Canon's USM kit zoom — basic 28-80mm with micro-USM motor for quieter AF than non-USM versions.
The Canon EF 28-80mm f/3.5-5.6 IV USM is a budget Canon kit zoom with micro-USM motor — quieter than the non-USM versions. The Mark IV indicates this is a late revision. Commonly bundled with entry-level EOS film and early digital bodies.
Optically basic — acceptable centre sharpness only. Variable f/3.5-5.6. The micro-USM provides quieter AF than the DC motor in non-USM versions but lacks the full-time manual override of ring-type USM. No image stabilisation.
Canon EF mount with 58mm filter thread. Approximately 200g — lightweight. Full-frame coverage. Plastic construction. The USM designation is the only meaningful advantage over non-USM Mark versions.
Essentially free used. Any modern zoom is dramatically better. The USM motor is slightly quieter than DC. For use only at throwaway prices. Multiple similar Canon 28-80mm variants exist — they're all basic.
