51mm Lens Cap

I ordered it for a new scope I had gotten, and this size is hard to find. It fits the objective lenses as it should and looks to be of good material. I am very happy with the cap.

Unfortunately, we cannot guarantee the Kaiser 41mm Push-On Lens Cap would work on your listed equipment. The Kaiser 41mm Push-On Lens Cap is designed for lenses that have an outer diameter of 41mm, or 1.614 inches, so 1.625 inch or 1.630 inches may be too large. However, I would recommend that you can purchase the push-on lens cap and try it on your equipment. If it does not work for your usage needs, you have 30 days from the purchase date to return the item for an exchange or a refund.

Can you please verify if this cap will fit on a 80mm hasselblad lenses?
If the focal length is 80mm, it doesn't mean the cap/filter size is 80mm. It depends on which version of 80mm lens it is. Typically a push on lens cap should be about 2-3mm larger than that of the filter size. For example is the lens has a 77mm filter thread, a 80mm push on cap should work. The older Hassy lenses took Bay 60 filters, that would be about 60mm in diameter , so a 63mm push on cap would probably work.

Yes - I use these85mm caps on 82mm step up rings and also on a few lenses with 82mm filter threads.

can this be used on a fujifilm fujinon 135mm f5.6 rear lens?
I completely concur with Gaston. The best way is to measure the rear mount and even then i would order multiple sizes just to make sure you get the correct one and then just return the others that do not fit perfectly.
