One of the must-have equipment for wildlife photography in general, and bird photography in particular, is to have a telephoto lens powerful enough to capture subjects with sufficient details and sharpness, without having to come too close to them. Since most of us can’t afford super telephoto lenses, also called second-mortgage lenses, some of us resort to using an extender, which is much less expensive, to increase the reach of our lenses. With a 1.4 extender, a 400 mm lens will be equivalent to a 560 mm lens.
I have had such an extender for two years, but almost never used it because the results had been disappointing especially in terms of sharpness. Finally, looking at photos posted by Jerry from Quiet Solo Pursuits here on WordPress, I decided to give it a try with the Canon 5D Mark IV that I have been using since last year.
Following are some of the shots I took yesterday at the refuge and at Colonial Lake under a bright sun with the 100-400 mm lens and a 1.4 extender.
