I'll bite with one setup that works pretty well on DX format, and because it is very light and small allows for hand holding, even though it has no focus or aperture control at all.
The picture is a couple of years old, and the head shown is no longer in use. I now have Kirk ball head. The Manfrotto head shown was jerky.
The camera is a D3200, in manual mode of course. The lenses are from a turret set that came off a Compugraphic typesetting machine. The range of those I have varies, in part depending on how far they're inserted into the holder, but they work pretty nicely down to about 1:2 or a little more. The aperture of the lenses is approximate, but seems to be around F5.6 for the shorter ones, F8 or so for the longest, which is about 1:3.5.
The adapter is a Konica microscope adapter with a Nikon bayonet retrofitted. The rail is from a Minolta auto bellows, which was beautifully engineered in two pieces. The tripod pad was home made originally for a Nikon F, the rear section cut off so it would stow better in the case. Current Kirk setup has a home made Arca pad. The flash is a Nikon SB-15 on a tilt adapter from some bubble pack rack long ago. Because it uses a cable to get past the tilt, it also serves as a hot-shoe to cable, or cable to hot-shoe adapter. The built in flash works pretty well too. It's all manual, of course. No metering, no TTL, etc. here.
Of course, there's not much Nikkor in this rig. For Nikkor goodness, I have the 85/2.8 D tilt shift lens, which is very nice despite not going deeper than 2:1 without extensions, but it's also heavy and the home made rig is easier to hand hold.
