DIY Carbon fiber hood for Canon 300/2,8L (non is)

I decided to make new hood for my vintage 300/2,8L from 1988. Original hood was damaged and was not round anymore.

nicely done!

CF is also great for holding optics such as in a lens, very rigid and low coefficient of thermal expansion, so holds all your optics in perfect alignment much better than metal. Getting used more and more in telescopes.

CF is seemingly everywhere these days -- tripods, aircraft propellers, cell phone cases, medical devices that require radiolucency, etc.

One wonders if Canon would use it to make a super-light (but likely very high end) frame/chassis for a camera body -- have they ever tried this before? It would surely be light and rigid, but one wonders about impact strength, cracking, etc. as well as manufacturability (holes/windows in the chassis create stress risers which CF may not tolerate well) For something you'll handle roughly (minor drops, knocking into things, getting bumped around in your bag in the back of a car/truck, etc.), you generally want something more ductile / higher elongation before break, and (for all its virtues) that is one of CF's weaker suits.

CF can be immensely strong, just look at how much less of a death trap F1 cars became when it was introduced. These days when the cars come together they're either unscathed, or broken. You don't get bent bits like you did years ago.

So long a Canon put enough layers in then it should be bomb proof.
