Please I need some advice while performing the
Dust Alert function, I am using the
smc PENTAX DA 21mm F3.2 AL Limited lens with the camera to execute the test, sometimes I get a
100% clean screen and sometimes one with a lot of dust ????
Then, I will proceed and execute the
Dust Removal function and it will be a little bit cleaner but not 100%, then once I get a 100% clean sensor (after 2 or 3 cycles), doing the test immediately again, there will be a lot of dust on the sensor again.
I am confused on how to use this function, please could you provide some guidance on how to use it ?, do I have to have the lens cap on it ?, base on the manual I have to have only Pentax DA lenses mounted, what else I should do in order to get reliable and consistent results, thanks
