Ia a small essay really necessary !
Check out the Sigma 70 mm f 2.8
If you own two cameras you can afford two memory chips.
It would have been instructive to view the damage that occurred. (before and after)
It's a nice technique, called "Tenting". It has all types of configurations (For stationary subjects.)
For the individuals suggesting lenses..........I use a collection of GOOD enlarging optics, no shutter. Expose with light source.
One thing you can do is take a shallow vessel with water and watch the surface for movement. I see this in restaurants within water glasses.
Something as simple as a passing car, refrigerator, forced air heating.........I've seen lab experiments with lasers placed on two ton granite slabs to eliminate vibration.
Vibration is the number one problem. Proof of this can be seen in the construction of atomic resolution microscopes. The system floats on a computer controlled foundation.
There is a problem with extreme magnification using glass lenses; "Hollow Magnification" However, I doubt this is your problem.
I see, by your equipment image, you are using aluminum/wood......Your problem is vibration; Not enough mass. I do science photography. My unit is an old German 8X10 enlarger base of cast
iron and filled with lead shot. I have used bellows up to 48 inches with no problems. A micro adjustment for focus is a must. Also.......I don't use a shutter, I expose using strobes with a "Tent"
to control light distribution and angle. A dark studio is a big help.

We have two situations put forth.........Forensic ( scientific methods and techniques to the investigation of crime) Post camera manipulations (Artistic achievement) There are "truth in advertising laws". I think we can all understand the difference.
Then why didn't you say it.

If possible....Good agent
