I think you are making the right decision here. As a commercial photographer with a bit over a year's experience using the I1P with X5 I'm planning to upgrade to
I2 with X5S shortly. The I1P/X5 was a wonderful step up from P3P in terms of still image quality and lens flexibility, and can definitely be used to produce commercial quality stills. But the I1 has always felt just a bit clunky to me in the air, and it does not hold position while hovering as well as my Mavic or my friend's
I2. Having flown his
I2 a bit I am convinced that it is a much better platform for photography as well as videography. I can't imagine someone buying a new I1 these days vs the
I2. As a prior poster said, if you get the bare bones
I2, X5S without lens, and then some Olympus lenses, you can get started with a very decent
I2-based still photography platform for not that much more than a new I1P with X5. And then when you get seduced by the sheer wonder of shooting high quality video, you can buy all the upgrades that make the
I2/X5S such a killer video rig too! ;-)
