I have been endeavoring to reduce my gear input for several years now and for the most part I have been pretty successful. I went from full mirrorless camera systems to one rangefinder and one lens combination and for a while that was a perfect set up. While it is great to have a bunch of lenses and interchangeable bodies the age old problem of what do I take and how do I carry it always drove me crazy.
And now after several years of playing with iPhone cameras I took the leap and made the decision to jump into the world of mobile photography feet first. I have become so overjoyed with the quality of the images and the apps and controls that allow me to capture the images I want with virtually no fuss, no weight, and no having to decide what I am going to roam the streets and country side with. It is just my iPhone and a couple of add on lenses (which I rarely use) and I am off to a wonderful creative day.
I do know that at this time a mobile device cannot quite take the place of larger sensor mirrorless or Dslr equipment but non pro and pro photographers more and more are embracing the benefits of having a system in their pocket. I know I do and I have been in this business a very long time and I have evolved into accepting the fact that my iPhone can pretty much do everything I need to do from studio to street photography. I am a convert.
