感覚的不一致を生じるという短所がある。The optical type tJ has a simple structure, is small and lightweight,
In addition, in order to confirm the optical image (b) with 11 vision, it has the advantage of having a better resolution than electronic ones, but because of the good resolution, it is difficult to record images. This has disadvantages in that it causes a perceptual discrepancy between what is reproduced and confirmed, and a perceptual discrepancy between what is confirmed through the viewfinder and the reproduced image.

,) 'l' N) Liquid crystal:, child, dynamic scattering type (1)
SM) Liquid crystal element (which has a middle circumference, and all of them are driven by this) In the case of YIJ L, it has the property of acting as a transparent body, and is used in the viewfinder optical system. A light-shielding plate 8 is provided closer to the subject 1 than the pins 1 to plate 3, so that the optical image '4 can be visually observed through the eyepiece 5. When checking, move the light shielding plate 8 in the direction of the arrow A corner to remove it from the imaging light area, and when checking the recorded image through the liquid crystal display panel 6, move the light shielding plate 8 in the direction of the arrow I3. It moves and advances into the condensation light area, and f(k product list i7,
When there is no IJL, the optical image 4 is transmitted through the eyepiece 5. , te[-j
When driving the liquid crystal nail plate 6, the light blocking plate 8 extends into the imaging light area, so that the raw image 111 can be viewed through the eyepiece without being influenced by the imaging light beam 1]. By looking at l-1 through 5 and confirming, it is possible.
