What I like about the Df (well one of many things I like) is that if you see something that looks like it may make a good photograph, the Df will help you take the photo that your mind sees. I was walking home this evening, the light fading and a calmness telling me that night was nearing. I saw the first tints of red and so set my Df up with the 300mm f/4.5. The photo, whilst not exciting, was pleasing to take and a moment in time that is now passed as it is now pitch black. The more I use my Df, the more I like it.
