General Brand 49mm/52mm ステップアップリング

Was worried this would feel loose or add vignetting, but it fits perfectly flush and even the 52mm filters I’ve stacked spin on without catching.

I was a little worried about vignetting, but this ring is so slim that my 52mm polarizer works perfectly on my 49mm lens without any dark corners. The anodized finish also makes it easy to screw on and off without getting stuck.

Finally, a step-up ring that actually screws on smoothly without binding. The threading is precise and the 52mm filters I have attach perfectly to my 49mm lens.
