If I upgraded my five lenses that I have to 2.8 I would probably have around $15,000 to $20,000 in glass. Right now I have about $2500 in glass. If I went out and spent $3000 on a camera with good ISO capabilities I would have a total of $5500 in all my CAMERAS AND LENSES. I have something I can use in low light situations for 10 to 15 thousand dollars of savings.

I do realize that the faster glass would be sharper but for me I can get pretty decent pictures at a price I can afford. If the funds were there to buy whatever I wanted I would have the fast glass and the higher ISO capabilities.

I am looking into buying a Nikon 70-200VR 2.8 lens from a friend at a price I can manage and I am looking forward to using it, Jeff

I would like to say that for me the thing that I consider really silly is not learning the equipment you have and getting the most out of it before buying a newer model and not learning how to get the most out of it either! Now to me "that is silly".
