[0.14 lb] So I bought a used 23mm F4 lens for the GFX medium format system from B&H used department. When I got it (at a great price) the lens was like new but had the wrong size cap with it. I let customer service know they asked for a picture of the wrong part, I sent it. They (B&H) just sent me the proper (new) cap at no charge. They have good people.

[0.14 lb] Nice to see I can Fuji OEM lens cap to replace my lost lens cap.

[0.14 lb] Nowadays, products just don't deliver as they promised. But this lens cap does. It snaps onto the front of an 82mm lens, such as its new intended best friend: my Fujinon Zoom. It keeps most light and dust out, and more importantly, keeps the magic gremlins that live in my lens trapped inside, so they can't get at me or my loved ones during the dark of nighttime.

Truthfully, I do occasionally think of the raw materials cost of plastic pellets, and comparing the actual materials cost as a percentage of retail price and what the start to finish markup is. But percentages don't matter when you're just trying to keep your glass clean. It's better, I found, not to think about those types of things.

The spring-loaded squeeze tabs that easily allow you to disengage the holding mechanism work brilliantly. They are MUCH better than the old style lens caps we used to have to glue into place. There's no sloppy mess on the glass, and you don't have to pay for glue (I always got nasty looks when purchasing, because the clerks knew I was too old to be building airplane models, and they thought I was feeding my glue-sniffing habit).

Overall, I'm glad I purchased this, and my lens is too, who used to complain that having no lens cap was like walking around without underwear. And pants.

[0.14 lb] A cap for all seasons.

[0.14 lb] This cap is more comfortable to pinch compared to the original cap. Nice!

[0.14 lb] It's perfect. OEM to replace the original I lost like a bonehead.

[Front] This is a flat lens cap like what is on the new fuji 23mm f/2 lens. After trying that lens and lens cap, I did some research to see if there was something similar for the fuji 56mm f/1.2 and discovered this. Why is it better? With the original rounded lens cap on the 56mm there was often a doubt as to whether it was seated completely. One side would be completely in, but the other would be just barely hanging on, and then the whole thing could easily pop off. Not sure from a mechanical perspective how the flat designed lens avoids this problem, but it does. It just seems to pop into the deepest thread of the lens, every time. I think maybe the trick is in available surface to push the cap in. On the rounded lens caps, you fingers are simultaneously squeezing the raised ridges together to compress the cap, and also trying to press in on those same points to push the cap into the lens, and as you release the ridges it is somewhat intuitive to pull away from the cap, thereby pulling part of it back out of the lens. On the flat lens cap, your fingers have more surface area to press against the lens cap, even when releasing the compression spring. Hey, I'm not an engineer. Do I know why a glass of water quenches thirst? No, but I know it works.
