Most basic Canon EF telephoto without IS or USM, cheapest 300mm at zero cost — IS II version recommended.
The Canon EF 70-300mm f/4.5-5.6 is the most basic Canon EF telephoto zoom without IS or USM, providing 300mm reach at the absolute lowest Canon telephoto pricing. The lens uses a basic micromotor for autofocus and lacks any stabilisation.
The 70-300mm covers portrait through long telephoto with Canon EF autofocus. The basic specification — no IS, no USM — means the lens lacks the stabilisation and quiet focusing of more expensive alternatives, but provides the same focal length range.
Build quality is Canon's most basic telephoto with lightweight plastic construction. The lens provides functional 300mm reach for well-lit conditions where the absence of IS is less critical.
The EF 70-300mm f/4.5-5.6 offers the cheapest Canon EF telephoto at essentially zero used cost. The missing IS and USM significantly limit capability — the IS II USM version is dramatically more capable.
