Is it wishful thinking to hope for a firmware update sometime after release to enable dual iso? Is the hardware capable of this?

Blimey - let's see the camera first before we start speculating on/wishing for firmware updates!!!

And you have missed the point - which was meant be humorous (remember that concept) - that while we are discussing a big new camera launch, discussing the updates to firmware is a little premature!

I forgot to put in a smiley face - I tend to prefer using words on forums - but I forgot about the literalists on here. My bad.

I'm simply asking whether or not dual ISO will possible down the track. We already know the camera's specs, so what difference does waiting until the camera is released make with regards to asking the question? Fair enough you were trying to make a joke. It didn't seem like it, mainly because there was no humour involved. Anyway, if someone with more tech knowledge than I could answer the question, I would appreciate it.

Spot the use of the word "Blimey"...

 

[rcarca]

Using the word "blimey" automatically makes what you're about to say funny? Let's agree to disagree. Perhaps rather than clogging on these forums with your "humour", you could let those with the right knowledge answer the questions.

Doesn't necessarily make it funny, it flags the intent.

And the reason I started going negative way back was so that we'd never end up in this position years later where Canon ended up totally blowing their dominance

Don't worry, Canon still totally dominates the ILC market.

 

[Diko]

Like I mentioned earlier, I'm hoping for a good improvement in this spec, I will be the reason for me to purchase the 5DIV. My hunch is that if the camera had 14 stops...

Bad hunch. It is clear as a day that it will be 13.5. That is the whole current generation CMOS DR.

 

[Loswr]

The 1DX-II already has Sony DR and then some albeit lower MP and sharpness.

You need to compare at the same scale and use the Print not Screen option, so no, compared fairly, it does not.

I was not aware that you can get more DR by downsizing the image...this is true? ???

If one defines DR as a function of FWC/noise, since downsampling reduces noise (averaging), it increases DR.

You can play that game until all cameras are equal (two adjacent pixels, one white and one black), but if you choose a consistent output size somewhere in between (in the case of that chart: 8x10 at 300ppi, I believe), you get different numbers.

Yes, but it's a game. In fact, I totally disagree with LetTheRightLensIn that you should compare scaled values. Although those normalized 'Print' values are useful for engineers (and fangoils and measurebaters, too), it's the non-normalized 'Screen' values that should matter to photographers. For photographers, what matters is the difference between the brightest highlight detail and the darkest shadow detail that can be captured.

If LTRLI is shooting a scene with 14.7 EV between shadow and highlight detail, his beloved Exmor sensor rated at 14.8 stops by DxO's normalized value will not be able to capture the full DR of the scene. Detail will be lost in the highlights, the shadows, or both (depending on the selected exposure). Downsampling the resulting image to 8 MP will increase the calculated DR of the image to 14.8, but it won't bring back the details lost at capture that fell outside the actual 13.7 stops of true ('Screen') DR of the sensor.

Not just more DR, more of everything except resolution. Normalization is a pseudo-science popularized by DXO among some photographers. The idea is that you can't compare apples with oranges, they are different, so you must first convert both to grapefruit and decide which one is tastier.

Normalisation is a process that most photographs undergo. Few people post full size images online. And even if you do, most websites will resize them. Unless you're viewing a file at 100% resolution then you're normalising it. It's not some weird fad, it's a normal part of post processing and sharing photographs. And if you print, you likely print to the paper size, in which case again you're normalising the image.

Clearly, end users tend to view whole images, whether in print or on screen. Therefore comparing certain properties on an image level is a reasonable thing to do. Not that 1:1 viewing doesn't have its place. But to dismiss normalisation as some dark art or weird fad is... absurd.

Edit: I agree with Neuro that reviews should focus on what is useful and important on a practical level. But I think, given as I say comparing normalised* images is how most photographs are viewed most of the time, it's a reasonable thing to do. For instance, some people criticise the 5Ds's noise versus other cameras like the 5D3, but if you take a photo and view it at the same size, the 5Ds file can actually be less noisy; unless you are cropping (which is obviously a valid use case for this camera, but not the only one), you'd be misled to think a 5Ds file was noisier.

*unless I'm misusing this term... normalised as in viewed at the same size, right?

Even as you have rewritten it, the Hasselblad IS still a DSLR.

I beg your pardon.

Seriously?

What about the Lunar and Stellar too? At least you can actually buy them today....... :

That's a hasselblad, it's not the hasselblad. The one which was being discussed predates the Pentax w/pixel shift, that one doesn't.

But to dismiss normalisation as some dark art or weird fad is... absurd.

True – normalization is certainly useful and important in some cases. But it's important to understand what your doing, and why, or you risk looking like an idiot.

Take, for example, this post on Digital Camera World that purports to explain, "...what you need to know about capturing all the tones in a scene," where the author states that:

[quote author=Markus Hawkins on Digital Camera World]
For instance, the Nikon D610’s dynamic range has been measured at between 13 and 14.4 EV at ISO 100.
[/quote]

The D610's DR has been measured at 14.4 EV. Tossing out a statement like that, particularly in the context of 'capturing all the tones in a scene', shows a total lack of understanding regarding what was actually tested.

It's as clear as day you are shooting information out of your posterior.

Current generation of CMOS dr?

Canon makes their sensors to suit the camera.
However it should be under 14ev if it's still 14bit raw files.

 

[JohnUSA]

At the risk of getting my hopes up over unconfirmed capabilities, if Canon T Engineer called me up as said "two options: 1. we increase the DR of your 5D by 2EV, or 2. we enable you to adjust the focus in post by up to approximately an eyelash's length, I'd jump at the second option. Jump. For my usage, that would save far more photos than would be made possible by the additional range.

Do you have your AF calibrated?
Saving photos by changing focus within eyelash length seems more like a back/front focus issue.
I'd rather calibrate than shoot double the image size & use Canon DPP.

Think of shooting a person hand-held wide open... subject is swaying a little and so is the photographer. Each probably move more than an eyelash length. I shoot weddings... I'd welcome the new option.

 

[unfocused]

That's magical thinking, along the lines of "I ate a pepperoni pizza before the Super Bowl and my team lost, so I will never eat a pepperoni pizza before a Super Bowl game again."

You can tell yourself that, but really, Canon isn't making their development decisions based on whether or not you make negative comments on a geek forum.
