Had the problem that several blades of the lens cap did not close or open fully. I fixed it in the following simple way, no tools and a little bit of primative force:

1. switch camera on, lens will extent

2. remove battery so lens will not retract automatically

3. take the front part of the lens and pull gently but firmly. with a little bit of manipulating the housing will slide off. Be carefull to hold the lens pointed upward so the parts of the lens cap will not fall off.

4. The lens cap parts consist out of 3 blades on the top and 3 on the bottom side. The top 2 can be taken off for cleaning. Keep the one with the spring attached in position. the blades on top and bottom are nearly identical. no 3 is with the spring, no2, with big pin, no 1 is with small pin

5. Clean the inside of the lens housing and the blades with some cleaning alkohol. Blow dry

6. clean with canned air the inside of the lens if necessarry,

7. if problem was caused by a dent in the lens housing or blades, put it on a flat hard surface and press with fingers or blut tool from the inside the front of the lens cap in the original form. DO NOT use hammer or plyers.

8. assembled the blades again. no3 is still in place, place no2 with the pin down. the pin slides partly under no 3, then put no 1 on top, pin down. The whole assembly should not stick out.

DO NOT use any lubricant, oil, grease, WD40 or what so ever.

9. Slide the lens housing back over the lens. Watch the position of the printing on the housing so it slides completely in.

10. Ready, put the battery in ! and test.

Alternative if blades are damaged beyond repair, remove all 6 blades and use a plastic lens cap, or order with canon 6 new blades, hope you will get them (for free).

well.. .that was a really bad idea.. parts all over the place

Don’t give up! It took a few tries to get the shutter blades back in correctly but it worked for me, and no problems in about a year since!

Can someone who has attempted this clarify which part to hold and which part to pull?

Canon G7X with lens cover parts marked -- where do I pull, where do I hold to take it off?

In other words, which part is expected to stay and which part is expected to come off?

My first G7x mki lens cover got stuck when I didn't notice some dried syrupy droplets on the camera. Took it apart and applied rubbing alcohol to the blades and it was back to normal. Sold it off to try the G5x (has the same lens) before giving it to my mom. So far no issue with that one.

Earlier in the week, I saw a used G7x mki with an occasionally sticking blade on the cover. The owner reduced the price quite a bit so I decided to revisit this camera. Pulled off item 1/2 in this photo to expose the blades and cleaned them up. It seemed to be all fixed but then started sticking again. After a careful look, I saw that the flange on part 1 between the lettering of IS and 2.8 was slightly curved in. Took it apart again and rubbed a blunt round end of pen plug on it to bring it back to true. That appears to have been the real issue.

Auto lens caps do nothing for me. They are the first thing broken on cameras displayed in stores. The exception were the Olympus Stylus with their neat sliding shell design.
