I've been using Imaging Insurance for years for all my photo/video gear, plus the phones, computers and other stuff I might travel with. Reasonably priced, very flexible policies to meet your usage needs, e.g. I only travel with a subset of my gear so I get a discount for that. Best of all, no quibbles over any of the claims I've made so far, including a complete loss of a lens into the River Arno and a Canon 1DX drenched by salt water in Iceland.
Would be worth checking with your home insurance first though; they'll often add specifically named items like photogear to your existing policy for a very negligable fee. You do need to carefully check what they cover and exclusions though, especially if you take your equipment overseas.
