Eyecup / Eye Cup for Pentax K10D K20D K2000 K100D DSLR — JJC SB7523

Replacement rubber eyecup compatible with Pentax DSLR models K10D, K20D, K2000 (K‑m) and K100D. This JJC eyecup fits over the camera viewfinder to provide cushioning for the eye, reduce stray light entering the eyepiece and improve viewing comfort during composition and shooting. The design matches the form factor of the original eyecup to maintain a familiar eye-to-viewfinder distance and framing behavior.

Advantages

The soft rubber construction cushions the eye and helps absorb pressure when pressing the camera to the face. The eyecup blocks peripheral light to enhance viewfinder contrast and make manual focusing and exposure assessment easier. Its OEM-style shape preserves the natural eye position and does not interfere with diopter adjustment or eyeglass use.

How to use

To install, align the eyecup with the viewfinder frame and press gently until it slides into place, ensuring a secure fit around the eyepiece. To remove, pull the eyecup away from the viewfinder edge with steady, even pressure. Clean with a damp cloth and mild detergent if necessary, avoiding solvents that may degrade the rubber. Check fit before extended use to make sure it does not obstruct viewfinder controls or diopter adjustment.

Usage recommendations

Use the eyecup when composing images in bright environments or when you require additional eye cushioning during long shooting sessions. Regularly inspect the rubber for wear and replace it if it becomes cracked or loose to maintain effective light sealing and comfort.
