Pros: Works well
Cons: A very tight fit

What I have is the Pentax Microscope Adapter II, which is basically the same adapter but has an M42 screw mount. I got it boxed in a car boot sale (swap meet) for 4, about $5.22 at current rates.

It's nicely made, but a very tight fit on my microscope, which has a 25.3mm diameter lens tube. There are three pieces to the kit I got - the clamp and camera adapter, and a metal tube that fits inside the clamp with diameter 22.7mm externally, 21.1mm internally, length 42mm with a flange to fit the mouth of the clamp part. The instructions I've found on line say that this is a "light-sealing tube" used instead of an eyepiece when the adapter is used with a microscope objective but no eyepiece. I've never used a microscope adapter that way but it presumably gives unusually low magnification.

There's a slot in the foam for a circular object which was probably an artificial to daylight filter.

Since these are basically connectors, not optical components, their performance can only be assessed in terms of how well they fit etc. In this case there were no problems apart from the slightly tight fit around the microscope tube, which also occurred with my previous adapter. Since I'll mostly be using it with a Nikon camera I'll have to add an M42 to Nikon adapter, one of the cheap ones without a corrective lens. The photos show the components and a picture I've taken with it, from a Victorian slide of whale bone, using a Canon body since I already have an M42 adapter for that.

Pros: Very easy to use, does a decent job
Cons: Non, at least not for me

Wanted one of these for a long time, so I could make photos of microscopic botanical objects. Used it a few times now, and I must say that it is very easy to use. As said before: the silver part joins the microscope, the black part the camera, and then they're joint together. Don't forget to use the microscopes eye-lens (oculair)!

Here a photo made with this adapter. It's a leaf cross section of fine sheep fescue, a grass. Magnification 7x9.

Pros: Nicely constructed , easy to use !
Cons: None

Wanted to experiment with taking some photo's through my microscope . Wanted to lock camera and microscope together !

This does the job very nicely . The silver part of the adapter attaches to the microscope , and the black part to the camera's lens mount.

When the camera is joined to the microscope is by an elegant bayonet mount with locking ring.
Line op the 3 red dots , the a twist of the ring labelled ' Lock ' is all that's required

The manual is also very instructive on the use of the item - I've scanned the manual and converted to PDF - just need to find where to upload it to ( If that's allowed )

Attached to an old Brunel SP2 the assembly is very stable using a K-r !

Just need to practice my micro-photographic technique now ! If I get something interesting I'll post pic's !
