I find it quiet hard to get the focus right. Since the camera app is not complete, yet, the values for gain, exposure, balance and focus have to set manually.
Despite of this the pictures come out a lot better than I'd expect.
BTW: pictures I post under #shotonlibrem5 are not modified except for size. If I'd start using the raw files to develop them manually I'd write so. These are the jpg files the camera app produces.
