How to check for issues on a nikon d5100?

I'm going to visit Hong Kong soon, hut only for 2 days. Since everything is generally cheaper there I will be buying a nikon d5100. I'm worried that there might be some issues with it that I will only discover once I leave hong kong. What can I do to test everything that needs testing while at the shop AND when I get back to the hotel? PS. When I say everything I mean EVERYTHING like sound ISO and the whole thing. (I'm a beginner:$) thanks in advance!

Added (1). When I say issues I mean "errors" or "faults" that would require me to go back to the shop and exchange it for another nikon d5100

The D5100 has NO "issues"

You however will have an issue if you need to use Nikon's warranty service. USA warranty covers Nikon's purchased from an authorized dealer of Nikon USA In Europe, a Nikon purchased there likewise has to be repaired there.

What you will be getting is an International warranty and if the camera does need warranty service, you will have to ship it to an International service center. That means international shipping and sometimes customs.

I would sit down with the manual and go through each feature. That should give you piece of mind that the D5100 you have has no faults.

You can download the D5100 manual in advance from here: http://www.nikonusa.com/...100_EN.pdf

If you are buying from Hong Kong you might not get the UK manual included, so it would be worth taking that with you.

All you can really do is take a range of shots, with and without flash and take some video footage and play it back. Just use it for a day and evening around Hong Kong to take a range of pictures and see how they come out. It only takes an hour or two to charge the battery so that's the first thing you will want to do when you get it.

Get a good SD card in advance and test that before you go so you know there are no issues with the SD card. I would recommend this one - they work great on my D7100 and my wife's D5100:

Also think about getting a cheap case for it that you can sling round your neck. If customs see you bringing in a boxed D5100 they might want to charge you import duties for it but if it's in a camera case they are more likely to think you already had it.

The D5100 eats battery relatively quickly, so getting a spare is a good idea. One can be charging while you use the other, so you can have at least one fresh one ready every day.

Also, check that the charger isn't restricted to Hong Kong plug sockets and check that you can set the menu language to English. If they try to give you demo stock they may have already set the language, so it's worth checking you've got a brand new one.
