Is Serendipity my middle name or what. I literally have so much photogrpahic stuff I cannot remember it all. Not a blessing, usually. But today it suddenly dawned on me that I had a Canon DP Adapter D10, and that it might fit my D7.
It works perfectly.
A DP-10 is a Macro lens convertor with an extension tube that supports a slide or negative copying holder with a built in diffuser. The lens is at the camera end and the tube connects to the holder on the other end. Whole device is six inches long with 58mm filter threads(male). Holds two slides that can be pushed through on a slide mech, or six negs on a holder that slides just behing the diffuser (and cc filter for negs built in). Excellent buiild quality and very good coated glass.
The magnification and optics are such that when it is screwed onto the D7 with a stepup ring it will focus a slide slightly over full size at 200mm on the D7 zoom. A complete slide at about 195, say. It will either spot focus on the slide or it can be done manually. The D7 lens functions straight tele, no macro setting required. Works like a charm.
An added bonus. The extension tube unsrews from the lens element, leaving one with a macro attachment that takes a 62mm filter, and will do my ugly thumb in perfect focus at about 4 inches filling the entire frame (zoom at 200mm). Guessing that it is 2-3x, at those settings. It does vignette at full wide, but can be zoomed through from 50-200.
From my previous use of it as a close up lens(and slide copier--its original design) on a canon 50mm, I know it is a good quality lens. It has very shallow DOF and will be used on a tripod.
I suspect that there are other lenses and copiers out there made for 35mm flim cameras that will fortuitously work excellently on the D7, as this one does. After all, its lens design begs us to try these things. I will try some of my good Componon -S enlarging lenses on it when I get a moment and add the results to this thread.
Hey, Bryan, need any more work, like putting together a list for your site of Convertors, macro lenses, etc, that are known to work with the D7.
If anyone finds something like that does a good or a bad job, how about posting it to this thread so there will be a record of our lens discoveries for everyone to see.
As to whether this one is available anywhere other than used photogrphic equipment places or camera shops that take trade-ins, I couldn't say. But, if you see one, grab it and do some slide copying and really close up work.
A WORD OF CAUTION, From my limited experience with both the B300 Oly tele and the DP-10 Macro (heavy glass) I have found that the zoom mechanism does not like the weight. If you have it pointed down , all the way out (200), the zoom mechanism will not lift it back up. I have found that I have to raise the lens up until gravity gives it an assist. I would be very careful with any add on. I do not think that it was designed with that use in mind. I support what ever I hang on the end with one hand on the lens and one on the camera to keep downward force on the zoom mechanism as little as possible.
Good hunting.
