and educational. I use 105 AI-s F/4,2.8 and AI 2.5 lens. I like the AI the most. I do not do the stop down metering with the D700. The camera does that for me. I use the appropriate aperture and then let the camera give me the shutter speed. Then again, I am not in to street photography so, I have all the time especially when I use AIS 300,400 and 600 lens for my backyard photography. I do love the out of focus rendering from these lens and the color is fabulous when I shoot with D2X.
Some old lens will never go out of usage, like the Takumars , Rokkors or OMD lens.
Thank you Casey.
