The camera and lens that sister holding might be a Kyocera (former Yashica) Dental-Eye medical macro solution produced in the 1990s. Contains a Yashica YC mount 35mm film body and 100mm F4.0 macro lens that cannot be focused to infinity, farthest focus is 1:10-1:15 magnification, and down to 1:1 magnification.
As early as 1962, Nikon (日本光學Nippon Kogaku) had produced a set of medical macro equipment Medical-Nikkor 120mm F4.0, and later upgraded to Medical-Nikkor 200mm F5.6 in 1972. Both could focus down to 2:1 magnification, with the aid of a 2X close-up attachment lens. Considering 1:2 magnification rate is the standard of macro lens in the film era, that Medical-Nikkors are marvelous human engineering wonders.
In the pre-digital era, Canon was no more than a mere puppet comparing to Nikon and Olympus in the professional domains.
My pa and grandpa are another dermatologist and obstetrician/gynecologist respectively, they used to own a dozen of Nikon, Olympus film bodies and Nikon, Sigma, Olympus macro lenses, but never a Canon one.
I once dropped and ruined a set of my pa's favorite Olympus OM-1n and 50mm F3.5 macro in my childhood, that was a stylish vintage film body with the biggest brightest viewfinder in 35mm format, great for macro photography.
