EOS Bodies / Re: 1Ds Mark III Has Left Canada
« on: July 23, 2011, 09:11:57 PM »
I noticed that the 1Ds is currently out of stock with Park Cameras and  Calumet uk. Hope that means the mark 4 will soon be here, or maybe it just means nobody wants the mark 3 anymore???

Just FYI, the 1DsIII has been 'temporarily unavailable' at B&H Photo since January.

As I said above, Why you are thinking that the 1DV is going to replace the 1Ds and 1D series, leaving nothing in the 1D price range ?

The merged 1-series camera - the 1DV - will be in the 1D price range, not in the 1Ds price range.

The thing is, the 1D price range is no longer $4K as some tend to believe. 

Canon is selling the 1DIV for $5K and Nikon is selling the D3s for $5.5K.
This is the new price range for this class of camera - whether you like it or not.

$5K is the new $4K ;).
Expect that 1DV to push that price at introduction - but then to come down to $5K within a year.

Canon does not want to sell you a 1-series camera for $4K anymore. These days are gone.

Moving the 1DV to FF will be just another justification for increasing the price.
You can see the same trend with the new 'big-whites' (300L, 400L, 500L, and 600L) - they are all more expensive than the lenses they replace.

Is price is merging too ?  ::)

Hehe, excellent point.

I fully expect that the 1DV will be a high speed, high resolution FF camera.

IMO, the 1DV will be initially priced at $6,000.
The 1DIV will remain in production for maybe a year and will continue to sell for $5000.
After this one year period - effectively a transitional period - the 1DV will drop to $5500 (or even $5000) and the 1DIV will be discontinued.

Some dismiss the merging of the 1-series on the grounds that Canon has always been charging $$$ for the 1Ds.
But that was then and this is now, as the saying goes.

Canon General / Re: Canon 3 Layer Sensor (Foveon Type?) Patent
« on: July 08, 2011, 09:40:31 PM »
As has been said already: this and other colour systems (bayer) have an amount of bleed.

Foveon color-bleeding is much worse than Bayer.
Bayer sensors use optical color filters, which are much, much better than silicon in filtering ‘undesired’ wavelength bands.

In a Bayer sensor there’s color bleeding because of 'cross-talk'.
Cross-talk is when light passing through the color filter of a pixel excites electrons in neighboring pixels.
This kind of bleeding is perfectly correctable and there are different techniques that do it.

In contrast, the color bleeding in a Foveon sensor is uncorrectable.
Like I said, silicon is much worse at filtering light of certain wavelengths compared to an optical filter.

(It's completely another matter that manufacturers use wider bands for the color filters in order to improve sensitivity - which, of course, results in poor color separation.)

You gotta admit: the wiki link you posted earlier on during our little skirmish, perfectly matched what was said in the white papers - R & G & B; nothing said about white, yellow and red.

Osiris is actually right about this one.
What you see on the Foveon web site is a logical diagram of how light is filtered.
The diagram certainly does not represent how the filtering is performed in practice.

As Osiris said, all of the layers in a Foveon sensor are equally sensitive to all wavelengths.
But based on the depth of a layer, only light of a certain wavelength band is supposed to be absorbed by this particular layer.
In practice, though, the absorption is far less than ideal, so color separation is (much) worse compared to using an optical filter.

Combining BSI with a 3-layer design is a pretty innovative idea.

From what I understand, though, both of these individually are already very hard to implement in practice.
So, I'm assuming that combining them in a single design will be even harder.

But if Canon can pull this off, it will be a sensor nirvana ;) ;) .

EOS Bodies / Re: End of the APS-H sized CMOS?
« on: June 27, 2011, 12:56:29 PM »
Why do you think Canon should stop APS-H sensors? What is the interest for Canon?

Because the 1.3x sensor is a lesser sensor than FF.  This means that:
  • if Canon charges more for the 1DIV than Nikon for the D3s, Canon will be overcharging for a lesser camera
  • if Canon charges less (as is the case today), the long term perception will be that Nikon is the premium player in the market and Canon is the discount/second grade player

As you can see, Canon has no choice but to abandon the 1.3x format - unless they want to be the perceived as the discount/second grade player in the market for pro cameras.

EOS Bodies / Re: The Land of Crazy or.... ? [CR1]
« on: June 22, 2011, 03:15:43 PM »
A FF 7DMk2 qualifies as crazy. There are good reasons for using a crop camera for shooting sports, wildlife etc .

+1000.

The 7D going FF is the most unbelievable rumor so far.

Other than that, there will be big changes in the lineup for sure.
The 1DV is going FF and the 60D is not positioned right, so it will undergo another makeover very soon.

These changes will affect the entire lineup in a big way.

EOS Bodies / Re: EOS 7D mrk. II
« on: June 16, 2011, 12:16:54 PM »
Can anybody verifi this?

No, this is a wish list.
The Digic V processor will likely handle very high data throughputs, so the 7DII won’t need dual Digic Vs, just a single one.
The other specs seem plausible, although I'm not sure Canon will take the risk of putting a flip-screen on a non-consumer camera.

EOS Bodies / Re: The Future of the 1Ds & 5D Lines [CR2]
« on: June 04, 2011, 12:15:15 AM »
Well, if Canon developed 120 MP APS-H sensor, why would they abandon this format now?  This rumor seems to be very unlikely.

Good find about the 120mp sensor, Idigi.

Note, though, that this is just a prototype sensor.
It indeed shows that Canon has the technology for a 30mp/9fps camera - at least in a testing/prototype phase.
It's in no way an indication, though, that the technology will be used to actually make APS-H sensors.

APS-H is just a very convenient and economical size for prototypes.
It showcases the abilities of a new technology to scale to FF sensors - while at the same time it's more economical and allows faster prototyping than FF.

APS-H is going away for sure.
From a marketing perspective it's a mistake to offer a lesser sensor in the flagship pro/sports camera when Nikon is offering a FF sensor in their equivalent.
Long term, the perception will be that Canon's flagship is either inferior than Nikon's (if priced lower) or that Canon is overcharging for a lesser camera (if priced the same/higher).

So, Canon actually has no choice but to put a FF sensor in the 1DV. APS-H will just hurt their business.

EOS Bodies / Re: 1Ds Mark IV & 3 Lenses in August?
« on: May 28, 2011, 01:09:57 AM »
Btw, Canon needs a strong holiday-season seller, so it's very likely that the 7DII will actually be announced in August/September together with the 1DV.

The rumors that the 7DII will come in 2012 are CR0.

EOS Bodies / Re: 1Ds Mark IV & 3 Lenses in August?
« on: May 28, 2011, 12:59:56 AM »
Well, August/September is the usual timeframe when Canon announces new products.

First in line for announcement is the 1DV. 

Of course the 1DV will be full-frame and come with more than 21mp, so I guess it could be considered a 1DsIII successor as well - in addition to being a 1DIV successor, that is.

Well, the abstract starts with:

So, I don't know. I assumed it's a zoom lens.

Canon General / Patent - 400-600mm f/2.8-f/4 zoom lens
« on: May 27, 2011, 12:36:58 AM »
Here's another interesting patent that Canon just received in the US.

It's for a 400-600mm f/2.8-f/4 zoom lens:

I'd say that this would be the new sports uber-telephoto - with a matching price tag, of course ;););

EOS Bodies / Re: 26.4mp 5D Mark III Mid-year? [CR1]
« on: April 17, 2011, 05:18:33 PM »
Very sensible rumor - even though it's hard to believe that the 5DIII will come before the 1DV (or the 1DsIII successor).

Still sticking to my prediction that the next camera from Canon will be the 1DV  8).
The 5DIII will come later. Same specs as in this rumor but with the 1DV sensor - likely 30mp, though, not 26mp.

The best source I’ve had about a 1Ds replacement has said it would be over 40mp and come in late 2011 or early 2012.


Try 50mp next time.

37-40mp is so last year 8).
