For example, impressive scenes can look very unimpressive with ultra-wide shots. If you look at the "15 controls my mind" thread, you will see some brilliant composition, often involving interesting foreground elements with some relationship to the background. Many people also take advantage of the superb flare-resistance by using the sun or other bright light source in the frame. The microcontrast with the 15, particularly in the centre, is really awesome - which means you can get great detail with the foreground subject. The MFD is really short too, so you can get interesting perspectives by getting very close to the subject.
I found myself in the doldrums last year shooting with zooms. After getting the 21 and 40 limiteds I haven’t used my zooms since October!!! I discovered that I had too many choices with the zooms and honestly couldn’t figure out what to photograph! After using primes, I have found that I try to envision, compose, and frame according to the lens. I am sure I will use my zooms when I go hiking and for travel, but I have found a whole new world using primes!!
I have subscribed to the 15mm controls my mind thread and have been very impressed and can see what you mean about framing with UWA lenses! One thing I was glad to see was that starbursts ARE possible with the HD version! I was a bit worried about that, but I think it will be okay!!
