I make videos on YouTube and need a professional quality camera for 3 different kinds of filming:
1. Filming interactions from far away (30-50 ft). I need about 4 hrs of battery life for this.
2. Interviews from medium range (5-10 ft). I also need about 3-4 hours of continuous filming for this one.
3. Vlogs from close range (3-6 ft). I would like this to have an effect where the background is blurred and the picture is focused only on the person talking.
Since I have such a wide variety of uses for it, I was thinking of getting a DSLR but the battery life on those are not too long so I'd have to buy multiple batteries. Each battery only lasts about 30 minutes so even with a a battery extender (where you can put in 2 batteries at a time), I'd have to end up buying 8 batteries and keep switching them out.
Another option would be to get a camcorder with an interchangeable lens (like the Sony NEX VG20) but these have worse reviews.
Any other suggestions you guys can help me with? Thanks in advance.
