I have a Nikon D80 and would like some help on what type of lens to purchase. We take lots of action shots (swimming and soccer) and would like a nice lens to get those closeups. I currently have a NIKON AF 70-300MM F4-5.6 G ZOOM LENS but would like to get something a little nicer. I was told by a professional photographer about a 70-200 lens that is a straight 200?? I didnt get the whole description but when I looked through it I was able to get closer than my 300. I do not know a lot about photography and the camera is more than I will ever need but I got it at a great price. I just want to get those closer action shots. I see that type of lens going for about $1500 which is more than I want to spend. Can anyone suggest a lens or a place to buy used equipment (other than ebay)? Secondly, I also do shooting inside at an indoor pool. My current shots come out too dark based on the lighting at the pool. Would a flash help that (or a better lens)? Thank you in advance for your help.
