Hi everyone,

Thinking of shooting things with fire in the photo, the lens would be quite close to it (and maybe even extension tubes will be used).

In here: https://global.canon/en/quality/story/vol02.html, Canon explains why Canon paints their lenses white, is to protect the lenses from heat.

Would like to know if this is a concern.

I read all the responses, and I wouldn't want to have a lens close to the fire.  And even if melting is not going to happen, the gases that come from the flames would not be good for the lens.  I see you have a Sigma 150-600.  Put the extension tube on that lens and get some distance from the flame.
