Then I discovered this camera
I would not change and come back to my previous camera, even if it can be considered as very good (Nikon D700). So light, such good quality and so simple. I walk in a street or anywhere, i do not feel the camera's weight, and it's always ready for a picture.
With some very good lenses, you can take sharp and impressing pictures. But I know that photography is firstly a question of personnal feeling and impression. Therefore, my opinion might not be yours !
