RE: Tamron style lens caps

[Alan Chan]

So far I have only seen Tamron, Pentax (Tamron clone), Nikon (new style) and 
a brandless caps (Nikon clone on eBay) with this fearure you mentioned. I 
have seen Tamron at a local retailer, and B&H carry the Tamon, Pentax & 
Nikon too.

That should be "Someone" mentioned! :-(
And I might add they don't need to be Tamron brand
just a style with the center grips.
