I am looking for a 112mm lens cap to fit my 50mm Fujinon GX lens. I have searched high and low over the internet but although I can find mention of them those that do (B&H for example) are showing as discontinued or Out of Stock. I do not mind if it is a Push-On, Screw-In or Clip-On and am willing to pay a reasonable amount for one along with shipping costs to the UK. Hoping someone can help? Ed Bray.
