I love the D80 & I am pleased that I chose this camera in the past over less-featured & plastiky models from other brands. However,I feel limited by it,in the present. I can't shoot ISOs over 400,the focus is not amazing,like the higher end cameras have (& that I really need) & of course,I need a bigger camera,with a grip(complete with focus joystick),for better ergonomy purposes.
I am heading in the professional direction with my editing/retouching & I feel the need of a better camera & a better all-around lens. Soon,I think I'll buy the 35mm F/1.8,because of it's brilliant optical performances. The list continues with a better camera.
