Apparently it does not work with 16bit greyscale tif images either. 
For anyone else stumbling upon this thread, there is a work-about to get the data into a numpy array.

i = Image.open('16bitGreyscaleImage.tif')
a = numpy.array(i.getdata())    # a 1d numpy array
a = a.reshape(i.size)  #2d numpy array

Perhaps there is a better way of doing it (?), but this works for me.
