We drove out to Kaw Lake near Ponca City today to get some more dust on a new SUV and get some experience shooting with a new lens. I advance of attending "The Great Smoky Mountain Photography Summit" I rented a Canon EF 100-400 f4.5-5.6L lens and a Canon Extender EF 1.4 III. I hadn't shot with this long a lens and extender before and though I would spend a couple of days before the trip to get used to using this with a monopod.
It certainly takes some getting used to, especially with a monopod. The image dances around in the viewfinder when trying to focus. I used AI Focus Auto Focus and a continuous shooting mode to try to maximize results. I will want to try AI Servo Autofocus as well to see if that gives me better results.
I knew I would need some practice with this rig to try to get any somewhat decent results. I might do better on the tripod with this combination for the stability but I thought the monopod would be more versatile trying to catch wildlife.
Anyway, here are the three best of the several hundred shots I took this afternoon. The combination of lens and extender provides an effective focal length of 560mm. Since I'm as quiet as Yogi Bear in the forest I still had to crop these images a whole lot!
