Question regarding R6 and hot pixels (especially on long exposures)

[arlicht]

Hello.

I recently bought new Canon R6 (mark 1) and I found that on long exposures I see a lot of hot pixels.

I took some photos with lens cap on, for the test purposes. I will share RAW .CR3 files. Could you please check them and tell if its a normal behavior or I need to contact Canon Service for the repair? This is my first ever camera and I am a little bit worried regarding this issue right now. Also if there someone have R6 could you please share your RAW files with long exposures with lens cap on for comparing?

Thanks

That's at ISO 3200 and 30s with LENR off. I got my Canon R6 mk1 just before Christmas

Thanks for sharing! 👍😀

This is not something unique to cameras.  It affects the automotive industry, TV's, CPU's, processors and more.  

If the camera is a week old, it should still be returnable / exchangeable if you procured from a reputable seller.  The next one could be better or worse I suppose.  I'd get it addressed if it bothers you.

BTW, nice catch. Muon particle, I suppose.

I am real newbie in photography and I respect and am thankful for your replies guys! And I am sorry if my questions are kinda dumb for mature professionals. After inspection of Peters R6 raws I understand that other cameras have similar or a little bit less or more of those Hot Pixels. 

My next question is - will those hot pixels increase over time or the CMOS sensor degrade? 

And what you think guys - do I really need to send my R6 to Canon Service for warranty repair or I need to forget about this issue and more focus on learning photography art and enjoing my camera as it is? I was worried about if my new camera have ''NORMAL'' amount of those hot pixels or it has them too many for new R6 camera and I need to service it? I am not worried about that they are there, just about amount and if its adequate for new camera or not.

They will not decrease, but Canon sensor mapping will hide most of them for you.

Other makers remove more bad pixels already in camera, just like you will see with your R6 at ISO 12800 and above.

And no, I don't think you will need to send your R6 to Canon Service. Will you ever have a problem with bad pixels? If you see them in daylight you perform a sensor cleaning or remove them in your software in post with just one click.

If you shoot astro you will use a dark frame anyway.

I suppose that most of the bad pixels you see at 30 seconds work flawless at 1/200 sec?
