Really cool! thanks for sharing.
Thanks 
,of course I did not reinvent the wheel here except the idea of the reel that I have never seen nowhere
When my film is dry,I put it directly on the Paterson reel,like that,no dust at all on my film
I never tested the antistatic brush,maybe it is good but I have a doubt
Maybe that will give some ideas to someone
The nisi rail is very precise for UP and DOWN but it is not a right angle so I think I don’t keep it
That’s a great looking system, very substantial, heavier duty than the Reprostativ Bausatz Höhenverstellbar which has been mentioned on here.
I would have thought that it was almost inevitable that there’s going to be some play (slump) in a macro rail with that weight of camera and lens, could you not just have an adjustable baseboard to compensate?
Thanks ,the problem with this nisi macro is when you tighten the screw to avoid oscilliations,there is a little gap about 2mm on the left side (see photo)
The only solution and the most simple is to tilt the valoi to get the perfect alignment
PS : Sorry for my bad english🇫🇷
Thanks for the picture, 2mm does seem rather a lot I agree. I suppose these macro rails generally tend to be used more or less horizontally, could it be shimmed out at all? In principle macro rails with a lead screw offer much finer adjustment as opposed to those with side adjustment on a rack and will not tend to creep when held vertically. On the other hand for vertical slide scanning we only need a very small range of adjustment because the copy stand will get the camera to more or less to the right position so someone with some engineering skills and a milling machine could make something much more precise and without any play.
Still it is quite common to have to adjust for this with vertical copying systems, I have a separate baseboard underneath my negative holder and get away with a couple of card shims (set up initially with a mirror) but Mark D Segal uses threaded bolts at each corner and @gihlsong uses these incredible vernier adjusters.
Sorry, only just watched your video, you clearly don’t need any advice on engineering!
Get something like this to adjust camera angles: https://www.amazon.de/Bresser-Stativkopf-Feinverstellung-Fotomontierung-Verwendung/dp/B07RY9LQTS/ref=mp_s_a_1_3?crid=38NIEWEBGVSVK&keywords=bresser+mh-100&qid=1674909459&sprefix=bresser+mh-100%2Caps%2C100&sr=8-3
Rather,I take all the informations ,very informative,thanks Harry
Digitizer,yes it seems a good option but I try to avoid the pieces between the stand and the camera at most.More there is mechanism between them,more there is movment in my opinion but I believe you,thanks for the information
I use components that make sure all parts are aligned, ARCA clamps and plates plus custom L-bracket on camera. Thus no need for adjustments.
Yes,but in my case I use the inclinometre to adjust the last 0,0X° ,takes me maybe 30 seconds so it’s ok for me
Ok ,I just try the difference between manual focus on grain vs autofocus and look at 200% and I don’t see any difference with my gx8 so I put the macro rail nisi back in the drawer
Maybe it is because my gx8 with olympus 60 2.8 macro give me only about 8mp…
I suppose with a FF 40MP and a macro lens like the sigma 105 2.8 macro art,the différence will be visible
