Thanks Kungpow for indepth explanation, and I think I understand it now.
Urk, I don't shoot much of anything except nature, mostly birds in flight or birds, butterflies, dragonflies, etc. I am not too worried about having a wide angle lens.
Now I have one more question. How many of you use just the viewfinder and not the LCD screen. I'm asking because the only digital I have is the one I mentioned, that Nikon and it only has the LCD screen.
I hope to be able to buy this by October, and I'm sort of tissed that I didn't have it a few days ago. I was out of film so I decided to go fishing instead. No camera with me and a small egret landed not five feet from me, didn't move for about 15 or 20 minutes. Long enough for me to get a few decent shots.
Then just a few minutes after that, a great blue heron flew up just behind me. I probably wouldn't have had time to get the heron but if I had that digital I could have a least tried.
