Nikon is capable of making state of the art lenses -like they showed with the 14-24mm d2,8 zoom;

BUT

it seems difficult for them to make a rear lens cap that stays on.
I have several lensen and several lenscaps and am allways stuggling .

Some fits on some- and other on other and i have tot take care to don't mix them up.
I am sure at some point i will damage a lens because the cap does not stay on.
some caps from sigma and tamron sometimes are better.

I would very much to spend some more money to buy a good metal bajonet lenscap if it exist.

would any one know if there are alternatives to the poor plastic nikon cap?

plaease let me know

I don't know the answer but would recommend ebay for such things. If it existed there is probably a Chinese company on ebay selling a knockoff.

The knock-offs, older vintage and third party (Sigma, Tokina, et al) brand rear caps are the problem as I see it. I use nothing but Nikon LF-1 rear caps and they don't give me any problems on any lenses.

I've never had a problem with the standard Nikon bayonet caps. The cheap, white, plastic ones go right into the trash.

A few years ago I bought a bulk package of generic/third-party rear caps from KEH. Of the 20 (?) caps in the package, maybe 2 or 3 were as good as the Nikon version.

I had few problems with the nikon rear lenscaps in 25 years.

After many years they wear off a bit. I glue a layer of a black tape on the contact surface and they are good for another ten or more years.

A revolutionary high end gadget would be a third party rear lens cap for nikon with an included fixing mechanism and release knob, fixing the lens like on a camera body.
