Tamron SP 11-18mm f/4.5-5.6 DI II APS-C Lens for Canon EF-S Mount Review

The Tamron SP 11-18mm f/4.5-5.6 Di II is an ultra-wide-angle zoom designed for Canon APS-C DSLRs with EF-S mount. Its 11-18mm focal range (equivalent to roughly 17-28mm on a full-frame camera) makes it a solid option for landscape, architecture, and interior photography where you need maximum coverage. The variable f/4.5-5.6 aperture is typical for budget ultra-wides, though it limits low-light performance and background separation compared to faster glass.

This particular listing is a used unit in excellent condition from KEH, priced at $86. That's an attractive entry point for shooters looking to add ultra-wide capability without investing in pricier options like Canon's 10-18mm STM or third-party f/2.8 zooms. The 77mm filter thread is notably large for a lens of this class, which could mean added expense for filters. Build quality and autofocus speed are generally modest on older Tamron models like the A13, so expectations should match the price. For Canon APS-C users on a budget who need ultra-wide reach and are comfortable buying used, this lens delivers functional coverage at a very low cost.
