This is pretty cool. I have a Target 620, but I don't believe the lens could be flipped on it... I wouldn't want to as it belonged to my Grand Father and I don't feel right modifying it. I would like to get my hands on a Hawkeye, though. Respooling 120 onto 620 reel is a pita. Which Hawkeye will take 120 reel, or will all of them? Thank you!

A meniscus lens can have some advantages in image quality over a plain convex lens. But it got more spherical abberation.
Wrongly orientated this gets even worse.
But as the examples above show, the image is dominated now by angular abberations. The reduction of which was actually the benefit of the meniscus.

Love the photos Marvin, are you in any of them?

I'm no optical wiz so this may be a stupid question but what are angular abberations?

I chose a ambiguous term. What I meant was abberations in image-forming of points situated substantially off-axis.
Manifesting in the total image off-center.
