Used on my Canon 5D MkII, magnifier certainly allows the sensor to see but it is very bright, it is almost impossible to spot dust in others, on the other hand, the stylus whose contact surface No. is washable or replaceable, seems inefficient, it is becoming impossible to work with the microscope. The stylus cleaning has been effective but still I operated blindly Pear, by cons can be very useful to dislodge dust, but this type of utensil is for less pharmacy. Not convinced so.
