important for broad-angle lenses as they are oft subjected to strong calorie-free sources. The Model A037 has a high level optical construction that repeatedly employs comprehensive ghosting analysis simulation. The BBAR (Broad-Band Anti-Reflection) Coating is highly constructive in reducing reflection, assuasive ghosting and flare throughout the unabridged zoom range to exist controlled.

3. OSD (Optimized Silent Drive) enables both excellent AF speed and drive dissonance reduction

The AF drive organisation employs an OSD (Optimized Silent Bulldoze) to ensure quiet operation. Through the innovative optimization of the system that includes AF system speed reduction gear, Tamron could greatly reduce the drive noise in comparison to conventional AF types with built-in DC motors. AF performance and speed have also been vastly improved. Thus, even if silence is required, AF can be employed without having to worry at all near racket creation. The Model A037 can provide tiptop AF precision for verbal focus even when shooting moving objects, as well as outstanding trackability.

4. Circular aperture to produce a smooth-edged bokeh

A 7-blade diaphragm is configured to retain a smooth, circular-shaped aperture opening fifty-fifty when stopped down by 2 stops from the broad-open aperture. This produces a smooth-edged bokeh in background low-cal spots and avoids rugged aperture geometry.

five. Moisture-Resistant Structure

Seals are located at the lens mountain surface area and other critical locations to prevent infiltration of wet and/or rain drops to provide Moisture-Resistant Construction. This feature affords an additional layer of protection when shooting outdoors under adverse weather condition conditions.

6. Fluorine Coating

The surface of the front end element is coated with a protective fluorine compound that has excellent water- and oil-repellant qualities. The front surface is easier to wipe clean and is less vulnerable to the dissentious furnishings of dirt, dust, moisture or oily fingerprints, allowing for much easier maintenance. The coating also provides an enhanced level of durability, and will sustain its effectiveness for years.

vii. Compatible with TAMRON TAP-in ConsoleTM, an optional accessory

The new A037 is compatible with the optional TAMRON TAP-in Panel, an optional accompaniment product that provides a USB connection to a personal computer, enabling users to easily update a lens’due south firmware as well as customize features including fine adjustments to the AF.
