Negative Supply 6x4.5cm 單幀 ANR 遮罩（適用於 Pro 底片載體 4x5）

The ANR glass keeps the film perfectly flat, which made a noticeable difference in sharpness when I scanned some old medium format shots. It fits snugly into the Pro Film Carrier without any fiddling, and the single-frame design is exactly what I needed for precise digitizing.

I was worried about finding a mask that would keep my 6x4.5 frames perfectly flat during scanning, but the glass surface on this one does the job beautifully. Charges nothing, because it's a mask—not a battery—and the ANR coating cuts glare noticeably compared to my old plastic holder.

Trying to digitize my medium format negatives was a hassle until I picked up this single-frame mask—it holds the 6x4.5 perfectly flat and sharp in the carrier. The anti-newton ring glass makes a real difference, cutting out those annoying halos I used to fight in scans.
