p.1 #1 · Yashica "medical lens"


Came across this on "the bay" -

http://www.ebay.com/itm/Contax-Yashica-Medical-100DX-lens-accessories-/170641392211?pt=Camera_Lenses&hash=item27bb050253

Now correct me if I'm wrong, but isn't this the lens from the dental eye camera? I thought that the lens was proprietary and not changeable / removable.

Of course it is removable, your looking at the fitted case and can see the mount on the back of the lens. I have one in the back room we never use that we got from a dentist friend of ours.

Well shiver me timbers. I could have sworn at one point I read it was a non-removable lens. Is is a proprietary mount that can't be adapted to anything else? Maybe that's what I read?

From the Yashica FAQ by Cees de Groot, the Medical Macro 100/4 ML (aka Dental Eye) comes in both forms: permanently attached to an SLR, and detached. I've seen both on eBay with some regularity. The same optical formula is available in a bellows-only version.

So what mount is it? C/Y ?

And the same formula is bellows only? So there's no infinity focus with this lens?

BTW, what's the power used for?

I'm curious about mount too, but don't know. Not sure about infinity focus, but this lens wasn't meant for that. So it wouldn't surprise me.

The power connection is for a built in ring flash at the end of the lens -

I just noticed that's a DX lens! Bollocks...that's another one I have to put on my "want" list.

I have one of such lens, it is great. The mount is standard C/Y I use the lens on my 5DMkII using a Big-Is adapter. Infinity focus cannot be allowed, in fact the repoduction scale is only between 1:1 and 1:15. On my lens the sync cable lacks, I will be thankful to whoever helps me to find one.
