I figure someone is going to ask for examples. Here are a couple taken yesterday, straight out of the camera except for resizing (using the Zeiss 21mm).

I am having the same problem.


Not only with evaluative metering. But with spot metering as well.

I've been doing some preliminary testing with my new 1D X. For the most part, the camera seems to be functioning properly. However, when shooting in Av mode with evaluative metering (I haven't yet tried the other metering modes), I'm consistently getting underexposed images...like a full stop underexposed. I can flip over to M mode and use the sunny 16 rule and get a nice bell curve histogram, but evaluative metering in Av mode isn't giving me the results I expect. I'm still assuming it's pilot error until I can prove otherwise. It seemed really bad when I used the Zeiss 21 with severe vignetting in addition to the underexposure. In fact, it looked like I had shot at night with a flash on the camera. I'm wondering what's going on and if anyone has suggestions of things to try. Thanks.

Anyone test out shadow recovery yet? :)

You might want to make sure that "Lens Peripheral Illumination" is enabled. It should be enabled by default but if not, it will give you a vignetted look similar to how your example image looks.

First chance this week to get out with the 1D X.

Same here. I just bump exposure compensation up a tad and deal. But every raw I pull into PS shows 2/3-1 stop underexposed.

And that doesn't seem like a slight problem for a $6800 camera? Well, I've been doing more methodical experimentation today, and I'm not seeing the same results as yesterday, and I have no explanation. I'm seeing better, more consistent results today with the 3 lenses I'm testing with. In manual mode, I find the shutter speed and f-stop and ISO that gives me the correct exposure. Then I'm switching to Av mode, setting the same aperture and ISO, and see what the camera chooses for shutter speed..and compare the histograms. It's actually behaving the way it should. Slight variations are expected, and the different metering modes are also doing what they should. I double-checked lens peripheral illumination and CA settings, and both are enabled. However, the camera has no data for the Zeiss 21mm, and that might be part of the problem. Although today, I'm not seeing the same thing. ACR has lens data for the Zeiss, and I applied that to see how it did the adjustments. Anyway, back to more experimenting! Seems very odd that I'm seeing different results today.

The 1DX box has been sitting here, still in its packaging, in the office for the week. I have had to move it once or twice this week and the thing that immediately struck me was the noticeable weight of the box. I believe it is 5.5oz heavier than the 1D Mk4, which I have been using for a couple of years now. So the following comments are a first impression of the 1DX, in comparison to the 1D Mk4.

The surface of the camera is noticeably different to the touch from my present 1d Mk4. The 1DX definitely under exposes constantly. One of the main issues already talked about is the lack of the red illumination auto focus points. It is quite different to get used to. A little AF symbol does come on in the bottom right hand corner when focus lock is achieved. However, I moved the camera’s focus up and down the heron’s head to see if the AF symbol would go off, and the AF symbol remained on, but there was clearly lack of focus on some parts of the heron’s head. However, the auto focus system is blisteringly fast and the quality and resolution is excellent. One thing that is clearly different from the ID Mk 4 is the burst rate. With a motor driving the mirror up and a second motor driving the mirror back down, you do not notice the burst passing. It is very silent compared with the 1D Mk4. It is not until the final few images of the burst and the shutter is released do you notice the little noise of it resetting itself.

I will take a run out to Eagle Heights this week and give it a go with much faster birds in flight. So at the moment the jury is still out between the 1DX and my old 1D Mk 4 which it is supposed to be replacing.

Yeah I use exposure compensation as well

Just don't get it. What is with the metering system of 1dx.

Exactly. It's a slight problem.

The workaround is trivial and the issue can/will be fixed with a firmware update. Per your post it may not even be a consistent issue - although that would be harder to deal with... :P

Frankly, I expected worse being a bleeding edge early adopter. The camera hasn't locked up, it's taking amazing pictures, auto focus is better than I expected, ISO performance is astounding, dynamic range is impressive and so on.

I haven't even started tapping some of the more esoteric features yet. I haven't done anything with auto-ISO, HDR (in camera or otherwise) or any of the multiple exposure stuff. I haven't done MA for any of my glass (don't think I need to) and I haven't really tweaked any of the configuration other than setting up back button focus.

Heck, I'm only about 1/3 of the way through the manual!

There are probably a few other glitches tucked away in there somewhere. My 5D2 is on firmware version 2.1.1. The 1Dx on 1.0.2.

BTW, the camera does support AE and FE microadjustment. Not sure I wan to play with that right now... :)

I'm a little confused by the post about the size of the 1D X compared to the 1D4. I had them side by side, and I swear the 1D4 seems larger and heavier. Anyway, no big difference in the feel for me. The focus point illumination thing is a little odd. I think I prefer the 1D4 in that regard. I tested all my lenses with a focus test chart, and I didn't find any MA necessary. Even the psychotic 50L seemed to be on the money. For now, I'll leave MA disabled until I find a lens that seems to need it. Nice that the 1D X allows you to set the MA at both ends of a zoom lens. I like that.

I want to add that I really haven't found anything else wrong with the camera except for the exposure issue, and I agree that it appears to be something that could be corrected with a firmware update. So I'm not particularly worried as long as everything else seems work. I'm running it through the ringer because I have an upcoming paid shoot that's a big deal for me, and while I'll have the 1D4 as a backup, I still want to feel confident with the 1D X.

You seem to making an assumption that the camera shipped with a flaky metering system. I think the wise thing to do would be to wait until people have some experience under their belt with this body and then if they have issues with it they should contact Canon. I can say that I have given mine a slight workout and am not getting the same problems that are being posted.

I never took a shot with the camera before I had gone through the menus and got my settings to the way I like them. The defaults have never been my way of shooting but each person has to set these to what works for them.


My life is like one big RAW file....way too much post processing needed.

Similar complaints about metering when the 5D3 was released.

Yes, more than likely a simple firmware fix, possibly not. sdipirro got different results, same conditions, from one day to the next. This gets my attention.
