Meep, meep!! Wile E. Coyote was nowhere in sight when the Roadrunner made a quick visit to our blind in South Texas. Greater Roadrunners are native to the Southwest and we were delighted to see this one run quickly past our lenses, pause to take a quick drink from the pond, then just as quickly disappear into the scrub. It was a great finish to a great morning of shooting near the Rio Grande. At Moose’s suggestion, I had switched from my Nikon D6 to my Nikon Z6II mirrorless camera, still using my Nikkor 500mmPF lens. There was a recent firmware upgrade to both cameras that made significant improvements to their autofocusing systems and I wanted to compare the two. I was, quite frankly, astonished at how quickly the Z6II acquired focus even with the 1.4 teleconverter attached. In previous versions, some auto focus functionality was lost when a teleconverter was attached and the upgrade has returned that capability. It acquired focus almost instantaneously and kept focus. What an improvement to an already spectacular focusing system!
