I'd be keen to hear recommendations for raincovers for the AC160. I have tried the Petrol raincover and found it to be way too fiddly. I already have a Kata CRC14, from my old HMC151, which I find a tad too tight to operate the focus ring on the AC160. Portabrace appear to have a specific slicker for the AC160 but it's pretty damn pricey - am I missing any others?
