I have an 18-135 lens on my t3i, after returning from vacation I notice a spot on most of my pictures. It is harder to notice when the aperture is wide open, however when closed all the way down it appears as a dot on the photo; I tried cleaning the lens ( both ends) and it does not go away, any one have any idea what this could be? it does not appear with other lenses so I know that it is a problem with this lens. I have attached 2 photos, of my wall as it is easier to see on a solid color, one with the aperture wide open the other all the way closed. If anyone has any ideas please let me know

Edit: I just closed the aperture on my other lens and it is there, so hopefully its just dust inside

it's on your sensor...it'll show up with every lens...it will show up more when you stop down...

either run the auto-sensor clean on the camera a few times, or you can just try and get a rocket blower, and blow on the sensor with it to get rid of it...

go into the menu and find something like "clean sensor manually" and it will guide you through it. if you search on you tube there is probably an instructional video.

you're going to need a few things before cleaning it...it's not something to go diving into without knowing what you are doing...
