Cost very low for high quality ....
you can use 2 raynox dcr 150 one for lens tube, one for lens adaptation for micro 4/3 (best captor/sensor for this system).
Adpatation give 2 quality = no loss of picture, good optical precision (dm/de reduced, dw/de very small (good optical precision).
- Use a manfrotto plate for each round trip (40 picture with 1/4 mm precison each) = 10 mm for delta E.
- Make a return of object to find the same position you have leaved
with a z plate (50 um precision).
give up bellows and jump in my world
.
No limit, no motorisation.
Pleasure: extrem. This system is very good for infinity objective and enlarger objetive (low cost). All enlarger objective work fine with this system.

Thank you for the clarification.
So then I will reference discussion already made.

It is perhaps not clear to say "traditional bellows setup". In your setup, the equivalent bellows would be much longer than standard bellows units.rjlittlefield wrote: Your diagram corresponds to the case where the rear lens has an extension that is shorter than needed for infinity focus. In that case the light from the front optics would come to a focus somewhat behind the camera if the camera and rear lens were not there. That configuration does work, and its behavior is qualitatively similar to the one that Michael talks about and that I show.
Your case is also somewhat simpler to think about. There is a fixed relationship between that focus point without the camera, and the unit consisting of camera plus rear lens. As a result, changing the center distance can be understood as equivalent to changing rear extension in a traditional bellows setup.

So, to shoot a 200 frame stack you will move the subject 4 times -- 40 pictures in the first position, then 40 pictures in each of the other 4 positions.ploum wrote:- Use a manfrotto plate for each round trip (40 picture with 1/4 mm precison each) = 10 mm for delta E.

Do I understand this correctly?
--Rik
Yes rik if you want and don't forget software ZS ...
yes for 200 pictures 4x50 or 5x40. For x20 it's better x50 because delta W is small.

Frederic did i get this right:
1. Distance between the Raynox and the 200 mm lens is 18 cm on the average? You change this distance for stacking by 2 cm, so it varies from 17 cm to 19 cm?
2. What is the distance between the 200 mm lens and the microsocope objective (or enlarger lens) In your drawing you show a diaphragm and some rings.
I'm still curious.

1. distance between raynox and 200 m lens is 10 cm. I change by stacking = 1 cm or a little bit more.
2. 25 cm dipahragm is not very usefull. I close when i don't use this system for dust.
Rings : on the front 42 mm on the back 58 mm. And a retro system for tube lens with 42 mm rings Inside 58 mm rings.

Yes it's 25 cm but it's was long to change my system before it's was a bridge. with raynox for stage 2.
But that's done well no ?

Frederic, thank you for confirming this number. If this is the case you have probably built a two-sided telecentric system in your first stage, as the distance between the two elements appears to equal the some of the focal lengths. Placing the diaphragm in the common focal plane makes the system two-sided telecentric, if the diaphragm is the limiting aperture. This is different from what i assumed the first stage to be, with a spacing of the elements that is much smaller. I doubt that the formulas given by me apply to that situation, and i have to think about such a combination.

Surely there must be some communication error.
If the diagram is to scale it looks more like 4 or 5 cm (=40 or 50 mm).

Yes i have change this distance now = 25 cm !!!
I use infinity lenses. Distance is not so importante ?
Not telecentric 80 mm < 210 mm for dcr 150...
Distance is enough for create an virtual image behind L2 and adapt size image to my sensor.
Similar with that
L1 = objective + 25 cm + lens tube
= 25 cm !!! I use infinity lenses. Distance is not so importante ?
