Canon EF 300mm lens The EF 300mm lens refers to four telephoto prime lenses made by Canon. The lenses have a EF type mount which fits the Canon EOS line of cameras. When used on a digital EOS body with a field of view compensation factor of 1.3x, such as the Canon EOS-1D Mark III, it provides a narrow field of view, equivalent to a 390 mm lens mounted on a 35mm frame body. With a 1.6x body such as the Canon EOS 400D, it provides a narrower field of view, equivalent to a 480 mm lens mounted on a 35mm frame body. This lens is most commonly used by sports and wildlife photographers, but is short enough to be use for extreme close-up portraits. Because of its rather high native magnification, it can be used for some macro type photography. Cheapest price: $935 (across 1 store) Read Reviews Compare Prices Similar Lenses Write a Review
Canon EF 300mm excells 01/02/2010 Having had the Sigma f4.5-5.6 120-400mm lens for over a year , i decided to bite the bullet and purchase the Canon EF 300mm f/4 L IS USM for it's quality and it hasn't failed on that .This was something i lost between 300-400mm focus on the Sigma lens , you can alway crop your photos and the sharpnest is not lost with the Canon 300mm lens and works perfectly in low light. It's also a lot lighter on the arm tham the sigma 120-400mm if you are not using a Tripod or Monopod . It also come with its own attached hood and tripod mount ring, thus saving some money their also compared to other Canon L Lens. By Andrew Mccubbin Scotland				10/10
Great 300mm prime lens 29/07/2010 The Canon EF 300mm f4/L IS was one of Canon's first image stabilized lenses, and as a result, it is a little slower than newer IS lenses. The image stabilization has two modes -- one for tripod use and one for hand holding. The picture quality is fantastic, coming out of this lens, and it is lighter weight than the Canon EF 300mm f/2.8L IS USM for a fraction of the price. Attaching this lens to the 1.4X II Extender effectively makes the lens equivalent to 420mm f/5.6, while still retaining autofocus capability. With the Canon EF 2X II Extender, the lens loses autofocus, but is effectively a 600mm f/8 lens. I was a bit hesitant at first, wondering if I should just save up for the 300mm f/2.8L instead, but with such great image color and quality coming from the f/4L, my worries subsided. The lens hood of the 300 f/4L IS is retractable, and fits snugly while still allowing the use of the focus ring. This lens is not for everyone, as a 300mm prime gets you up close and personal with whatever subject you are shooting; the autofocus can sometimes slip from subject to something in the foreground. It does seem suitable for macro photography with the caveat that one maintains at least 0.3 meters (about a foot away) in order to take the picture. By Michael Huang Mountain View, CA				10/10
Compact wildlife lens 26/06/2010 Incredible IQ in a compact, hand-holdable, image stabilized lens. I have used 100-400 as well, while the zoom offers flexibility, this lens is a class apart in sharpness. IQ difference between the zoom and prime is amplified at subjects over 50m make it a perfect lens for wildlife.. 300mm F4L IS and 10-22mm are the only reasons I still shoot with Canon (rebel and 4/50D have poor ergonomics), and probably will be adding a new body to go with each, this is also the reason my D90 in mothballed (I was hoping Nikon will release a VR version when I switched to Nikon).
