So you’ve noticed a few spots on your images and you’re sort of thinking that you may need to clean your sensor. Do you wait and go and take it to a camera store or do you attempt to do it yourself; well if you are brave enough then there is a video below which shows me doing it and how I’ve gone about it.
Also below is a link to a cleaning kit on amazon which I used for cleaning but please do get the right size for your camera. If it’s an ASP-C then get the ASP-C version not the Full Frame as the sticks will be to big for the sensor; not as important the other way around although you might leave streaks on your sensor so I wouldn’t advice it.
