EOS Bodies / Re: Bingo! New Canon 5Ds has 50.6 MP new rumored specs
« on: January 30, 2015, 05:44:38 PM »
Those small pixels give us ISO 16,000 in the 7DII.

No, the Pixels of the 7DM2 are larger. Should be anything equal to a D800 (36MP).

By the way...never wondered why ISO 16000 is no real full stop in the exposure-line? ;)   I guess the cam already pushed it internally. The 7DM2 is quite likely @ISO6400, also. But internally the newer Digic will push it 1.3 stops up...
A FF with the same pixel density as the 7D2 would have 20.2*1.6*1.6 Mpixels, or 51.7Mpixels. (Actually the 7D2 sensor is a hair bigger than APSC so the crop factor is slightly smaller, perhaps 1.58?) A crop factor of 1.583 would give you a 50.6Mpixel FF camera, so my suspicion is that the pixels are the exact same size as on the 7D2.....

Sometimes I don't understand the customers... wanting a High Megapixel cam but ISO409600? ;)  Haha. Of course you get ISO6400 with that small pixels...

Those small pixels give us ISO 16,000 in the 7DII.

although we don't yet know if there is a H1 or H2 ISO setting... Too early to tell for sure, but not looking good....

It can't be not allowed to have any "sports themed" parties without paying NFL royalties, it would have to be can't have any NFL themed parties...... after all, if the party was themed for scuba diving, obviously there would be no NFL royalties....

Could you do it as generic football themed?

EOS Bodies - For Stills / Re: 7D MarkII Battery Performance
« on: January 30, 2015, 05:09:53 PM »
Hello Guys, exactly one month ago i had bought the new 7D MarkII.
Since this date i shoot ~900 Pictures with it. So in my opinion after 100 shots the battery level is down, and i
have to recharge the battery. This makes me think about it, the outside temperature in our country levels about 0 degree celcius! Has any one the same Problem? Or is it maybe the AF system who leeches out the battery?
Thank you
I have shot 250 pictures outside at -15C and used between 1/3 and 1/2 of the battery, so 100 does not seem right. I have shot 500 pictures outside around freezing and used about 2/3 of a battery....

What I have noticed, but so far it is a feeling, nothing scientific, is that in Live view the camera eats batteries much faster than the 60D did, but in normal use it is close to the same for battery life.

When doing AFMA of several lenses using Reikan Focal, it really goes through batteries fast. Somewhere in the range of 100 shots for a full charge.

So the same battery can last for 500+ shots or less than 100 shots, depending on what I am doing. Obviously, there is some combination of settings that eats batteries like popcorn... Does anyone know for sure what this magic combo of settings is?

Why does everyone assume it is a done deal that an Exmore chip will be used?

It could be Sony fabricating a new Canon design that they are able to produce more efficiently than Canon can in-house...

It could be Sony fabricating an existing Canon design....

It could be Sony fabricating a hybrid Sony/Canon design...

It could be a pure Sony design...

It could just be a rumour....

It could be a prototype...

It could be lots of things....

We don't know. Period!

I believe all amplifiers with SONY are on the CMOS and with CANON are not. How will they merge that logic. Complete change of logic on one or both of vendors' proprietary  DSP (digital signal processor). In Canon that means DIGIC 7S (s - for Sony sensors).

And how have they merged Sony sensor with Canon DIGiC 6 in G7 X?

BTW: currently I've got reasons to consider all that Canon/Sony tech exchange to be [CR0] eg. never going to happen. Still there is a chance I'm wrong.

Two whole  different sensors,  in G7X it is a Sony BSI, in the SLR  cameras there are Sony Exmor

But the Canon Sony RX100 clone has a Sony Exmor chip and uses Digic.
Who says they have to use any ADC part of DIGIC?
Are we even sure the ADC is part of digic itself?
I was under the impression that the A/D was done on an Analog Devices chip between the sensor and the processor....

what so many people seem to forget is that Sony sensors work better at low ISO and canon sensors work best at high ISO. Nobody is best across the board. I think it would be a step backwards for the industry to just pick one.

The lead that the Sony sensor has at low ISO is much greater than the lead the Canon sensor has at high ISO. Furthermore the Sony sensor has a linear relationship between ISO and performance where the Canon sesnor does not.

Another point that needs to be made is that you can outsource the production of your design. It is very possible that Sony can produce a Canon design of sensor more economically than in house at Canon.

Or can produce designs that Canon cannot (due to fabrication process limitations.)

Canon make steppers, part of the machinery needed to make sensors, Sony don't.

Well in that case it means that Canon is behind in another area of its business (whoever is making the plant equipment that supplies Sony or the company that makes Sony's sensors.)

There are three companies in the world that make steppers, Canon, Nikon, and ASML a Dutch company. I believe they all make the same generation steppers, though Nikon are well off the boil, and Canon lost a lot of market share to ASML as well due to very restrictive and proprietary attitudes. ASML have carved a substantial portion of the market out for themselves because of business practices, not technology.

How is it that you know this?

It is common knowledge for those that choose to learn. I believe I got the main bits from Thom Hogan's site but that was all garnered from business reports, all three companies have to file financial reports, as do any other companies in that business unless they are privately held, which given the investment and market is extremely unlikely.

I do appreciate your even temperedness, but many of the laboured points you argue can be unemotionally settled very easily with simple research.
What about Leeson? They make a very nice 5HP stepper motor and I have several in use on jackscrews for controlling satellite dishes.

My only point was Canon needs SOMETHING with competitive 4k that isn't $10,000.

Why?  Canon was the first to make a 4K dSLR, so clearly they have the technology.  The fact that they haven't brought 4K down the lineup indicates they haven't seen it as a need so far.  I suspect Canon knows more about their business than you do.

Yes they have it. That's the point. The last FF bodies released were 2013. 4k was widely a non-issue at that time.  2015 is a new day and quite the opposite is the case now. Point was that these NEW bodies should have it for this round for the next 2-3 year life cycle

Giventhe current market penetration of 4K TVs (or lack thereof), I suspect it's still widely a non-issue.
I believe the market forecast for this year is for 4K TVs to outsell 2K TVs..... At my local best buy, the 4K section is now bigger than the 2K section. There is still not very much content, but people are buying them.....

Canon: All right. Who makes the sensor? The battle of wits has begun. It ends when you decide and we both take pictures, and find out who has Canon... and who has Sony.
Rumours guy: But it's so simple. All I have to do is divine from what I know of you: are you the sort of man who would put the sensor into his own camera or his enemy's? Now, a clever man would put the sensor into his own camera, because he would know that only a great fool would reach for what he was given. I am not a great fool, so I can clearly not choose the camera in front of you. But you must have known I was not a great fool, you would have counted on it, so I can clearly not choose the camera in front of me.
Canon: You've made your decision then?
Rumours guy: Not remotely. Because sony sensors are designed in Australia, as everyone knows, and Australia is entirely peopled with criminals, and criminals are used to having people not trust them, as you are not trusted by me, so I can clearly not choose the camera in front of you.
Canon: Truly, you have a dizzying intellect.
Rumours guy: Wait till I get going! Now, where was I?
Canon: Australia.
Rumours guy: Yes, Australia. And you must have suspected I would have known the sensor's origin, so I can clearly not choose the camera in front of me.
Canon: You're just stalling now.
Rumours guy: You'd like to think that, wouldn't you? You've shot with a 1DX and 1200F5.6, which means you're exceptionally strong, so you could've put the sensor in your own camera, trusting on your strength to save you, so I can clearly not choose the camera in front of you. But, you've also bested my Tamron, which means you must have studied, and in studying you must have learned that man is mortal, so you would have put the sensor as far from yourself as possible, so I can clearly not choose the camera in front of me.
Canon: You're trying to trick me into giving away something. It won't work.
Canon: Then make your choice.
Rumours guy: I will, and I choose - IS THAT A NEW PHOTOSHOP RELEASE?
Canon: [Rumours guy gestures up and away from the table. Canon Exec looks. Rumours guy swaps the cameras]
Canon: What? Where? I don't see anything.
Rumours guy: Well, I- I could have sworn I saw an upgrade. No matter. First, let's shoot. Me from my camera, and you from yours.
Canon, Rumours guy: [Rumours guy and the Canon exec shoot]
Canon: You guessed wrong.
Rumours guy: You only think I guessed wrong! That's what's so funny! I switched cameras when your back was turned! Ha ha! You fool! You fell victim to one of the classic blunders - The most famous of which is "never get involved in a land war in Asia" - but only slightly less well-known is this: "Never go in against a Sicilian when photography is on the line"! Ha ha ha ha ha ha ha! Ha ha ha ha ha ha ha! Ha ha ha...
Rumours guy: [Rumours guy stops suddenly, his smile frozen on his face and falls to the ground dead]
Neuro: And to think, all that time it was your camera that had a canon sensor.
Canon: They were both canon sensors. Sony is building to our design.

Has anyone stopped to consider how disgusting humans look in 1080p close-ups and that 4K, 8K etc. are truly terrifying developments?...
I find it amazing how you can take a picture, and then pixel peep to see details you would never notice in the real world....

O.k., I know we're talking about rumors here but I wonder what that rumored 53MP Resolution will actually be. 8910x5940 or 8940x5960 or 8970 x 5980? Something even more odd? Why not just 54MP (9000x6000)?

9000x6000 ... will come first in a mid 2018 Apple iMac and/or a Dell monitor ... when evyery other company aorund brings 8k monitors, they'll have it at "9k". Just like their late 2014 "5k" devices.  8) 

That would more likely be an 11K display, 5K is almost twice the pixel count of 4K (14MP vs. 8MP), where 9K would just be 25% more than 8K.

It really depends on the bandwidth of the connectors though, Displayport 1.3 tops out at either 4K@120Hz or 5K@60Hz.
I supposed given that 8K is supposed to be a 120Hz specification, it would make sense that some manufacturers would try to make a 60Hz panel for whatever connector they happen to come up with that supports 8K. However, I really hope that everyone just switches to using a 120Hz refresh rate industry wide, it makes a big difference in motion quality and at that point we won't be hurting for resolution like we are now (yes, 1920x1080 is super jaggy and we've had equivalent resolutions on PC since the mid 90's).

In 1974 I had a 800x480 4096 colour graphics display. It took almost 30 years to double that resolution and now 8K screens are starting to appear as prototypes. This is a very quick jump in a relatively short time.... some believe that displays will plateau at 16K... whatever you believe, we are living in exciting times for digital imaging.

this looks definitely fishy... I don't think Canon will exchange DPAF for more DR...
That would help much on Sony's already strong video business...

Canon may do what Nikon does: deliver a design to Sony for fabrication rather than fabricate it in-house.
FINALLY! Someone gets it!

Just because Sony fabricates it does not mean they designed it. The place where I work has been sending designs out for fabrication for 40 years.... we hold the patents, they sign an NDA. No fabrication house is ever going to violate an NDA (Non Disclosure Agreement) because if they do they will lose all future business from everyone and get sued back to the dark ages. Heck, during the "cold war" we were testing satellites for the Russians and the Americans.... competitors WILL use the same service if that service is the best.

Reviews / Re: Impressions from 7DMkII and Comparison to 7D
« on: January 28, 2015, 06:59:22 PM »
Such low level screen dumps are close to useless for comparisons.

What do you mean with low level? The resolution is limited ba the moderators. I do this the first time. In my blog they are full resolution... This means that I have to treat them diferently for this forum. right?

And you can see what is important: The 7D2 shows at each Iso level a higher level of contrast as well as color depth.

The images were taken as jpg. because at the time I shot them no Raw engine was available..

You posted these months after raw engines have been available.  The rest of us manage to post 100% crops etc that can be evaluated on this site.

AlanF: Thank You for your remarks. In Future I will use the 100% crops, too... The Post on this page was done month after
1 I took the images
2 I wrote a blog entry in my blog in my photographic website
3 after the moderators here killed my links - sorry for that, they did it against there statements without any warning or message- I decided to publish these images here: you see the date taken in the file name. The raw converter came one or two weeks later
4 I am an amateur. I do have some time to write a blog and to follow the discussions or start discussions. I am in a learning phase in this matter... I do the same on m43 where I do not have any issues Witte the moderators doing exactly the same....

I see it as a big compliment, that people on this side consider me as a real professional...
BTW, just in case nobody else has said it yet, Welcome to the forum!

And when you step into those two models, you're in the RED Scarlet price range

Which you previously showed to be within your budget. Canon makes 4K Raw cameras. What you want is an inexpensive Canon 4K rig. Assuming the thermal design of the rumored body is adequate, I don't see any reason Canon wouldn't enable it (as at that point it would be largely software).

Either way, the notion that an iPhone will record 4k before a Canon camera is demonstrably false. ;)

[If video were my thing and I had the budget, I'd go down the RED path too]

Do you believe it was announced before the C500 or 1Dc?
certainly not :) , but they did beat Canon to a sub $1000 device.... after all, my comment was about the part above bolded and in green,  and neither the C500 or 1Dc is inexpensive..

and all that said, I would be willing to bet that the video from something like a 70D up-sampled to 4K would beat any video coming out of an iPhone.
