Do It with a 50mm

You know where you are with a 50mm lens. It's a good reference point for anything else you might need, or think you might need. (Often you don't need anything else). If there is a poor 50mm lens, I have yet to hear of it. A few are overpriced but for the most part they are cheap, and excellent gatherers of light.
Photographed with an AF Nikkor 50mm f/1.4D lens on a Nikon D700 at 200 ISO. 3 seconds exposure at f/16. Cropped to remove an extraneous road atlas. I guess that the availability of sat nav and digital maps means that the once ubiquitous road atlas has pretty much gone the way of the Praktica camera. Anyway, I didn't want it competing for attention in this picture.
