You can't do AI Servo AF with an iphone either. I can go on and on about things you cannot do with an smartphone. The biggest thing for me is that I cannot shoot RAW and adjust WB afterward. I really have a strong dislike of working with JPEG.
So, even if you don't need these things, you should still use a DSLR? You can't put a DSLR in your pocket. You can't send a photo off to an agency to be published immediately when in the field with a DSLR.
As pointed out on another thread somewhere, most photojournalists use JPEG for speed purposes.
These specification arguments are pointless. Different tools for different jobs. No-one in their right mind would try to take serious bird in flight photos with a cell phone camera. No-one in their right mind would try to do documentary work with a 600mm lens. An iPhone is just another kind of camera. There are fixed lens cameras, medium format, rangefinder, micro 4/3, interchangeable lens, and any combination of these you like. Do they all have the same specs and abilities except the iPhone? Do they all do AI Servo AF? Do they all have super high ISO? You choose the tool that can do the job you need to get done.
I haven't seen anywhere anyone dismissing the qualities and abilities of DSLR cameras. I can't understand how anyone can be so dismissive of work because of the tool that was used to create it. Again, I have provided concrete evidence that cell iPhones are being used to produce quality work by photographers and that work is being reproduced in print media amongst others. I have pointed to individuals who are photographers, there is no other way to describe them. No-one has argued that iPhones are the best choice for sports, wildlife, multi flash studio work. In fact no-one has argued that iPhones are the best for anything, just that they can and are being used to produce work. Like it or not it is happening and the trend will probably increase. Will cell phones make it into the studio? Probably not for some time. There are various add on lenses and accessories and I'm sure it won't be too long before someone tries to do something more serious in fields other than photojournalism, documentary and street using an iPhone.
