New AF design

Ok, guys and gals; couple more hints I've heard. Please do not flame, these are not facts but only chit chat results with 'a friend'. They might not be correct, but maybe they are:

  • New AF design: improved version will be used in next 1D series.

  • 100% viewfinder coverage

  • 2 (or more) speeds (fps) with different size handling.

  • Body: a sexy one

That's all for now. More speculations huh

Expect more moon shining (more clues from Canon) before and by this weekend. Announcement next Tuesday (Europe time) most likely.

PLEASE NOTE: these might not be correct. I am writing them just to have something to talk about during our free time and writing them for whom like talking about 'stuff'. If this message offends anybody (some miserable 1D users along with Nikon and Sony users) they can just kiss my lens!

That's why I want 1Ds5

There will be almost no work on 1D-series AF...

...basically because:

1. There is no need to re-develop it.

2. There is not enough time available to afford an complete engineering design-and-production cycle.

3. There may be minor tweaks and tuning on HW, but we will see most of them in Software (code is still not fully mature for the latest HW version).

Furthermore, and nnder some shooting conditions, and for some applications, you should expect a better, real-time integration of the AF subsystem with services/functions carried out by the DiGiC image processors, in the near-to-mid future (as more real-time video feeds are used and collected for shooting purposes).

Re: New AF design

MaxFX, what's your feeling about details below?

Eos Numerique has some connections with Canon crowd, they know about cashbacks in advance, etc.

Now, the admin just posted :

http://www.eos-numerique.com/forum/showthread.php?p=899361&posted=1#post899361

  • EOS CANON 5D-MARKII

  • 24 millions de pixels

  • new battery, new grip

  • Proc DIGIC 4

  • video

Prix : 2.600 Euros.

Can you add details on top of these ?

Re: There will be almost no work on 1D-series AF...

I don't know... maybe minor tweaks or minor improvements. But even those tweaks (adding a few more points, etc.) will bring us new AF design, correct? Maybe they did already finish the tweaks for failed 1DM3 and added a few more points for the next one and they will use the base of that AF system in this camera. I don't know... I wrote what I've heard.

Re: New AF design

My feelings? That's funny
Well, I got good feelings about them all hehe!

Only the sensor size... It might be little less than that. I am saying this not because I'd know the exact size, I am saying that because of the Sony A900 pre-view on DPR. If you read it, they claim A900 has the highest MP camera right now. I am sure these guys have new Canon FF and they already know the difference of two sensor sizes. They wouldn't bother to make that claim if new Canon had bigger sensor size.

No. That is not a new design (not in the short term, though). There is no real need for additional AF points (the EOS 1D Mark III offers better AF footprint/frame-surface coverage than competing solutions).

Maybe they did already finish the tweaks for failed
1DM3

...1D Mark III (and 1Ds Mark III) carry Canon's fastest and most capable AF electronics produce to date (superior to any past 1D implementations).

Two out of three *is* bad.

1 bad. There is a need, and a desire to not only re-develop it, but improve it.

2. There is not enough time available to afford an(?) complete
engineering design-and-production cycle.

2 bad. Sure there is, R&D doesn't START at the end of a production run!

3. There may be minor tweaks and tuning on HW, but we will see most

People who claim to be open minded never see it my way.

...It is not R&D the ultimate goal. It is revenue, and it starts there.

What's your current occupation? Have you ever worked in Canon?

Canon AF is being redesigned

Thecomplainer seems to be out of touch with the reality of Canon's SLR focus systems.

1. There is no need to re-develop it.

Yes there is, and it is generally known that the current Canon AF systems have reached their limits and that Canon have embarked some time ago on completely new designs. The current systems work ok for "non-demanding" work, but for small targets or moving targets with small DOF lenses (long teles and large aperture) things are much more difficult. Increasing pixels and improving glass make errors more visible. There is a pursuasive summary of Canon's general SLR plans including the re-development of auto-focus on this rumour site.

http://www.northlight-images.co.uk/cameras/Canon_5d2_3d_7d.html and look under August 22.

"The 1D3 AF saga has deeply embarassed Canon, who are in the midst of a complete AF redesign from the 1 series down - this design team has been given considerable authority and resources. AF based on the new designs was specifically left out until next year's models (early 2009)"

Other information in this particular source has proven to be correct in what has happened since August 22 and other knowledgeable sources support the general thrust that Canon will be incorporating totally new AF systems in cameras from 2009.

2. There is not enough time available to afford an complete engineering design-and-production cycle.

No-one said there is, the redesign has of course been underway for some time.

...1D Mark III (and 1Ds Mark III) carry Canon's fastest and most capable AF electronics produce to date (superior to any past 1D implementations).

Which by observation is not good enough. It is well accepted that there are problems with the last 1D and reasonably well accepted that there are fundamental limitations to the performance of Canon's AF in all current models.

Most people will never come up against these limitations, but if you shoot using long lenses or large apertures in demanding situations you surely will.

(demanding situations = small DOF lenses plus moving targets, changing targets, complex targets, strong backlighting, small targets or competing clutter).

i hope you haven't otherwise it doesn't seem like they get it yet

...Interesting, you are pretty much describing the typical circumstances where any AF system available today is most challenged... Seems like an academic description, indeed.
