The wife, @reina_reyes, and I went to Kyoto, Japan last October. Of course I brought my DSLR. However, when it came time to actually do street photography, I suddenly had an awkward feeling: every time I raise my camera to my face, the people who I want to photograph, the people who I want to capture in their natural state, will suddenly look at me and either of two things will happen - they smile at me or they turn around and walk away. Either way, I failed to capture the moment because the DSLR was very, very obvious.
And the sad thing was, I didn't bring my Canon G15.
But hope was to be found in the form of the iPhone 5s. I know that this phone has a great camera for a phone but, that time, I would be dependent solely on it.
What made the iPhone great was it's inconspicuous nature: everybody, well, almost, has a smartphone - I wasn't any different from most people - so, I was able to capture people as they were. And that was what I wanted!
And the phone, as to be expected, performed admirably. All I needed to vary my shots were my two olloclip lenses: the telephoto and the fish eye lenses. With these, I was able to get the shots that I wanted.
Panos were great, something that I could not do in-camera, with the G15...
And even in really low light, the iPhone 5s performed admirably!
Now, I am not saying that you should give up your point-and-shoot for a smartphone, far from it - I actually am interested in getting the new Canon G7x and its 1-inch sensor - but if you have absolutely no choice, then the iPhone is a really, really great alternative.
