Check out our latest episode on why we think filmmakers should strongly consider upgrading to the latest iPhone (the 8 Plus is what we did, but the X would be good too of course).
We know they're expensive, but the new tech really is impressive and filmmaker friendly - and we think worth it.
One quick note... The footage we shot was pretty tough for lots of cameras, let alone a smartphone. Lots of motion and detail in the footage (traffic, blowing reeds, etc.) and so keep that in mind while watching and assessing artifacts, etc.
