While you were out, the digital-only superzoom got more super. Tamron, originator of the superzoom lens more than a decade ago, ups the ante with its new 18-250mm f/3.5-6.3 optic — boasting the industry’s broadest zoom range, at nearly 14X (13.9X). A 28-388mm equivalent, it adds 50mm to the tele end and does so at no cost of weight, dimension, or optical performance over Tamron’s 18-200mm f/3.5-6.3 lens (which remains in Tamron’s catalog). Only the price is higher: at $499 (street), vs. $390 for the shorter lens.
An impressive optical achievement, the industry’s first 13.9X digital-only zoom hits a trifecta by expanding zoom range, utility, and optical performance.
18-250mm (18.52-238.11mm tested), f/3.5- 6.3 (f/3.26-6.86 tested), 16 elements in 14 groups. Focusing turns 55 degrees counterclockwise. Zoom ring turns 80 degrees counterclockwise. Focal lengths marked at 18-, 35-, 50-, 70-, 100-, 200-, and 250mm.
