OK I have been away for a while due to a lot of work and other obligations I won't bore you with. Anyway, this is an image of Bat Eared Fox on a termite mound turned into a den from our Tanzania trip this past winter. It was about 1/4 mile from camp.
1D4 with 500 and 1.4 TC on bean bag from Land Rover. Evaluative metering at ISO 1600 and f 11 (to get the nose and ears and both animals in focus) and 1/400 sec. EV + 2/3. Cropped to about 80% of original.
You were very lucky to get such a good sighting, we have spent almost a year on Safari in Africa and have had only 4-5 sightings and very rarely in good positions or light.
These are one the "cutest" animals in Africa, and you have got a great image, and made the most of your luck.
