Nikon D7100What model is it?
What makes you think it's oil?Anyone here have any issues with oil on their camera sensor, have had my camera a few months and its been cleaned three times? had my D5300 a year and never cleaned the sensor once.
I would take around 200 shots a week, what do you mean by how i change the lenses?
Without reason to think otherwise, it's probably the common dust mote fouling your sensor.If its not oil what could it be then? what do you clean your sensor with Horoscope Fish?
Could you be a little more specific?Guys looking to try the Copperhill products anyone know where they can be purchased, their own site seems to be down. Google never found anything.
I did some poking around and everything is a dead end: Their website no longer seems to exist, their products are "Not Available" on Amazon and it doesn't look like they're coming back.Their swabs, holder and liquid,

The sensor brush nails it probably 95% of the time or better.

For cleaning I start with a rocket blower and if that doesn't do it I move to a sensor brush. The sensor brush nails it probably 95% of the time or better. For those times the sensor brush does NOT do it, I move to a wet cleaning using Eclipse swabs and fluid.

Pre-moistend Swabs (for wet cleaning (you can also get dry swabs and bottles of fluid if you want.))
