I love a rucksack: I genuinely carry more than I need because I hate being somewhere and thinking I’d really like to use my such-and-such lens and I haven't got it with me. So a really good camera rucksack is a must.
A polarizer: Kase magnetic filters and polarisers are absolute game changers. They make it so fast to pop them on and take them off. I can't be faffing, screwing things in, putting extension holders and filter holders on my camera. But with Kase magnetic filters and polarisers, you just slap them on – job done. I’m very impressed with these, so they’re definitely in my essential kit.
Lens cloths: Lots and lots of lens cloths!
Waterproof covers: I carry really cheap flimsy waterproof covers with me that pack down really small. If I'm somewhere where it is raining, but don't want to miss the shot I will throw one on to protect my equipment. I then don't have to make the decision of either missing the shot or ruining my equipment, I can do both.
Hoodman Launch Pad for Drone: I really like using my drone to capture the farm and animals in a wider context of their environment. I use a Hoodman Launch Pad, which is absolutely essential to keep my drone clean, dry and safe. It protects my car when I launch off its roof and also saves me chopping down many grass blades with the propellers when launching on grass. The Hoodman pad has really helped me not have to replace my drone propellers too often.
