6D gave me really blurry photos?

[Sophós]

Hello everyone.

I'm posting here hoping to find someone who can help me.

I recently got a 6D mark 2 to shoot my videos and it was all fine. Last night I was asked to take some photos during a meeting but I immediatly saw the lack of quality in all of them. I can't explain this absence of details even in the darkest enviroment or with the slowest shutter...

AndreaW, exactly, this "watercolor" effect on out of focus area has never happened to me in any canon cameras with any lenses ive used. This is why i tested all my lenses in all of my other cameras, and the only one that gives this issue is the 6dmkII

Ignacio, I could not have said it any better, thank you!! I am a professional photographer (www.AndreaWattsPhotography.com) and really was hoping for some answers on this Canon 6D Mark II. Instead, I was also treated like I did not understand depth of field. I think it would have been better for those individuals who did not quite understand the issue to withhold their comments. I feel better. 🙂

Dear Ignacio,

OK, your straight out of the camera JPG had default processing applied by the camera itself and that may be where the issue lies in terms of aggressive noise reduction.  I know that you can't retake exactly the same scene but try to set up something similar but shoot it in RAW instead so you can separate out what is being done by the camera default JPG processing parameters.

Default JPG conversion parameters often work well but when faced with a complex image (very shallow DoF coupled with very high dynamic range and significant low light areas) then that is the perfect recipe for processing artifacts to occur.  I still believe that greatly insufficient DoF is the root cause with the dynamic range and dark areas a contributing factor and that was exacerbated by using a default JPG out of the camera.  For some reason, Canon factory setup is for the default output as JPG (even my new 1DX III was set up this way from the factory) but I really think that is a horrible choice.

Direct JPG output is convenient but it throws away too much information and makes too many decisions for the photographer such that I would never trust an important shot to it regardless of manufacturer or camera body.

Have you performed an A-B comparison between the 6D and 6D Mark II with the Sigma 35mm lens?

The Sigma lens has very strong vignetting at f/1.4 that extends well into the frame. See the f/stop comparison in this review:

https://www.the-digital-picture.com/Reviews/Sigma-35mm-f-1.4-EX-DG-HSM-Lens-Review.aspx

Could that be the effect you are seeing, rather than some issue with the camera model?

[IgnacioSottano]

John and Rodger, thanks for replying again.

But unfortunately the answer of both cases is no and no.

John, ive compared the sigma on my 5d mark II and my 6D II, i even compared it to my old 6d, and this ONLY happens with the 6d mark II.

Rodger, again.. jpeg has nothing to do with it, like ive said on the previous posts, ive compared it to my other cameras and this only happened on my 6d mark ii, BOTH in jpg and raw files, ive shot in RAW, RAW + JPG, and JPG alone and this is always the same result.

I know you are trying to be helpful, but i am starting to feel like andrea. Trust us when we say we indeed know what we're talking about, and this is a problem of the camera. 

Its not a vignette issue, its not a jpg issue, and its certainly not a depht of field issue.

The way I see it, you have been asked for exposure settings and failed [to] provide it.  This means  your complaints lack merit. Your opinions are NOT facts.  If you have no facts, then your complaints lack merit.  End of story.

Ignacio, the bottom line is that they don’t know the answer to our issue and for some reason just cannot accept it. I think because it does not make sense to them either. (It’s definitely a weird problem. One that I have never experienced before.)

I would love for Canon to address the issue because we cannot be the only ones who are experiencing this problem with the 6D Mark II.

Just so you know, this is an end user supported forum, not an official Canon support site. You can call Canon at 1-800-OK-CANON and chat with them. Perhaps sending your camera in for service will correct your problem. 

I will try to assist because as an engineer I like to problem solve. 

Can one, or both, of you post a RAW file in a Dropbox or OneDrive folder so I can see the files on my computer?

John,

I appreciate you taking a stab at this. There was a guy who posted this same issue about a year ago and he provided one of his photos.

Unfortunately, I have no picture to post with this issue as an example because I deleted all of the photos that have the bad effects in them. The issue that Ignacio and I are experiencing with the 6D Mark II is that the areas in an image that are out of focus look like a watercolor. In other words, those out of focus areas are beyond out of focus. Sometimes those areas just have a splash of color where you can’t even guess the image. Please understand we are not questioning WHY a particular area is out of focus. We both have a full understanding of depth of field. 🙂 We are questioning why the out of focus area has been reduced to just a blotch of color, hence the “watercolor” appearance.

Exposure information is 1/15 of a second and aperture is 2.8. using a canon 600 ex rt.

But.. i dont think you are seeing what i mean. It doesnt matter if the image is bluried, or the subjets are moving, or is in focus or not, what im talking about is that this camera sometimes in the areas that are out of focus, that non-focus is very oddly rendered. Therefore i gave the example of the guys hair. no out of focus or moved hair looks like that. 

Ive had this problems with photos at 1/100th of a second even in 2.8, even in 4.0, even in 5.6.

But this was never the case on other cameras while using the same lens / settings.

John, i will soon upload a RAW file showing this problem. Tomorrow i have a wedding and i will take the camera as my second body so i can prove what i mean.

Thanks again for taking the time to read
