Sensor Cleaning :-(

Got back from the beach to notice the same two marks cropping up in all the blue sky pictures whilst I can photoshop out the marks having cleaned the lens off best I can I can only assume it's grot on the sensor nothing visible when selecting mirror up.

Touching the sensor worries the bejesus out of me can't definitively prove it's not the lens until my new one arrives

The spots are at the points of each A although I'm not sure it will be visible in resized photos hence the two crops..

Cleaning the sensor freaks most people but seriously, it ain't rocket science. If you can read and follow simple instructions you can clean your sensor.

I highly suggest the Carson Sensor Loupe so you can really see what's on your sensor before and after cleaning. Without this, you can't really tell without taking more photos. I consider it absolutely essential.

....

That certainly looks like a useful tool to add to the collection.. Cheers

Just purchased a can of Dry Air it has resolved the issue.
