Magnesium does not bend well, but crachks pretty easily,. Odds are that it would have cracked.

well i feel like the bend is what caused the crack...basically that little pin was pushing out, and pushed it enough to crack it

That would take a revolutionary advancement, not just evolutionary, to get the same ISO noise level as pixels 2.5 times bigger.

It would be a revolution to get the same ISO noise level as a *sensor* 2.5 x bigger in area. Pixel size doesn't have anything to do with it. ;p

When you have small objects, you are limited to supporting small forces.

So for a battery door, Canon needs to supply spare parts. Magnesium or plastic - the tiny amount of material around the hinge or lock will be very sensitive to accidents. Best is if the design can have some body material sticking out like a crash shield and protect the sensitive areas of the door.

Here is a long debate about plastics or metal - and a number of photos of cracked magnesium bodies.

Seems there is a new variant of the LP-E6 battery only for the 7D2, any idea if the original E6 will work?

Yah. Honestly the way Canon and Nikon do it is quite good. Metal or CF frame w/plastic body surrounding it. If things become more and more flexible and resilient (things like LCDs or OLEDs) we might eventually have the sensor box and mount being a metal body with the rest of the camera being a softer plastic. The sensor and mount must be stiff with regards to each other, yet strong, so they remain aligned perfectly. It's not desirable imho to have the shell and even all of the frame always be metal. An impact on the back or sides of the camera should absorb and dissipate with material giving way and bending but springing back unharmed. While protecting the things that matter inside from becoming damaged. One thing is, there are a ton of different types of plastics. High quality strong ones can be amazing. But there's some really cheap plastic crap, too. I haven't heard of 100mm L's breaking, that's for sure.

You are bickering over spilled milk and guessing what might have been. Not dropping any fine instrument device if of utmost importance. And what might break on a fall very much depends on which point of the device hits first. Your lens taking the blow on a drop might cause problems for lens, lens mount while the corner of the bottom of the camera hits first and everything will probably be fine.

Initial previews I've seen (like Matt Granger's preview), says that the E6 will work.

As far as I know, this is incorrect. Pixel size does matter. Full frame cameras with super high megapixel counts struggle a little more with noise than more moderate megapixel counts (assuming same generation technology).

If I don't get the shots I want with the gear I have, the only optics I need to examine is the mirror on the bathroom wall. The root cause will be there.

It is indeed directed at those a bit more 'pro', which also includes the ff shooters. The rebel line is targeted at those users moving out of bridge and p&s cameras, the 70d is for the next level, and the 7d for those that want something more akin to the 1d series, or a crop backup to their serious ff work. Remember the 7d is the 3rd level aps-c body, both in feature/function and price. Mom and dads just getting a camera to shoot little johnny slugging a ball are not typically out spending $2000 on a camera kit.

6d + 70d
Or
5d3 +7dii

Canon would love to have every ff shooter adding an apsc to their bags! They would also love to entice all those that currently shoot with a 70d to upgrade. A 70d and 70-200 II are more than sufficient for shooting the moon, highschool football, and swimsuits, but for those that either know they need more OR think a new body like the 7dii will improve their results, Canon wants them to believe they need to upgrade. ;)

So those that buy the 7dii:
o those that change gear every year or so due to wanting the latest and greatest
o those with larger pocketbooks
o those that are hindered by their current gear
o those wanting a good backup to their ff gear
o those that cannot rationalize or have the funds for a 1d series
o those with really old equipment and think it's about time to upgrade and don't want to upgrade again for several more years
o those that aren't sure why their current apsc body isn't producing the results they want

Are a majority of these folks a mom or dad? Yes...

TeamSpeed,
I think you’re spot on. I started with a t3i, then a 6D, the combination worked well for me. Taking photos of food and my grandson’s playing at the park. Spring came, my grandson’ s T-Ball games that I enjoyed capturing those special moments. Trying to capture that moment when the bat hits the ball, never happen, no matter how hard I tried. I replaced the cheap SD cards purchased online, with SanDisk Extreme Pro’s, I saw improvement in the 6D, I sold the t3i. :) As much as I loved my 6D, it just seemed to be a bit slow on speed. I saved and bought a 5D MK III, in my opinion the best affordable camera ever made at least to me. After his T-Ball season ended, I sold my 6D, I got lost in the HYPE of the GH4 and soon realized it’s just wasn’t for me. There is a new camera that I’m hoping for, it's the Canon 7D MK II and I can’t wait to see all of the Hands On Reviews, not infomercials that you see now. I’m hoping it will be a nice companion to my 5D MK III.

ha...i'm not bickering over anything...all i'm saying is in my mind...i feel like a magnesium body would've probably held up better than my 70D

do i know that for certain? no...but it doesn't mean i can't think that

This might easily start a new wild sub-topic debate. But you do not need a magnesium body to get a rugged camera. It's great to have an inner chassi of magnesium since it is good at keeping a fixed shape and keep all critical components at fixed distances from each other. But with an outside shell in magnesium, the body will shatter - or the components will fail from huge G forces - for impacts where a plastic outside shell would nicely dampen the impact and the plastic would then retake the original shape.

All-magnesium is something the manufacturers do because of psychology. They have too many customers that demands magnesium because they think that's best for them.

I would also think that a magnesium body also helps to dissipate heat better than plastic.

I did a search on 28 and nothing came up but I noticed on Amazon's web page for the 7DM2 that the release date changed from November 17 to November 28.
