Tamron AF 11-18mm f/4.5-5.6 Aspherical LD Di II SP [IF] (5-Pin) Lens for Nikon F-Mount Review

The Tamron AF 11-18mm f/4.5-5.6 Di II SP is an ultra-wide-angle zoom designed for Nikon APS-C DSLRs. With an effective field of view equivalent to roughly 16-27mm in full-frame terms, it caters to landscape, architecture, and interior photographers who need expansive coverage without breaking the bank. This particular listing appears to be a used unit in excellent-plus condition from KEH, priced at $53, making it an affordable entry into ultra-wide photography for crop-sensor shooters.

As an older design, the lens features aspherical and low-dispersion elements to control distortion and chromatic aberration, along with internal focusing. The variable f/4.5-5.6 aperture is typical for budget ultra-wides but limits low-light flexibility. The 77mm filter thread is notably large for a lens of this class. For Nikon F-mount users still shooting DX-format bodies, this represents a budget-friendly way to explore ultra-wide angles, though newer options may offer better optical performance and build quality.
