I hear the D70 is a discontinued???(spell check) model now it is replaced by the D70s. But still a good camera.But to me for the money you spend on a D70 the extra that you get is not worth the extra you have to spend. Both cameras can do the same things but the D70 is a little easier they say to find your settings because it has a extra control dial, faster to change your settings is more like it. But I have not had a problem with the D50 yet as far as that goes. Know your camera and it's all easy. Try out as many as you can first then make your choice.
