    Overview

    The Quantaray Tech-10 AF 70-300mm f/4-5.6 is a budget telephoto zoom lens, essentially a rebadged Tamron. It offers good sharpness across most of the range, though it softens at 300mm and exhibits noticeable chromatic aberration in high-contrast areas. Build is lightweight and compact, making it easy to handhold. Autofocus is quiet but not as fast as USM lenses, and it lacks image stabilization. It suits budget-conscious photographers seeking a telephoto for outdoor sports or macro (1:2 at 300mm).
