about you, but I like what Oly omd5 with it's 12-50mm kit lens is capable of doing, as here. Even in heavy rain. Most people say that this lens is mediocre, probably the one who do not have it.
But it is good enough for me at 6,3 100 ISO at 50mm.
I use it because it is my only 12mm which I like. I would be nice to have 12mm at f2.8 . I do find it is far better at 12mm than 50mm , my version anyway. I am sure Shirley would be willing to test how water proof the camera is
