I like to think that my favorite camera is my best camera. It just feels right! These days though, I'm approached at weddings by people who mention that their phone is superior to my camera, and depending on how we look at it, they may be right.
I took the above pictures a few days apart, one with my full frame DSLR, a Canon, with a decent lens, and the other with a Ricoh GR2, a fixed lens point-and-shoot - though with fully manual controls - an all around awesome camera. Which one is better? I shot RAW, ran them both through Lightroom, and slightly corrected them, and attempted to make them match, more or less. I wish I'd taken the same picture on my phone, just for comparison, though I don't have the phone with the latest/greatest camera.
So, if the Ricoh, which is vaguely palm sized and easy to carry, takes good pictures, why lug around a heavy camera? Why carry either if you always have a phone with you that takes good pictures? My reason is a combination between choices, and control.
With the DSLR I have easy access to all the tools I need to take the photos I want. It's easier than the Ricoh, control-wise. Lens-wise, the even better reason, I have more options and flexibility with the DSLR. Yes, it's heavy by comparison, but I can toss it in a bag, carry it on a strap, or tote it around in one of the many camera bags.
The Ricoh is a fixed-lens camera (with an option to adapt to another focal length), so that both reduces my options, and forces me to plan/see better. I think obstacles can force us to work harder, and better, so it's not all bad. I can have fully manual control, which I love, and like a lot of cameras, it has quite a few modes, so I can also shoot relying on the camera to switch around some variables for me. The best thing to me about the Ricoh, is that it's tiny and light, almost pocket sized. If I were larger, or had bigger pockets, it would probably be pocket sized.
So that brings us to the phone camera! I rarely shoot with mine other than to make notes-to-self, and remind me of photos I want to take. I only try to take a decent photo with it if it's the only camera I have, and a one-time opportunity. The technology is better and better, but there is very little ability to quickly change aperture, shutter speed, or iso (or the equivalents).
It's all about choices - too often I chose to carry only my phone, and my only excuse is that I don't regularly carry a purse, so I can't just toss a big heavy, or light small, camera into it. And excuses suck! But cameras don't. And which photo is taken with which camera? And at what settings?
