I finally have a charger for my camera so any excuse to take a high quality selfie and put that on the internet really. I definitely think that purchasing in a decent image capturing device is a great investment. I love love love it. It's so lovely to be able to think, 'Hey I could so take a nice photograph right now because of this lil' gadget' rather than miss a moment or deal with a low quality phone camera.'
What I'm using isn't the best by any means, but it works for me! In 2012 I bought a Canon 600d which has a flippy screeny thing and settings and wonderful things you need to take pictures of whatever you fancy. Probably the least techy way of describing anything, but you get the picture (ha ha).
Get a strap! If it doesn't come with one, you can get them fairly cheap on Amazon or eBay so there's no excuse. I feel like I need one because I drop everything, and I mean EVERYTHING. Sometimes I just forget to keep holding onto stuff. Not sure why, but there you go.
Make sure that if your lens gets all mucky with general dust or sticky fingers or whatever, use wipes catered for lenses. Generally regular tissues or towels (or the bottom of your t-shirt) leaves tiny fibres behind that, if anything, just make your situation worse. Again, these are pretty inexpensive.
Also, memory card. Duh, where else are you going to store your photographs? Exactly. I'm currently using a 16gb one which has more than enough space for me to take loads of pictures even when I forget to delete the old ones and move them to a file on my computer. Woops.
Finally, don't spend all your savings or money you simply don't have on a camera you're rarely going to use or won't ever know how to use. This probably goes for any gadget, but you know what I mean. You can get good DSLRs for a fair price what with all the new brands and such flying about it these days. Just check out reviews beforehand, maybe speak to someone instore who can help you make the best choice for you, and if you're buying online check out the retailer before throwing your money at them. You don't want to waste what could be hundreds of £££ (or $$$ or whatever).
P.S. I didn't work out until taking a picture of my camera that I couldn't use said camera, thus resorting back to my phone. The struggles are real, my friends.
