iPhone vs DSLR

I was standing on the shoreline this evening looking out at the Gulf of Finland and there was this rather nice old boat sailing by.

I took a picture with the iPhone (above) and then with a Canon 550 DSLR with 300 mm lens (below) to see what how they compared to help Tillerman with his question.

While the DSLR might be heavier there is a good reason why I lug it around.
