Quick answer
Choose the Canon ER-hE if you shoot with an EOS R3 and need a premium, snug fit. Choose the Nikon DK-29 for Z-series cameras when you want a budget-friendly upgrade that blocks stray light effectively.
Why eyecup compatibility matters
An eyecup that doesn't match your camera's viewfinder shape can slip off or let in light, ruining your shot. Both the Canon ER-hE and Nikon DK-29 are designed specifically for their respective mirrorless systems, so swapping them between brands isn't possible. Your camera model determines which one fits.
Price vs. build quality trade-off
The Nikon DK-29 is priced significantly lower than the Canon ER-hE, making it an easy upgrade for Z-series owners. However, the Canon ER-hE costs more because it's built for the professional-grade EOS R3 body, with a larger rubber surface that seals out dust and moisture. If you rarely shoot in harsh conditions, the DK-29 offers great value without sacrificing basic light-blocking performance.
