Sony's superteles are white, too.  I think when you make your lenses white it means "we're really super serious about photos, guys.  Super. Serious."  I'm gonna guess $8k intro price. 

The whiteish colour is not just for good looks. It prevents the lens from thermic expansion (e.g. from prolonged sunlight exposure), which would lead to misaligments in the barrel (even a few microns can make or break it). At least, that's what the Canon has been proclaiming for years...

Reduces thermal expansion, it can't prevent it.

Looks like fake. Front element from 14-24 Nikkor and the rest from 17-40.
Canon will never put a red ring on a hood, it will be on a body, even with integrated hood.

Definitely not a 17-40L body, closer in style to the 8-15L but not the same.  As for Canon never putting a red ring on the hood.

I reset the camera, and tried that, and it still did not work. Then, I just hit the AF mode button (the one on the back, which you press first, before pressing M-Fn to actually switch modes), and moved the joystick. That worked. So, in most AF modes, you can just move the joystick, and the selected AF point moves. But in all points mode, you have to first hit mode, then use the joystick to move the AF point? Seems very tedious...

But, it does seem to work...mostly. It does initially lock onto the subject under my selected point...but it jumps a lot. As I track, it doesn't seem to really STICK to the originally selected subject...which is kind of annoying. I am not using my 600mm lens, though, so maybe it will work better on that.

What are your tracking sensitivity and AF point switch values?

In the text there are bits like this:

Quote
65-point* all cross-type AF system for high-performance, accurate subject tracking with EV -3 sensitivity (center point) for focusing in extreme low-light conditions

I haven't seen anything indicating what the *'s are for?

Me, either.  But I suspect it's a footnote that you don't get 65 points with all lenses.  Similarly, with the 1D X/5DIII's 61 AF points, you get only 47 points with the 800/5.6L and only 33 points with the 180L Macro.
"

May I ask? What's the science and logic behind this??

If the DSLR have 65 points hardware wise, what physical limitations contributed to the reduction of working AF points?

The cross-type sensors need at least an aperture of f/4 to get an accurate measurement.  Not sure why the 180L is so limited though.

my Fuji X-T1 (my travel camera, no good for sport) is much cleaner and usable at all ISO (at least up to 3200).

I thought the same thing until I noticed some strange differences with the X-T1 during my DualISO test.  Basically, the ISO number Fuji shows are complete BS.  Try taking a shot of a grey card or something similar at ISO 3200 for the X-T1 and a Canon or Nikon camera and try to match the histograms.  See how the shutter speeds compare.  I've found that the Fuji pretty consistently requires 2/3-1 stop more shutter speed to get the same exposure.  Also, I'm pretty sure Fuji's doing some pretty heavy handed chroma noise reduction in camera on the RAW files.

But that battery - looks like this beast will need more juice if the battery "only" lasts for 670 shots. More grips sold shortly...


I thought I saw 800 somewhere- might've been B&H's spec comparison to the 7d. Regardless, I got about 2000 on Saturday and only went through half an LP-E6 before swapping it out- that's about 4x as many shots as Canon claims for that battery in the 7d. If that holds true, I won't worry too much about the new battery...

Yeah, Canon's battery life estimates are extremely conservative.  I shot an event yesterday with a gripped 5D3 and after 6,000 shots both batteries still had 70% in the tank.

Also new for the 7D-series are interchangeable focusing screens. The default screen is calibrated to display approximately a f/5.6 depth of field, however for precise manual focusing with f/2.8 lenses or faster, a Super Precision Matte screen is available as an optional accessory that will show the true super-thin depths of field through the viewfinder.

Looks like Canon is bringing back interchangeable focusing screens, nice.

And this from Canon USA:

Oh man, that demonstration of the anti-flicker is awesome.  That feature alone will put Canon head and shoulders above everyone else for indoor sports.

Anti-flicker shooting

The EOS 7D Mark II features a new flicker detection system that not only alerts the user in the viewfinder, but with the camera’s Anti-Flicker Shooting function can compensate for flickering light sources, taking shots only at peak light volume. This feature is useful for minimizing disparities in color and exposure, especially during continuous shooting in sub-optimal lighting situations.</p>


I find this super interesting as this is a huge problem for me when shooting indoor sports in really awful lighting.  I hope to see this feature on the next 5D model.

v The EOS 7D Mark II is compatible with the optional WFT-E7A Version 2 Wireless File Transmitter.

So maybe Canon will release a new wireless transmitter that doesn't suck so much.

I'd lean more towards the camera having a built in radio commander that can act as a wireless trigger than a true wi-fi setup.

I'd lean more towards you needing to buy a WFT-E7 II for each camera on which you want to sync the time.  I know you think I'm probably joking, I wish I could say that I was...

Ugh, I'd really like to think that they'll include at least some basic RT functionality built into the body but you're probably correct.

you know this no wifi thing has got me pondering a bit.  If the rumor is true that multiple 7DII can sync time with each other, it would seem that they have to have some kind of wifi going there to make that happen.  One could assume that a GPS enabled camera could get it's time from the GPS sats and all should be within 50 ms of each other.  However it was specifically mentioned that the cameras can sync time together.  That to me means some kind of wireless communication is going on.  Wifi would be the easiest way to do that with current tech.

I'd lean more towards the camera having a built in radio commander that can act as a wireless trigger than a true wi-fi setup.

c) AF technology form 1DX and dual pixel technology - no efforts from Canon side. They just simply included very good autofocus in this camera. I expected a bit more from them.

It's not the same AF module as on the 1DX/5D3, it's completely new and I'm really hoping it leverages the patent posted a while back that showed the dual pixel AF working in conjuction with the mirror based AF system.  In terms of number of cross type points, this is the most advanced AF system we've ever seen; not fair at all to say no effort from Canon's side.

The children in the design department at Canon do stupid things and this time they did exactly what I feared... they removed the zoom +/- from the right side just like they did in the 5D II... HOW STUPID IS THAT? Having to reach to the other side of the camera to review a picture is pure stupidity when you use the big lenses like 500mm f4 etc. I hope the lever by the joystick is going to do just that.

The question is ... why remove something useful that did not imply extra buttons etc? They should let you chose any function for any button and that would solve the problem in a way.

The other improvement I hope for is the AUTO ISO function with ISO bracketing plus the multiple exposures.

And by the way... a grip with a joystick ... is that too much to ask?

Cheers

Change the set button to zoom and you'll find it works much much better than the old setup ever did.

This new processor is the key to high MP cameras.  Doubling the resolution will require 1.414 times the processing power.  The current Digic 6 will drop the 1Dx to 8FPS.  The Digic 7 is going to be a dual Digic 6 in one package which will allow 4x the processing power for high MP, high frame rate bodies.

That's not true, processing effort will scale linearly with number of pixels.  If you're talking about doubling the linear resolution, then you'd need 4x the processing power.

I love when websites compare the 70D/7D2 against mirrorless and give the advantage to the mirrorless camera because they have "200" AF points on the sensor while forgetting that the 70D/7D2 have 20 million (~16million selectable) AF points on the sensor.
