first SLR 680 model model was introduced in 1982. It uses 600 integral
film, has a sonar and an intergated electronic flash. The top of the
line so-to-say. The original
price was $265, only slightly more the the SX Sonar from 1978. There
was a second version (SE) with minor changings to the trim. In 1996 an
new version was released, the SLR 690. In this model analog
metering/timing circuitry had been replaced by a 4-bit microcontroller.
It was very expensive in the beginning (just under $ 400). Prices
dropped as it became quite popular. By 2000 it disappeared from the
markets except Japan.
it's the top of the line camera and a real SLR, prices are still very
high. The Sonar
and the flash might be handy, but add to the size of the camera. In my
opinion the 680/690 cameras are more fragile than the ordinary SX
cameras. 3 of the 4 I bought were defective and had to be sent back to
the seller. As they were reknown sellers, this wasn't a problem, but be
cautious before you invest quite a sum. I prefer the so-called SX 670,
a SX70 modified to use 600 film.
