I probably made a mistake in the proportion of this filter adapter, because with the size of the G-12, I want to actually have a camera with me, which is easy to carry "relative" to the body. Now I want to have this part of the use of a polarizing filter and am thus in the situation that I yet again a camera bag, even if the smaller type, must have. Otherwise it surprises but that for this adapter such a high price is demanded: with all ancillary costs 43.45 Euro. Obviously, this also applies to the banal accessories saying: "It has always been a bit more expensive to have a special taste".
