We got back from my second trip to SA just a scant two weeks ago, and I'm slowly getting images cranked through the workflow; really need to get that Mac Pro, processing 5DII RAW files in DxO with a 2 year old MacBook gets old. Still fine tuning post processing on some shots, but here's a small selection of images. This was my first proper outing with the 100-400, and the first time I've really shot wildlife - last time I was there I only had a 4x zoom compact, which isn't quite the same as a 400mm lens...
I'll do this by order of animal size, starting with some Fruit Bats who were roosting under a roof at one of the base camps. The shot is a little motion blurred, high-ISO, but the moment was fleeting. This was one of the first shots taken of the critter.
Vulture in a tree. We couldn't see what the vultures were closing in on, as it was in a gully, but this one was cooly observing his buddies swooping in.
Baboon stuffing his face in a tree.
Running giraffes. They weren't running away from or towards anything, just running in circles, for fun. Shot a bit of video as well; it's very surreal, their lanky legs and necks make it look like they're moving in slow motion all the time. Slight cropping in addition to RAW conversion:
Two juvenile elephants eating by the roadside.
A big bull elephant walking down the road, spotted within about an hour of entering the park. Impressive view. Think I need to adjust lighting a little more to bring up the detail - my calibrated monitor shows the 'shadow side' fine, but web display not so much. Slight crop for framing, dust specks removed.
