Is the a6000 miles better than the a5000? Hi all! I'm looking to upgrade my camera from a fairly basic point and shoot to the a5000 or a6000 or something similar. I am starting a business and would be looking to take photos of the backpacks I make on their own, with people modelling them, and videos of the sewing process.

Would the a5000 be adequate? I can find it second hand for about £200, while the a6000 is at least £300-400 even on ebay. 

I'd mainly be shooting for Instagram. Thanks!
