These are, in my opinion, the things you should purchase right after the purchase of a DSLR (or even a compact camera):
- Joby GorillaPod Focus (review), and/or
- Benro Travel Angel A2691T (review)
- Extra memory card(s)
- Extra Battery(ies)
But another thing that you should very much consider, after purchasing some or all of these, is the organization of such stuff - you should not just throw things inside your bag because that would make things harder to find, especially when you're pressed for time. Also, you should not throw things in your bag carelessly because, though I think it's highly unlikely, the battery terminals may touch another piece of metal and that may short your battery out.
So, in order to better organize your batteries, consider the Think Tank Photo DSLR Battery Holder 2 - the "2" stands for the number of batteries that can be housed inside this very useful accessory.
The only thing you need to worry about this accessory is how to differentiate the unused battery to the discharged one. For me, if a battery is fully charged, then I let the brand name show. If a battery is used, then I let the terminals be front-and-center. So to speak...
If you haven't gotten a Holiday present for yourself, or if you are considering a gift for the photographer in your life, then this item would be a very useful but inexpensive gift. I'm sure s/he will love it.
(There is a version, also, that can house 4 extra batteries.)
So get yours here!
Note: As of this writing, the amazon.com photo for the "2" is whacked... I already sent amazon.com a message saying that the photo is wrong, so I hope that they rectify the situation right away. But don't worry, the link will take you to the correct item.
