Here's a product photo taken with the iPhone 6-plus that I worked on a bit. Sitting it on top of my car roof (which was fairly dirty), I had to clean up many spots plus a few unwanted reflections. The exposure is typical iPhone6 - f2.2, 1/1000, ISO 32. I've found the iPhone 6p good for individual portraits and product shots like these, where the subject occupies the larger part of the frame. This particular headphone is generally a special order item and sells for $1700 USD.
