Förkortningen betyder

FE = Floating Element System

Förklaring från Tokina

When designing a lens, Tokina calibrated its astigmatism at all points between minimum focus distance and infinity so that it will give the best image results at all settings. However, when there are large differences between the focus limits, effect calibration is not possible. A floating element system incorporates optical elements that move in proportion to the focus setting of the lens. This allows astigmatism to be corrected. Many Tokina lenses employ floating element systems to provide optimum correction of astigmatism from minimum focus distance to infinity.
