Tamron Offers Practicali­ty In New Mid-Range Zoom

-

Lens ‘exotica’ is very fashionabl­e at the moment, but Tamron has opted for a more sober approach with its new A043 model zoom for the Canon EF and Nikon F mounts. It’s a 35-150mm f2.8-4.0 Di series (for full35mm D-SLRs) zoom which spans medium wide-angle to short telephoto focal lengths, making it useful for a wide variety of applicatio­ns. The versatilit­y is enhanced by a compact and lightweigh­t design, a weathersea­led external constructi­on, built-in optical image stabilisat­ion – claimed to give up to five stops of correction for camera shake – and a minimum focusing distance of 45 centimetre­s across the full focal range.

The optical constructi­on comprises 19 elements in 14 groups which includes three with low-dispersion characteri­stics to minimise chromatic aberration­s and three hybrid aspherical types to correct for distortion. Tamron says that the 35-150mm’s optical performanc­e “…meets requiremen­ts of high resolution 50+ megapixel D-SLRs”. It should be noted here that the zoom can be used on Canon’s and Nikon’s full-35mm mirrorless cameras via the appropriat­e mount adaptors. Tamron’s BBAR (Broad-Band Anti-Reflection) multi-coating is used to help reduce both ghosting and flare. As part of the zoom’s weather protection measures, a fluorine coating is applied to the exposed surface of the front element to help repel moisture and grease, and enable easier cleaning.

The new 35-100mm zoom is the next lens to employ Tamron’s high-speed ‘Dual MPU’ microproce­ssor which handles both the autofocusi­ng and optical image stabilisat­ion operations. Autofocusi­ng adjustment­s are driven by an ‘Optimised Silent Drive’ (OSD) DC-type motor which is claimed to be quieter, faster and enable more precise control. Tamron says it also enables more reliable subject tracking. The lens is compatible with Tamron’s ‘TAP-In Console’ which allows for firmware upgrades and various adjustment­s, including to the focusing and optical image stabilisat­ion operations.

Weighing in at 790 grams (Nikon mount version), the Tamron 35-150mm has a nine-blade diaphragm to give smoother out-of-focus effects, and it accepts 77 millimetre­s diameter screwthrea­d filters. The minimum aperture range is f16 to f22. Tamron sees this lens being an ideal companion to its 17-35mm f2.8-4.0 Di OSD (Model A037) wide-angle zoom.

The Tamron 35-150mm f2.8-4.0 Di VC OSD zoom is available now in both mount versions at $1399. For more informatio­n visit www.tamron.com.au
