Rebel T6I Sky Banding?

[ElectricMuppet]

Hello!

I bought a Canon Rebel T6I a few months ago and I just took it outside for a spin. I've noticed in all of my photos outside I have these weird bars. I have no idea why. I figured maybe it could've been the weather since it's been horrendously cold lately, but today I went out to test if it was the bad weather and took a photograph instantly and it's still there.  I came here hoping that people who know photography would be able to tell me what this is and what may be causing it? It seems to only happen in they sky of my photos. I've taken indoor photos and they don't seem to be appearent. I have edited these in Lightroom and cropped them in Photoshop so they're more visable. The second image I edited it heavly to show it incase if its not all the visible in the first image. The second image it was snowing when I took it. Sorry for the black mess in it. is it noise banding? I've been feverishly looking online for information but alas I have not been able to find anything that seems close to my issue. 

Sorry if something like this has been asked before. I am truely desperate to find out what's going on. I hope its something that I can prevent from happening and not my camera. 

I shot these with a Rokinon 14 mm lens if that helps. Thank you's any information would be truley grateful.

I can see it at %100 zoom in  chrome and windows deault image view thing as well. Video will be up soon.

Triple posting woo!

The video made it a tad bit harder to see the banding to the naked eye unedited. The bit rate ate it but sure enough I can see a hint of it at the beggining. it become obviously much more noticeable once I edit the contrast to the extreme. then to mildly. click on the actual video and view it at fullscreen 1920X1080 P

I'm glad you're finding this humorus. I on the other hand do not. If you have nothing worthwhile that tributes to the discussion please don't comment. I spent a lot of money on this and this is a serious matter for me.

At 400% zoom, don't waste your time.  You need to show it Canon Service, not these forums.

Canon service doesn't care as they are concerened my camera is fine. I'm still gonna do it

Well, you need a second opinion.  You don't want mine, however.  Good luck, though.

I do want your opinon. I'm just getting stuff together to show that I do infact have a problem so I can get information  how to properly deal with this. Why would I waste my time here if I didn't want others opinons. I would reckon a videos better proof than a photograph with writing over it. That's why I made one.  

All and all this banter is not getting me any closer to fixing my issue.

The video didn´t really show the problem. The raw files you sent me on the other hand were really bad and the issue is visible.

Send Canon service centre a new email, attach the worst raw files you can find.

As a temporary solution I think a flat field correction could help you. Search for Flat field rawtherapee manual, download the manual and check page 71.Search for flat field rawpedia to get the tutorial of how you take a flat field image.

I think Lightroom has a plugin for Flat field, but somebody who uses softwares from Adobe may be better to answer that question.

I have already given you my opinion.  Send Canon sample files, but you seem to have ignored that advice.  You do not need to prove anything to forum participants.  You need to convince your Canon service center.  

Now I see that Peter has given you the same advice.  Send a sample to Canon.  I say buy a small memory card.  Take some shots in RAW format that show the issue, so that Canon can read the EXIF data and actually SEE which camera produced the images.

Do not copy files onto a memory card, and leave it inside the camera.  That does not work, and it will look like you are trying fudge the data.  Take some new shots that reproduce the issues, but leave the card in the camera when you send it in.

And a repeat of a third "opinion"!

""You have a repair warranty."

Exactly.  Where did you actually send it?"    <----Deal with that faculity.

"Call them and explain the problem. Remember honey works better than sour grapes.  They may pay the return shipping."

BTW, I could see nothing in your video.  I would not use it as proof.
