Finally I found this thread. I wanted to add some information to it.
I will disclose right up front that I am an insurance adjuster and have previously dealt with electronics losses.
Here are things that you need to know. First off, whether you rent or own, READ YOUR POLICY! You would be amazed how many people don't understand what is and is not covered.
Next, understand your Exclusions. Once you figure out what is covered read your exclusions to find out what is excluded. There many be exclusions depending on what country you go to. Exclusions for what caused the loss. Make sure if anything is EVER stolen that you file a police report no matter what country it is.
Next, and very important. Most policies exclude or limit coverage for property used for business purposes. That means if you get paid to use your camera, either professionally or just on side jobs they can and will limit or deny coverage all together.
If you are not concerned about the business aspect then I would recommend getting what is called an endorsement on your home or renters policy. Make sure it's an open perils endorsement and that the value you are endorsing it for is the replacement valve if possible.
Now some will say, "Well I sometimes get paid but the insurance company won't find out" let me tell something, we will find out. In this day and age it doesn't take much to find out. If you call in and say that you have a D3S, SB900, 24-70 & a 70-200 stolen you bet your ass they are going to investigate that stuff. I say this not to scare people, but to make sure you are covered properly.
Make sure that if you are doing it for fun and that's it to still get that endorsement on each piece of equipment too. Paying an extra few dollars a month is better than paying $3000 when you have to buy a new body.
Lastly, if you do shoot and sell photos, get yourself a business policy for your equipment too. Make sure to get liability insurance. Make sure there is somekind of loss of use in case your equipment is stolen. Make sure to read the perils on the policy and determine what is and is not covered on that policy also. Even if you only have say $5000 in equipment, it's better to be safe than sorry.
