I know what you mean. After visiting Luca in Jackson Hole, we met a photographer that was shooting with a 600mm Canon prime lens.
Cindy took one look through the lens and talked about it for days afterwards. On our drive bck to Michigan, she said to me "If there is one thing we buy this summer, it is going to be one of those lenses!"
I about crapped my pants when I heard her say that. She said "I dont care what you ahve to do, but make enough money this summer to buy one of those lenses before we leave to go back out west next winter."
I joked with Luca saying that I should have introduced her to some pros years ago and let her fool around with their gear.
Now I just need to figure out how to make money...LOL
