I'm a prime lens user now but long ago I had a kit lens and a long zoom lens.
Those were my first two lenses and I used them constantly.
It wasn't until I was ready for my next lens that I realized I had no clue what I wanted. Did I want to get another zoom or what about those prime lenses? I heard some great things about prime lenses and their sharpness and low light capabilities, but until you use one its hard to make sense of it.
Over time I decided to just get a great lens for each focal length that was important to me.
I went back and and forth with zoom lenses to prime lenses finding many pro's for each.
Eventually I got into just prime lenses as they worked best for me. Having two cameras made the transition much easier as well. I would keep my primary lens on one and my secondary lens on the other.
For some of you starting out who may or may not have a camera yet its great to see the different perspective of different lenses. Different focal lengths have different strengths, feel to them and also can affect composition.
Lets take a look at three lenses that I use: The Nikon 24mm 2.8, The Nikon 50mm 1.8 and the Nikon 105mm 2.8
All of the photos below are at the same distance (6 ft) and at f 3.2.
My own personal style keeps me at 50mm and above as I like to get in close to the subject and try to fill the frame. Also, when you do use a longer lens it compresses the background and creates more separation which I also like.
