I am glad to given a chance to have a unit CANON EOS R3 to have a series of test on Birds/Nature Photography.

As for other camera, I plan to have series of tests which related to Tropical forest birds Photographer concerns eg. ISO performance, AF performance, Raw files dynamics range etc.

After days of basic understanding the camera (actually it is like a upgraded version of my old CANON EOS 1dxm2). I will try share other view of the camera later in other posts, here lets share one of the major concern : AF performance.

For this test, I am using

CANON EOS R3

CANON EF 500mm F4 IS2

CANON 1.4x TC III

No feeding, No nesting and no idea what bird flying to/from which directions. Just base on what you see and trying the Camera capability to focus and capture.
