Out of the box, complete macro flash kit
“One lens can not use the ring flash at all – the 11-22 mm wide angle which is a good macro lens as well. The reason is that is spreads out to a 72 mm filter thread, much larger than the normal 67 mm thread. The TF-22 CAN be used with the 11-22 mm lense because it has a double threading, with the second for the 72 mm filter thread on the 11-22 mm lens making it an exceptional wide angle macro lens.” – By HMMWV
This is the way to go for macro shots
“I use this flash system for macro shots. I considered a ring light but I wanted the shadow detail one gets from two point sources. The flash units can be positioned in an almost infinite number of positions, 360 degrees around the ring, pointing in or out of the focal path and up and down relative to the subject. You can even direct the flashes to bounce off a reflector. The flash control is very similar to the FL-50 flash, it looks like the same housing and the same controls. I just wonder why Olympus doesn’t just combine the two units into a dual use controller with the ability to control the twin flashes and a standard one point flash.” – By Steven L. Nelson

Olympus STF-22 Features & Specifications
The Olympus STF-22 Twin Flash Set is a set consisting of the TF-22 twin flash, the SR-1 shoe ring, and the FC-1 macro flash controller.
This kit allows for precise and exact lighting control when shooting macro work. Flashes can be positioned at any desired angle to provide the best illumination of the subject when texture and detail are needed. Can be fired as a single or dual flash unit. When fired together, left/right balance can be precisely controlled.
At the time of this writing, the SR-1 Shoe Ring 1 (which is needed to use the twin flashes) is only specified to work with Olympus’ 11-22mm, 14-54mm, and 50-200mm lenses. It does not affix to the filter threads, and as such it is highly unlikely that you would be able to use a lens from another manufacturer.
• Flash ratios can be adjusted in 1/3 EV steps, from 1:8 to 8:1, left to right. Or only one flash can be used.
# • Offers TTL auto flash and manual flash capability when used with the FC-1 macro flash controller. TTL AUTO (GN 0.7-11 control with 1/8EV step)
# Manual (GN 0.7-11 control with 1/3EV step)
