More details from Martin Professional (http://www.martin.com):
The new MAC III AirFX is versatile beam, effects and wash luminaire and is the latest high-performance 1500-watt moving head in Martin’s MAC III family. Capable of projecting a dense, hard-edge beam with mid-air aerial effects, the MAC III AirFX’s optical system allows it to adjust from a tight beam to a wash instantly for design flexibility. Beam gobo projections can adjust along the entire zoom range for a diverse variety of mid-air looks. The fully linear zoom gives no visible beam jump from tight to wide. Martin debuts the new product at PLASA Focus Feb. 22-3 in Austin, TX.
