Additional information:

The Canon EF 300 mm f/ 4 L IS USM  is a compact professional L-series fast telephoto prime lens  for Canon EOS digital and film cameras. 

It features a good price-quality relationship.

Equivalent focal length for APS-C cameras:   480 mm.

The built-in 3-stop image stabilizer makes it possible to shoot in low-light-level conditions at shutter speeds up to 1/60.

The aperture has eight blades.  The lens produces beautiful, soft and flexible bokeh when wide open.

The lens features a convenient in use built-in retractable hood.

The lens has the shortest minimum focusing distance in its series, which makes it possible to fill the frame with a small  subject (for example, a little bird). You can take pictures of insects from quite a long distance without scaring them away.

The Canon EF 300 mm  f/ 4 L IS USM produces a very sharp image from f/4.0. There is slight vignetting at this aperture.

The optical scheme includes two UD glass elements (2nd and 5th), which minimizes aberrations and has a positive effect upon contrast and color rendering. These lenses are ground out of individually-grown soft crystals of optical fluorite.

The  Canon EF 300 mm  f/ 4 L IS USM lens  is well resistant to back and side light, especially with a built-in  hood.

Focusing is internal. The front lens does not rotate, which enables the use of a polarizing or gradient filter.  Manual adjustment of sharpness is possible at any time by turning the focus ring.

Color  rendering is natural, colors are saturated. Contrast of images is high.

The built-in ultra-sonic motor makes focusing very fast and silent.  The lens provides steady focusing in poor lighting conditions.

The Canon EF 300 mm f/ 4 L IS USM is perfectly fit for shooting animals, wild life, remote fragments and sporting events, as well as for photojournalism. It is better to use it with full-frame sensors.

The lens is compatible with  Canon extenders:   EF 1.4X and EF 2.0X.

It performs very well with the 1.4x converter - 420 mm at f/5.6 with stabilization functions maintained.
