The Mamiya "Z" lenses are the latest, designed for the RZ-67 (hence the "Z" in the lens name) instead of the RB-67. These two cameras differ in flange distance.
Lens chronology for the RB-67 is available here:

Re: Lens recomendation for film reproduction
Hmm, an extension ring will cause a similar problem as bellows, except for the lack of flexibility. If you want more magnification, I'd recommend using a 1.4x teleconverter. It will allow your lens to work as it should in terms of focal length and close range correction, while giving you a magnific...

Re: Raynox DCR-5320 as tube lens - experiences and comparisons?
Thank you so much, I really don't want to inconvenience you but that would be very helpful! Both those Mamiya lenses sound really great but I think I'd rather have the ability to use them short-focussed and/or bellows too (though mainly for full frame and bigger) - but I wonder how you mount them i...

Re: Rio Bigal Reserve: Ecuador II
Wonderful photos, as always! The feeding leech is especially remarkable! I've never seen that. I am confused about the ID. If I'm looking at the right photo, Paul calls it a "land planarian". But Wikipedia tells me that "leech" is phylum Annelida, while planarian is phylum Platyhelminthes. Visually...

Re: Lens recomendation for film reproduction
The important thing here is the proven importance (now proven again) of maintaining the floating elements in their correct position for the desired magnification. This is a very general rule.

Re: MEJIRO GENOSSEN FL0530 4.0/110 FLOAT LENS TEST IS FINALLY ONLINE
You probably know this, but be aware that optimization is not a simple process. The 85MV (and I presume also the FL0530) changes focal length as the CAS ring is adjusted. Thus if you simply adjust for maximum sharpness, you may just be optimizing critical focus. You need to perform something simila...

Re: MEJIRO GENOSSEN FL0530 4.0/110 FLOAT LENS TEST IS FINALLY ONLINE
my approach is to set up the subject and adjust the ring by eye at 100% live on the camera for maximum sharpness (actually I use a display monitor) without regard to the magnification scale. That is also my approach, and the recommended approach for medium format photographic lenses with floating e...

Re: Raynox DCR-5320 as tube lens - experiences and comparisons?
I have made those comparisons shorty after Nathan published his tests on this forum, but it may take me a while to search for them on my old hard drives...currently for full frame my favorite 200mm tube lens is the Mamiya 200mm Apo for 6x4.5 and my favorite 250mm tube lens for FF is the Mamiya 250m...

Re: Lens recomendation for film reproduction
"Absolutely, macro lens set at minimal extension, i,e. Infinity focus when mounted on the bellows which also at minimal extension. Thank You Rik for suggesting the correct term “infinity focus” …." Yes, and that is the reason I made my comments about floating elements being out of place. The results...

Re: Lens recomendation for film reproduction
I will consider you suggestion of using medium format bellows with reverse mounting of macro lens. Actually I was suggesting the medium or large format bellows with the lens mounted inside it IN THE FORWARD DIRECTION, not reversed, with the bellows extension set to maintain the correct flange-to-se...

Using repurposed Nikon Multiphot base for slide copying with Nikon Z6II attached to Nikon bellows PB-4, Micro Nikkor 60 mm 2.8 (got this at KEH @ $140) and flat LED light source (Apurture Amaran at 6000 k). Both slide holder and macro lens hood 3D printed. The setup yielded very good quality digita...
