Characteristics and functions
The Minolta Riva Zoom 90c was introduced in 1991. The Riva Zoom 90c is an
automatic, 3-beam infrared autofocus, motorized camera with built-in automaticelectronic flash and a 38-90mm Minolta zoom lens. f./3.5-7.7. The minimum shooting
distance is 0.75m. with focal lengths between 38 and 56mm. and 0.90m. with focal
lengths between 57 and 90mm. The programmed automatic exposure, for 100 Isofilms, ranges from 6 to 17 EV (from ¼ "with f./3.5 to 1/250" with f./22 - lens set to38mm.) And from 8 to 17 EV (from ¼ "with f./7.7 to 1/350" with f./19 - lens set to90mm.). The range of film sensitivities allowed is from 25 to 3200 ISO, with DXcoded magazines. The camera shows up with taut lines; on the upper side we findthe cantilever mount that contains the indicator panel (LCD) with total information, in
the forward position, while in the rear position there is another cantilever mount thatcontains the vision system. The rectangular black button for the "Self-Timer" function(10 "delay, which can be canceled by turning off the camera) is positioned in theimmediate vicinity of the vision system mount, with the appropriate symbol printed inwhite. The circular shutter button is contained in a depression designed to easily
contain the index finger of the right hand. The shutter button has a dual function: if
pressed partially it locks the focus (AF) and exposure (AE), when pressed fully it
releases the shutter and advances the film. This button separates the rocker selector
for adjusting the focal length ("W" to the left or "T" to the right), placed in the forward
position, from the two small soft rubber buttons for inserting the flash ("Flash + ON /OFF" ) and for the activation of the "Red-Eye Reduction" system ("Small lightning +Large lightning / Large lightning"), placed in the rear position. The release system of
the film compartment door is positioned on the left side of the Riva Zoom 90c (lowerthe black cursor by 4 mm in the direction of the arrow), to close the back, bring theparts closer together and exert enough pressure to make the shutter release again.
block. The right side of the camera continues to descend the design of thedepression of the shutter button and in the casting of the shell it has a plastic loop
under which to insert the shoulder strap for transport. On the rear side we find acantilever mount that contains the Eye-Start system sensor with ASZ (AutomaticZoom Standby) which activates and sets the most suitable focal length according to acomputerized program active between 0.75 and 8 meters. Below is the eyepiece
window and on the right the green light for correct focus (upper) and the red flash
light (lower). If the flash disable function is set, but the exposure would require it, thered light flashes with a frequency of 0.5 sec. In the viewfinder you can see: the focus
area with cancelable memory and the indications for parallax compensation in closeup shooting. Obviously the image observed in the viewfinder varies according to theset focal length (instant motorized variation). To the right of the cantilevered windowof the viewfinder there is the main switch (ON / OFF) with a sliding cursor. The film
compartment door is hinged to the right and has a transparent window for viewing theinserted magazine. On the front of the camera we find a shiny and transparent part ofasymmetrical shape that contains the flash, the viewfinder window with the autofocus
system, the light meter cell and the RC-1 remote control receiver (optional).
Continuing to the right we meet the word "Minolta" surmounted by the "Rising Sun"
Minolta. Under the flash, the abbreviation "ES" (Eye-Start) is silk-screened in red. In
the lower left corner, on two lines, "Riva" and "Zoom 90c" are silk-screened in white.
The large central protuberance contains the lens mount with sliding cover controlled
by the main switch. The characteristics of the lens are silk-screened in white: "MinoltaLens", at the top and "Zoom 38-90mm 1: 3.5 - 7.7", at the bottom. The lower side iscrossed by 6 horizontal grooves; in the center are the words "Japan" and the serial
number silkscreened in white on a black plastic label embedded flush with thecaseback. On the right, in the forward position, there is the thread for the use of thetripod and the small hole of the intentional film recovery system (to activate thefunction, press the small button located in the hole with a pointed object). On the far
right is the battery compartment cap (1 "CR5 type" battery) with sliding release. TheQD version with date back is available.
Weight 320g. excluding battery.
Length 147.5mm. Height 73.5mm. Depth 59.5mm. in the version without QD.
