This should really be a WAMT (might post there too)
This morning I swapped onto my 12-40mm f 2.8 Pro and the lens cap just pinged off while I was lifting it out of the bag.......ok thinks clip it back on whilst I sort the gear.
Well it did not just pingoff it actually fell apart
. Examining carefully it looked like the construction relies on two <0.5mm lines of glue to hold it all together.........and for the life of me (glue failure aside) I could not get the thing to refit so that it looked (worked) ok
Suffice to say Olympus will be getting a call from me but compared to the apparent construction of the cap on the 40-150m Pro it is one delicate poorly designed embarrassment!!!!
Alternative action as well as getting an Olympus replacement is that get a non brand 62mm centre action cap.
