One of the new guns, the Macro Twin Flash 2400, has two heads that can be
attached at various angles and rotated around the lens. The heads can be
individually adjusted so that lighting ratios can be controlled for optimum
lighting. It's combined with a flash controller to allow 7-step power level
control and offers TTL control using Minolta Dynax cameras. The unit has a guide
number of 24 when both tubes are used and 17 using one.
The Macro Twin Flash 1200 is a ring flash with four flashtubes, that can be illuminated independently, to provide natural lighting for very close subjects. Focus lamps help you locate the subject and ease autofocusing in the dark. It has a guide number of 12.
