I recently found a working Olympus XA2, in box with the accessory flash, from a local thrift store (Indoor Flea Market, on Lomas in Albuquerque), and had a first go with a roll of Kodak C-41 B/W film. The seller had three such cameras in his booth, and I was able to find a body I could confirm worked with existing silver oxide batteries, with the box and working flash, for a good price.
I found the focus pretty easy to master, once I understood the preset focus distances involved, and could easily estimate subject distance and adjust my framing and position accordingly. Using adequately fast film in bright daylight, intermediate distances are resolved to adequate focus by means of the depth-of-field afforded by the lens aperture, which is automatically selected by the exposure system.
All of the frames I exposed came out with good focus and exposure, which surprised me a bit. I had dry tested the camera, prior to loading film, and was pretty certain the shutter worked okay, but was still uncertain of the results until I got the prints back from the lab.
I've included several images as examples, which are scans from the prints. Film scans would be sharper, obviously.
