Tokina FíRIN 20mm F2 FE AF er en autofokusversjon av FíRIN 20mm
F2 FE MF vidvinkel for Sony fullformat med E mount.
FíRIN 20mm F2 FE AF er designet spesifikt til å passe
Sony E-mount kamera. Størrelse og vekt er nøye avveid for å balanere godt på kamerahuset og for at systemet ikke skal bli større enn nødvendig.
Keeping along with the basic development concept of the previous
model FíRIN 20mm F2 FE AF is made compatible to auto focus and other
functions of the camera providing perfect functionality and usability
for the photographer.
Ring-shaped ultrasonic autofocus motor
For AF drive system FíRIN 20mm F2 FE AF adopts quick responsive and
silent ring-shaped ultrasonic motor. Coupled with GMR sensor AF system
performs fast and accurate focusing.
Full compatibility to AF system
FíRIN 20mm F2 FE AF is fully compatible with Fast Hybrid AF system.
At all AF mode settings including DMF, FíRIN 20mm F2 FE AF provides the
same auto focus performance as with common E-mount AF lenses. Fine
manual focus adjustment is also possible.
MF Assist function
Accurate focusing is supported by compatibility to MF Assist
function, when fine focusing adjustment is operated by manual rotation
of the focusing ring with the simultaneous interlocking with image
enlarging function and bar distance display on the monitor.
Due to the data transmittance ability via electric contacts the
camera obtains necessary data from the lens chip to correct shading,
distortion and lateral chromatic aberrations. Optical corrections can be
done by the camera as well.
By transmitting focal length data FíRIN 20mm F2 FE AF is able to get maximum use of In-Body Image Stabilization of the camera.
Aperture fully controlled by camera
Camera system takes care of the lens aperture providing full compatibility to all shooting modes.
Note: FíRIN series lenses are developed and manufactured in accordance with Sony-licensed specification.
