SPECIFICATIONS
(Specifications and nechanisns not described in instruction manual and catalogues are described here)
1. Outline
This canera is intended to promote our company' s position in the amateur market by improving operability by using a dial: also by reinforcing the AF and AE, using Five-Point AF where up and down areas highly evaluated in the market, the superimpose indication where visuality has been improved, and Ten-division Photometry.
2. Superimpose Indication
The focus area is indicated using a segment of diffusion type liquid crystal for superimposition: it is arranged between the screen and penta-prism
When the grid pattern indication for composition is custon selected, the liquid crystal for superinposition indicates the grid pattern for composition.
When the background is dark the focus area is indicated by illumination using the segment, Which radiates and diffuses the liquid crystal segment for superimposition with the superimposition LED.
The liquid crystal for superimposition also indicates the center concentrated photonetry area 012 which is always lit up _
Moreover , this superimposition liquid crystal should be driven, when the power is turned on, to secure the finder view. Accordingly, when the battery is removed or alnost used up the finder view turns to black (at the level of F11) .
When the superimposition lighting is set to automatic (initial value) according to the brightness in the custon setting with a value of BVn Avo 2.5 or more, the LED for superimposition does not light.
BVn: Brightness Value of the photonetry elenent corresponding to the AF selected area AVo: Lens open F value (In the case of AVo < 3, it is assuned to be AVo = 3. Except for CPU built-in lens , it is assumed to be AVo 0.)
