If you're bringing only one lens to the shoot, make it this one. The Tamron 24–70mm f/2.8 is a fast, stabilized workhorse with beautiful image quality and a zoom range that covers everything from wide-angle scenes to tight portraits. It’s built for versatility, low-light situations, and smooth autofocus on Canon DSLRs. Oh—and that VC (Vibration Compensation)? It's broken :( but the lens still shoots as it should.
