Yes, I'm aware that the 7-14 requires a different lens cap because of the design, that's why I mentioned after market push on lens cap. It's not an entirely unique design as other lenses in the past have used push on lens caps.Thanks for your advices. The problem is that this lens has a fixed lens hood so you can't use a standard cap. Panasonic does not deal directly with private customers so I must get my dealer to contact them. First time ever I lost a lens cap and it was this one. I have contacted the dealer!
