### ⭐⭐⭐⭐⭐ Necessity is the mother of invention or in this case, inventiveness
*by  on Reviewed in the United States August 7, 2026*

Recently for my foray back into Large Format photography, I purchased a FUJINON 180mm f5.6 Large Format lens the came with no lens caps, neither front nor rear. The front was no problem. It had a threaded 67mm filter ring and I had a few 67mm lens caps that would grip filter ring threads with no problem. The rear element was a horse of a different color. The rear lens opening was smooth on the inside and there was nothing for a thread gripping feature on a lens cap to grip. And to make the situation a bit more difficult was without any threads, any lens cap employed would need to be a slip-on variety and the rim’s outer diameter was 51mm, a bit of uncommon size in my experience. So after looking around, I found this 51mm slip-on lens cap and ordered it hoping it would work. Well it fits perfectly, slips on smoothly and holds fast until it is slipped off just as smoothly. I’ve always heard necessity is the mother of invention or in this case, inventiveness.

### ⭐⭐⭐⭐⭐ Works as it Should
*by  on Reviewed in the United States January 11, 2025*

This item fits quite tightly which definitely keeps it from falling off my telescope. The downside, it is nearly impossible to fit to the scope when the temps are in the low 40's. Once the scope warms up, the caps fits as before. Except for transport, I don't put the cap on until everything warms up anyway, so it really isnt too much of a problem. Would buy again if I lose this one.

### ⭐⭐⭐⭐⭐ It Fit!
*by  on Reviewed in the United States September 6, 2026*

It fit just like I needed it to.
