I have a love/hate relationship with the 20mm focal length. I came across my Nikkor 20mm f/2.8 at a school fair for a highly desirable price of $50. Considering these retail (still) for around $600 I couldn’t say no. Whenever I shoot with this lens it’s on purpose. I know exactly what I’m after and, more often than not, I’ll crop the top and bottom of each frame to give me a more cinematic look to the scene.
