When using a digital SLR camera, you can change lenses depending on your photographic needs. You can opt to use an extreme close up lens or a super-long lens with advanced zoom capabilities. Further, the focusing ring in an SLR lens can be manually adjusted when focusing rather than relying on the camera’s auto-focus mechanism.
Manual focusing provides battery power saving which is a beautiful thing when doing outdoor photography.
Precaution when switching lenses
You should always attach lenses in a clean environment to minimize the chances of your camera and accessories getting dirt, dust, and other foreign materials.
These can result in contamination in sensitive areas including the lenses and inside the camera. Your camera body should be slightly tilted towards the ground to prevent action by the gravity on flotsam in the air.
CANON MOUNT LENSES
How to mount Canon lenses
There are two canon mount lenses for those who use Canon cameras. However, the process of switching lenses remains the same even when using a different brand of camera. Firstly, there are those lenses with an EF-S design and the traditional EF design. EF means electro focus whereas the S stands for short back focus.
This means that with an EF-S lens, the distance between the sensor and the lens’s rear element is shorter compared to that of an EF lens. It is thus essential for you to ensure you buy an EF or EF-S compatible lenses when shopping around for a new lens. The liberal 1100D lens is compatible with both old and modern lenses.
Regardless of the type of lens you have bought, the following steps should be followed when attaching a lens to a camera:
1. If there is no lens attached on the camera, remove the cover on the lens mount on the front side of the camera. This applies for a new camera or if you like to disassemble the lens after shooting photographs.
2. Pull off the cover at the back of the lens.
3. Find the right lens mounting index on your camera’s body. A mounting index is a marker showing you the exact position where a lens should be aligned with the body of the camera when joining the two. A camera has two mounting indexes; one is red while the other one is white. For Canon EF-S lens series, the white mounting index is used while the EF lens series uses the red mounting index. Always refer to the user manual when changing lenses on other camera makes.
4. Align the lens’s mounting index with the correct one on your camera’s body. Always check the user manual in case there is a color difference between the mounting indexes on the lens and the camera.
5. Keep the mounting indexes of the camera and lens aligned with each other as you position the lens on to the camera’s lens mount.
6. Rotate the lens in a clockwise direction until it clicks into position. This turns the lens toward the camera’s lens release button.
