I have an Adon telephoto lens which is some sort of device that can either be used as a telephoto addition to lenses up to 8", or as a stand-alone tele lens.
I had one of this years ago and used it as a stand-alone lens but this one seems slightly different. It came with instructions but they are, of course, missing pages 2 and 4 so the info on page 3 does not go with the chart on page 5...
If anyone has used one of these successfully, I'd love some tips. The 'instructions' are more confusing than helpful.
Thanks people (c'mon Steven Tribe, I KNOW you know this!)
