What you will need:
- Small blade screw driver, or an Xactor knife used to remove the skin from the camera.
- A small Philips screw driver
In my experience, this is one of the easiest camera to remove the lens, as the images below show.
1. Using a thin Remove the skin (covering) on the front of the camera, and this will reveal the four Philips screws (in red) that hold the lens module together. Remove the screws using the Philips screw driver:
2. Once the four screws are removed, hold the lens and pull the lens module with the direction from bottom to top. The top of the lens module is still held together to the top of the camera by screws. Don't hesitate to use some force if necessary. Once the lens module is half way, as indicated by the picture below, remove all the screws that are holding the lens module to the body of the camera, and the lens will separate from the camera.
3. The picture below shows the lens module that's removed from the camera body. There are three screws that are holding the lens board to the lens. Remove these and separate the lens board from the lens. Note the brass guides at the 11 o'clock and 5 o'clock position. You will need these if you want to retain the focus mechanism on the lens. These guides are used to prevent the focus helicoid from separating from the lens.
4. Once it's cleaned up, you will end up with something like the picture below. I didn't use the built-in focus mechanism on the lens, and instead, I use a 17-33mm helicoid with 58mm opening to focus the lens. This allows a much closer focus distance, and is a lot smoother and easier to focus than the tiny focusing ring on the lens.
