HD Twin-Lens with No Adjustment for Image Acquisition
The distance between the two lens axes is approximately the same
as the distance between the human eyes, to provide easy-to-view,
natural-looking 3D images. The HD twin-lens system is set with a
distance of about 60 mm (2.3 inches) between the two lenses.
The lens axes, viewing angle, rotation, and gradation are
pre-adjusted before the components are precisely
assembled. This eliminates the need for lens adjustment
before shooting. Camera operations such as focusing,
zooming and iris adjustment are also synchronized for
the left and right lenses.
The new twin HD lenses were designed exclusively for
FULL HD 3D image acquisition. They boast low chroma
aberration and high resolution, and deliver superb color
reproduction, detailed nuances and crisp 3D images
even in dark scenes − with minimal flare and ghosting.
A built-in 5.6x (approx.) optical zoom function, which
extends from 47.1 mm (35 mm equivalent) wide angle to
264 mm (35 mm equivalent) telephoto, covers a wide
viewing angle that is well matched to 3D content production.
Convergence Point Adjustment Function
The convergence angle between the two lenses is varied inside the
optical unit. This moves the convergence point (the reference plane of
the 3D image) in a fore-and-aft direction to control the leaping and
depth effects of recorded objects, and acquires natural-looking 3D
images. The convergence point can be adjusted easily by using the
CONV (convergence) dial* while viewing the L/R-MIX image on the
LCD monitor.
*The dial function is switchable between CONV (convergence) adjustment and IRIS (iris)
adjustment.

Display Functions Assist 3D Image Acquisition
The LCD monitor and viewfinder of the AG-3DA1 both display a
variety of information to assist 3D image shooting and ensure superb
3D effects.
•3D Guide: This displays numerical values for the distance range of
the subject to achieve better 3D effects while viewing. Natural-looking
3D images can be captured by using the displayed information as a
guide. This function offers two modes: Guide Display 1 mode
assumes playback on screens that are 196 cm/ 77 inches or smaller,
and Guide Display 2 mode is designed for a screen size of 508 cm/
200 inches.
•Convergence Point: This displays the numerical value of the
convergence point together with the 3D Guide to assist adjustments.
•L/R-MIX Monitor Image Selector: The image display on the LCD
monitor and viewfinder can be selected from three modes: Left Lens
(no mode indication), Right Lens (R-IMAGE) and Left/Right Mix (MIX).
*When the subject is located outside the distance range indicated by the 3D Guide, it may
result in a double image or an unnatural image without proper 3D effects.
