Don't worry, John. There are always people who have camera gear worth many £1000's, and if they wish to spend their money that way, it's their choice. Personally, I am not in that league. The challenge is to get the best you can from the camera you actually have. I sometimes dream of using those fantastic professional lenses, but I am content trying to get the best I can out of the second-hand lenses I have acquired over the years.
