I started using a kit lens 18-70 nikkor, shifted recently to a 35mm f2, so far it has not left my camera D70s. I find my pictures have improved significantly. I am looking to add to my kit for something with more range, probably either 50mm 1.4 or 85mm 1.8? Any opinions on which len? If you have both which gets more camera time? I occasionaly shoot runway fashion shows for work around a dozen times a year, or booth pictures at trade shows around 24 shows a year (I have not had a chance to use my prime in this situation yet) and the rest of the time use it to take pictures of my kid. I want similiar or better glass to my 35mm f2. I do not want to lug around any huge or heavy lens, not my idea of fun. Basically looking for a two lens kit right now, light weight, compact that will let me have more range. I am just not sure how much more. What do you find gets more time on your camera? How are these lens at locking on to moving targets (models walking) in low light?
