The 2nd curtain stopped before reach/pass the gate, the metal bar is visible, need 2-3mm further travel to reach the 1st curtain. I can see the 2nd curtain brake/stopper, but it seems not adjustable. Any suggestions how to adjust the 2nd curtain to travel further? BTW. All rollers are CLAed, it is not a need CLA saturation. Thanks

I can't offer any definitive suggestions, not being familiar with the 7. Generally, however the first curtain brake of many focal plane shutter designs will contribute to braking the second curtain, also. When the second curtain lath hits that of the first, the impact can still be absorbed by the first curtain brake. Hence, it might be worth verifying that the first curtain brake is correctly adjusted. If it's over-adjusted, it may be preventing both the curtains from travelling fully?

I adjusted the 2nd curtain stopper (possible the 2nd curtain brake, the one I circled on the photo) holding screw, the 2nd curtain is able to travel further. While Canon 7 is a capable RF camera. the build quality and design are on the cheap/mass production side. The service manual has minimal information and there is no other manuals available to understand how the shutter works. It is a Leica type shutter, but cheaply designed and made.

This thread may help you. A strip-down comparison of the Leica M4 and Canon 7. Plenty of detailed pics.

Well done!
It’s a shame you had to hammer all over the top cover to get it back on. (Ok, truly, that’s a nice look!)

First you have make sure the camera is CLAed, your issue could be related to camera need CLA. If CLA does not address the issue, then adjust the parts listed above
