I have an oddity this week, a Single Lens Reflex camera using 110 cartridge subminiature film. The Minolta 110 Zoom SLR (Mark I) was introduced in 1976. It is an odd-looking little pancake of a camera with a 25-50mm f4.5 zoom lens. Focus is manual with a micro prism finder spot. Exposure is aperture priority with a wheel located around the light meter to the right of the lens. LED indicators inside the viewfinder indicate whether the wheel should be rotated left or right to obtain proper exposure. Shutter speed ranges from 1/50 to 1/1000 and is automatically varied to match the selected aperture.
Shutter speed can be manually set to a fixed 1/150 by rotating the selector to X (for flash sync) or to B; otherwise it is set automatically and there is no way to know what the camera has selected. Film advance is via a single-stroke lever on the bottom of the camera. There is a hot shoe for electronic flash and a tripod socket on the left side of the body for portrait-only orientation.
As with many of my cameras, i dont remeber exactly why I bought it. It simply struck my fancy one day on eBay. I've loaded a roll of rare Fukkatsu 400 color film and set off for the long weekend with it.
Camera Wiki has a good article on both this camera and its Mark II sibling.
I actually have a paper manual for this one, but you can see the electronic version courtesy of Mike Butkus.
