I've seen this before, but it bears repetition ....

Nice setup. The Stackshot is placed in a very cool gear setting. I noticed the use of the good old 200/4 Micro ED-IF as the infinity relay. I used similar initially for my own work but found the vignetting troublesome so now replaced it with Raynox DCR-50 instead. The eagerly awaited Z7 likely will substitute for the current D810 in my own setup.

Thank you Rick, for the link.

Yes, I remember someone shared it before, but it is still intriguing!

The photographer stitches the stacked images.  So, the vignetting would be less of a problem?

How can you replace the 200/4 Micro with the cheapo Raynox (I assume you meant DCR-150)?  Is there no problem of the degradation of image quality?

Surprisingly little quality loss, Akira. It is combined with Mitutoyo optics which are fine performers indeed, for 5 and 10x work.

Vignetting was an issue with the 200 AF Micro. Maybe I hadn't optimal position for the front objective -- will try again just for peace of mind.

That's indeed surprising.  Thank you for the confirmation.

Very fascinating! His work is outstanding and I would almost say non replicable. However there are a lot of systems that could be used by a novice, such as me, to "try" to come close enough. I use the Olympus in-house stacking for fun. After watching this youtube video I found a dead fly under the window and gave it a try. This is done with one push on the release button and the outcome is a jpg-file. I could off course stacked the raw-files myself, but I was pleased with the outcome. I understand why the specimens have to be meticulously cleaned 8)

i have also used the 200/4D AF micro and the 200/4 AiS Micro  as well as the 200/4 Ai.... the advantage of the Raynox is that i can reduce the "bellows extension" by taking rings off and make adjustments in the magnitude if i wish..   the setup shown focus at infinity for the infinity corrected objective.

i should have added that the relay lens using the Raynox was adapted after Rik Littlefield's approach (author of ZereneStacker)

I have over the years used similar setups as Bob and also consulted Rik Littlefield.  However, in the latest incarnation, I found that the required extension could be achieved by using a small yet sturdy bellows device. This allows a better weight balance of the entire rig.

The set up might have been more refined and polished, but it serves the intended purpose well and it is easily removed and something else put there instead if the need arises.

Those set-ups look so efficient and professional!

This one?



 Not so much — although I managed to get some very interesting images out of it.
