Seems like some of you can reproduce this problem at will.  You should report it to Canon as it seems others have noticed it.  I for one have not so it's either some combo of firmware settings or an issue with hardware.  The hardest issue to fix is one that's intermittent.  If this is reproducible you should let Canon know so they can try to resolve it for everyone.

The only times I've seen this happen is when 1) my battery door was not closed completely and 2) with the battery grip installed the twist lock for the battery tray had twisted ever so slightly.  There are switches on both that will prevent a power up. 

Other than that I have shot thousands of hours with the 5D3 and never has something happened like that that couldn't be explained.

Color looks fine.  Its very warm toned likely due to sun angle but I wouldnt call that bad color.  I often find the jpg recompression on these forums are not all that great. 

I just posted the image Great Horned Owl...anyone viewing this, can you tell me if the colours are off? It looks fine on my computer and on my ipad photos folder, but when viewed online on my ipad, they colours are  awful?

Thanks

Better act quick.  Stock is drying up.  Adorama is already out of stock and last I checked B&H only had the zoom kit left.

I can feel my reaction changing from "resistance" to "black or white?" and "22mm STM or 18-15mm?"

I think under the best of conditions you only get a little more than 200-250 shots per charge.  It will be interesting to find out how an 85L or one of the big teles drain the battery in real life.  Need to buy another 200.00 in batteries Neuro.

...the M and an EF adapter without IS?  Using the adapter, does anyone know if the unit then becomes manual focus only (which I'd think would be a challenge without a viewfinder)?   

With the EF mount adapter, an EF or EF-S lens is fully functional on the EOS M - that includes AF and IS (assuming the lens has IS, of course).

OTOH, I imagine AF'ing a lens like my 85L II will suck the life right out of that little battery...

But you can try to sue Canon if you want...maybe spend that hundred bucks on a shyster who'll be happy to part you from your money.  I'm sure Canon would get a nice chuckle from the effort...   ::)

Canon already gets all of my money so none left to hire a lawyer!  ;)

It's not an argument.  I am right and he is blind!  ;)  Just kidding.  It's good to banter things around.  Neuro and I differ on a lot of different topics here.  Neuro has a lot of experience as well as I.  People see things differently as we do in this case.  Regardless and for whatever reason I find the RAW images are better with HINR off even at lower ISO.  There are many reasons to use them and many more to just leave them off and do your clean up in post.

Re 60D vs 7D I did not find much difference in noise between the two but I did not own both at the same time and could not compare side by side.

Someone here must be new, arguing with Neuro Bahaha. Everything I have read agrees with Neuro.

as far as the original topic here, when you import a raw into lightroom it does not apply the standard "canon" noise reduction, but a much lower amount of NR. RAW images look like crap in lightroom untill some NR is applied.

Neuro, I have a Question:
I have noticed the Jpeg 7D images are much noisier than my 60D images, But I assume that is because of more modern NR being applied with the 60D, and the raw files should be identical in quality, being the same sensor, am I right?

443
True.  ACR for CS5 is no longer being supported.  You have to go to CS6 or use the forsaken Lightroom 5 (not sure if 4 supports it or not)

Is EOS-M RAW still not supported by Photoshop/ACR versions earlier than PS 6.0? 
I'm still on CS5.

As I stated give it a try or ask Canon.  That might get to the bottom of it.  What you quoted is that 3rd party software will ignore the setting.  It doesn't state that the camera has not already monkeyed with your image.  That is a carefully worded quote including the part about "most" software.

Regarding HTP, yes it does bring up the noise by about one stop...and in some cases it's better to go the other way and overexpose with a higher ISO to push the noise down by a stop or two in post.

In the case of this aircraft I would have over exposed the aircraft by a 1 or 1.5 stop (depending on full sun or overcast) and blown out the sky then pulled the aircraft back down with DPP or ACR.  The sky in this image appears too dark.  Could very well be HTP was on and was trying to appease the highlights.  Would also be nice to see the metadata tagged to the image as reported by DPP.

As far as HTP and HINR is concerned, I am the source and now turn both off due to the effects it produces on RAW images.  There are a couple of options in the FW that affect raw images and those are two if them.

In that case, I'd like to respectfully ask 'the source' for some evidence.  I believe that the only in-camera setting that affects the RAW image data is long exposure NR, since the dark frame is subtracted before the RAW data are written. 

FYI, 'the real source' (aka Canon) disagrees with you, and states that while some Canon software will try to replicate the effects of in-camera HINR (but DPP, not so much), "Virtually all third-party RAW file software programs, such as Adobe’s Camera Raw™ software, will ignore in-camera settings such as High ISO Noise Reduction....Don’t expect the High ISO Noise Reduction you may have set in-camera to have any effect with most third-party software programs."

As for HTP, that also doesn't affect the RAW image data directly, although I suppose you can reasonably say it does, since you're getting a RAW exposure that's a stop underexposed relative to the ISO you picked.  Like HINR, it also sets a flag in the metadata, but HTP also 'lies' in the metadata, recording ISO that's one stop higher than was actually used to expose the shot.  For example, if you set ISO 400 with HTP, the camera really exposes at ISO 200, but records ISO 400 in the metadata and then applies a tone curve to the JPG file to boost the shadows by a stop - that underexposure is how it preserves highlights (and of course, you also get an extra stop of shadow noise as a consequence).  Most RAW converters recognize the flag, and try to duplicate Canon's HTP tone curve with their own version (DPP uses Canon's version, obviously, but unlike HINR, 3rd party converters don't just ignore the metadata flag).  RAW apps like rawnalyze just show you the 1-stop underexposed file.  Point is, IMO rather than setting HTP, you're better off just exposing to preserve the highlights yourself, then boosting shadows in post yourself, where you have more control over the process.

I find it interesting that this lens being made specifically for the M is still marketed with a FF focal length.  This lens cant be used on any other camera so why did they decide to spec 22mm f/2?  This is not really what you get with the camera in use.

Sounds like maybe grounds for a class action law suit.  I got 100 bucks back from John Deere because they underspec'd the engine on my lawn tractor!

So does the M with the 22mm f2 depth of field behave like a f2 lens? Or is it still like all crops and less shallow?

It's an APS-C sensor - so the 22mm f/2 is equivalent to a 35mm f/3.2 lens on FF.

I dont have any examples.  I turned it off long ago but feel free to try it.  It's more apparent as the ISO goes up but still visible down to 200.  These two filters are used as the image is read from the chip not in post in camera JPG processing like the other filters.

So back to THIS image.  In addition to the JPG artifacts, I also see some color and some banding but hard to say if that was on the original image or due to LR screen shot and resizing for upload.  Really need to see the RAW or at LEAST an uncompressed JPG conversion.  I'm also thinking that this camera may have overheated as that can also introduce a lot of noise esp color blotching and banding.  Usually the camera flashes an error message though when it gets to that point but the effects may be gradual as the temp increases..not just a sudden introduction of noise.

Sometimes the HINR can introduce noise even when not shooting high ISO....even in RAW mode.

HINR shouldn't affect the RAW file - you're saying it does?  Can you show examples?

But the image provided is a JPG and has been processed.  It is obvious when you magnify the JPG file and see the blocking from JPG compression. 

As far as HTP and HINR is concerned, I am the source and now turn both off due to the effects it produces on RAW images.  There are a couple of options in the FW that affect raw images and those are two if them.

It looks like JPG compression noise..maybe either in camera or was adjusted again using software?

it´s an raw image she is talking about.. see the screenshot.

it does not affect RAW at all when we trust the manual.
and i never heard about this option affecting RAW... you have a source?

I would have forgotten the car and just bought a 2nd 1DX.  ;)

the cost of the car was the same as the price of the 1DX . . .

I typically shoot in RAW mode only and turn off Highlight tone priority and high ISO noise reduction.  Sometimes the HINR can introduce noise even when not shooting high ISO....even in RAW mode.

Also, you can overexpose the sky quite a bit and pull the exposure back down with software like lightroom.  That also can reduce noise.  However I have not seen this kind of noise on any of my canon bodies including my old T2i.

Yawn~~~  Might be ok if you are looking to buy a powershot.
