46.1mp Canon DSLR Previewed at PhotoPlus 2012? [CR1]

[Tov]

I think the Ds series always had sufficient AF and low ISO performance but still came at a prize.
This new 46.1 mp beast isnt going to be any different.
However I doubt that it is going to appear very soon. I think that Canon marketing came up with the idea of spreading a rumour of a very high mp camera so people would think twice before taking the plunge to the D800.

A lesser Af system would mean taking a step back.
I used to have to focus manually but now with auto-focus life has became peachy.

I'm just wondering...

46.1MP is 8316x5544. 14 bits of usual information make 16384 levels of a colour. Is it not so, that increasing the resolution to such a level you should also remember to increase the colour depth to avoid the banding, which may occur at the pixel level? Does Nyquist-Shannon rule has anything to do here or not? If so - is the 46.1MP maximum usable resolution in 14 bits domain?

Guys knowing more than me?

You won't experience banding with 14-bit color in most cases, regardless of the image resolution. If you did, it would usually be in large regions of smooth gradient...such as a sky. That already occurs on current and past generation cameras, and is sometimes exacerbated of how your computer screen is calibrated (not caused by, simply made more apparent).

Based on the current rumors, Canon is also boosting the bit depth to a full 16 bits, so this would be a 46.1mp sensor with a 16-bit ADC, which would produce some pretty incredible tonal fidelity, as well as add the potential for a total of four stops or so of improved DR (assuming Canon really does get a handle on their read noise, we might go from an average of 11.something stops to 15.something stops.)

Really? I would imagine it will have a different AF system. The 5D III is a prime candidate for a great AF system, but a megapixel monster with a low frame rate? I guess I don't really see it getting the top-end 61/41pt AF system. I certainly hope it gets something better than the 6D's 11pt AF and even the 7D's 19pt AF systems, though.

Why? If it is a 1-series body it will most probably have the top AF system. Wasn't this situation the same with 1DsIII ?

AF, etc
first Canon need a sensor to compete with.
low read out noise
Large DR
There are non

That is true I am afraid . However, Canon might have a surprise :

Well, your assuming its a 1-series body. The current rumors either indicate its a 3D, or possibly some new line of cameras with a whole different naming scheme. Either way, if its a studio and landscape camera, I would expect the key selling point to be the sensor, not the AF system, and a complex, advanced AF system in a low-frame rate camera...well, that needlessly increases cost when it's not really needed or beneficial.

So nothing was announced at Photoplus? ;-)

I'd say the Frankenstorm put a bit of a dampener on everything.
But there's nothing at the Photoplus or Javits website to say the whole event was cancelled, so I'm assuming Photolus did actually happen.
But it would be a bit poor form if anyone did announce anything (and it would have just gotten lost in the noise anyway), so nope, nothing fun...

Finally some relative credible rumors and 16 bit. I believe will be in a 5D3 Body (not 1D) aimed directly to studio work. At those specs will be at around $ 5K.
For what i do... regarding photography... 46 MP is a blessing from haven

I really, really hope this will be true

if its a 5Dmk3 body and $5000 count me in if its a 1D body i'll pass
I wouldn't mind a high MP body for certain stuff

This might be off the wall for hard core students of Canon history who can predict what Canon will do -- but it will be interesting to see which of two paths Canon will take with this puppy. Assuming this is a 5D style camera:

1. further the specialization (and sale) of different bodies by preserving both a 5D and a high MP camera, optimizing each for their respective niches and preserving the sale of both, i.e. a 5D4 appears in addition to the 46mp body.

2. compete more directly in the D800 style market, but at a higher price -- , i.e. merge the 5D and high MP lines into one camera that can play well at both 46mp and 21-ish. Use it for studio, landscape, location, wedding, lightweight sports and wildlife. Odds are that the 46mp body won't appear until 5D4 time anyway

I was thinking along the same lines. If this camera had crop-mode and 6fps - 8fps, it could really be a do-all kinda camera. If the 1DX had 22MP, it would be quite close to perfect. WiFi and it would be.

If it's light enough, I'd be fine with a 1-series body. I handled my friend's Nikon D4 and was impressed with it's weight. I could totally carry that all day.

It just kills me when people complain about the weight of todays DSLRs'. :

I'm curious what that comment is based on? As I understand older film SLRs, they did not have nearly the same amount of "stuff" packed into them. They did not need the kind of power modern DSLRs do, so did not need huge battery packs (which is where a lot of weight comes from). Modern electronics are also quite dense, and we pack a LOT of electronics into relatively small packages these days. I've never known film itself to be particularly heavy.

So, if film SLR bodies were heavier than modern DSLR bodies, what, exactly, made them that much heavier?

remember the canon 1V sans grip

Best... Form factor... EVER!

a 1D like this would be killer

In terms of weight, my lightest body is a non-interchangeable-lens Petri Rangefinder, then my mum's Pentax Spotmatic isn't far behind, and they're both nice and made of metal.
My EOS 3 is 780g without battery or lens, not far behind my 7D at 820g with no lens (not sure if with battery), the extra weight in them is going to the weathersealing, tough body, drive motor in 3 and those dual digics in the 7D must weight a bit...
Then the Medium Format big boys are Mamiya 645AF and Pentacon 6 at 1.7kg, and the big Soviet Tank Kiev 60 at just over 2kg (P6 and K60 weighed here with standard lenses).

The pentaprisms are the biggest killer behind metal weathersealed-bodies, Li-batteries and motor drives, the difference in weight between a sensor and a film cartridge is negligible.

Still, none of those are "too heavy" for me. There's definitely times I'd like an M9 (and not just for the IQ and prestige), but I'm generally happy carrying any body around.
Lenses, on the other hand, weigh a lot more (like 2kg for a Zeiss 300mm/4 and 1.1kg for the 180/2.8, with both of them in my bag i'm struggling not matter what body/ies i'm also carrying).

+1 You reminded me of my used EOS1n cameras I miss this kind of design...

 

[PVS]

5:4 Crop mode with VF support would be one nice addition.

As this is a rumour site. I've just heard that the rumoured Canon 3DX is actually going to be called a 0DX which tops the 1DX.

It's going to be a 100mp "ultra" medium format camera, it's going to have 32 bits of colour rendition and a full 24 steps of dynamic range. It will fit FD, EF and EFs, Nikon, Sony, Leica and Hasselblad lenses and will have 292 areas of AF focus points.

It will have thunderbolt, Firewire 800 and USB3/4/5 built in for future compatibility.
It will also have GPS, Bluetooth, Wifi built in and will have the ability to make phone calls. It will even call you when the battery gets below 10% and recharge itself with gravity induction from the moon at night.

The price point of this little 5oz marvel will be £1000 with a £300 rebate from any Comet store. You'll get a free cinema ticket to the new Disney Star Wars movie too. Coming in December 2012-2022ish.

Sounds like a bargain to me.

Only if it comes with a mouse for a squeaky clean sensor
