Description follows:
This is a custom built rig for stacking macro photography. The Tee extrusions have three feet for stability.
The subject support post is adjustable side to side, the slide for height. T
The entire slide mechanism is adjustable fore and aft, and is dovetail mounted to this adjustable plate. The bellows is Vivitar, has an Alpha camera mount (other mounts can be found on eBay), M42 on the lens side. The bellows runs on high precision linear slides, and is moved by a high precision, backlash free lead screw inside the box. At the end of the lead screw is the actuating lever which incorporates a one way clutch bearing. The lever rests on a stop pin. There are 10 threaded holes that accept the travel stop pin. Movement occurs by lifting the
lever until it contacts the stop pin then letting it return to rest pin. Minimum increment is .001 imperial, maximum .010 imperial (.0254 to .254mm). There is approx 75mm total travel available. To return the bellows, pull the lever off the shaft, install backwards and rotate clockwise until back to the starting point. Someone clever with electronics could easily add a small stepper motor and integrate with remote shutter release to automate shooting for stacking photography. (Arduino anyone?)
There is a custom mount that slips over the lens end plate of the bellows to mount a ring flash, and there is substantial adjustment available along the lens axis. A number of lenses are included, largely enlarging lens, and microscope lens, with adapter tube.
In no particular order, lenses include:
