I've been feeling G.A.S. recently and considering a 5DIII along with superzoom for photographing rugby.
Not that it will make me a better photographer, but I'll be keeping up with the Jone's on the sidelines of the pitch.
Still a lot I can learn using my 7D and 70 - 200mm. I would feel some guilt if I chose this option.
I support my sons all I can and have on occasion gone over the top in sporting gear for son #1, and musical instruments for the second son. My second son, who played guitar in a jazz band 10 years ago, has rekindled his interest in playing guitar. I have found a beautiful instrument on the internet that costs about the same as a 5DIII and a superzoom. I almost sprung for it, but have decided to start him again in lessons, and reconsider the new guitar if he finds a jazz band to sit in with. I want to encourage him in his music, but don't want to spend my money too soon if this interest doesn't last.
My third choice involves aquiring a suitable car for close friend and his wife. He is in a wheelchair so suitable vehicles are few and far between as well as relatively expensive. Unfortunately the car they did have got totaled in an accident a month ago. They are unable to come up with the cost of another vehicle. My altruistic gene is telling me to give them the cash they need to replace the car totaled in the accident.
OH, the 5DIII and superzoom lens sounds nice.
