I'm still in Tanzania, just off the back of a great 5 days in Manyara, Ngorogoro and of course Serengeti National Park. Will post more extensive thoughts and more pictures when I get back home in a week and a half or so. Gear thoughts: - the E-M1 coupled to the 43 50-200 SWD and 1.4x teleconverter is a perfect safari combo. Fast focus, sharp, and compact for the speed and angle of view you get. - assigning mysets to the front two buttons (shutter priority with and without tracking AF) works great to adjust for action. - AF is very good, only very occasionally hunts. Not as good as the native options but still near as good as the canon 100-400 I had with a 5DII I took to South Africa. - with near zero chimping and brief review of the day's shots, I managed 468 shots per battery (2 OEM, 2 DSTEs). The OEMs lasted a little longer (490-ish) but the difference wasn't huge. - didn't use the 12-40 at all. Occasionally shot the 7-14, and most landscape stuff was handled with aplomb by the a7r and 55/1.8 or 35/2.8. If the upcoming Zeiss ultrawide is good that will replace the 35 and the 12-40 for traveling with wildlife, I think. And now the big 5. Well, big 4 and a rhino that's basically a dot. Ahem.
