Hi guys, just want to ask if you encountered a dust problems in your pictures but only visible when using a big aperture like F2.8 - F5.6. By F6.3 and up until F18, the dust can no longer be seen. I just find it really strange as the dust is not with the lens since I tried using 2 of my other lenses. Looks like the dust is inside the camera..not sure if it's in the mirrors/sensor. Could anyone share similar experiences? Please click on the sample pics below. Thanks!
Here are sample pics:
F2.8
F4.0
F5.6
F6.3
F7.1
