300mm · f/4
The Sigma AF 300 mm f/4 APO Macro HSM is praised for excellent sharpness, especially at f/8, and good depth of field. Its main weakness is a too-short built-in lens hood, and older copies may have compatibility issues with newer Canon digital cameras. Build and handling are not extensively discussed, but the lens is noted as quite cheap and of excellent quality. It suits budget-conscious photographers seeking a sharp, macro-capable telephoto, though those needing longer reach may prefer a 400 mm f/5.6 version.
