I bought this lens to use on a series of adventure cruises to the high Arctic and Scottish Islands. I was torn between this and the 100-400 L zoom. This lens was lighter and had a constant aperture.

Lightweight; Rugged

Very sharp pictures - if your OK with no zoom, It is a great lens for a decent price. I would highly recommend.

Shoots sharp images; very quiet IS; great colour and contrast; 2X teleconverter; which provides plenty of manual focussing

No zoom

I've shot with a 30D for about 7 years and recently switched to a 7D. All my digital SLR experience has been with these APS-C cameras. I purchased the 300mm IS f4L as a way to get a little more magnification than the 70-200mm IS f4L that I already had.

Fast auto-focus; Superior build quality; image stabilization; size and weight; close-up capability; case tripod mount & built-in lens shade

Semi-sharp images, i.s; noise (clunking

I found my copy of this lens unacceptable...Soft wide open. The imaging stabilizing was very clunky as well (IS) -- I use to use these lenses back when I was shooting news and they were always decent...

Excellent build quality; Good contrast and colour rendition; Retractable lens hood a nice touch

AF a little slow for class of lens; Resolution may not be up to future sensors (although pixel race has now slowed

Canon EF 300mm f/4L IS USM, which replaced a similar model without Image Stabilization technology, is one of about half a dozen telephoto lenses in Canon's current lens lineup.

The Canon EF 300mm f/4 L IS USM Lens is another excellent lens in the Canon L Series . While it has enough focal length to feel long, this very-well-built lens remains relatively small and light. Image quality from the 300 f/4 L IS lens is excellent.
