Here’s the first example of the images you can expect from the Holga lens. F8.0 does mean you need well lit environments to get a sharp picture however this landscape was taken from a moving train, making it even harder to get the right sharpness of subject.
Although I don’t like the 1:1 picture ratio, the redeeming quality is the support of central composition – the uniformity of the photo (being a square) compliments symmetry.
