A feisty robin has been supervising my planting of our garden, knowing he’ll be rewarded with bugs and worms as soon as I get the hell out of his way:
His rounds take him to a perch atop the water station I’ve set up to make garden management easier. This allowed me to pre-focus and wait for a shot:
I’m still working the bugs out of my system for super-tele shots. These are at a focal length of 800mm (400mm from Gizmo, plus a Canon 2X Tele-Extender III.) The Extender negates the auto-focus on this particular lens and slows it to a maximum aperture of f/11, and the whole mess is huge, which contributes to vibrations from mirror flip-up.
At 800mm, any vibration is unacceptable, so I need to tweak this system. Perhaps a combination of live-view focusing, mirror lock-up and a cable release will yield better results.
