When using the narrow apertures I notice smudges on some of my images.
Usually only when over an area of uniform colur such as the sky or water.
At first I thought it was dust on lens but it remains constantly placed when I change lenses which rules that out I think.
So I think it's muck on the sensor but i'm a bit new to photography and don't want to go making expensive mistakes.
So far all i've done is lift the mirror out the way and give a good blow with the rocket blower. This seemed to remove some but marks still remain.
Am I being picky and should just accept that this happens or is it easy to get rid of the rest of these marks.
I've put an image below to help show what i'm talking about.
All advice appreciated, especially re products to buy and technique, also whether it's best to take it somewhere instead.
