I am a beginner at all of this. I have had this camera for about 5 yrs but I am still a beginner because I do not use it every month. Mainly for sports with my kiddos and for vacations.
I was at a basketball tournament this weekend and the pics suck! HAHA I did put it in manual mode and adjusted it to freeze the movement of the kids but it was dark. I personally don't want to spend $2500 because I am not using it to make money. There is a lens that I found and it said it was great for indoor sports. It's the Nikon AF-S DX 55-300 F/4.5-5.6G ED VR. I do want a 200 or more zoom as well. I am willing to spend around $600 or so. Hope someone can guide me in the right direction. I have taken some great pics with this thing and love using it.
