    I have the early box tenger 54/2 and the single meniscus lens with a small aperture in front of it is definitely able to produce sharp pictures.

    Nothing short of a test will help you there.

    I had trouble with scratched negatives on mine, but that was due to oxidation on the film plane edges and film rollers.

    I mistakenly identified my Tengor as a 54/2, it's actually a 56/2. The settings/focus discussion is fascinating. I notice that at the most distant setting, the detail at infinity is reasonably sharp as long as it's not too close to the edges and corners of the frame. The central part of the image is plenty sharp. I'll have to experiment a bit with distance settings and apertures. I've decided I don't want to enlarge my Tengor images to much more than 5x8 inches.

    Here's one at F/11, most distant setting:
