marknorton Posted May 6, 2009 Share #6 Posted May 6, 2009 The shutter blades are much thinner than paper, and although you can touch them, you risk damaging them and leaving a deposit from the oils in your skin on it. Link to post Share on other sites More sharing options...

fernando_b Posted May 7, 2009 Share #9 Posted May 7, 2009 If the shutter is damaged or not, it depends on the force exerted, on its location and on the affected area (i.e. on the pressure value). Since you don't know the threshold value of those parameters, which damage the shutter, AND you don't have a dynamometer in your finger, then it is better to NOT touch the shutter. Fernando.
