Canon EF 300mm f/4L USM

Blending a versatile telephoto focal length with a modest form factor, the EF 300mm f/4L IS USM is a long-reaching prime and member of Canon ‘s elite L-series of optics. Two ultra-low dispersion elements are used to significantly reduce color fringing and chromatic aberrations in order to achieve a high degree of clarity, and a Super Spectra coating has also been applied to maintain contrast and color fidelity when working in difficult lighting conditions.
