- Can others edit my Photos
- Photos NOT OK to edit
I recently purchased 70-200 F/4L. I tested at showroom for about 20 minutes with various shots. Now at home in absolute silence I noticed that when I press the button half way for focus, it gives faint squeak sound which then continues as humming when the IS works. After taking the photo when IS stops it stops with the same squeak. Is this normal? Photos are perfect. I do not want the showroom guy to fiddle with lens. When I am outside in open I do not hear this.:blushing:
