So I'm not a professional photographer by any means. Any photos I take or make money off of are more like a side business for me. I've gone from using a 7d which I sold to using a 5d mark ii the last few months. I went and purchased the 5d mark iii today presale. I sold a few lenses I never used or that were for APS-C sensors so I can't use them anymore. When I was doing that, the guy at my local camera shop who is awesome asked why I wasn't selling my 5d mark ii. That made me think... I had kind of just thought I would keep it as a "back up" camera but I don't know how often I'll end up using it once I get my 5d mark iii.
I know a lot of people have more than one because of the type of photography that they do ie weddings, etc. I am doing more portrait photography these days as well as outdoors photography and I am torn now on whether I should keep it as a secondary or backup or sell it. I don't NEED the extra money because I was super lucky and sold some great shots recently that helped me fund my 5d mark iii but at the same time, having extra money in the bank doesn't hurt.
I wanted to know your opinions on having more than one DSLR and for those of you who have more than one, do you use the other camera often and what for. I just need help trying to figure out if I should keep it or if I should sell it. hmm
If you are selling your work or working for pay at all, by definition you are acting as a professional photographer. So just accept that and move on.
Part of being a professional is being dependable and never failing to deliver for your clients and customers. Often that means having more than one camera, in case anything ever goes wrong with the main one you shoot with.
There are also times when it's handy to have multiple cameras set up for use, to be able to quickly switch back and forth between the lenses you have mounted on them. I use a pair of 7Ds for sports/action photography. Usually they are set up with 70-200 and 300mm lenses or with 24-70 and 70-200. I also use a 5DII for other types of photography. And I have several older cameras as backups for myself or others who are helping me with larger jobs.
