Photographer and writer Shawn M. Tomlinson, author of the Photo Curmudgeon column and books, explains in detail the joys of working with a professional, albeit older, DSLR, the Nikon D1. "In fact, you can put your hands on a professional DSLR body and a lens for around $200 if you really want to know what all the fuss is about," Tomlinson writes. "No, I'm not talking about a Nikon D4S that, ah, 'fell off a truck.' I'm talking about the very first, ground-up DSLR for the professional market. The Nikon D1." The author covers buying and working with the Nikon D1, illustrating points with many D1 photos. In the second part, Tomlinson explains the usefulness of prime lenses. He considers the uses, advantages and disadvantages, and provides a conversational approach to making the move to primes. "In this short guide, I give you some pointers about what prime lenses do, what type you may need for your particular photographic vision and how to choose what you need," Tomlinson writes.
