Dynamic range of 1D Mark II is...

[Pekka]

"The dynamic range of the EOS-1D Mark II sensor is approximately 9 stops."

Pretty impressive.

[CyberDyneSystems]

Nine!

That is a substantial improvement! I don't know what the 1D and 1Ds are,. but the 10D is about 6-7... if I remeber correctly. Two more stops.. that will be very nice indeed.

Couple the extra exposure lattitude with the superior low ISO noise and it will be a match made in heaven. 8)

[Jesper]

Says the Canon technical director Chuck Westfall himself! 9 stops is a LOT better than the 5 or 6 stops of most digital cameras. I hope this means that cheaper DSLRs (especially the successor of the 10D!) will also have such a large dynamic range.

[MediaMagic]

Very impressive indeed.

I've tried to avoid these 1DmkII threads like the plague (with zero success I might add). Each time I read one, I can smell that hole burning in the bank account. I've been saving for the 1Ds, but it's getting harder and harder to wait.

[ChrisNardone]

D$@% it! That's the first statistic that hasn't fallen on deaf ears for me. Oh well, good thing I'm so patient and can wai...
Sorry I gotta run.

[iwatkins]

Oh hell.

I had talked myself out of the MkII after the launch then you go and post something like this.

9 stops ? That is close to perfect for most landscape shots (in the UK at least). Most of my landscapes usually have an 8 - 10 stop range, measured with a Sekonic spot meter, with some reaching 12 stops. This is outside what the 10D can do so I have to bracket, then combine or use ND Grads.

But a MkII would be able to handle most situations in a single shot apart from maybe sunsets.

The real killer is that I have the money sitting in the bank as savings, but the missus thinks that is to go towards a deposit for when we move house (which we never seem to get around to doing).

Maybe I could get the camera and then say the bank burned down or something ? :twisted: :twisted:

Oh dear, oh dear, oh dear. It has started. Camera lust, worse than drugs.

This is incredible. This camera walks on water. I bow to this camera.

9 stops! WOW! That's incredible!!! :shock:

I would take that post w/ a grain of salt since you have no idea what the poster really means by 9 stops of dynamic range. Depending on what exactly is meant, you can even claim that a top prosumer digicam as well as most existing DSLRs have 9 stops of dynamic range because they can apparently capture image details that vary by that much although not necessarily all in one capture. Also, it could be some "rated" value that cannot be achieved in real world usage.

Think about it. If it's truly what everyone's wow-ing about, don't you think Canon would make a big deal about it in their press release? Afterall, you're talking about a revolutionary leap in dynamic range. Fuji made a big thing about their "new" double-photosite SuperCCD technology designed specifically for increasing dynamic range long before they had a camera to show.

So I would take that w/ a big grain of salt.

Well, if its anything like the 1Ds, the D60, or the 10D were when originally introduced, it will perform as advertised and beyond. I don't doubt the 9-stop range, but the proof will be in the pudding.

[Man-Fai Wong]

Believe what you will. But I would wait for some reviews first, if the main reason for spending the $$$ is the supposed increase in dynamic range.

For one possible explanation of this 9-stop range, you might find this discussion of interest from a few months back on DPR's Canon forum:

http://forums.dpreview.com/forums/read.asp?forum=1010&message=6320537

In it you will find direct reference to a page in a review by Phil Askey that suggests that many good digicams probably have somewhere near 9-stop range IF you include the extreme non-linear portions of the sensor's response curve.

It all depends on how you interpret the data. And we have no idea how that poster's quote should be interpreted.

BTW, Tom, I'm not sure if you understood the significance of 9-stop range as seemingly assumed by some of the others, but I believe they are thinking 2-3 stops greater range than your 1Ds, 10D, etc., which have typically been considered to yield ~6-6.5 stops.

This sort of thing happens in all industries. In the audio world, you have power ratings, frequency response ratings, etc. being hard to decipher. In the video world, you have claims about contrast ratios and other ratings that are obviously meaningness. In the car world, you have mileage ratings being hardly truly representative. And so on...

Take it FWIW.

I understand it quite well - if true, it is a quantum leap. Non-linear portions of the curve are of minimal value, which is why they weren't considered in Canon's present DSLR lineup. Unless the electronics can accurately compensate for the non-linear portion of the curve, that portion isn't useful.

This sort of thing happens in all industries. In the audio world, you have power ratings, frequency response ratings, etc. being hard to decipher. In the video world, you have claims about contrast ratios and other ratings that are obviously meaningness. In the car world, you have mileage ratings being hardly truly representative. And so on...

If you know the parameters of the power ratings and freq response data, it isn't difficult to decipher. Contrast ratios share the logrithmic scale, but they follow similar rules. I've spent a little time with audio and electronics, though my experience is more closely related to basic transistors and vacuum tubes (though the math doesn't change).

I can't speak for the EPA mileage estimates, other than to say that they have been pretty accurate for the last 10 years or so in my experience.

I think by virtue of being in search of a good argument, you are dangerously close to misrepresenting facts. I don't mind someone searching for a good argument.

Everything is relative.

Relative to a straight line (linear) part of response curve, most digital has 5-6 stops, slide film has 3 stops, and negative has 10 stops. You are quoting the linear part of the curve, which in a vacuum has 9 stops of range. So when we say 9 stops we are talking about a straight line response curve. To make it easier, just think of the Mark II as having a 13-15 stop curve.

That aside, 9 stops of linear range is garbage on an S30 as compared to a 1D. You get into the corners of the range, and you will die a slow noisy death. You are comparing an S30's digital range to a 1D ! Come on. See the noise stats on 1D Mark II relative to 10D and 1Ds.

Anyway, that's what happens to people who spend a little too much time on dpreview. :roll: :lol:

I know y'all are thinking 9 stops linear. My point was simply that we don't know that's what the Canon rep actually meant. If he said 9 stops linear, then ok.

Nobody claimed 9 stops linear for the S30 (or S50 in Phil Askey's review/comparison). The 9 stops claim was for the entire curve, including non-linear portions, which was my original point. The linear portion is roughly 5 stops for the *better* digicams, which is roughly what's commonly accepted.

BTW, the review that was referenced was for the first(?) Fuji digicam that used their SR SuperCCD that claimed increased dynamic range. That was the reason for the closer look that Phil took.

No offense intended. :wink:

But my point still stands... Your post makes it sound like this is misleading information. Having read enough of Chuck's posts, and taking into account that the general public thinks of 5-6 stops as standard, my point is that it would be misleading for a Canon rep to quote stats that are not apples/apples.

[CyberDyneSystems]

I have the utmost of faith in Mr. Westfall,.

...And I have allready excepted the MkII into my heart as the "One True Camera"

[J.A.F. Doorhof]

Ok,
I was not so intrested in the camera but this is COOL.
At the moment I use bracketing shooting if I want more dynamics, but this is also nice :D.

I don't have the money for the Mark II but I'm a bit more certain that when the 10D II will come out (whenever) I will upgrade immediatly.

We have Pekka, CDS and RFMSports here to prove if the 1DMKII has 9 stops. (Though I tend to believe that it's true.)

Yes, I do hope that a 10D Mk II will have 9 stops and ETTL II.

[defordphoto]

I am not a measurebator. I will not shoot 8.2 megapixel pictures of rulers. I will not spend my time with my new $4500 camera proving focus issues or 9-stop issues. I will spend my time shooting real-time photographs and I'm confident I'll produce some of the best photos of my life this year with the MKII.

Whether it has 9 stops of dynamic range, or 10, or 8.34998 +/- .2346677 stops is for the measurebators to spend the next year arguing about. While they are arguing, I'll be shooting. I am also pretty sure that CDS and Pekka will also be shooting, not measurebating.

Yes, I understand (and I have never done any test myself). But knowing a DSLR with 9 stops is exciting. Sorry for asking anyway.

Yep. All I reported was what Canon technical director said. I'm not going to interprete it or try to prove it. I'm sure you will see plenty of demo photos from varying situations which will tell if the dynamic range is wide enough for not having to think about it so much.

I'm looking forward to getting mark II because I have shot too many times in situations with 10D were Mark II's features would have been invaluable: focusing in low light (way off target), AF not tracking subjects properly or at all, hiding the camera from slight rain or snowfall, shutter freezing totally in very moist and hot rock concert, waiting for buffer to come back alive when people wait impatiently for the next shot, getting odd 'shutter does not respond'- moments in critical moments, missing lots of shots because of slow operation, being worried about storage reliability, being worried about camera reliability, having to think flash metering too much, not being able to compose accurately (95% viewfinder) and reshooting again and again because of that etc. etc.

I want to forget the camera. Getting the main thing (composing and being there, also mentally) easier and being able to think less about the gear performance and more what you shoot - that is why I will gladly pay 5000 euros for mark II.

[Man-Fai Wong]

Ilya,

No offense taken. My apologies for perhaps sounded a bit harsh. I tend to be a skeptic, so you can certainly call me one. :D

BTW, I did a search over in that forum to see what Chuck Westfall have said about DR for previous Canon DSLRs, and apparently, this is a first time he's given numbers. In a previous post from last year, he said Canon doesn't quote DR figures.

RFMS,

I don't like to measurebate either. But it's certainly good to know roughly what exposure range one has at his/her disposal though. If there's a quantum leap in capability, I'm sure most any serious photog would want to know. Afterall, Pekka didn't start this thread for nothing I imagine.

Skepticism aside, I certainly would LOVE to see such a quantum leap just like the next guy/gal, especially if it trickles down to the low end in the not-too-distant future.

Mark,

My understanding is your print would only hold about 5 stops max, maybe a little less in practice. Don't know if there's much room for improvement there.

What an excellent point :!: I think this has always been the case, and perhaps it was just about ironed out in the film world - but then here comes that evil - new technology :lol: New wrinkles for Canon (and the other guys) to solve, and new capabilities to exploit. In its own way this is the part where the journey is the fun part. Each new round of camera bodies gets better and better.

Now, if Canon is listening, about that reasonably-priced full-frame sensor... :roll:

Very well said, Pekka, and since I can't say it any better, I'll ditto all of the above. As much as I love the 10D I also find myself stifled by its limitations.

"I want to forget the camera." That's beautiful.

[CyberDyneSystems]

Well said,.

At one point I was concerned that the AF on my 10D was going to the dogs.. (it turned out to be caused by a UV filter and a zoom lens that didn't get along)

Honestly,. it is simply something I have never contemplated... nor have a read a single thing on the subject.. (ie: how to measure your camera/films dynamic range capacity)

If I had read something,. I would remember it,.

I guess the simple solution would be to set up indoors with unchanging lighting and shoot a grey scale chart.. and first shoot with even exposure,. then start shooting consecutive shots,. increasing the exposure compensation up untill the highlights blow out,. and then down untill the darkest greys are reduced to pure black...

or should I shoot just a mid grey... no scale?

But I don't think that would be too scientific...

The EOS-1D Mark II has the best dynamic range among the 4 cameras you've listed.

>> What is the dynamic range of the 1Ds, 1D and 10D? <<

More than 8 stops but less than 9. There are slight variations according to model, but they are insignificant.

>>How does Canon determine this? Do you shot an image at f/8 then go 4 stops down from there and 4 stops up past f/8?<<

Canon Inc. shoots accurately exposed RAW files at the base-level ISO of the camera and measures dynamic range from a linear conversion of the RAW data. Further details of the measurement procedure are unavailable. Note that effective dynamic range when images are processed to a standard tone curve may be less than the total dynamic range of the sensor itself.



There you have it... Man-Fai was correct to be sceptical :(

Still,. it nice to see that Canon regards the Mkii sensor to have some improvement,. even if it is based on there own measurements to be "maybe" 1/2 of a dubious stop better than the 10D etc.

But the "9 stops" seems to NOT be a reason to upgrade on it's own.

Too bad,. 3 more stops would have been amazing! :)

..... //trouble is,. now that none of these numbers reported are wholly quantified by the manufacturer.. especially in relation to others assesmments of CCD/CMOS DR... it looks like I may be FORCED to do some serious side by side MEASURBAITING My self!!!!! :shock: :? :roll: :wink:

Yeah well, we'll see when it gets in our hands. Doesn't reduce my excitement one iota!!! The MKII will become the standard by which all others are measured.

[By S]

Nine! That is a substantial improvement! I don't know what the 1D and 1Ds are,. but the 10D is about 6-7... if I remeber correctly. Two more stops.. that will be very nice indeed.

Yes two more stops would be nice if it were so...but it isn't. Chuck Westfall says the 10D is over 8 stops.

EDIT: I see someone else has posted this info. Sorry for the duplicate.

Also for what it's worth, I've measured my 300D at over 8 stops. So I find his numbers to be quite credible in real terms.

[CyberDyneSystems]

8 stops,. really.... :shock: I'm surprised these numbers aren't being touted louder by Canon. I am quite sure that most digitals are a mere 6 stops.

[ilya]

Will the wonders never cease ...


>>How about this request for 1d or 1d Mark-II, a custom function that would allow focus dependent shutter release instead of shutter button release priority?<<

I'm assuming you mean in AI Servo AF, since focus-priority release is already standard in One Shot AF. If so, then I think you'll be pleasantly surprised by the performance of the EOS-1D Mark II. By speeding up AF calculation with a new high-performance dual-CPU design, the Mark II is designed to get accurate focus with single shots in AI Servo AF or the first shot in a burst. This way, you get the benefits of a release-priority system in terms of capturing the decisive moment, together with the predictive AF accuracy you need with moving subjects.

If ya want, I can right up a quick tutorial on how to really "fix" up yer monitor to only display the same 6 stops :lol:

No problem, just use Canon's special 'Luminous Paper'. It gives you about 8 stops, and glows in the dark.

Price/sheet and radiation are issues, though.
