Unfortunately such topics often lead to some less desirable niggling and arguing. So I apologize for this posting, and precede it with the note that it is meant as purely factual, not in any way brand-related, although of course it is about brands. But I'll leave the brands out of the posting, to avoid arguments about brands. With this posting I want to say that getting the right gear can be important, even for hobby photographers.
I had a DSLR, a simple model, but still a step forward from Compacts. But I was disappointed by the image quality. Sometimes the colors were not realistic, sometimes details disappeared, the metering seemed to always favour the wrong portions of the image, dark spots were too dark, bright spots lacked detail and had the wrong color, once a friend explained to me that the metering was off because there was a sand road in the picture which reflected the sun and threw the metering off - I had not even seen that in the seeker, because the viewfinder didn't display 100% of the image.
Then I started researching and learnt - also with the help of a friend - a lot about digital photography, and also a few things I had forgotten since my analog SLR days. And then I went out and researched for cameras offering more dynamics, offering greater bit depth, offering the technical aspects which would allow me to recover detail from blown highlights and darker spots, whose viewfinder would show me 100% of the image, and so on.
In the end I found that camera, and bought it, and I am very happy I bought that camera and not another one (ok, I bought another one, but the same family, that's another story) because it has the ability to give me good pictures to work with, good pictures taken under the light conditions I like to take pictures in. With a camera which does not have these abilities, those images might still look nice, but colors might not be all there, details might be lost, and the colors might long wrong here and there. But with the camera I have now, all this is not the case.
So, while I don't want to talk about a brand, I would like to say that even for hobbyists like myself, it can be an important decision which camera to buy. And of course, which lens. It is true, usually it is the photographer who causes the problems, but then again, sometimes it's the camera, and getting the right camera for the purpose can make a difference. For a hobbyist, it's only for the fun, and hence maybe not that crucial. But it's still nice if the camera gives you the best possible result.
