Seeing Scotts macro shots using his rig I thought I would post some macros here using a simple macro reverse ring and a 50mm "D" lens with adjustable aperture ring.
The ring is a simple metal ring with a bayonet lug on one side and filter threads on the other. You click the bayonet mount into your camera body then screw the 50mm lens, filter end, onto the mount ring. If using a "D" lens you can adjust the aperture from lowest to highest for more DOF. If using a G lens (AF-S) you will have to use tape, or similar, to hold the aperture tab open.
There is no metering with this rig. There is no auto focus with this rig. You simply take a shot and adjust as necessary. Camera will need to be in Manual mode and you set shutter speed and ISO. Aperture will not be adjustable in camera. You focus by moving the camera closer or farther from the subject.
As you can see focus is kind of hard to get just right on a very small subject such as sugar crystals. Larger objects are easier and the smaller your aperture the more of the subject you can keep in focus.
On the series of shots below I was at ISO 200, I changed aperture from f/1.8 with shutter speed of 1/4000th, to f/8 at 1/2000th then f/11 at 1/750th second.
