This video contains a great deal of technical detail and should help you understand everything you need to start taking pictures at extreme magnifications. I have deliberately not included sample images in this video. This is to allow the viewer to focus on the technical details without distraction. A followup video, demonstrating this setup in use, with many example images, will be forthcoming (Going Deep - part II).

Stuff you will need for 5X+ macro photography, as described in detail in the video. This list may work for for other, similar objectives - provided they are infinity correct with planar correction and built in achromat or apochromat chromatic aberration corrections. It WILL work with the Nikon CFI Plan achromat 10X/0.25, M25 infinity corrected objective used in the video. https://www.atlantamicroscope.com/Nik...

Both setups also require the use of a Raynox diopter (4.8) - DCR-150 (https://www.amazon.com/Raynox-DCR-150...) and either a set of bellows or enough extension tube length to reach the focal length of the Raynox (208mm) minus the flange/focal distance of your camera body.

Parts needed to mount Raynox in normal orientation:
▪ camera body
▪ extension tubes or bellows to fit your camera mount
▪ M42 to your camera mount, reversing ring - this example is for Nikon F-mount (https://www.bhphotovideo.com/c/produc...)
▪ M42 to M43 step up ring (https://www.amazon.com/Fotga-Black-42...)
▪ Raynox DCR-150 (link above)
▪ M52 to M49 step down ring (https://www.ebay.com/itm/Bower-49mm-5...)
▪ M25 to M52 objective adapter (https://www.ebay.com/p/620752119?iid=...)
▪ Nikon CFI Plan 10X achromat infinity objective (link above)

Parts needed to mount the Raynox reversed (my preference):
▪ Camera body
▪ Extension tubes or bellows to match your camera mount
▪ 52mm reversing ring (in your camera’s mount) (https://www.ebay.com/itm/52mm-Macro-L...)
▪ 49mm to 52mm step up ring (https://www.ebay.com/itm/49mm-to-52mm...)
▪ Raynox DCR-150 (reversed)
▪ 52mm to 43mm step down ring (https://www.ebay.com/i/151831400966?c...)
▪ 55mm to 52mm step down ring (https://www.ebay.com/itm/55mm-52mm-55...)
▪ M25 to M52 objective adapter (https://www.ebay.com/p/620752119?iid=...)
▪ Nikon CFI Plan 10X achromat infinity objective (link above)

Be aware that many of these adapters will be coming from China and may take months to arrive. Virtually all of them can be bought from sellers such as Thorlabs (thorlabs.com) and Edmunds Optics (edmundoptics.com), but expect to pay about ten times the price.
