In recent publications the problem of deconvolving multiple images of the same object was considered, and the fact that this problem can be well posed in the sense of distributions was stressed. Here we point out that the problem is still ill posed in spaces of square-integrable functions, and we discuss in what cases the use of multiple images rather than a single image can be advantageous.
