the #1 mistake anyone can make is thinking better gear produces better images...
improve the photographer...cheaper and more effective.
i dont dare to calculate what i have spent lol... started out from a nikon d90 .. and the upgrades went out of control.
It is a good point to always buy whatever u can best afford though.. that will show you how much your skills are lacking.. and u can improve from there.. concentrate on skills and ignore about the gear already haha, at least for a while.
