  1. Hi Chris,

    great show, but I got a add a little something. You talked a lot about prime lenses, but kind of missed part of the question that was asked. Why are there so many prime lenses (between 14-50mm)? I try to answer that, hope that might help your listener :o)

    First off there is a huge difference between the field of view of the lenses. A 14mm lens gives you a way wider field of view then a 16mm, as a 24mmm will give you compared to a 35mm. There isn’t much difference between 189mm and 200mm, but in the lower range you get way more on the image.
    Also there is a different look to an image done with a 24mm compared to a 35mm do to the perspective distortion of using a wide angle lens. While the 35mm makes things look rather normal you get more distortion (to exaggerate: a stretched look) with a 24mm lens.
    Also price is an issue when you look at the number of different primes. The wider the lens the harder it becomes to build it with a large Aperture. That’s why a 20mm 2.8 is about the same as a 28mm 1.8, but the 24mm 1.4 so much more then the 28mm 1.8/24mm 2.8, the 14mm 2.8 again so much more then the 24mm 1.4 (wideness vs. brightness).
    Depth of Field is another Point. A 24mm lens as a way bigger dof then a 85mm when using it with the some parameter (distance, aperture)

    When buying a prime you should first thing about what you want to use it for. When doing landscape or things where you want to capture a lot in the frame, something between 14-24 is probably the right thing. If you are using it as an all purpose walk around lens/journalistik style lens, something in the region of 35-50 might be right. For portraits, etc you might be better off with a 50-135. That’s a generell suggestion. You can do great landscape shots with a 85mm, also portraits with a 14mm got a special look.

    Hope that helped a bit.
