EOS Bodies / Re: EOS 5D Mark III Replacement Talk [CR2]
« on: January 09, 2015, 03:57:51 PM »
It's getting to the point where everyone I know who shoots Canon has now switched over, or seriously thinking about switching over to Sony

Is your group a a statistical aberration, or are they representative of the entire market?

It kinda worries me a bit that some people aren't expecting those changes to take place.

I don't expect them to take place until the competition makes significant and consistent market gains against Canon. It's a mistake to think of the DSLR business as anything other than a business.

We’re told that the next EOS 5D will come in three different versions.
No matter which versions we will see, if Canon not dramatically improves their sensor IQ (see 7D Mk. II review on DP), they don't have to make these in the first place.
Why do you say so?  Canon has been more successful than Nikon or Sony despite their better low-ISO IQ.  Why do you believe The Market has changed?

It is not time for 5d4 yet. 5d3s yes.

It's time if/when Canon believes The Market requires it.

The light in photos #1, #3, and #4 are pretty amazing; and even as common as that wildebeest shot is in this contest, its still really impressive. And I love the negative space and colors in #16.

Which makes it weird to see photos #11 and #13. I guess I can see the playful irony in #11, but, it isnt capturing anything particularly interesting, and the composition isnt that strong. And #13...aside from being an interesting moment...has nothing going for it that I can see. The composition and light are boring, and I can't tell if its the lens or the aperture used, or maybe the focus is a little off, but the depth of field and sharpness isnt working. In comparison to #9, its night and day.

I like #1.

I don't find #3 very interesting at all: while the light is nice, the subject could easily be replaced with an animal or some other subject and suffer no loss of value. 

#4 has too much contrast -- it's manufactured drama where there is already real drama.

#11 reminds me of those "people of WalMart" galleries -- I have no patience for shaming or gawk value.

#13 reminds me of a Thomas Kinkade painting.

Many of them look over-processed to me...surreal, like bad HDR.

Will future generations of photographers (or other visual artists) recognize the era of these photos by the style of processing?

Canon is facing a total fail and too full of hubris to admit it.

I sold my 1DX and all my L primes. Not looking back. enjoy your PowerShots and shoulder killing full size units.

This is a classic logical fallacy(*): you're assuming that your needs/wants are representative of the overall market.  Canon, so far, seems to be better at catering to the overall market than its competitors.  I would love to see better tech in Canon gear, but until the competition steps up and takes away market share...

(*) This is a version of the Availability Heuristic/Fallacy, relying on a single data point (yourself), or a small set of data points (people you know or heard about) to extrapolate to the overall reality.  It's self-deceptive.

EOS Bodies / Re: Canon Confirms Development of High Megapixel Camera

So then my next question would be "Can Canon not employ a similar design?  Is such a design patented by Sony?"  "If they can, what's stopping them from doing this if a solution has already be discovered?  Would putting the ADC right on the chip be some radically expensive redesign?"


The real question is, why hasn't Canon employed technology they already own?

<snip>

Why aren't they employing this amazing technology in their consumer products? While Sony, which has many similar patents for many very similar technologies, IS employing it all, and continues to employ new innovations as they are made? Same thing goes for Samsung...similar patents, similar technologies, and they are employing those technologies in consumer products.

I think we can make a good guess at the answers to these questions: it's because they haven't had to.  It costs money to re-tool for innovative new tech, and that cuts into both profits and R&D.  Sony and Nikon have had to push out their best efforts to remain competitive; Samsung needs to put out their best to get into competition.

My hope (though not my rational expectation) is that Canon will push far enough ahead in their next retool to last for several iterations of the product cycle.  Maybe that's what will be at work with the new high-MP camera: the megapixel count could be an opportunity to take it out of competition with the 1-series so they can put in the new sensor tech.

Let's hope Sony, Nikon and Samsung put more pressure on Canon.

Happy New Year to all.  Go out and take some pictures!

The new line of lenses will probably be a total refresh of the lower end lenses, not the newest "L" lenses. 

They've already started doing that with the STM lenses.  If it's something he doesn't want to talk about, after having spilled about the high MP body, it's something fundamentally different.  What would be different enough to warrant a new "line?"  MF?  FF mirrorless?

I decided to go with Nikon...at least there is something there worth having

In what sense? What, specifically, is inadequate for your needs about the 5D3?

753mm?   ;D

FWC is dependent upon surface area...the surface area of the photodiode. With an FSI design, some of the pixel area is dedicated to wiring and transistors, which thus necessitates that the photodiode (the actual light-sensitive part of the silicon) become smaller. By flipping the die and etching on the back, the photodiodes can become larger, since the wiring is all on the other side. That increases FWC, which means for the same size sensor, with even the same size "pixel pitch", your actually gathering more light.

Thanks for the explanation.  For some reason, I'd thought the surface merely translated photos into electrons, but that the electrons were stored below the surface.

EOS Bodies / Re: Ron Martinsen Blasts the 7DII in his review
« on: December 21, 2014, 12:40:38 PM »
the incredible display of ego around the comment about his picture being the best a Canon sports shooter could expect from it . . .   Just a quick look around other reviews should have told him that others are not having the same difficulties he had and should have made him think again before hitting that publish button.

I think you've touched on the key here: so many photographers hold up their own personal experience (anecdotes) as examples of what can be done and what can't, what should be done and what should not, and forget that their personal experience may not match the experiences of others.  While personal taste is appropriate for the artistic component of photography, it's more an exercise in engineering to decide how to use the equipment to collect the most and best data from each click of the shutter.

Have to admit I was surprised that BSI is just now arriving at this level of sensor - my naivety - assumed it would have been here long ago.

My presumption was that gapless microlenses were supposed to make BSI unnecessary, but perhaps there's some marginal improvement using both.

Maybe one of our resident EE's can answer this question.
I think BSI more about increasing the full well capacity rather than just preventing light from seeping between pixels.

Hmmm...I'd like to hear more explanation of this: I had thought that fwc was not strongly dependent on the surface area.

Mr. Surapon,

Sometimes I think you should quit your day job and become a full-time inventor.  You might become a billionaire.  ;D
