Is this dust in lens or on sensor?

Dust on the lens, or the sensor? | Talk Photography

· With DSLRs it is a fact of life, changing lenses lets dust into the mirror box which eventually finds its way onto the sensor. I went through a period of stressing about it a few years ago. I wasn''t happy unless I had clear blue sky shots at f/22. I soon realised that the effort of habitual cleaning to achieve this was far greater than just cloning the odd spec out in the one or two ''real ...

There are steps you can take to minimize the dust (holding the camera with lens mount facing down while changing, not changing lenses ...

Are these spots on the sensor or the lens? Photography ...

· That is dust on the sensor (well the IR filter over your sensor), dust specks in the lens are not capable of causing spots on the image like this. The reason you can see them at a small aperture and not at a large one is that the light rays are far more linearly aligned at f22, hence they cast a shadow remember the surface of the filter where they sit is not ON the sensor, but close to it.

Dust on the sensor vs. in the lens? Photo Forumming

To get an idea how large an obstruction can be, catadioptric or mirror lenses have a large mirror in the center of the front element which light diffracts around.

Larger spots would normally mean the dust is in the lens while smaller ones are dust accumulating on the sensor. Sharp prominent spots can also be seen and are usually dust on the sensor.

· You can''t see the sensor through the viewfinder, so that''s a separate issue, most likely dust on the mirror or focus screen, maybe in the viewfinder itself. Get yourself a rocket blower and give it a good blow, then get a visible dust swab kit and give the sensor a clean. Don''t shoot at such high apertures, f/11 is plenty for almost all situations.
