I photographed this sandpiper on the central coast of Oregon mid-August. A small flock was flitting about so I decided to sit quietly in the sand and wait for them to flit in my direction, which they did. I rested the camera on my knees. Late afternoon light.
Canon 1D Mark IV, Canon 400 DO f4 IS + 1.4x, 1/1250, f8, exp. comp +1/3, ISO 400
Good low perspective Nancy, and I like the feeding pose too. For your set up, I feel the IQ is not quite there - is this a big crop. Another round of sharpening may help.
I'm hoping that a lack of sharpening is the answer, and I'd like to see the result after another round or two. The late-afternoon light is gorgeous; must have been nice sitting there in that soft light waiting for them.
Here is the image with another round of sharpening. This is only a 50% crop. Is this much different? Sometimes with the Canon 1.4 teleconverter on the 400 DO images seem a little soft. I have done the micro-adjustment procedure but I don't have a ton of confidence using the 1.4 (the new version).
I like the composition and sharpness much better on the repost, but it needs some CW rotation (which is OK on the OP). Nice feeding behaviour and I like the bit of water/mud being pulled up at the bill tip.
