At one point in time I shuttered at the thought of even looking at my camera's sensors.
While two camera bodies reduce the amount of lens changes it still has to be done for longer glass along with the fisheye.
So after reading about this years ago I decided to give it a go.
I clean my cameras a necessary and if it's dust that is always in the way it's time for it to go.
After years of cleaning i'm never afraid to tackle this job......
