Hi everyone,
A Happy New Year to one and all!
I just received another one of my favourite pieces of Yashica glass - the DX 100 f4 Medical lens - and it contained a surprise as it was new in the box and had been unopened since the 1980s.
It arrived in its original carry case along with a Contax 167MT, D-7 back, Yashica foot-pedal and doubler. I found the attached label inside the kit which I suspect may be the only time a Zeiss 50mm Planar was a free gift with the purchase of a Yashica DX (or ML) lens. I should imagine the uptake would have been pretty high - probably a good thing for Yashica's profitability in the USA that not many of the Medical Lens kits were sold! I've not been able to find a price for the DX100 kit as yet but I'll keep looking - it'll probably be found in a dental magazine of the period.
One continues to live and learn... |

After several hours of rummaging...
I am indebted to Popular Photography as back in 1989, in the classified ads Adorama listed this 100 DX Medical Kit at $1199.95. That was pretty fair as the 167MT was $539, the D-7 Data Back was $229.95, the DX 100 lens kit (no foot pedal) was $589 and the foot pedal was $47.
And just think, my ex-wife used to complain that there was no point in keeping those dusty old copies of photo magazines.... |

Nice find. I have a 55 dental, 100 dental and 100 medical. I have converted all for use on my Sony NEX (and the 100 D on my alpha)/ Will post images next week as I am jammed BUT here are some details you should know about these:
All are F4.
The 55 does NOT mount alla the c/y mount (found this out after I destroyed camera body).
The 100D lens can be dismounted by: Removing the bottom plate of the body, releasing the wiring harness, pulling the plug off of the mount release hole (side of mirror box as any C/Y camera) and pushing in on a lever within with small screwdriver.
All have a sliding aperture mated to the length of the focus (the aperture closes down as you focus in).
To convert any to variable aperture, you have to open up the body and remove the sliding pin and make a mechanism for the aperture.
Easier on the 55 and 100M as they have rear mount aperture controls within whereas the 100D has an electromagnet.
The electromagnet on the 100D is not variable. It is either on or off.
The aperture for the 100D has to be accessed from the front, under the flash.
The 55 is very sharp. The 100M is very sharp.
The 100M, 55 and 100D will NOT focus to infinity on a dslr or slt (dslr type) body due to their girth but the 100D can fit onto a dslr with mount conversion and almost make it... but not quite.
Either can be adapted to a mirrorless body, like my NEX but you cannot simply use a mount adapter as the lens will be too far out for infinity. I use portions of extension tubes.
Mounts are cheap, you can use the thin m42-nex and m42-alpha mounts (or whatever you have as a body. For the 100D on my alpha, I simply removed the C/Y mount and spacers and wedged in a metal alpha mount from an old maxxum lens (Minolta) as it fit snugly.
