I love the fact that things which you need a manual for, like a PC (or Mac) do not come with one. But every time I buy a lens, which normally has one or two controls, it comes with a manual!
Granted, it tends to say things like (actual quote from a Panasonic lens manual):
"Take care not to drop the bag that you inserted the lens in as it may strongly shock the lens. The camera may stop operating normally and pictures may no longer be recorded. Also, the lens may be damaged."
How wonderful is that?
It also say twice "not to put a lot of pressure on the lens". I'm not even sure what that means. Not to say things like "this is a very good lens" when the lens can hear it?
And it says "do not carry the unit when it is still attached to the camera body". I suppose when the lens is on a camera, you can only leave it sitting at home on a table.
Aaaaaand it informs me that it should not be stored "where there is fire". Good to know.
