Canon News has completed a full analysis of the Canon EOS M6 Mark II and the effect shutter shock has on images. Unfortunately, it looks like this is one area in which the Canon EOS M6 Mark II is a bit weak.
The Canon EOS M6 Mark II lacks an Electronic First Curtain Shutter, which is a strange omission and does have a negative impact on image sharpness.
From Canon News:
The M6 Mark II is a hopped-up little camera that is fun to use and is an amazing performer – but the deliberate lack of EFCS on this camera reduces it’s ability in some cases to deliver the highest IQ possible. Now to be fair, the M6 Mark II (as well as the 90D) are the two most exacting and demanding cameras on the market today, as both have 32.5MP APS-C sensors when the rest of the industry mostly has 24MP. However, this makes it more puzzling as it is more prone to show the effects of shutter shock than any other camera as well. Read the full analysis
While we all love graphs and numbers when analyzing cameras and lenses, this issue probably won't be noticed by a vast majority of shooters.
It was certainly a surprise that certain lenses were very prone to this behavior AND that Canon would gimp the camera this way and release it.
Hoping for a M5 mark II
By these standards, every SLR ever made, every great medium format camera, and (god forbid) every 4x5 or larger camera, is incapable of generating a decent image. And yet the Ansel Adamses and Darius Kinseys and Dorothea Langes of the world did just that and more. (And I don’t recall seeing any whining ninny reviews of their equipment either - coincidence?)
Photography is the only art form that I know of where the equipment gets all of the credit for the result. If I had a dollar for every time someone said “that’s a nice photo - you must have a good camera“ I could afford a good camera. Gnat’s ass analytics like this - and the wholesale condemnation that comes with it - only serve to propel that myth forward. And they feel vaguely like excuses.
We’re witnessing a golden age. Photographic equipment has never been closer to technical perfection than it is right now. And yet we’ve also made major advancements in finding ways to knock them down. I think we can agree that cameras like the SpeedGraphic 4x5 and Hasselblad 500c are iconic. And results with them bear that out. But if we held them to the same modern standards, they’d be deemed unusable.
I’ve taken some pretty good photos in my four decades with a camera - and some pretty bad ones. The common thread in those failures wasn’t faulty equipment or missing features - it was the idiot staring into the viewfinder.
Totally agree with you. My favorite is the whole dynamic range/ high ISO performance debates that are never ending. Compare the dynamic range / ISO capabilities today compared that what's available in the "good old days" of film. Gettin to ISO 1600/3200 has had a tremendous impact on wildlife photography. We have people wanting to change systems because of 1 -1.5 stop of difference between two vendors when there is far more to photography than just the bodies. More is always better, but we have tools that are capable of delivering far more than the majority of photographers skillset.
Shutter shock hasn't been a canon thing because they have all had EFCS since the EOS 40D.
This is one of, or the ONLY camera that doesn't have EFCS that Canon has made since.
While you may not have had to live with shutter shock, people in other brands most certainly have.
Unlike DR which requires R&D/ Fabrication and a lot of development challenges - this is simply firmware for Canon. Canon HAS EFCS on the 90D, the same sensor that is in the M6 Mark II. It's mind-boggling that they would remove a feature that assists with resolving the most from the sensor in a camera equipped with the highest resolving APS-C sensor on the market today.
I use 2 kg shaky benbo trekker when shooting rocks and things on my desc . shutter shake wouldnt be good at all.
The thing is, you could manually enable/disable EFCS on old Canon models - on newer ones, it's always enabled and you can't turn it off. However, the bigger culprit is that Rebels use a single motor for both mirror and shutter, so the mirror always flips before taking a photo no matter what.
I presume this 'bug' be fixed with firmware...?
Or is there a reason that Canon has saddled the M6II with this 'feature'?
I rather suspect this is why they did it, given its designed to do things like high burst mode with full ecs.
And if you want maximum resolution, use a prime where it seems to be a non-issue anyhow.
and really - again, this is a feature that exists in every single Canon camera since the 40D, and even exists in the 90D. The omission of the feature may cause problems depending on the shutter speed that you are using and the lens. it can have a dramatic impact on the 15-45 and the 55-200 and I suspect the 18-150 even though I haven't tested it yet. These are some of the most commonly used lenses for the camera.
I'd rather highlight the problem, and hope that Canon can fix it. They should be able to.
This is certainly true, and to day when you do shoot a figital workflow you can see that you need just as fast a shutter speed on fine grain (high resolution) film as you do on a modern high res digital sensor, when scanning to the same kinds of output size, although there is no comparison in sharpness and clarity. The old "rule" of shutter speed no less than focal length for sharp hand held images really applied only to the standard of a 10x 8 print viewed at 2' away, just like the perceived depth of field.
I am keen to understand how is this shutter shock issue did not affect prime lenses that were tested and affected zoom lenses with IS capabilities exclusively.
understand that IS functionality has been disabled in the lens. but are we confident that even when disabled it has not affected focusing in some ways? a bug?
or is there an issue with focusing implementation specific to mechanical shutter?
I am not buying that shutter shock can selectively affect some lenses and not others if the overall size and weight of these lenses is in the same ball park..especially on tripod. not to that degree that was demonstrated with charts.
the focusing precision with mechanical shutter is affected on lenses with IS function. correct.
I suggest repeating tests with the same camera mounted on extremely solid tripod and solid flooring. I would suggest that results won't be any different regardless. even if bolted permanently to a brick wall.
