... the one you have with you. That's ridiculous.
It's like saying the best woman is the one sitting next to you on the bus. Really? What would your wife think about that?
I mean, yes, I get the point of the cliche; I just don't agree with it. When a photo opp presents itself, I will capture it with what's available at the moment: my iPhone, OM-D, X-20, whatever I can get my hands on. And hopefully I'll get a good shot. But that's triage.
The best camera is the one that I've bonded with. It's the tool that I don't even think about operating. We've become one. I can solely concentrate on the subject before me without having to leave the creative side of my brain.
There's something to be said for really learning how to use your favorite device, regardless of what it is. If you're an iPhone shooter, then find an app that feels natural for image capture. Learn every aspect of it. Know that software and your smartphone inside and out.
In my case, it's the OM-D. I have a default mode for my settings, so all I have to do is turn it on and take the picture. No fussing. Just photos. If I need a bit more reach, I press the Fn2 button next to the shutter to double the magnification. If I need exposure compensation, I rotate the knurled collar next to it to lighten or darken the image. I don't have to pull away from the viewfinder to do this. It just happens. I'm in the moment.
The best things in life are those we invest in. I put energy into learning my craft. I know my camera, the software I rely on to process the images, and the audience to whom I present the final product. I know this sounds odd, but I even have a feeling for who you are and what matters in your life.
I'm not settling for the woman on the bus. I'll wait a bit longer to see my family. I know who they are. I like them. And they make me better.
