Eos7D mk2, How disappointed will you be if . . .?

I think that from that statement you are confusing light intensity with quantity of light. So a large aperture ( greater intensity) coupled with a larger sensor ( greater quantity) is going to provide more light than the equivalent in a smaller sensor.

No I actually dont think they do have the b.lls for something like that. If anything the past has shown us that they are arch conservative...their one highlight might have been the leap from 12 to 22 mp with the 5D2..since then they have not ventured into any unfamiliar territory... which has not been a bad thing from their financial point of view but a bit of a let down for camera enthusiasts...think Fuji X100s, Sony Rx100mk3, Olympus OMD, Nikon DF, Sony A7R...the list goes on and on. But if you look at their financials they do seem to still be profitable in the face of dwindling camera sales....

a smaller sensor can be as good as a bigger one when you give him more light... i can agree to that.
but... maybe it´s my bad english but i don´t get what you say.
What matters for final image quality (aside from sensor performance, processing, etc.) is the total light accumulated during the exposure. f-stop controls light intensity (illuminance), not total light. f-stop * sensor area is thus total light, and aperture (not f-stop) controls that. A larger sensor will do better in lower light at the same f-stop because of the larger aperture and focal length needed to frame the same subject the same way at the same f-stop.

Most developments are evolutionary rather than revolutionary, so we shouldn't expect things to change too much at one step.
Look at the original 5D and compare against the MK III significantly different, but II to III not so different. We then should check the MK V against the MK III when it is launched in 2020?.
I think the crop sensor is a good way of trying new technologies, before putting them into FF, simply on cost, so we may see something in the 7D MKII we were not expecting.
I am waiting for the sensors to step up to 16 bit, so we can get 14-15 stop DR.

My disappointment would be about the same as if the guy living next door woke up one morning and had to take a cold shower.
My shower is still warm and comfy.

mhm.. but isn´t some light "wasted" when you attach a lens made for fullframe to a crop camera?
i mean a crop camera use only a part of the image circle.. not?
maybe more light is collected by the bigger aperture, but is all of it projected onto the smaller sensor?

My experience was that from 5D to MK II not so different but MK II to MK III significantly different.
Do other peoples experience match colinrb or mine?

I know this is going off thread, but it is an interesting question because it really depends on where your priorities lie. The 5DII offered a significant improvement in tonal quality over the original, especially in more extreme lighting conditions, a noticeable increase in resolution and a moderately better higher ISO performance. OOC jpegs can be quite useable. The II also had the much improved screen, video capability etc.. The 5DIII gives a very subtle improvement in tonal quality over the II, but a huge improvement in high ISO performance. It is also much faster, has an improved level of build, and of course, the AF in in a different league.
If you look at the overall package of the camera, I would say on balance that each mark was an equal jump forward in 'overall' performance.
I think most would agree that the first incarnation of the ubiquitous 18mp sensor in the 7D was the worst, so hopefully if the 7DII does have a new sensor it will be more thoroughly sorted than the original.

Will be slightly disappointed if it is significantly better than my 70D. I expect it to have better build and weather sealing but hoping everything else just marginal Don't want/need an upgrade this soon

Im pleased with my 7D. I would hope the mk 2 to be a bit better than the 70D. For a while now I have been shooting with my 5D Mk III, but its nice to have the crop factor on the 400mm 5.6. This weekend I went out and shot some birds and the IQ from the 7D still impressed me.

Mixed feelings, but overall a plus to shorten R&D.
To me, Canon leap-frogged everybody back in 2008-2009 with the 5d2 and 7d. Sony leap-frogged back with their sensors in f.f. and APS-C several years ago. I've been disappointed at the length of time that has elapsed with Canon not accomplishing a suitable leap-frog in their sensor technology.
Well, there was the 70d follow focus, but I'm barely interested in video. That was a ho-hum. The 5d3 is a very nice camera with great AF, but sensor-wise was a big disappointment, and very expensive.

Interesting observation. I was disappointed by the 5d3, but a much better AF over the admittedly marginal AF of the 5d2 wasn't a priority. I was hoping the 5d3 sensor could match the impressive Nikon D800(e) that was announced at about the same time.
Not my understanding. I recall that DPR beat up on the prior Canon 50d, and noted that the megapixel race should be over ... the 15 mpx 50d had inferior per-pixel performance over lower mpx Canons. Then the 7d with 18 mpx came out with per-pixel IQ better than the 50d, much to the surprise of DPR (and others).

The 7D was my wife´s camera. I sold it earlier this year, because I thought the 7DII would be released prior to our summer vacation (how wrong was that ...). I have few options but to buy it, since my wife is a bit upset that I sold her old body and she really likes the flexibility of the super-zooms (18-200 alternatives).
I hope it will be a nice complement to my 1DX for wildlife and not just a backup. A near 5DIII/1DX AF system, decent fps, 1.6x crop, 24MPish sensor, some low ISO improvements and hopefully also some improvements in DR. I could´t care less about video, but I´m sure I´ll get plenty.
I have a feeling Canon has made a bit more out of the sensor this time, but it might be that I´ll be disappointed.

Ouch, you'd better hope your wife never reads this, Eldar. If she does, make it very, very clear you meant you sold her camera.
On the other hand, I'm sure she'd be very happy if I managed to sell her old body and get her a new one. A Gisele Bündchen model would probably be well received ...
