Fotodiox 替換用長型後鏡頭蓋 相容於Contax G 35mm底片測距儀鏡頭（取代GK-R2蓋）

I've been hunting for one of these tall rear caps for ages since the original got lost in a drawer somewhere. It fits snugly on my Contax G lens and keeps the rear element fully protected when it's just sitting on the shelf. Solid little piece of plastic for the price.

Finally, a replacement cap that actually fits my Contax G lens without being loose or too tight. The plastic feels solid and the bayonet mount clicks securely into place, just like the original.

I was worried about finding a cap for my Contax G lens, but this one fits perfectly and feels sturdy enough to keep dust off the rear element. It’s a simple replacement that works exactly like the original, which is all I needed.
