Canon EF 300mm f/4L IS USM Telephoto Lens for Canon SLR Cameras Review

Bought the 300 f/4 thought it would be a good addition since it was light and image quality was good.

Got tired of it pretty quick though. F/4 just isn't wide enough for what I wanted to do.

Also as an owner of the 400 f/2.8, I got spoiled because few lenses out there can compete with it.

Sold the lens, bit the bullet and bought the 300 f/2.8.

Now that's a lens that can compete with the 400 f/2.8 in image quality.

Yes the 2.8 is 4x the price of the 4.0, but it's easily 4x the image quality.

Canon EF 300mm f/4L IS USM Telephoto Lens for Canon SLR Cameras Overview

Compact L-series telephoto lens with an Image Stabilizer, which compensates for camera shake with the equivalent effect of a shutter speed two stops faster. Two Image Stabilizer modes are provided: Stabilizer Mode 1 (the same mode featured on the EF 75-300mm f/4-5.6 IS USM) and the new Stabilizer Mode 2, which steadies the image during horizontal or vertical panning. Mode 2 detects the panning direction automatically. The closest focusing distance is 4.9 feet (1.5 m).
