EOS Bodies / Re: New Processor for EOS line
« on: September 24, 2011, 03:35:54 PM »
There is a quite reliable source indicates that the new EOS body will having a brand new processor and it is not the digic5 appears in the powershot s100 and sx40. Anyone beside me hearing this news also?

Well the EOS line will not have the DigicV as it is in the S100. The DigicV in those cameras is limited to fit the uses of the camera. DigicV in the EOS cameras will be fully powered.

So I guess in some since you could be correct.

I doubt there will be more than one Digic5 processor, too costly to design and manufacture different processors.  But yes, via firmware, some features could be disabled or slowed down but unless Canon has some big surprise for the world, there are no new "magical" image processing techniques that would only be added to the new DSLRs.

That's exactly what I said.

Ok,sure if that's what you meant then I should have prefaced my remark with "I agree..." before adding my comment that it would be the same chip and any differences would only be via firmware.

More competition is ALWAYS better for the customer.  And if nothing else, they will (and probably already have) drive Canon and Nikon to release better products at a faster pace.

Absolutely!

One of the big issue with high MP count sensors is diffraction, and with this camera diffraction begins at only f/5.6, many will say that it only begins there, but you really will notice the effect at f/11 and probably at f/8.  Cameras like the 5D MkII begin diffraction at f/13. 

The problem then is control of DoF, fine if you're using fast primes, but as a landscape camera?  Well maybe then it's not the best choice to make

Yes but just to clarify for people who aren't familiar with the physics.  Diffraction effects are caused by the lens, specifically the aperture (light bends when it passes an edge, creates bands through a slit, and rings through a small circular opening).  The smaller the aperture the greater the effects of diffraction.  The sensor itself does not cause any diffraction but as the resolution goes up for a given sensor size (smaller pixel pitch) the sensor will begin to resolve the diffraction effects and cause a softening of the image that offsets the increase in sharpness (and depth of field) that would otherwise be achieved by using the smaller aperture.  Therefore, for a given sensor it can be stated at what aperture this effect begins to be noticeable.

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.

Yes, but only slightly worse.  It's remarkable that they maintained similar performance measurements given the 50% increase in resolution.  But good point that they did make the choice to increase resolution while maintaining SNR, DR, etc. as opposed to keeping resolution the same while increasing SNR, DR. etc.

I think the reason for that choice is the market position of the camera.  Sony A77 is clearly not a Pro camera and for average consumers Megapixels still rule the day.

I know this article:
http://www.dxomark.com/index.php/News/DxOMark-news/Sony-A77-measurements-and-review-of-the-world-first-24-MP-APS-C-camera
Concerns a Sony camera but, I find the results to be encouraging for all of us.  Sony has demonstrated that, even with the high photosite densities of a 24.3 megapixel APS-C sensor, one can ascertain very respectable dynamic range, SNR and good high ISO performance, on paper anyway.  Perhaps this will assuage the fears of those with high megapixel fears.

And so, I'm excited to see what other manufacturers, particularly Canon, can do with their new sensors. What does canonrumors think?


Very good results indeed.  Interesting.  At 24MP Sony has been able to keep the SNR about the same as what was achieved in the 16MP sensor used in the Nikon D7000 which has to mean they've either lowered the noise in each photosite or they've managed to maintain the size of the photosites despite a 50% increase in the number of photosites.  The latter would be possible if they've been able to reduce the amount/size of circuitry that sits beside each photosite and if that's the case hopefully Canon has made similar improvements and we'll see a jump up in MP and DR while maintaining or improving SNR.

Overall the performance curves are not better and sometimes worse than the D7000 and 7D but that's a good result given the increase to 24MP.   A77 is still worse than the D700 and 5D2 as expected but pretty close which is interesting given the FF equivalent resolution would be about 60MP.

1D: I don't see them being merged. They are professional tools, not intended to the same people. And as every tool, they are made for a special job. So stop one of them and you make a lot of pro users very unhappy. Furthermore, if they are really merging, why the price would be closer to the cheaper model? If it become a double side knife, it would probably cost more than a previous single side one. :P

Neither group of pros would be unhappy with a merged 1D provided that it did everything that each of the split lines do.  So if Canon has the technology to have a FF high megapixel camera that can do 10 fps then both groups are happy.  The price would be lower because now they are designing and manufacturing only 1 body with the combined sales volume.

Just for the record this is my guess:
My guess is Canon is going to release a hybrid video/photo camera (or at least video priority) or high resolution cinema quality camera that uses an EF mount, BUT at the same time they're going to announce a new EF mount series. One that is targeted towards video, like lenses with power zoom. I bet that USM technology, the motor used in some lenses for AF, could also be added to the zoom; it would be quick, silent and be passive if older cameras don't support it. It would be named like "EF-Z" for its power-Zoom feature and be oriented towards serious videographers and cinematographers. They might also be able to borrow some of the optical fomulas from there video cameras and put it into an EF lens package(though pretty sure highly unlikely because of sensor size differences). This would all also answer the possible rumor about Canon's "photo and video department merge or working together."

If the above did happen I would consider that "historical".

Edit: I just realized that someone else had said something similar earlier on in this thread.

Not sure, but I believe that the optical elements that move during zooming are larger, heavier, move further, and move in more complex ways than do the focusing elements.  If so, the very small and fast moving USM mechanisms might not be effective for moving the zooming elements in a large lens nor would zooming need to be done so quickly.   Power zooming just wouldn't need USM type designs.  Someone else may have better info.

Lenses / Re: New L Series Lenses coming out with the 5D Mk3?
« on: September 23, 2011, 04:51:05 PM »
If you ask me... Canon really needs to develop the 200-400 at f2.8 instead of f4. The combo of the 70-200 and 200-400 would be great for sports journalists.

I'm not sure that a 200-400mm f/2.8 - a lens that would likely weigh >15 lbs and cost close to $20K - would be 'great' for anyone...

Totally agree with that.  There is no panacea in optics... there is always a trade-off.  The 400mm f/2.8L IS II is already 8.5 lbs so neuro's estimate is probably close and therefore it's just not portable or cheap enough for mass market.

Yes, the DLSRs will be using a new digic6 flux capacitor. Never miss a shot because you can always go back and get it.

Well said!  +1

It's amazing that some (certainly not all) people read the rumors posted on this site and take them at face value and then proceed to sell a lens or a camera thinking that they will fund the new whatever on release date.  The CR guy is posting based on "best guess" so why would that be enough information to start selling equipment to get a jump on buying "vapor equipment".  I don't understand. 


Good point, very true indeed.  However, one of the reasons people come to this site is to hear about rumors or leaked info about upcoming gear and the implied value is that CR Guy has knowledge of the industry and contacts that are better than us mere mortals.  On that basis we have an expectation that CR Guy vets the rumors, can spot the crap, can look for corroboration, and wouldn't post nonsense without saying so... i.e. putting a CR1 or even 0 rating on it.

In the case of this "Sept 22 pro product announcement" I think the ball was dropped a little bit and CR Guy has owned up to that by posting an apology and commenting that he'll be more careful about posting anything from DigitalREV.  Props for that.

Other reasons some people might come to this site are to talk about gear with fellow gear heads and to be entertained by bold and ridiculous claims by certain members.  And on that point, this thread certainly delivered!  :)

ok guys ill admit i was talking rubbish but i did have high hopes as for being a troll no you have that wrong I'm afraid but hey thats your opinion.

+1 for admitting it

This is rubbish i need to go full frame but don't want a 5d mk2 cause its dated and i want a body to last me 3 years which would mean it would be a 6 year old product canon get it together

Hey shooter, you've made some bold claims and launched a few insults over the past few days over your confidence a new DSLR would be announced today.  How about an apology and an admission you had no facts or inside intel?  And I had my hopes up that you were right although it will still be Sept 22nd for a while longer and maybe it will happen tomorrow so you'll only be a day off.  ;D

I think I'm going to stop posting DigitalREV tweets, they've done this twice previously. Once for a Rebel that already existed, and something else I don't remember.

Fair enough CR Guy, however, you also posted an update that said "Another person with an invite is telling us that the program only mentions, ink, laser, & multifunction printers" so it would seem that we have multiple sources of mis-information.

eagerly watchin the clock and routingely refreshing a bunch of web pages...

tick, tock...

Where was the event to be held today?  I don't recall seeing that in any of the postings.
