Cleaning

When I started on macro I didnt clean my lens that often, but when taking macro picturet the lens is much more sensetive to dirt. How do you clean your lens? and whats the best way to do it?

Think you will find it is not dirt on the lens but dust on the sensor that shows in macro shots.
Having tried most of the methods of sensor cleaning, I find a sensorklean pen the easiest (and also one of the cheapest). But suggest you read up on sensor cleaning before even thinking about it.

No it doesn't show on normal shots normally because you are using smaller aperutres and higher magnifications. This effectively narrows the light beam to almost parallel which makes the sensor spots show up more.
As has often been commented- nothing shows sensor dust like an MPE-65 lens at 5X magnification. The other reason for not showing in normal shots is macro shots often have much plainer OOF backgrounds.

Try taking a shot of a lightish plain background with one of your other lenses with the shot completely out of focus and around F16 - bet the same spots show.
