>>3586593I bought a second hand D7000, and I decided to clean the sensor because the dirt was very obvious on apertures smaller than f/5.6. I saw scratches on the sensor surface when I opened it up. Here's a test shot of the sky after cleaning it, shot at f/11. Now I can't tell if the lens also affects the image, because my 50mm f/1.8D has some traces of fungi in them. Is this acceptable?
