how do I set aperture with cheap extension tubes on the nikon d3100?
Is there a way to set aperture on the nikon d3100 when using cheap extension tubes? I have read that you can set aperture by holding down the depth of field preview button while attaching the extension tube, However the Nikon d3100 does not have a depth of field preview button. Is there any other way to set aperture with cheap extension tubes?
by the way, I don't have manual aperture adjustment on my lens.
My guess is no.
The only extension tubes that work with dSLR's and newer AF-S lenses have to be those specifically designed to connect the controls from the camera to the lens. These extension tubes will have electrical contacts on them
Going cheap has limited value in this new age of dSLR cameras
