Hello, a question from a friend. A canon EF 50mm f2.5 compact macro lens, is it able to take the same shots as a EF 50mm f1.8 standard lens? I understand that one has wider aperture. Is it that the macro lens can focus a lot closer? Is that the difference and can you still use it to take infinite distance shots as with the EF 50mm f1.8 standard lens. Any help would be great.
