When one thinks of a focal length ideal to nature or landscape photography 24mm usually tops the list. Historically use of a 24mm prime lens was seen as the ideal way to go and over the past decade lens technology has improved so much that wide zooms (14-24mm, 16-35mm, etc.) are now the norm.  The 50mm focal length on the other hand is seldom thought of as ideal for nature or landscape photography and more so for photojournalism or street photography. In fact it is for this reason that 50mm or most mid-range focal lengths were omitted from my earlier post Reader Question: What lens do you use for your Landscape photographs?

As of late I’ve been having fun with the 50mm focal length and I’ve been going out of my way to experiment with it. In the process I’ve rediscovered making use of much shallower depth of field in my images.  For nature and landscape photographers using wide lenses with deep depth of field (> f/16) is often the norm to keep as much of the scene in focus as possible. With a shallower depth of field (< f/2.0) a narrow plane of focus exists and bokeh becomes a more important visual component. Breaking out of my deep depth of field rut I’ve become increasingly fascinated with learning about the varying qualities of bokeh and it’s led me to purchase a rather rare lens, the Canon EF 50mm f/1.0L USM. I have to admit this particular lens has two qualities that piqued my interest: 1. The extreme bokeh created by the ultra-shallow depth of field it is subject to and 2. It’s ability to gather more light for faster shutter speeds in low light situations (ideal for night photography).

Below is an example night photo taken out of a plane window at 10PM. Visible to the naked eye was the wing and a hint of snow on the mountains. Much of city lights and stars were not visible to the naked eye. What impressed me in this situation is that a nearly pitch black scene could be taken handheld.
