Frequently, a poster will inquire about what camera to buy for filming. Often the price range is something to the south of $1000. The attached most recent film riot video shows what is obtainable with an I-Phone with a cinematic app. So, folks just starting out that own a current I-Phone can immediately create content with minimal investment in hardware.
I'm a bit different, since a have several towers, a lap top and old tired eyes that require reading glasses, my phone was <$100. I do all my computer related actions on, well my computer and I make phone calls and the occasional text on my phone. It's a good balance for me. The Current price of the I-phone 7 is $749. Something to consider.
