Lenses / Re: Lens Announcement [CR1]

Good to know. I'm wondering if there are any bodies planned for PMA @ CES, though.

Historically, Canon has announced many cameras at PMA over the years.
Will this PMA be an exception?

I also expect that the 5D successor will have a different, higher mp sensor. It seems as though the sensor is the real differentiating factor in the 1DX and I don't see Canon devaluing the line by using the sensor in other bodies – at least not in the near term.

My thinking exactly.

They may end up splitting the 7D into two lines, an enthusiast model and a pro model for sports and wildlife photographers who want the extra reach they are losing with the end of the APS-H sensor. 

Canon already split the former xxD line into the 7D and the 60D. Will they further split the 7D?
It seems to me that the 60D successor will need to be "re-imagined" again to be more competitive.
Can't tell how this will affect the 7DII.

Contrary to what many on this forum wish for, I don't think we will see an under $2,000 full frame model. I'm not even sure it's possible to produce a full frame body at that price point. 

Agree again. That would only devalue FF as a premium offering.
The 5DII is "affordable" enough already and I'm hoping that the 5DIII will stay at the same price point.

EOS Bodies / Re: Opinion - What EOS Will Look Like by Photokina
« on: September 24, 2011, 01:49:39 PM »
I think EOS will evolve a lot in the coming 12 months, the business of digital SLRs has changed with the advent of video in the segment. I figured I’d offer my opinion on the line partially based on things I’ve been told and things that just make sense to me.

Some of your points make a lot of sense but I also have different views on others.

A merged 1-series (1DV)
I find it strange that this camera is not out yet.
Canon, the pioneer of large DSLR sensors, currently does not have a pro FF model on the market - after the 1DsIII has been officially discontinued in some countries (e.g. Canada) and unofficially discontinued in others.

6D
With a merged 1-series, it is very likely that we'll see two FF models positioned under the king of the hill.
If I was working for Canon marketing, the 5-series will be split into a 5DIII ($2500) and a little 1-series ($4000).
The little 1-series camera will be basically the 1-series but without the integrated grip and some other minor differences.

7DII, 70D, etc.
The business of DSLRs has changed indeed.
With the D7000 and the A77/Nex-7, the price point of the 'enthusiast' class of cameras has moved down to $1200.
At the same time, we see mirrorless eating at the bottom of the DSLR market.
I thus expect some major changes of the non-FF lineup.
Canon needs an ultra-compact Rebel (if not mirrorless) and an appealing $1200 offering.
This will affect all 1.6x models. Can't predict at this time what will happen but I see re-alignments in all three model lines - Rebel, xxD, and 7D.

EOS Bodies / Re: DxOMark posted it's A77 results

I find the results to be encouraging for all of us. 

Interesting, I find the exact opposite.

I just compared the A77 to the D7000, which has the 16mp Sony sensor.
The D7000 came on top on all DxO measurements: SNR, DR, Tonal Range, and Color Sensitivity.
That's on the 'print' tab, which equalizes resolution; on the 'screen' tab, the D7000 is even better.

Sony pulled a Canon with the A77 - sacrificing image quality for the extra 'umph' of more megapixels.
Canon did it with the 50D and 7D, now Sony is doing with the A77.

Unlike Canon, however, Sony also updated their 16mp sensor (the NEX-5N) and here's the result:

This is nicely corroborated by the DxO measurements, btw.

This is actually almost standard M-O for Canon DSLR's. About 2 weeks prior to the real announcement, some Canon affiliated web site "accidentally" posts some tidbit about the soon-to-be-announced camera. In this case, it looks like it was the name. Other times, it was a photo, or a spec sheet, or even a full draft of the press release.

I'd say we can expect an EOS 6D to be announced anywhere from 1 to 3 weeks from now.

While I agree about Canon's M-O for leaks, I don't see a 6D announced right now.

As the name suggests, a 6D would sit between the 7D and the 5DII.

The thing is, there's no need for an even more advanced 1.6x camera than the 7D.

But if the 6D is FF, what features could Canon possibly cripple, so that the 6D sits below the 5DII ??
Make it a 1-fps camera with just a single AF-point ??

I'd say that Canon Australia is pulling our proverbial leg here ;);).

1DV rumors are in overdrive obviously.

The camera is coming for sure - but in September, not August, and with 28mp.
The 32mp rumor is bogus.

You heard it here first ;) ;).

Yes, they can be used for both video and stills, but they are optimised for their main usage. A video sensor will be low res to avoid line skipping as an example ?

Video sensors are no different than stills sensors but video sensors need to support much higher read-out speeds (60-120 fps for video vs 10-12 fps for stills).
One way to cope with the data throughputs at such speeds is of course to have a lower resolution sensor or to do line skipping (or 'thinning', as I've seen it called).

This is something that technology will definitely solve in the future, though.
A hi-res sensor designed to do pixel-binning (or some other trick) instead of line skipping will avoid many of the aliasing issues that current DSLR sensors have for video.

The Reds, and the other dedicated video cameras have a video specialised sensor and I am claiming that they are more expensive due to this.

I disagree with that. 
Economies of scale surely play a role in sensor costs but the REDs are so expensive mostly for business/marketing reasons.
RED are establishing themselves as the Ferrari/Lamborghini in their market. 
So, you will never see low cost cameras from them.

OK, how do things work at Canon?

By all accounts, Canon is a well managed corporation with a very good understanding of their market.

The whole idea of splitting the 5D into separate stills and video models is just silly.
It's a wet dream from someone who bought a 5DII instead of a RED - and quickly realized the shortcomings of a DSLR for film/video.

If Canon is to ever target the RED market, they will have a proper RED competitor, not a 5DII clone.
The catch is, this will not be a $2,500 model as the wet-dreamer hopes. Try $10,000 or maybe even $20,000.

Such a model will also come from the video division and will have an adapter for EF lenses.
That's how things work at well managed corporations with a very good understanding of their market.

1.Split the 5D line into a still camera and an advanced video feature camera.

that will not happen and everyone who is spreading such a rumor has no clue how things at canon work.

Exactly !!!

The 5D-split rumor first surfaced some time ago but now has been taken to the next level.
Canon is now presented as being strong but confused - wondering what to do with (the success of) the 5DII.

Give me a break, please.

The 1DV, 5DIII, and 7DII have been carefully planned long time ago.
No inside knowledge is needed to understand that - just simple understanding of marketing and product positioning.

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 ;) ;) .
