The lowly lens cap…. I’ve managed to keep quite a few vintage lenses a long time. Well, a few decades, at least.
But the lens caps are gone. Fortunately the UV filters screw on, and they’ve survived too.
So I started capping my best lenses with metal caps. Quite compact. Very protective. They stay put.
And yet, I’ve an admiration for the plastic ones. The lowly plastic lens cap.
Here’s an example, which I imagine came from right when Nikon switched names from Nippon Kogaku, to around the 80s as they started using the bright silver logo.
This one has a tiny little screw on top.
Any other older caps out there?
Let’s see them.
If they’ve survived all these years, they are worth showcasing and reminiscing.
Kind regards from East Tennessee.

I tend to use the newer caps with the 2 clips that I found to stay on. I do have few metal caps along with plastic slip on caps, the plastics do not seem to stay on as well as the metal caps.
 
I think this dates back to the late 1950s. 43mm size.

Lens caps have saved many of my lenses/filters over these many years and only when the lens itself was so heavy its own weight broke the lens internally, have I suffered a “loss”, though filter threads have been dented, on occasion.

Lens caps are high on the list for my 3D printer, once I have it running and if they are a tad thicker, you can be assured there is a good faith effort to make a quality kit.
 
Back when I was newsie, I had a 100mm f2 Minolta Rokkor lens that I loved and used quite a bit. I left the hood all the time and that left it unprotected. I discovered that a Kal-Kan plastic can cover fit perfectly on the hood. There are a lot of plastic lids that can fit lens or hoods; My Zeiss 300cm. f4.5 Tessar wears the lid for Fritos bean dip, my 178mm AeroEktar has a Tupperware lens cap.

Pringles can and purple port wine cheese lids (58mm) fit some of my lenses very well.

Don’t say! I think my Nikonos W and AW 28mm 1:3.5 and 35mm 1:2.5 are 58mm….
One is capped. The other one needs a cap. I Best Buy some Pringles!
Thanks for the hint.
Be well.
 
But unlike Mrs Beckham, you need to remember to take it off before you take a picture.

My favorite lens caps are the 49mm caps made by Asahi Pentax that have both the two spring clips and that have a full lip that goes outside the lens/filter. I use them on my Olympus Zuiko OM-1 lenses, never having owned a Pentax camera. Be aware, however, that a number of modern filters have too large an outer diameter for the caps to fit over the filter.
