Ok /p/ i just had my sensor cleaned by a friend of a friend(i live in pretty much nowhere. photo shops = non existent) and i there is no dust up untill i get to f. 16 onward. now im sort of a noob and i swear i read this but i cant remember. if it don't appear at lower apertures that means its on my lens, Not the sensor right?Pic maybe related?Google is failing me on this.
>>300816op here. Sorry for the spelling. long day.
...i hope you didnt pay him money.
Sensor dust should appear at all apertures where as lens dust varies depending on the f-stop you select.
