While you do magnify the film grain this way, that's only an issue if you were printing almost as big as possible anyway. The down side of this approach is that your ...
The difference between 21mm and 28mm doesn't sound like all that much. But as focal lengths get shorter the difference per millimeter in focal length gets larger. In theory a 21mm lens should yield about a one third wider field of view than a 28mm lens. For a 35mm film camera that would be the difference between a 75º diagonal FoV for the 28mm lens and a ...
