Strange question possibly, but along the way, have you bought an item of equipment that really made an impact on your photography (excluding the camera!)? If so what was it and what changes did it make to your photography? Seems to me that a lot of equipment is bought on a speculation that it will make a difference, it would be interesting to see just what kit has inspired what changes. My purchase? Not kit, but a photography course, the chance to take different pictures with different people that could offer advice/guidance/critique. What was yours? Ps. posting this in the Nikon forum, because I am interested in Nikon kit!
