I am using a canon 60d with an NA60D, Tomkina 10-17, 20mm extension and 8 inch dome
When shooting at the wider end I am getting a reflection I think in the dome that's at the top of the images. The reflection is being generated from the internal flash
As I zoom the lens the reflection move further out until it disappears at 14mm
I don't think it's a scratch issue as its to uniform with an arch then 3 Marlena either side, plus its symmetrical and also if I mount the port upside down its still there
How can I resolve this?
Take a look at the top of the image in the deter and either side of the arched mark
Look forward to getting some help!
