Tamron 後鏡頭蓋 Canon EF (v2)

Snapped right onto my Canon EF lens with a satisfying click, and the v2 design feels sturdier than the old caps I've used. It's a simple thing, but the snug fit gives me real peace of mind against dust when swapping lenses out in the field.

Finally, a rear cap that clicks on without that awkward twist-and-pray alignment. It fits my Canon EF lenses snugly and keeps the dust out, which is all I need from a spare cap. Not much to say beyond that, but it does its job perfectly.

Picked up this as a spare so I'm never stuck without one when switching lenses, and it's honestly built better than the stock caps I've had before. The plastic feels solid and it seats onto the bayonet with a clean, firm click that gives me confidence it'll keep dust out for years.
