< 10 mins - will the website crash with our optimism?

It was explained several times in the thread, that obviously the timer is not adjusted for different time zones, but just New York

Because we don’t see what you see.
     AT CANON, WE SEE IMPOSSIBLE.
     So to us, it's Impossible to See... No wonder we all cannot see the "whatever" you want us to see... ha ha ha  :P

    Have a nice day.

PS: GMT now: 7:23am.

hahaha, made my day  ;D

Can someone please calculate at what time will the timer go off according to EST time, so we can adjust :)

Edit: OK, AUGS answered while I was writing, thanks

EOS Bodies / Re: A New EOS Pro Body With 46mp Next Month? [CR1]
« on: September 19, 2014, 04:58:08 AM »
I don't know if someone already posted this, but according to this site:
http://www.sonyalpharumors.com/sr4-no-other-new-camera-from-sony-at-photokina-sr5-new-generation-sensor-and-cameras-release-in-january/

"(SR5) Sony is preparing a BIG event in January! They will release a complete new generation of cameras with a new generation sensor. Cameras have those two features:
1) Very high resolution and dynamic range. One of them is a 46 megapixel FF sensor.
2) Very fast AF speed

I know it’s strange they did not announce those at Photokina. But that it is. I Thank All trusted sources for the info they shared the last couple of weeks. I hope you sources can help me to feed SAR readers with some reliable rumor about the next generation cameras coming in January!

-

A couple of notes: January announcement is 100% correct as it really got confirmed by highly trusted sources. So trust me on this"

I really hope Canon will not lag behind and this new EOS body becomes a fact

EOS Bodies / Re: Canon EOS 7D Mark II Specifications Confirmed
« on: September 11, 2014, 11:22:03 AM »
To all of you who say, that these specs are appropriate for a 2014 camera and not for 2012, bear in mind that with this replacement cycle, the next 7D will be available in 2019. What would you think of those specs even in half of that term?
You claim that these specs are the best package compared to the competition, but the competition will be releasing their competing bodies in the near future, not in 5 years. This camera sounds boring

« on: September 10, 2014, 07:14:47 AM »
IS will not benefit fast action. It may actually blur your images by trying to stabilise it, so turn it off. IS is useful for camera shake, if your shooting fast action at high SP then its no benefit, but is useful when panning or when the light gets low. IS is useful for stabilising the viewfinder tho, so you can track subjects easier at large focal lengths.

IS does nothing with moving subjects its primarily objective is to reduce camera shake. Mode 2 on some lenses aids panning.

Thanks for the reply. I know its objective is to reduce camera shake, my question is if I shoot hand-held, does camera shake have significant effect on the photos in high shutter speed, so that IS will be of use, or the high shutter speed itself eliminates enough the hand shake

Cheers,

Photography Technique / Benefits of IS in fast shutter speeds
« on: September 10, 2014, 04:57:17 AM »
Hi there,

I have a 5D Mark III and occasionally I shoot sport events (indoor as well as outdoor) with it. I shoot fast-action sports, so usually use high shutter speed to be able to freeze the action. So I was wondering if I have to buy new lens, is IS something that I will benefit from, or at shutter speeds which are higher than the focal lenght there is no significant advantage of IS?

Thanks  :)

My question to all of you who say that shoot 16-24GB per day: do you even have the time and nerves to go through all those photos more than once when you go back home?

EOS Bodies / Re: Are These The EOS 7D Mark II Specifications?
« on: September 02, 2014, 05:04:45 AM »
Regarding the sensor...very disappointing. Sounds like a re-purposed 70D sensor with a DPAF improvement. I was REALLY, REALLY hoping Canon would really show something impressive on the sensor front with the 7D II. If the camera really does hit the streets with a 20mp sensor, I fully expect it to have the same DR limitations as all of Canon's previous sensors. Extremely disappointing.  :'( Guess we'll have to wait for the 5D IV to see if Canon can actually step up their sensor IQ game or not...which is just...so far down the road...Bleh.

Also worried about the "fine detail"...I really don't want them to start removing AA filters. That is just a dumb trend that photographers like simply because they do not understand the value of an AA filter, or the ease by which AA softening can be sharpened.

+1

it sorta almost leads one to believe that Japanese Canon Fangirls post here where they were claiming that Canon feels they have Canon users trapped enough that it won't matter if the bodies they push out can't keep up as per sensors and even other features at times (still not a hint that they are actually moving any DSLR sensors to new fabs and the panny gets 4k and yet the super new 7D2 which was promised to have revolutionary video and this and that is still 1080p)

and yeah the AA filter-less stuff I am not a big fan of, maybe when we get to 180MP FF or 60MP APS-C or something.

Yeah, we really need sensors to significantly oversample the lens before we can legitimately start dropping AA filters. Otherwise we just end up WITH aliasing, and that's never good.

I was not really interested in the 7D II being a big video DSLR anyway...I don't really know that anyone truly was, you just don't get that cinematic look with a smaller sensor...not without having very wide apertures anyway (like a lot of expensive cinema lenses do).

The thing that I think Canon really needed to nail, and which increasingly appears as they will not, is producing a truly new sensor with a fundamentally new design on a smaller fabrication process size. It just isn't happening. If this thing is still a 500nm transistor part...I mean...WOW. That technology is about fifteen years old!! What is Canon doing? It's one thing to be conservative, but now it's just getting ludicrous...

I have always wondered about this, and you may be the guy to answer. Intel's next series of chips is what, 14nm process? I understand that Intel is purely in the microprocessor business, and Canon has to do a lot more than just optimize processes for sensors, but is there any practical reason why sensor transistors are / should be / need to be on such a different scale? Or is it just a matter of business and not wanting to make the necessary investment to keep shrinking? The fact that intel shrinks every other year has just made me wonder... because clearly there's an advantage to a smaller process.

cost.
no one creates large sensors using the latest technology - the A7R / D810E sensor for instance is on 180nm.  which is speculated to the be the same as the 70D sensor. D700, D4, etc were even on larger than that (350nm to 250nm)

the toshiba sensor uses 65nm and sony was looking at and just starting to use 90nm for it's APS-C sensors, but unless you're talking the smart phone / compact sensors - there's just no benefit to the smaller geometries over the cost of production with the pixel granularity where it is.

canon's current line of lithography systems can produce chips under 90nm - far exceeding even really what is required by sensors - so it's not as if canon can't if they feel they have to.  also to add to that, canon now has the equipment to product down to under 10nm geometries.

To be honest, people are humping on this as the core reason - not really.  and most of them don't have a freaking clue, but all of a sudden turn into electronic and chip designers (not to mention camera designers too).  canon certainly has a problem "downlevel" from the pixel - but their QE from their current 70D isn't that much off than the D5100's QE and even cutting the pixels in half they improved the QE by 10% over the 7D sensor level spec.

Your partly right, but your largely missing the point. A 500nm transistor is actually HUGE by todays standards. Think about it, that is half a micron. For a pixel that is surrounded by half-micron transistors, that is a FULL micron off all side of the pixel. A 4µm pixel is then only capable of, at most, a 3µm photodiode. The full size of the pixel itself is 1.78x larger in area than the photodiode. However, if you move to a 180nm process, your losing less than half a micron in total. That means the photodiode can be 3.6µm in size. The pixel is only 1.2x larger in area than the photodiode. Your photodiode area has increased by a factor of 1.5x, which reduces noise by 1.2x. That is significant. It's a stop gained in noise performance.

However, the REAL point about moving to a smaller transistor size is the ability to put more logic on the sensor die. At 500nm, Canon would have to make the sensor die itself quite a lot larger in order to move all the ADC logic onto the sensor itself, and make it column-parallel. At 180nm or better 90nm, they could move the ADCs on-die and need less than half, maybe less than one quarter, of the die space that would be necessary to do that with a 500nm process. Yield would remain high, so the cost of moving ADC onto the sensor would be much lower in the long run. THAT is the real point of moving to a smaller process. To allow more logic to be placed on the sensor die itself. The biggest gain there would be allowing full blown, high performance CP-ADC (and, maybe, also employ some of the other patents Canon has, such as dual scale ADC, power decoupling, etc.)

There is also a significantly greater per-pixel transistor requirement for stacked pixel designs. Canon recently released a patent for a five-layer sensor design. I honestly don't know how they would pull that off with a 500nm process. Not without a very low fill factor which would push noise levels sky high. However, with a 90nm fabrication process, creating a five layer sensor would be much, much easier, without running into serious problems with noise.

To add about 500nm vs 14 nm, I have read elsewhere (an article on Intel processors), that anything beyond 65nm is extremely difficult to produce and the yield is about 70% (which means 30% scrap in production, which in turn means very costly production, imagine if Canon had to scrap 30% of their sensors). The main obstacles are due to van der Waals forces - the force necessary to break the particle is larger than the force to clean it from a contamination for example (i.e. it is easier to break it than to clean it) and also the lytography is made with ultra-violet light and not with normal light, because the wave-length of the white light is comparable with the geometry of the particle at 14nm. The conclusion was that the efforts and costs to go down from 150nm to 90nm to 65nm to 25nm etc. is not a linear but geometrical progression and only 2-3 companies in the world can produce technology at 14nm. For example Intel is the only producer of processors at 14nm, their competitors are far behind.

PowerShot / Re: Canon Announces the PowerShot SX520 HS & SX400 HS

Don't worry, they'll come soon enough.  If you can't wait, feel free to switch to Nikon.  You might want to try 6D first for the meantime.  It's not as high-DR/MP as the D810 but it's the best Canon can offer if you're looking for IQ/MP.

I think I said I own a 1DX. Why would I want to downgrade? You may love the 6D, but it's already out of date.

My 1DX is very, very close to being out of date for the simple reason of Canon wishing to sustain their professional channels. This is their prerogative.

They could have a new high MP unit in the channels NOW. They could have an innovative mirrorless body in the channels NOW.

Instead, they announced new PowerShots? A lame cloud storage system? A partnership with MS? A new iteration of DPP?

You may be happy with these new announcements, and that is your right.

I am not.

For the record, 6D, 5D3 and 1DX isn't out of date.  Your skills will determine mostly if something is out of date or not.  And photography is not all about MP nor AF nor DR.  If you want the latest tech, maybe you should wait till photokina.  Who knows, Canon might make you happy, finally...

I have watched several videos from Joel Grimes and also a course of his on Creative Live, he is using Smart Object more or less as you descrive your workflow. Here is his blog

http://www.joelgrimesworkshops.com/Joel_Grimes_Photography/Welcome.html

there are some videos from him on YouTube too and you can also see this one, which is inspired by him as well

EOS Bodies / Re: Canon to Make a Big Splash at Photokina? [CR2]
« on: August 06, 2014, 02:21:28 AM »

That is the topic of maaaaany threads on this forum.  Does Canon really need 4+ APS-C body price points?  What about low/middle/high setup for APS-C and the same for FF?   What happened to APS-H?  What about a completely stripped down FF model with one AF point?

IMO, even six is probably too many.  They should have one consumer crop body and one pro crop body, plus one pro FF, and optionally one consumer FF.  Make the pro model(s) available in your choice of gripped or non-gripped form factors, but with otherwise identical guts.  There's just not enough product differentiation to support 6 or more bodies.  It drives up R&D costs without providing much customer benefit.

As ahsanford noted, we've been over this ground before, repeatedly.  The numbers just don't support such assertions, nor do the business strategies.  This is Canon we're talking about, not one of the <1% market share companies.  Product saturation is a successful, widely-used strategy for driving out competition when you have a large market share.  Canon is expanding their lines even while the market is contracting precisely to push small players out of the business completely.  Canon currently has eight DSLR lines running, plus one ILC, with three of those nine lines started since 2011.  Nikon has seven DSLR lines with substantially lower market share.

Instead of implying that every company is completely stupid, I recommend you reference the earlier discussions including the actual camera sales numbers if you need a clearer picture.  I've posted graphs in some.  You might also take a close look at the toothpaste section in your grocery store the next time you're there if you want a more concrete example of where the market is going and why.

Wow, I guess the new saying will not be "comparing apples and oranges", but "comparing DSLRs and toothpaste"  ;)
