Canon Drop-In Clear Filter A

Finally, a way to keep dust off the sensor when I’m not using a variable ND or other filter. The clear glass does exactly what it’s supposed to without affecting image quality.

Used this with the drop-in mount adapter and it’s perfectly flush, so no extra dust worries. Came in handy when I wanted protection without altering the image at all. Solid build for the price.

Finally, a clear filter that doesn't degrade image quality—the glass is perfectly clean and doesn’t introduce any unwanted haze. I use it with the mount adapter to protect my sensor when I'm not using a special effect filter. It snaps in firmly and feels reassuringly solid.
