Optical construction for clear images

Tamron designed the optical formula with 12 elements in 10 groups. The layout includes XLD (eXtra Low Dispersion) and LD (Low Dispersion) elements to control chromatic aberration. In addition, BBAR-G2 coating reduces ghosting and flare, helping to deliver clear images even in backlit or high-contrast scenes.

At the moderate telephoto end, the lens is useful for everyday snapshots and creative compositions, producing smooth and pleasing background rendering when appropriate. Overall, the focal range supports a variety of creative applications for both stills and video.

The RXD motor is suitable for both still photography and video recording due to its low-noise performance.
