This is most likely due to the fact that the cameras you are referring to have better coatings, layered glass, or an OLPF layer protecting it. The glasses in your house don't corrode because they lack the blue/green pigment which is sensitive to corroding.
@@kolarivision1674 I am pretty sure the "blue/green pigment" is the IR filter that most camera sensors have. I assure you this is NOT the sensor itself. As far as I know from my chemistry knowledge, silica glass does not corrode under normal circumstances. You need special chemicals like, (strong bases), heated sodium hydroxide or, (strong acid), hydrofluoric acid to begin breaking it down. The most likely explanation is that it is camera models that use a clear adhesive to stick the IR filter onto the sensor rather than, (the smarter), removable retainer. Much like with the adhesive used in lens elements, this adhesive can break down over time due to moisture or bumps and bangs. I have been tinkering with cameras and camera equipment for decades and seen enough IR filters to know.
Looks like both Leica and some Blackmagic cameras use a sensor made from the Belgian company CMOSIS, would they be the ones providing the “Hot Filter”? Do sensors made by Sony and Cannon have this same issue?
Highly informative video on the subject of corrosion. However corrossion is a corrosion and fungus is a fungus. I have to disagree on the "Camera Sensor DOES NOT Have Fungus" statement. Depending on one's geo-location the fungus is a valid and present problem - where I am it's for at least half of the year. Unlike the corrosion, the mildew does not differentiate between materials. It does not matter to a fungus whether it grows on a glass of the lens or the sensor, or other parts of the camera. It will happily eat into whatever surface it can process. If detected early, fungus is easier to deal with and without adverse effects, unless it's been there for long enough for its enzymes to eat away the surface material.
This is mainly due to the color grade and the fact that our subject was surrounded by foliage casting some green onto her skin. It is not apparent with the OEM hot mirror because the infrared spill is overpowering the green spill from the tree. In situations like this you need to add back some magenta into the skin tones for a more balanced look but it is entirely the environment and color grade not the filter.
Oh joy! A completely new worry…
Cool to see an in-depth video on this! I need to finally get my M9 sensor replaced since it went half pink on me ;P
We can help with that!
That topic opened a can of worms for everyone thanks for clarity
Can the new BMCC6K that has OLPF also suffer from this problem?
Nvr heard of this. I have used cameras that were 20 years old and never seen this. Why do the glasses in my house never "corrode"?
Sounds suspiciously like a solution in search of a problem.
@@docandersonshow I have a suspicion that it may actually be more the coating(s) wearing off, or "corroding" than the glass itself.

I've had my Sony A7S III since 7/1/21 and I've never encountered this.
Used canon for 7 years ... din notice this kind of thing
My 2004 Nikon D2X does not show any sign of this issue
I have this Fungus right now. Can i solve it by myself ? tried to clean my sensor with a kit but doesn't work at all

do you have a UV/IR filter insert in housing for the M8/8.2 so should I could shoot through my pre-war lenses not using a lens filter?
Do you have OLPF filter for BM 6K Pro?
So what does SONY use?
Glass is not a "crystalline structure" (0:58). Glass is an amorphous (non-crystalline) solid. You have just lost all credibility.
The upgraded hot mirror one does seem to cut IR pretty effectively but I have to say the skin tones also become very lifeless.

3:40 - Stainless steel can easily rust if exposed to water though.
Stainless steel rusts differently depending on the grade. For example, grade 304 is particularly rustproof because of its high nickel content.
