Nikon DK-17 Eyepiece

Installed this on my D780 and the optical clarity is exactly what I expected from a genuine part—crisp and clear right to the edges.

The click when it snaps into place is reassuringly solid, and it fits my camera's viewfinder perfectly. I grabbed a spare for peace of mind, and it's nice knowing I won't have to squint through a scratched-up lens anymore.

Finally found a proper spare so I'm not stuck squinting through a scratched viewfinder when I'm out shooting. It clicks into place exactly like the original, and the fit is snug enough that it doesn't wobble during a long day of walking around.
