Call this a troll if you will

Call this a troll if you will, but frankly the posted Canon 5D samples don't look all that good to me. Dynamic range appears to be even slightly worse than most average DSLRs, which aren't great to begin with, and there is clearly a reduction of image quality out towards the corneds if you look at the full files. Granted, it's not entirely fair to judge a camera from minimally processed pre-production samples. But based on these samples and some of the work I've seen from the other Canon full-frame models, there appears to be at least a minor price you have to pay for full-frame.

Because I've been a professional photographer for twenty-five years. I can photograph without a light meter with a film camera. Daylight is not as variable as most amateurs assume it is.

yeah, what was the dynamic range supposed to be that day? you were there?

hard to accuse a camera of low dynamic range if you're looking at jpegs. and with nothing else to compare to. and especially if not shot with standardized methods meant to test dynamic range.

and, if you are expecting cameras that are full-frame and image quality equally perfect from center to corners in any focal length, you could be expectant for a long, long time. no camera can do that: not canon, not nikon (nikon's corporate policy as it stands right now for this issue is to just crop out the corners, no choice for you, end of story). and that corner performance is as much a function of the lens and the particular focal length, if not more, anyway.

the point is, you have a choice to use the whole image with every shot, instead of having forced crops done for you by your sensor.

can't quite call you a troll because there's a chance you really, honestly might not know what you are talking about.

If anything... I thought the camera handled DR very well. DR in in a digital sensor (like in a chrome) must be handled very, very carefully by the photographer (not the same as in B&W - your main experience, I suppose).

Phil made a few snaps that overall showed a very well performing pre-production camera.

Just my 0.02.

that you are a claimed "25-year professional" and you find it OK to comment on dynamic range, looking at jpegs shot under uncontrolled/unknown situations?

sunlight is less variable? in what latitude, what altitude, and what time of day?

you don't find that variable, hmm....never seen the sun in LA when there's smog overhead....or sun in San Francisco....sunlight is the same to you always.

you must have divine control of nature, or you've never traveled much.

I hope that's your real name, because if I need a professional to shoot my next outdoor event, I'll be sure to find someone who knows photography....or at least knows his limitations.

either he is simply trolling or he has no understanding of dynamic range

No Kidding? It's not fair at all, but you don't let that stop you. Can you stop back later and tell us how many clicks to your book sales site it generates?

Boy, that didn't go over too well, eh, Mike?

More fodder for the 7th frame, I'd guess....

All you going to do is stonewall when someone asks a legitimate question? You started the thread with remark that makes you look somewhat foolish, and now you are setting out to prove that you are?

Honest, this can't be the real Mike Johnston, can it? You sound even more like Ken Rockwell now.

Ken, is that you???

You're going to judge the performance of a pre-production unit based on a few samples taken under non-controlled conditions? With no basis for comparison (like the same shots taken side by side with a 20D)? With no in-depth testing? Without testing for yourself?

Man, I know you have tons of experience, but I can't agree with this assessment.

yes the images don't exhibit stellar DR, but i'm surprised you with so much experience can't see that's how the photographer chose to expose the scene.. show me a camera (your newly acquired softer-than-a-baby's- bottom-KM7D included) that could do better in those conditions?

I'd never call you a troll.

But it's clear you have a serious "premature evaluation" problem, which you might want to deal with.

What do you expect. You have a few shots, processed in relatively uncontrolled ways, with a beta version of software. It's a bit a quick to turn yourself into a CNN talking head, don't you think?
