Are These The EOS 7D Mark II Specifications?

...I will hold off on upgrading until Canon gets a clue, or make the switch to Panasonic, perhaps Sony, (who do appear to have a clue).

A clue about your specific needs, that is. I wonder if Panasonic or Sony have a clue about how to make products that appeal to the majority.

For those who addressed my question on on-sensor ADC, thanks. Concerning heat dissipation, why not a Peltier unit affixed to the sensor assembly?

Sth. around 3 Amps @ 5 Volts means 15 Watts of power consumption for the peltier element* + a fan to remove heat from the hot side of the peltier element.

A LP-E6 (if 1800 mAh and 7.6 Volts are correct) would run the peltier element for nearly 1 hour without the camera!

Sorry, but that is the cruel thing with physics ...

* added later for better readability

FWIW, several of my scientific cameras use Peltier cooling in sealed units. This Peltier-cooled Zeiss camera draws 5 W max (via a FireWire bus).

What is the sensor size of your camera? If its sensor size is 2/3" like the AxioCam HRc than its just roughly 1/16 of the sensor area of a 35mm (FF) sensor and I think 15W for FF is consistent.

Power demand for the peltier should be proportional to the surface of the chip (which should equal to the amount waste heat produced by that sensor), if the same sensor technology is used.

Another problem is that microscopic and astronomy cameras are often operated in climatized environments - cooling down a camera chip means to work against 35 or 40 degree celsius envirenmental temperature which increases power demand exponentially.

Yes, small sensor (2/3", IIRC - ~6 micron pixels). With translation of the sensor, it achieves 12 MP resolution – static subjects come in handy, and that trick works because there aren't microlenses.

Maybe not. I was interested in upgrading my current camera, but 4K video (or lack thereof) is a deal breaker for me. My current equipment works just fine for stills, so I don't see the need for significant upgrades there. I don't need 10 fps when I rarely take more than 3 frames at a time. 200 (or whatever) focus points? - who cares when you only use one. What will make a difference to me is having both my still and video needs in one camera, and having the flexibility offered by touch screen composition.

If the new 7D only has HD video then I will hold off on upgrading until Canon gets a clue, or make the switch to Panasonic, perhaps Sony, (who do appear to have a clue).

If you already have a camera for stills and need a serious performer for 4k you would be crazy not to go GH4. I used one recently and i am not a fan at all of 4thirds but the GH4 is amazing even in 1080p. Makes the 5D3 look soft every time you compare (and i hold the 5d3 and 800 in high respect for video). The still are not bad if you don't do much cropping and you have sometime to learn the tricks of using it and getting the best shots.

My 7D has served me well having been to 7 Continents including 4 trips to Africa, 2 to Antarctica and 1 to Siberia. I shoot mainly wildlife and birds with only secondary landscape/travel and artsy/fartsy stuff and have generally been well served by this camera. After my last trip to Africa in May I had to send it in to Canon for focusing issues and the mirror box assembly had to be replaced but they reported 260,000 clicks on it, so I've definitely gotten my money's worth! Wish it could have lasted until the 7DMII becomes available. I'll definitely appreciate more accurate focusing but do wish for less noise at ISO 1600-2000 range. The sensor is VERY unforgiving for under exposure. It'll be interesting to pull out that old 400mm/5.6 and put a 1.4x on it and see what it can do in the field as a nice lightweight handheld lens!! I'm a still photo shooter--digital and prints up to 36"--almost never do video so it's immaterial the specs on that. I'll use my iPhone video--ha! My husband who shoots serious wildlife and video uses 7D for stills and the Canon XA 20 for his video.

A clue about your specific needs, that is. I wonder if Panasonic or Sony have a clue about how to make products that appeal to the majority.

The popularity of a camera like the 70D (not to mention the 5D3 when ML came out) suggests that your "majority" is very likely a minority. Most buyers will be looking for integrated imaging devices, not specialized stills or video cameras. And since 4K is the future, while HD is the past, that is what is going to drive those buyers, especially when they start to buy 4K TVs and see the difference in quality. People who buy 4K TV sets (in other words, high end buyers - the same folk who buy most high end DSLRs) are not going to be interested in shooting HD afterwards, they will want 4K. So who will they turn to? Apparently that isn't going to be Canon.

The following was Canon's own description of the target audience for the original 7D:
" WHO IS IT FOR?

Whether you’re an enthusiast looking for the most advanced digital SLR camera in the market at this level, a professional looking for the perfect back-up camera to an EOS-1 series DSLR, or even a converted videographer looking for a second camera to shoot Full HD movies with, the EOS 7D will more than meet your needs. "

I find it rather unlikely that a follow-up would target a vastly different group of users.

 

[Lawliet]

If you already have a camera for stills and need a serious performer for 4k you would be crazy not to go GH4.

If HD is a secondary usage I'd look at the A7s as well. That one reads the full sensor and samples down - better raw data to feed to the recorder or codec.
That's if you can accept the limited frame rate options. :-X

Indeed. That explains why everyone has one of these:

...instead of a screwdriver, crescent wrench, wire cutters, etc. :

dSLRs outsell mirrorless by >4:1, and Canon sells far more dSLRs than Sony (and Panasonic). Maybe 'majority' means something different to you? : :

Let the broken records keep on skipping away and we'll reach 50 pages in no time. Sorry to pick on you specifically Neuro... not intending to single you out, it's just the most recent comment.... but seriously folks, it's amazing how some of you continue to make your point over and over and over and over and over and over...

If the speed at which this thread reached 46 pages is any indication of the pent up desire for this camera it will be a typical canon "blockbuster." (Yes, canon does indeed succeed at catering to the masses.) I for one am quite interested and despite all the pages of repetitive opinions this thread has swerved off on some interesting tangents. There are some smart folks on here... I'm still dumbfounded with how an AM radio is able to work.

I cringe when I see those. It is a tool that does nothing well and usually leaves a mess behind....

 

[NancyP]

But Neuro, I do have one of those multitools, a Leatherman Squirt, for camping use (gear repair potential). OK, so it has a mini-scissors, a short knife blade, a small Philips and small slot screwdriver, a needlenose pliers, a file, all for 2 oz., $30 bucks.

Cool. Will the GH4 take my Canon lenses and do fast phase detection auto focus while shooting video?

Sure...but is that the only tool you have, the one you use for everything?

I have an EOS M, it's convenient and takes decent stills and video. I also have a 1D X and a good camcorder, for when it matters. The jack of all trades is expert at none.

Something tells me that by the time 4K displays go mainstream, Canon will have cameras for the mainstream to go with them* -- if success in the DSLR market requires it. While those who adopt 4K TVs early might be the same slice of the market that buys high-end DSLRs, I don't think they comprise a majority of the market Canon depends on for its bread and butter. I don't have a source (so someone feel free to correct/corroborate), but I believe Rebels and 70Ds make up a far greater market for Canon than pro gear.

We have to remember that this is about business . A tit-for-tat strategy on feature set vs. feature set with the competition does not necessarily mean good business. Only Canon decision-makers have the inside information to support their strategy, and the proof will be in market performance and shareholder value.



*Imagine how awesome 4K with DPAF will be!

 

[that1guyy]

Yeah Canon may eventually add 4k. That just shows Canon is no longer an innovator, just a follower.

Errr, Canon released a 4K DSLR 2 years before anyone else. How is that considered being a follower?

 

[Loswr]

Yeah, maybe Canon should follow Sony's innovative lossy compression that eliminates data from RAW files, or follow Panasonic's innovative inability to make a successful dSLR and give up like they did. 'Cuz, you know, DPAF and the ability to accurately autofocus track a moving subject during video, that's certainly not innovative. :

 

[Woody]

Canon is not always the first to introduce new technology in cameras, e.g., video (that went to Nikon D90) or autofocus (Polaroid/Pentax/Minolta) in DSLRs. Although they are sometimes late to the game, they always succeed even if they play catch-up later. Being the technology leader is no guarantee that the company will succeed, look what's happened to Polaroid, Pentax and Minolta.

So far, it's clear that Canon does not have the latest sensor technology (goes to Sony) or fastest live-view AF (goes to Olympus/Panasonic/Sony). Now, we'll see when and if they can catch up with the competition. Dual pixel AF is promising but it's not there yet.

Sometimes when you are following someone and they go off a cliff, it's a good thing that you had time to stop.....
