I Will like better sharpness and Sharper lens for aps c like sigma did with the 18 35 f1.8 . I dont want to pay big price for L when i only use 50 % of it

Just the one in the middle, doesn't really count as 'linked' :)

All AF points can be used for that if you set the correct metering mode, both according to the user manual and my testing. I use it all the time while photographing birds.

gekko, can you tell me where in the Manual this is described for random AF-points?

Have a look in the table at the bottom of page 203.

Thanks for your reply, gekko.

The page you refer to describes 'AE Lock'. I have seen that part when I read the Manual after buying the 80D, but discarded it as of no use for photography of airplanes or other (fast) moving subjects. AE Lock means the exposure is locked to whatever light levels are measures at the moment the "*"-button is pressed and after that does not adapt if light levels change due to changing light levels e.g. as a result of following a bird.

Photographing BIF as you wrote, is even more challenging than aircraft as a result of often faster changes in light levels of the background that changes.

So, can you explain how you use this in your photography?
I am very interested to find out how you achieve this.  :)

P.S.     I do not want to 'hijack' this thread, but there is some relation with the 7D Mk III's features, so I hope it is okay to ask this follow-up question.

Not much to it: use Evaluative Metering + AI Servo and shoot as you normally would. The camera will set the exposure based on the focus points in use. Keeping the shutter button half pressed and tracking your target keeps the exposure updated as the focus points change. No need to use AE Lock.

Thanks again for your swift reply, gekko.
You wrote "No need to use AE Lock". I will surely try this.
I do not understand why the table at page 203 that apparently describes this is called "AE Lock Effects" and why it is in the paragraph called "AE Lock" instead of somewhere under the paragraphs of exposure and/or AF.

Remove the low-pass filter. The 5DSR gives so much sharper images cropped to the same size. That and improved AF would be enough for me to upgrade.

+1 but I'd like a tilty flippy too. Possibly 24MP without the AA filter would be ideal.

Here's a thought experiment about flip screens. How would a flip-out screen fit on the 7DIII, if implemented? I see the challenge not just in the weathersealing/durability as Canon have always claimed, but in the displacement of no less than 5 buttons on the left hand side. They could make the screen up/down tilt only, such as the Nikon D850.

I think they would have to either rearrange the buttons to be more like the 6D (and killing the control continuity with the 5D line) Or they would need to create a VERY thin bezel on the flippy screen, and put the buttons above and below the hinge mechanism on the left. I also see space to move the trash button below the dial.

Biasing the multi zone meter to the active focus point, is not the same thing as spot metering off the active focus point.   What you're describing instructs the multi zone metering algorithm (evaluative in Canon's case) to give extra weight to what you've told it is the subject.   

Spot metering means "give me a reading to make whatever is under this area my neutral gray tone"

Personally I don't get the fascination people have with that feature, but still, not the same.

The only buttons that I use on the left are the zoom, playback and trash button. Having a dedicated rate button, direct print button are just wasted imo, like they needed to fill them with something. Never used them ever, especially when sometimes you rate and bridge or lightroom doesn't pick the rate up. Sometimes just because they have been there for a long time doesnt mean they deserve to be there. They could also be modified to work differently per application so they do one thing in playback and another in shooting.

I wouldnt mind the zoom button being the set or the AF selection point button like it used to be in the older cameras. (while in playback)

I think a tiltable (like the 850) is feasable and sufficient. The camera is too heavy to be a selfy/vlogging camera and the target audience would never use it for this its more down low up high so a 180deg would be fine and a lot easier to implement.

This illustrates the problem with change. I never use the trash button, but I must have a rate button. When shooting sports I often go through the last sequence and quickly mark the images that are possible keepers. During halftime, timeouts or after the game I often scroll through marking shots. Since it's not hard to shoot several thousand frames during a sporting event, it's a huge time saver to have a few shots already selected.

Frankly, while I can see the advantages of a flip screen and I don't believe for a second that durability has anything to do with Canon not putting them on the 7, 5 and 1 series -- just superstition on the part of photographers – I would forgo a tilt screen if it means rearranging the back of the body.

I strongly suspect that Canon has surveyed photographers and found that most pros will say "don't mess with my buttons" as people who use their cameras daily are creatures of habit and don't take kindly to having the cheese moved around.

An articulating screen would mess with left buttons :)

They could make the interface more like the 1 series.

The weatherproof tilt screen excuse is pathetic too, not you, from Canon. In 2014 Olympus made the Olympus Stylus Tough TG-850, it was a budget P&S with a genuinely waterproof, not 'weather resistant' tilt screen. If Olympus can do it in a $300 P&S I'm sure Canon could do it in a $2,000 DSLR.
Too often we lose sight of the fact that photography is about capturing light, if we have the ability to take control of that light then we grow exponentially as photographers. More often than not the image is not about lens speed, sensor size, DR, MP's or AF, it is about the light.

And yet they still do! Mind you, the healthy mouse is the one who goes looking for cheese when it has been moved  ;)

Here is my last camera vs my current camera.

Could very well be that you are correct.
When testing on high contrast targets (light/dark)  and single AF point, panning the focus point from f.ex dark to bright, the exposure does not change until the focus point hits the bright part. Keeping the focus point on the dark side, but close to the bright side, does not change the exposure, so if the exposure is weighted, it is within a very short range from the focus point. To me it seems like the exposure is taken from the focus point itself. It really doesn't matter what you call it, it behaves just like I want it to, giving me the exposure of the active focus point(s). :)

fair point. But if you come think of it:

there is only ONE correct exposure in the scene :) the thing is, the camera measures reflected light from the not necessarily 18% grey surfaces (50% reflectance). Hence the reading your camera gives you is a bunch or semi accurate readings unless you spot meter over grey card and even still - not 100%.
Canon evaluative metering is very good though in general and unless you are willing or have time for taking proper metering, what you are doing is perfectly acceptable in majority of run and gun situations.

Could very well be that you are correct.

For Me:
1. Larger buffer. I shoot Raw and hate to switch to Jpeg to keep up with action.
2. Improved GPS.  Current GPS takes some time to lock in.
3. Removal of AA filter
4. Faster Memory Card support.
5. Tilt screen.
6. Touch Screen
