So you got your nifty fifty lens and you have been taking some sharp shots for an unbeatable price. Everything is going great until you try to remove the lens from your camera and it won't come off!!!!!
Yes it has happened to you. That $100.00 lens is holding your much more expensive camera hostage. Well you are not the first. I too have had my lens stuck. I did a lot of research when it happened and this is what I found. Some people said to just twist hard and the lens should break and come off. Others said that they twisted hard and the lens came off but it wiped out the camera side of the mount, meaning the electrical connection pins. The local camera repair shop had no idea what I was talking about so I decided to give it a go on my own.
What happens is that there is a snap on plastic dust cover on the mount end of the lens. The dust cover is basically a plastic ring with four fingers that snap into the back of the lens housing. The cover encompasses the inner lens and also surrounds the electrical connections on three sides. Hopefully you are starting to get a picture of the part I am talking about. What happens is that one or more of the fingers that snaps into the back of the lens breaks allowing the dust cover to fall slightly back towards the camera body. When you go to rotate the lens to remove it the lens only rotates maybe one quarter of a turn and will not rotate any more. The plastic dust cover has snagged on the cameras electrical connection.
So here is how I removed my lens without damaging my camera. The actual glass lenses pop out the front of the lens housing pretty easily. If you are able to grab the lens outer housing with your hand and then get a small screwdriver to pry on the focus ring you should be able to remove the lenses. When the lenses pop out they will be attached to the lens housing by a ribbon connection. if you are very careful you may be able to save this ribbon. I was not able to but I think given another chance I could. Now if you get a pair of needle nose pliers you should be able to reach down into the lens housing and grab the dust cover right where it will rotate over the cameras electrical connections as the lens rotates in the direction of removal. If you can pull it away from the camera body as you rotate the lens you should be able to remove the lens with no snags. Most important is to lift the leading edge of the lens dust cover as it rotates over the connections on the camera body. If you want to make it easier to see then just rip the connection ribbon on the lens and set the lens assy. to the side. Make sure your pliers are clean so as to not have dust/dirt fall into your camera body.
There you have it. Make sure it is your $100 lens that is sacrificed. Not the lens and your $600 camera body! Kill your lens and get inside of it so that you can lift the dustcover away from where it is snagging. It is not worth strong arming the lens off and hoping your camera survives when your lens is one fifth or sixth of the cost and is already broken to one extent or another.
I hope this helps someone in the future. I will try to get some pictures up. feel free to hit me up if you need them and they are not up yet,
