K-3 - A-400 and 1.7 AF TC
ISO 400, ƒ11, AV (1/200 and 1/320
You need a really bright day to use the A-400 (or any 5.6 lens, with the 1.7 TC. It's really made for 2.8 lenses. ) And also, just because you're technique is steady enough to use 400mm, doesn't mean it's steady enough for 700. Ye, I got a few images, of course the one that would have been perfect, the little guy ducked behind another bird, body perfectly in focus, but no head. At least I got a few for my efforts out in the cold. Even in bright sun, with lens that has a maximum aperture of 9.3, focus is really hit and miss. But even a blind squirrel finds a nut every now and then. (Of course smell is a big thing for finding nuts... but I digress.)
