There are no real rules. If you have enough megapixels you can use even small details to make a great image. Just beware of noise and distortions.
Nikon D3100 with Tokina 28-70mm f3.5, (I like to use a Vivitar .43x aux on the 28-70mm Tokina), Nikkor 10.5 mm fisheye, Quanteray 70-300mm f4.5, ProOptic 500 mm f6.3 mirror lens. http://donschaefferphoto.blogspot.com/
