i have just a stupid question, hope you guy won't laugh, can we use those red laser pointer pen to test the len, like project it from the viewfinder through the
len, like testing the how sharp your eye can focus.... or see the distance, sharpness, etc.
<p>
If i do that, do anyone know that those red laser is it going to kill my len coating or not? just wondering? you guys may laugh at me, but... no hurt to ask
