Canon EOS 40D: Mounting Lens

Video Transcript

"Alright, so you've got your flash card installed in your camera, you've got your battery, and now you need to take some pictures. Before you do that, you need to put your lens on your camera. So with the 40D, you have a cap over the body of the camera, protecting the sensor and the shutter, from any light or dust. You should keep this cap on the camera, anytime there's not a lens on the camera, to protect it from getting dust in there, or anything else that might damage your sensor or lens or mirror. So, to take this thing off, what we're going to do is, there's a button on the left side of the camera, if you're facing the back of the camera. It's going to be on the left side. And, what you're going to do is press that down, and then twist the cap off. It should just come right off. And what I've got here is a Canon 35mm, 1.4 aperture, fixed focal length L lens. Any Canon EFS lens, there is a white dot on the body of the Canon, where those lenses will need to line up. But, any Canon EFS, any Canon lens that is not an EFS lens, will have a red dot instead. In this case, I have an L lens, which has a red dot on the lens, and there's a red dot on the body. And those two dots should line up when you put the lens on the body, and then you can twist the lens on. In this case, I'm going to be twisting it, twisting the camera on, the lens onto the camera clockwise. So, what I'm going to do is line up those two red dots, and then twist the lens, until it stops. And you don't need to press hard, it should slide in there pretty easily. Once the lens stops, it's locked in there, and you can't twist it any way. It's just, it's there. If you want to take the lens off, again, what you're going to need to do is, press that lens lock release over here on the, on this side of the camera. And what you're going to do is press that down, and then just twist the lens off counter-clockwise. It should come off pretty easily. But, like I said, you don't want to leave that exposed for very long, so, either keep a cap on the body or a lens on the body. A lot of people like to keep their lenses stored in a case to protect them, instead of leaving them on their camera body, because they're expensive."
