Nikon LF-4 Rear Lens Cap

Fits snugly on my 24-70mm, no wobble at all. The hard plastic feels sturdy enough to protect the glass in my bag, and it clicks on with a satisfying sound.

Snapped this onto my 50mm and it's a perfect tight fit, no wobble at all. The rear element is fully shielded from dust now, which is exactly what I needed for my bag. Feels solid and secure every time I swap lenses.

Finally, a rear cap that actually clicks on securely without that loose, rattly feeling. The fit on my 24-70mm is perfect, and it’s nice to have genuine protection for the glass when swapping lenses in the field.
