17 Protective cladding or other covering:
An endless variety of these can be found, so we asked nature shooter Tim Fitzharris what he uses: LensCoats. These waterproof neoprene sleeves protect against dings and nicks, and are available in a variety of camouflage patterns for shooting skittery critters.

18 Bubble level:
They’re a cheap, accurate, eminently portable solution to off-kilter horizons. Buy several. They’re easily lost—trust us.
19 Light modifiers for pop-up flash:
When we think of flash add-ons, we usually think of ones for shoe-mount flashes, but there are plenty of them for pop-ups, too. One of the neater ones is the Gary Fong Puffer, which can be mounted on most any pop-up flash via the hot shoe. It both diffuses and bounces the flash light, and folds flat for storage.

20 Eye-Fi cards:
Possibly the most elegant Wi-Fi camera connection there is, Eye-Fi is an SD memory card with a built-in transmitter that can automatically upload your pictures to a computer or social networking site, or directly to a smartphone or tablet.
