Last year, I went for a beginners' DSLR class and noticed that a student had an expensive camera, but didn't know how to change the lens appropriately. This caused opaque spots on all her pictures (they are not dust circles by the way), which can be dirt particles that landed on the inside of her camera lens :(. She recounted that she went to the beach and changed her camera lens there... Ahah!
I couldn't find much from the internet, so I've jotted the instructions down on this post. They are easy to follow:
- Put lens on table (rear lens upward, like picture above);
- Loosen the rear lens cap without removing the cap;
- Remove the cap from the camera body, body facing down!
- Remove cap from the lens on the table;
- Attach lens and camera by aligning white dots (body still facing down), then rotate lens counterclockwise until it clicks into place.
- When changing lens, always point downwards, to avoid dust particles inside your camera lens!
- Avoid changing lens outside when it's windy.
- Never touch your camera lens!
