Because the dioptre range of the DiMAGE 5 is heavily biased towards negative values, users who require a strong positive adjustment are at a disadvantage. Would it be possible to have some sort of 'add-on' correction lens, similar to those available for the Dynax etc models? As you have pointed out, the diopter adjustment is ranging between -5 and +0.5 on this model. Any diopter attachment is not applicable due to the exterior design. Thank you in advance for your kind understanding.
