It's been ages since I had time to write an article so I think I'll break back in with something not-to-technical.
Photographing the little things in the SANParks is a unique challenge, mainly due to being vehicle bound. Getting up close and personal can be next to impossible, and often a telephoto is needed for that "macro" shot rather than a 1:1 macro lens (in which case it isn't really a true macro
This is one of the few times when it also pays for the photographer to be the vehicle driver. There's nothing more frustrating for an innocent non-photog driver than having the passenger behaving like a back seat driver. Trying to get the car into the perfect position to photograph a dung beetle before it scuttles off into the grass when you can't actually see it is near impossible. Not to mention the high fatality risk for the dung beetle.
Back to the lenses for another rule turned on it's head. I have a pretty horrible Sigma 70-300mm lens, which doubles up as a "macro" lens from 200mm-300mm. Horrible it may be, but it's perfect in such situations. Imagine a hot sand road in KNP with loads of little butterflies flitting about it, mercilessly teasing the carbound photographer. Instead of breaking the rules (tempting as this may be) and ending up in a lions belly, the telephoto lens allows you to rest your camera on a support on the window sill and capture the tricksy little lepidoptera's image before it realises what has happened.
Good support is essential for these types of shots - and I don't mean from other humans sharing your vehicle, although that is helpful too. Some people swear by beanbags, others by window tripods. I've not tried one of the beanbags with a tripod screw yet, but do find that homemade ones are very effective. If you are on a tight budget and don't have any of these luxuries, grabbing a pillow from your tent before heading out in the morning can save you much heartache and nab you a crisp shot of a tortoise eye just before it retreats back into it's shell.
