Choosing the correct tool for a job or project is important. For the we35 research project I have chosen the Nikon 35mm f2d. Cheaply bought on eBay , a small size and easy to keep with me at all time this lens was just right. While not considered the best 35mm by many , with newer versions available by Nikon and Sigma , it is the best for me. To give it a thorough first test I took it out to lunch , a nice controlled environment and I was hungry.
