ProMaster Eyecup – Nikon DK21/DK23

Finally found a replacement eyecup that actually stays on my D300—the rubber grip is snug enough that it doesn't pop off in my bag.

Lost my original eyecup years ago and this replacement snaps on perfectly to my D90. The rubber is firm enough to stay put but flexible enough to fold my eye against the viewfinder comfortably.

The original rubber piece that came with my D90 finally cracked, and this replacement fit perfectly right out of the package. The material feels just like the original and snaps on securely without any wobble. My viewfinder is now comfortable to use again.
