A question if I may. How do you stick that small microscope lens to your main lens at the front? is there some sort of special adaptor/attachment or something?

I really like this setup, looks nice and compact.

P_T,
Here is a link with some information regarding the Olympus Telescopic Extension:

http://www.alanwood.net/photography/olympus/telescopic-auto-tube.html

Here is a link to a microscope objective adapter (there are 2 parts to this approach - there is more than one approach). First part is the adapter in the link and the second part is a T-mount to your particular camera.

Oh man... that extension is discontinued in 2003... but I can see where Canon got the idea for the MP-E.

So... Would I be able to use my MP-E as the substitute for that Telescopic Extension+ mounted macro lens and attach the microscope objective to it?

This is the part where I get a bit confused. So you screw the objective to the T-mount, now how do you attach that T-mount to your lens? I'm guessing it's that conical Minolta mount?

This is probably a bit much but I'll ask anyway, would any of you be able to dismantle your rig and show the components in their particular order?

Right now I'm still collecting more infos and perhaps later compile them all and make a thread which might be able to be stickied.

P_T,
The microscope objective is the only 'lens' used. In David's setup above he is using a Zeiss Luminar macro lens which has an RMS thread. The other elements are for extension, much like a bellows.

Don't stick anything on the front of the MP-E

Link to a picture of a Carl Zeiss Luminar:

The T-mount attaches to your camera or to an extension tube that is attached to your camera, then the objective or specialist macro lens is attached to the T-Mount via the RMS adapter.

The length of the Olympus Telescopic Extension can be increased or decreased like a zoom lens; but there is nothing inside it but air. They may have been discontinued; but they are still available on eBay. Why don't you consider a bellows in the meantime...they are not very expensive (but can be). I think I can find a spare EL-Nikkor 50/2.8 and a 10x Zeiss Jenna Microscope objective for you to use with it.....

So that whole 'stand thing' the camera is mounted on is the Leitz Aristophot is it?

Nice setup you've got there! Sounds like you could do with a few less adapters but I suppose it doesn't matter if they all fit together snugly!!

P_T if you want to increase the magnification on your MP-E, just add some more extension behind it..

There are two versions to the telescopic extension but they differ only in the magnification markings for the 38mm and 20mm bellows lenses being present (later version) or absent. These scales are indicated in green lettering and the presence of five such groups of markings shows the illustrated one to be the later version. The actual magnification values, in white, only become visible (uncovered) on the barrel as the unit becomes extended.

Unless you are using Olympus auto diaphragm lenses you might obtain almost as much versatility with a set of manual extension tubes (in this case Nikon) of mixed lengths.

Joseph,

Thanks for that. In fact I would be going to Olympus, not fitting Olympus to a different mount but the principle is the same. I have one adapter for M42 to Olympus OM which has such a lens at the back. ((This is the only such converter I have found on eBay, all others being T-mount adapters, which have a 42mm thread of a different pitch, such that infintiy focus is not acheivable).

Harold, you're welcome.

So, you've what have you got? Olympus tube and Olympus camera?

Normally, I mount RMS lenses like Luminars to the bellows or tube using a cone shaped (like the one in David's picture) RMS adapter. Instead of having one that goes from RMS to Minolta, I drew up one that went from RMS to T-mount, and had a local machine shot make me up a couple. That mounts to the bellows or tube with a common T-mount.

Unfortunately, the first two prototypes were prefect, but the shop just screwed up a up a short production run of a dozen of my RMS to T-mount adapters.

[rovebeetle]

When I am not using the stereoscopic microscope (Leica MZ16A)for photography I either use a 75mm EL-Nikkor or Leitz Photars with a RMS to M39 adapter which fits to the objective plate of my Novoflex bellows. The bellows is attached to a Kaiser micro-positioning plate and that again to a Kaiser repro stand. In the future I have to modify that setup, though, because it is not stable enough. The danger of introducing slight rotations when focussing is to high and to correct those is a headache.

Cheers
