Tamron 17-35mm f/2.8-4 Di OSD (Nikon)

New anti-reflection coating: Perfect for backlit shots
A strong backlight often results in unwanted reflections in the lens. In developing the 17-35 mm f/2.8-4 Di OSD, Tamron has gone to great lengths to eliminate these aberrations using comprehensive, multi-stage simulation analysis. The optical construction has also been optimised and the overall imaging performance has been maximised. The BBAR coating (broad-band anti-reflection) results in high transmission and prevents ghost images and scattered light.

Extremely quiet autofocus
The autofocus motor has a newly developed OSD module (Optimised Silent Drive) that allows silent focusing. This makes the lens ideal for situations in which absolute silence is needed during photography. Because of the reaction speed of the AF, the high focusing precision and the outstanding performance when following a subject, you will never miss the perfect moment, even with moving subjects.

Perfect protection thanks to fluorine coating and weatherproof construction
The front lens has a water- and grease-repellent fluorine coating. This makes cleaning the lens surface easier and protects it from scratches and damage from dirt, dust, moisture and fingerprints. The seals in the lens provide additional protection from the weather when shooting outdoors.
