I can not say enough that, to me, equipment does not matter. Sometimes I do get a question with what brand I photograph… It doesn't matter, it is not the camera which makes the picture, it is the photographer!
This said, lenses are important for the image, as well as flashlight. Recently I was photographing in a 'konoba' which was very dark. Well, I can assure you that I was very happy with my three portable flashes and one assistant to carry this all.

But to come back to the camera question, which brand do I use? I use several brands, several kind of cameras, both digital as film, and depending on the atmosphere, the light, the mood I pick a camera and make the images I want… like a painter takes his pencil…
And all what counts in the end, is the image…
