Its taken on the Sony. I don’t know why the EXIF data did not get into the image, though there is a clue in the filename! Probably a box in the export dialogue that I forgot to tick.
Incidentally, if you want to record which lens images were taken with, Exiftoolgui (Windows only) seems to work well, once you get used to how to use it. If you use Lightroom, Lenstagger is good (it is a Lightroom extension and uses Exiftool, which is a command-line program) but Exiftoolgui is standalone and does not need Lightroom.
To Bill, the lens is one of those designed to be used with Bellows, so, though it has an OM mount, it will not fit directly on to the camera and needs either bellows or an extension tube. I use it with an adustable extension tube that came with the lens on ebay. The method is to extend the tube till it is approximately in focus, and then use the focusing ring on the lens to fine-tune the focus. I got the lens to get a bit more distance between me and bugs, so I am less likely to make them fly off. But I haven’t used it that much because I decided I preferred an even longer focal length. For nervous insects, 400mm or 600mm are better! But you are right: I should use the OM lenses more often because they do make you slow down and think, and being designed for manual focus, they are better for that. You generally need to turn the focus ring further than on autofocus lenses, which makes it easier to adjust the focus precisely.
