VIEWFINDER vs PARALLAX ADJUSTMENT
As the built-in viewfinder of the camera has no device for parallax adjustment, a separate view-
finder is recommended for all lenses except those with normal focal length (50mm and 35mm for
Canon Camera Model VT and 50mm for all the other Canon Cameras). A variety of viewfinders
are available for Canon Lenses. Among them are :
(1) For use with Canon Camera Model VT and later models: ZOOM FINDERS " S " and
"L" SPECIAL VIEWFINDERS V, L U M I - F I E L D VIEWFINDERS. When used on
the Camera these finders are mechanically coupled to the built-in rangefinder of the
camera and parallax is automatically compensated as the lens is focused.
(2) For Canon Camera Model IV-S2. II-S and all other cameras prior to Model V T . use
SPECIAL VIEWFINDER V, with FINDER COUPLER, which has parallax compensating
adjustment. Since cameras prior to model VT arc not mechanically coupled to the
viewfinders for parallax, you have to adjust the parallax manually by adjusting the
parallax compensating scale of the FINDER COUPLER to match the reading on
the DISTANCE SCALE of the lens. By doing so, the field you see through the
finder will be identical with what the lens will register on film.
Note: Even those viewfinders which are not designed for Model VT, Canon can be used on the Model
VT earners provided that parallax compensation is made manually.
