What camera should I use?
When people like my photos they sometimes say: 'You must have a really good camera'.
Somehow people think that it's the camera that makes the image work. To most photography enthusiasts it's like asking Roger Federer what kind of tennis racket he uses, and attributing his succeses mostly to that particular racket. It's not the racket that makes him successful, it's he himself, knowing how to use it to the best advantage. He would still play good tennis match with a different racket.
Not that I'm saying it a different camera can't make any difference, I'm just saying it's the person using the camera that creates the picture.
Currently I am using using a Nikon 7000 with the kit zoomlens, I could, however shoot the same kind of images I shoot now with the ancient point and shoot camera I used to borrow from my mother.
Having said that, each newer camera's gives more and more control over things like Depth of Field, Aperture, Shutter Speed and so on. A (D)SLR camera's also lets you see through the lens and only deviate slightly from what you see and what the light sensor sees.
I really couldn't answer the question of the title without knowing more about the context you want to use the camera in, or the purpose. Architectural photography and landscape photography are two different worlds, although the biggest difference is in the lenses used. And then there is Macro and Portrait, Studio Portrait or Studio Product photography. And then I would still lack the technical knowledge to give a proper recommendation.
The one thing that is always true: the best camera, is the camera you have access to the moment you want to take the photo.
This photo was shot from inside a moving car and the kids enjoying the annual Thai festival of Song-Kran was also moving. I did have the big DSLR in the car at the the time, but it was tucked away in the camera bag. The only camera I had direct access to was the iPhone. So that's the one that was best for this situation. Had I tried to get the DSLR out the moment I tried to capture would have passed and I would not have gotten another chance to capture this moment like I did with the iPhone, the faces of the kids, the joy and excitement; I would have completely missed it.
A good photographer, which I aspire to become sometime in the future, can take good photos with almost any camera. As long as s/he knows how to operate it.
I have no idea what kind of filters I used on this image and unfortunately I can't seem to find the original. But I think this image does illustrate the point I wanted to make. Writing this post is also a nice reminder for myself to keep the DSLR ready to use, even during an otherwise rather boring long drive...
