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.

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.

Will it fit OK with a step up ring? I'm planning to use these with some lenses that have step-up rings to 82mm.
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.

Will this push-on cap fit my Minolta MD Rokkor-x 50 mm 1.7?
A 50mm lens does not typically refer to the filter threads and or lens diameter. This lens happens to take a 49mm filter but that is the inner diameter of the lens. Your lens is probably anywhere from 51-54mm. Most people buy 2 or 3 different sizes and return the ones that don't fit.
