IBIS focal length for S9D C-mount port?

I am experimenting with a Leica S9D microscope and three different MFT cameras: Panasonic GX80 (GX85), Panasonic GH5, and Blackmagic BMPCC 4K. The camera is always attached using a 0.5x C-mount lens and a Cmount-to-MFT adapter. GH5 has a feature called "IBIS" (In-Body Image Stabilization) where the ...

Re: Lumix GX80 for Leica S9D

Here is the comparison of a 1"-microscope camera with c-mount attached to the Leica S9D without intermediate optics. That is very interesting, thank you for sharing! The "1x" FOV looks like a much better choice for crisp high-resolution photography/videography of specimens. I think the 0.5x will su...

Re: Lumix GX80 for Leica S9D

In this context diameter would probably be more appropriate. Most of these c mount adapters assume a 16mm diagonal at a 1x magnification factor, so even if the image field is bigger they may crop it. For a 0.5x anything you get beyond the 8mm diameter it takes to cover the diagonal of a 1/2" sensor...

Re: Lumix GX80 for Leica S9D

That's an impressive diagonal for a c mount adapter. Glad it's working! Thanks! What does "diagonal" mean in this context? I am actually pleasantly surprised at the field of view with this 0.5x camera lens. On the one hand I don't use all the pixels due to vignetting. On the other hand I capture al...

Re: Lumix GX80 for Leica S9D

Just received the Lumix GX80. Installed without any problems at all. Here is a quick first 4K video!

Manfrotto Magic Arm microscope stand

I don't know if this counts as DIY but I'm trying out a "Manfrotto magic arm" camera mount to hold up a microscope head. The contact is made simply with a strong vice grip onto the focus slider that previously sat in an articulating arm stand. IMG_20220223_062122.jpg This satisfies 2/3 of my criteri...

Re: Lumix GX80 for Leica S9D

Other than that, I get the impression you are not completely unhappy with the microscope. ;) After all that product research, I am glad things worked out so well. Indeed! And thank you for all your patient help in choosing the right microscope at the time. It is my prize possession. I am also findi...

Re: Lumix GX80 for Leica S9D

As part of my usual automation I tend to make scripts to do a lot of the repetitive work. I'm experimenting with going in the opposite direction: Today I acquired a Black Magic Mini Extreme Iso video mixing station. This has 8xHDMI inputs, which can all be recorded simultaneously in 1080p, and 2xHD...

Re: Lumix GX80 for Leica S9D

I think we will get lucky (I bought a GX85 for video as well). The crop factor reduces the camera's video diagonal to 22.5 / 2.2 * 2 = 20.5 mm. I am curious to try the GX80/GX85 with my current 0.5x reducer lens. That should have a lot of vignetting. Maybe in 1080p mode the camera could crop a regi...

Re: Lumix GX80 for Leica S9D

So, what do you think of the S9D after using it for a year? That is the five thousand dollar question! :lol: On the one hand, I love it. It's beautiful and ergonomic. The 9:1 zoom range means that I can fluidly move between placing parts onto circuit boards and then zoom in to soldering them in pla...

Re: Lumix GX80 for Leica S9D

I have now ordered a Lumix GX80 camera with a C mount adapter. I plan to try it out with the 0.5x lens initially to see if I like the camera and otherwise to return it.

I have contacted my Leica rep about the recommended 1x adapter.

Re: Lumix GX80 for Leica S9D

Currently I am mostly using the 1" microscope camera. But the test shots with the G9 worked without problem, the field of view of the S9D is large enough to prevent vigneting when using mft. At the moment I am travelling, but next week I could make some test pictures, if that's helpful for you. Tha...

Re: Lumix GX80 for Leica S9D

You would also need the 1x adapter to use the 2.5x, unless that has been updated. The 1x should cover m4/3, but you'd also need a 37mm OD adapter to hold the camera almost flat against the top of it. I think making your own is the best/most economical approach but I do have a used 1x adapter if you...

Lumix GX80 for Leica S9D

Hello! I would like to upgrade the camera system on my Leica S9D microscope with a 4K video capability. I'd like high quality for reasonable price, particularly avoiding unnecessary purchase of expensive Leica optics (approx $500 for anything that is made out of glass.) I have read the forum and it ...
