Hi, I've bought an M6 mark II with kit lens recently and did some testing of the kit lens to check if I got a decent copy. I was really disappointed with its performance at 45mm. Photos were really unsharp. After testing various hypotheses I was able to pin point the problem to shutter shock. I did some ca 1 sec exposures from a tripod and they went out good using both electronic and mechanical shutter, so I tested shorter exposures handheld with IS and voila! Here are the results (the test was not as thorough as in the existing shutter shock thread, but the results leave no doubt.

I expected to be happy with the new camera with much improved sensor and was going soon to buy more lenses for it and an EF adaptor for my already owned EF ones. Now I wonder if I should return it and keep my 700D or maybe make a warranty claim. I get same kind of softness also at 1/125 and 1/160. This is unacceptable in my opinion. I'm going to contact Canon support about it, but have little hope to get a helpful reply.

To other M6 mark II users - do you notice shutter shock with this lens with the same level of blurring as on those 100% crops from the centre of the frame?

Ouch - not good at all.

I tested my 15-45, 11-22 and 22 prime and I can't see any noticeable difference between mechanical and electronic shutter. Tried 1/60 and 1/80 second exposure.

The 22 prime does not have IS so I would have thought it would be more susceptible to shutter shock; but I can't see any difference.

From what I've read, when there is shutter shock it is actually caused by the IS, so lenses without IS don't have it. None of my primes show it. I was able to see it a little with my 11-22 in the 1/20-1/100 range. It's not an issue for me, because I can simply use electronic shutter with the 11-22 if the speeds are going to be in the affected range. The only other lens with IS that I use a fair bit with the M6II is the 70-200 F2.8L IS II. But I use that for sports, and am never shooting at slower speeds than 1/500 with it, so I've never seen shutter shock with it. I haven't bothered testing, to see whether it can be affected by shutter shock at slower speeds.

Perhaps there's an issue with your 15-45 lens. Do you have any other lenses to test?

Phil.
