Recently I have been ditching my automatic and zoom lenses and buying cheap prime film era manual lenses from E-bay. In my opinion automation has jacked up the cost of buying lenses and taken away much of the feel of taking pictures. I found a new joy in going out with my Vivitar fitted on my D40 to give me stop down imaging. I also just bought a manual 2x teleconverter for my Nikkor 135 f3.5. I am fortunate to have a Nikon D40 camera on which almost every Nikon mount lens fits.
