The new lenses are High Contrast and High Resolution Unrivaled in the Industry. Compatible with 1/1.7" imagers supporting 2.74μm pixel-pitch 6-mega (max) pixel resolution, with an approved highest-level resolution and contrast in Ø29mm machine-vision lenses. Tamron's state-of-the-art optics technology significantly reduces TV distortion compared with previous models. High-Quality Imaging in Close-up Shooting Distances. The new lens provides high-quality imaging in commonly used close-up distances. Thorough inspection is performed on the imaging resolution from the center to the periphery, delivering high-contrast and high-resolution without unbalanced blurring throughout the entire lens view. New Robust Design of Anti-Vibration and Anti-Shock Mechanism improves anti-vibration and anti-shock performance compared with previous models.
