The Best Rain/Snow Cover***

There are many options available, but for all day protection and features that allow you to fully operate the camera, Hydrophobia is the cover to have. ***Buyer beware, these covers are designed for DLSRs and specific Sony mirrorless cameras. Take a minute to get the correct eyepiece for your system. With the correct eyepiece these covers are fantastic. Like many, I recently transitioned to mirrorless (Canon) so I'll have to use my Think Tank Emergency Rain covers for the time being. I'm keeping a DSLR (or two) and my Hydrophobia covers will see continued service (there may even be an Exacto knife and some gaffer tape in my future to make these covers work with my new cameras.)

Great rain cover

Was in need of a new rain cover and asked around and every photographer said to go with the ThinkTank cover. I have been very happy with it and has kept my camera and long glass dry.

Only works for Canon

Because of the need to use an eyepiece to make this work, and that eyepiece will only work on a Canon, everyone else is out if luck. Shortsighted and unfortunate on think tank's part.

Hi Dan, We sell multiple eyepieces for various brands - Cheers, Simon

Mirrorless camera issue.

I have these fo my DSLR cameras but since the eyepiece on my mirrorless is not removable this product won’t work. Will Thinktank be addressing that issue in a newer version?

Hi Jamie, we make a range called "Emergency Rain Cover" they don't use a dedicated eye piece, maybe check them out.

Best rain/snow/sand protector ever

This was a replacement Hydrophobia. After years of use in rain on 5 continents, snow on 4 continents and desert sands on 2 continents my old one finally wore out. The product seals up my camera/lens beautifully while allowing me full access to my controls. I couldn't recommend this product more highly.
