Brownie 127 gave darned nice pictures. Those cameras served a generation or two of American families (and other markets as well).
The main limitation was fixed focus, shutter speed and aperture that meant most people used them only in daylight or with flash bulbs.
Many of the models had glass lenses.
You can find old 127 Brownie photos posted on Flickr and see that the results were not crappy, like Lomo, at all.
