Canon’s EF 800mm f/5.6L IS USM; Super Telephoto Power Page 2
Inside, you’ll find 18 elements in 14 groups, which includes two fluorite elements, one UD element, and one Super UD glass element for the correction of color fringing and the enhancement of contrast and sharpness. The lens uses a standard 52mm drop-in filter holder, can autofocus with a 1.4x tele-converter using the camera’s center focusing area (the 2x can be used with manual focus only), and Canon extension tubes can also be used.
Out in the field, the Canon EOS-1D Mark III and its AI Servo kept everything in focus. If I did my part and locked onto a subject, it stayed locked on! Since the eagles at Blackwater Refuge land on special platforms and dead trees away from the general public, the 800mm f/5.6L IS USM was a pleasure to use. When shooting from the inside confines of my Jeep with the IS on, handheld, I certainly got more than a number of usable images.
Canon’s new EF 800mm f/5.6L IS USM lens with Image Stabilization is a much needed product for the working pro and serious amateur photographer. The lens handles beautifully; all digital captures were crisp with more than adequate contrast. In sum, it opens the doors to images I could only dream about years back.
