Kaiser anti-Newton glasinzetstukken

The anti-Newton surface is doing exactly what it should—my medium format negs are finally flat and free of those annoying rainbow rings when I focus. They slide into the carrier without any fuss, which is more than I can say for other glass inserts I've wrestled with.

Fit them into the K4583 carrier and my scans came out tack-sharp, not a single Newton ring in sight. The glass sits perfectly flat, which makes loading the negatives a lot less fiddly than I expected.

I was worried about getting Newton rings with my medium format negatives, but these inserts make every scan crystal clear with zero distortion. The glass sits perfectly flat in the carrier, and I've noticed a huge difference in sharpness compared to just using the carrier alone.
