@10FPS i wonder how long the shutter will last on the MKIII?

I have been trough 3 Canon 1dmkII's and 2 Canon 1dmkIIn's all before 35,000 shutter actuations, the shutter has failed. I do not care what Canon says about the cameras shutter life, this camera can not take the constant abuse of Burst shooting. So my real question is this; if the camera can not do it at 8, do they really think that it is going to be better at 10?
I think they should have left it at 8FPS and added some more MP to the camera, 12.9MP would have been perfect for the PJ and sports hooter, the files are not all that large to work with.

Low speed shutter and high megapixels? It's called a 5D

1D3 sollution; Just reset the maximum shooting speed down to 8FPS, or lower, using the custom functions. BTW my two 1D2 bodies had 26K and 64K activations. My 1D2N has 67K activations. I haven't had any shutter problems yet even though I use high-speed for basketball and baseball.

I know people who have exceeded 200k shutter cycles and others, who like yourself have had early failure. So production quality control probably plays an equal role in such longevity.

Canon state that they have revised the shutter manufacturing processes which include changes to surface finish and heat treatments. In addition a new drive mechanism has been employed which prevents mirror bounce and includes a dedicated motor for shutter cocking, however, looking at the white paper the no of mechanical components is up by ~10%. e.g. 675 v 616

Given that its mechanical, I wonder whether one should consider "running them in" as one would with a highly tuned engine!

Doing the math on data throughput, I can see your point on 10 v 12.9mp, but that would eat into 5D or 1DS territory, so the marketing dept probably had their say.

As others have stated elsehwere, the proof is in the pudding, so lets wait and see how it performs.

Just i am actually waiting myself. After the first round of deliveries, i suspect you will not see the rest until July. I personally have had it with their marketing games myself, (although if i was Canon i would be doing the same thing myself). i am just going to get a 1dsmkII (again) and that is going to be it until Canon releases an 8FPS 14MP camera.
Canons lenses start to be challenged at 16MP as it is, if they do go to 22MP i sure hope they Camera has the ability to shoot 22MP at a 1:3 cropped mode at high speed 8FPS or 3FPS at FF.
Hey, it is nice to dream...

Wow Anthony, that's an extraordinary run of bad luck. I know people who have put in excess of 400k frames on Mark II shutters without failure. The Mark II shutters are rated for 200k cycles; the Mark III for, I believe, 300k.

That's great, if that's a CF option! If implemented properly, this will also reduce noise! When the 'sensel' read-out speed is increased, it means that some of the photons converted to electrons will not be read fully or at all. Therefore, allowing more time for read-out will retrieve more signal which will reduce noise.

I have a 1dmkII that has about 175K on it, but i never burst with the camera! My reference is strictly to nothing other than pure burst shooting, constant. Also with the MKIII you use Two Actuations every time you shut the cam down if you leave the Sensor Clean on.

It's still bad luck. The people I know with very high shutter counts have all used a lot of high speed burst shooting. Personally I've averaged over 100k frames each on three different 1-series bodies, all with a heavy predominance of burst shooting, with only one shutter failure on the original 1D at 115k.

Now it is fairly well documented that there was a run of Mark II's that suffered early shutter failures, but that seems to have been an anomaly. In any event, the Mark III is rated for 300k cycles, and I think it's fair to say that it's designed to withstand heavy high speed burst shooting, day in and day out. That's certainly the way I intend to use it. ;-)

Personally, I would consider a camera with 175k single frame clicks on it to have been much more heavily used than one that had seen a lot of burst shooting... sort of like the difference between highway miles and city miles on a used car.

granted it has been 8 years since I worked for Canon, I left before digital became mainstream. But what the heck, a shutter is a shutter, film or digital. Point is, shutter replacements were a rare event....RARE.
I have not had a problem with my 1 series cameras, (4 film & 2 digital)
What are Canon saying, 300,000 shutter actuations. Well I would say that would be conservative.
Perhaps your experience was somehow related to a user procedure. Whatever, most unusual.
Anyhow, should a major camera problem occur it shouldn't be that big a deal providing you have a backup. As a CPS member you are guaranteed of a quick turn around by Canon & should not be without your unit for an extended period.
Anyhow..........Keep shooting & good luck. I reckon if you get the MKIII you are going to be stoked.

Best,

I would imagine that the burst shooting should make no difference to the shutter. At the insanely high speeds its components move, it probably seems like an eternity in anyway between two burst shots... Indeed, I would image that the shutter of the original 1D takes the most beating of them all, with its maximum speed of 1/16,000s and much quicker flash sync speed?

Everything else, i.e. the mirror, surely takes more strain.

I very much doubt that the technology slows down the reading speed just because the frame rate is slowed down. That would make for inconsistency.

I expect it is a custom function option that alters the frame rates because the 1D3 seems to have done away with personal functions.

5fps is fine for me, sometimes the machine gun shooting still misses the moment that I want.
