Next E-M1 MK II ---- Carbon Fibre?

I would prefer to see the next E-M1 MK II as a Carbon fibre model instead of full metal body. MUCH stronger than metal plus shave off a LOT of weight. Thoughts?

Think the E-M1 needs some weight shaved off?!? REALLY!?! Have a go at lugging a D4 or D800 with a lens or two and you'll change your position - literally and figuratively!

Stronger but more brittle. I would rather have a dent than a shatter.
Perhaps plastic is more brittle or easy to break but not carbon fibre, unless you drop your camera to the floor which will ruin it either way sensor misaligned, shock in electronic components etc.
As far as comparing it to a FF with lens... blah blah I used to have a 5D III know what thats like, but hey you always have to improve and keep moving forward even with newer materials. Otherwise ..... another one bites the dust aka Canikon

My understanding of CF is that it has electrical properties that make it poorly suited for such an application. I don't know whether this is in regards to conductivity, shielding, etc...

CF has very interessant structural properties, but other than looking cool I'm not sure it would do much other than add manufacturing cost.

Carbon fibre is not stronger than metal, it's just stronger than metal *for its weight*. It's a very stiff material, slightly brittle (depends on the epoxy formulation, etc), and has been used for electronics (Lenovo's think pads) so it can certainly be done.

It is more brittle than a good plastic, which is probably the most shock proof material, selected appropriately. For a camera that's already as light as an E-M1, I'm not sure more weight reduction is necessarily a good thing; you need some mass to prevent shutter shock (see the A7r issues - though I haven't seen it).

I love CF as a material in my road bike (stiff, light, smoother ride than aluminum and almost as comfy as steel) and use it quite a bit as a structural element in my guitars (neck reinforcement, braces on acoustics), but I don't see an immediate advantage for a camera body or lens.

The issues with carbon fibre are not just the cost vs other materials, it's the fact that it will need reinforcing materials added so that you can install mounts (you don't just screw into the carbon fibre), seals (these require complex and often very fine grooves and the like) and many other considerations when talking about complex structures, which then increases the complexity and cost of manufacture.

Does anyone really think that you could make anything like this entirely from carbon fibre and for it not to be expensive:

Carbon Fibre comes into it's element in larger, very high density applications.

I've used CF guitars and basses and taken a few apart and can't imagine something as hollow as a camera body working well.

For instance, guitars made of CF can actually sometimes be heavier than their wood cousins because of the sheer amount of laminating required to prevent the entire structure from shattering on impact (especially the guitar neck.) CF also has weird resonant properties. Something the size of a camera made entirely out of CF would "gong" when the shutter trips without weight added.

CF is extremely expensive to work with too and I think it's more toxic than Ebony dust when being shaped.

Hmmm... a camera made out of Ebony - not counting drop-bed style large format would be interesting - but Ebony is getting very hard to source ... Ironwood camera perhaps? ;-)

You know, when I get my CNC machine up and running I may just design a wood body for my GF2. Just for laughs. Bubinga with brass fitting or something (since I have a lot of bubinga. And ebony is a pain to actually work with..)

If you ever get around to trying that I'd like to see it... Bubinga is like Pau Ferro - The fingerboard on one of my basses is bubinga and it's very hard. Fodera in New York is using a product called "Diamond Wood" for one their fingerboards. It's pressed wood in laminates with glue. Looks kinda like rosewood, "feels" like rosewood to the fingers. It doesn't have that weird slippery feeling that phenolic resin tends to have.

...Reminds me of the guy who showed up to our studio with a hand-built rosewood telecaster... I asked him where he got all that rosewood... he put his finger to his mouth and shushed me. ;-)

And that reminds me of a friend who used to hang out on different second hand stores. just to buy mahogny furniture and then he smashed them and tried to sell it as bulk. Funny guy
