The Canon 5D Mark III is the most recent in the 5D range and would be a dream to own but it a little out of my price range.
The more affordable option would be to buy a body only as we already have 28mm and 50mm Canon lenses and you can always build on your collection later. The Canon EOS 7D would be ideal as the body is significantly less expensive than with the 18-35mm kit included. I've used the 7D for filming and stills and I absolutely loved using it. It takes the most beautiful photographs.
Another more affordable option is the Nikon D3200. Again, you could pay very little for the body only, depending on what lenses you already have, or invest in a kit with the 18-55mm VR lens and a Tamron 70-300mm lens so that you would have a lot of options.
If you wanted to invest in Nikon, another possible option that wouldn't break the bank would be the D7000 with 18-105mm VR Lens Kit. I would be a lot less familiar with Nikon, although I have used my friends Nikon for stills and I did find it was quite easy to adapt to it after working primarily with Panasonic and Canon cameras.
I think it's a case of once you know what you're doing with one camera, it's fairly easy to work with any make or model. I know a lot of people have their favourite brands but after using a few different cameras I'm certain I could adapt to any brand. Being as passionate as I am about photography it's about time I started to save for my own camera. I look forward to doing more research and finally choosing the one I want to invest in.
What camera do you use? Are you loyal to one brand?
