EOS Bodies - For Stills / Re: Canon EOS-1D X DXOMark Sensor Scores
« on: October 13, 2012, 02:19:33 PM »
I mentioned this before, but perhaps it was lost in other conversation. My guess is that the 12.8 stops of DR for the 1D X is the "Print DR". It doesn't matter the camera, Canon, Nikon, or anyone else...I think that the Print DR figure is exceptionally misleading and falsely indicative of a sensor's capabilities. My guess is that the 1D X still only has 11.something stops of DR, like all the rest of Canon's cameras.

I would tend to agree there.  Having both the 1DX and the D4 (and I guess the D800), the only number in those DxO "rumored" scores that surprised me was the 12.8 DR.  Overall I do think the 1DX is a superior camera then the D4, however I still find from real life shooting that my D4 gives me more dynamic range when I shoot outside and I dont find the difference marginal either...

One of the biggest difference between both camera also seems to be metering which could explain in part my perceived preference for one camera over the other in certain shooting condition...

EOS Bodies / Re: Canon 5D3 vs. Nikon D600

Why is this surprising? Seems to me if you want low iso dr you go Nikon, if you want high iso performance you go canon.

I would tend to agree with your statement regarding the D800 for example, which i find unusable above ISO 1600 personally.  However, in terms of high ISO, the Nikon D4 is on par or slightly better then the 1DX.

Incidently, i find focus so slow on my D800 that when shooting at iso 100 indoors with a flash, i prefers the 1DX.  With the right lens it provides amazing result.  I did not expect topic here but thought i would share...

Well, I am drooling with this potential new camera.  If the DR is anything close to the promise, I would gladely sell back my D800.  I know many will complain that 46MP is not required for their work, but if this is the price to pay to get industry leading DR, sign me up!

 :P :P :P

... For example, I haven't heard very many wedding/event  togs wishing  for lower fps, worse AF, or higher MP, and I don't hear many complaints about the 5D3's IQ (including DR)  at ISO 3200

yeah not at ISO3200 at ISO3200 it has very good DR (only 1DX and D4 and D3s are better and the D3s is so much lower res it doesn't really count) it's at ISO100-200 or 400 where the DR is bad. The high iso DR on the 5D3 is better than any camera other than the 1DX and D4 basically.

+1.  Unfortunately shooting outside at ISO 100 even with the 1DX which I feel has the best Canon sensor, the Nikon D4 beats it if the scene has brights spots and shadows...  (I did not mention the D800 because that is not really a comparable camera but still...Canon is way behind here)...

Lots of interesting comment in this thread.  While I am not sure I would push it to a CEO stepping down, I am very disappointed with Canon strategy to strip down features in lower model like AF for example.  I much prefer Nikon approach as a consumer to offer as much as possible to each product.  I simply refuse to believe we need to pay $3k to get a decent Canon AF system now a days...

The second disappointment for me is the lack of improvements in their CMOS sensor compared to the competition (DR range for example, ability to pull and push shadows and highlights).   I have both Canon and Nikon gears, and when shooting in the sun outside, I am always frustrated at how Canon lack some DR for these typw of high contrast lighting settings.

That said, I think Canon is still king of the hilkl when it comes to lenses and their 61 pts AF system, but we need more then that now...

Very good read.  Thanks.

However this camera turns out, 5D3 owners will be burned.

For what reason? Unless you plan to buy another super computer for 46MP - raw file  ;D
I bought a D800, and my fairly powerful PC could not handle editing of the raw files without taking excessive time to render the images.  NR or other enhancements were painful.  I edited a 500 image shoot, and that was enough for me.  I've looked into the latest computers, but there is no major processing power improvements from my first generation i7 to the third one.  I need 5X or 10X better for a 40mp raw file that opens to a 200+ MB file once in a editor.

Sorry to ear that!  I have the latest Intel i7 six core processor and works fine with the D800 files.  They are a bit longer to process then the 1DX file, but not noticably.  If you use Lighroom, did you optimze its settings to leverage the full power of your computer (like your RAM, etc...).  I know Adobe have some article on that on their website...

It is not about the number of pixels but the quality of the pixels that put the D800 spreading like wild fire in the market place! Nikon has created a new niche this time ... I hope Canon don't miss the boat, this round!
The credit goes to Sony, who developed the Nikon D800(E) image sensor. This Sony-Nikon agreement will soon allow the same technology will become available to others.
The big difference in shooting a D800 versus any other FF camera is the D800's depth of detail which eliminates the need to frame tightly using a fuzzy zoom lens and instead allows shooting wider frames with the very best primes. The post cropped image then offers the very best in both detail depth and lens sharpness.
Unfortunately the Nikon D800 focusing problems are taking the edge off Nikon's success with the D800.
Sony themselves, Leica and Hasselblad are jumping on the bandwagon and are also likely to reap great benefits from this Sony high MP technology.

I agree.  Sometime I am amazed of what I can find cropping the D800 image taken with a 35mm lens for example.  Almost like an image within an image.  I get the wide angle view and can crop to zoom equivalent on the face to create close up from the same file.  On a few occasion it allowed me a great close-up I could not have done so...

Personally I love these specs and I would get such a camera.  Having played around with a D800 a bit I could really dig a high MP camera with Canon with great ISO 100 performance (aka industry leading DR) to complement the 1DX.

I hope they make it happen.  Not sure how such a camera could be priced below $4k though...

as a very happy user, my simple answer is YES!

1- 50L f1.2
2- 85L f1.2 II
3- 70-200L f2.8 IS II

This may surprise many but my favorite is by far the 50 1.2.  At least this is the one I use the most for indoor shooting.  I shoot both Canon and Nikon now, but I find there is no NIkon equivalent to the first two above.  The two f1.2 from Canon are in a class of their own...

EOS Bodies - For Stills / Re: 1DX ISO 12,800 real-life test
« on: August 06, 2012, 08:42:51 AM »
quite wonderful.  what shutter speed and aperture did you use?  Just curious to know a sense of the amount of light present...

Recently on a vacation trip I surprised myself taking a few ISO 16,000 shots of my daughter playing.  I included those shots in a printed book I did of the vacation pictures, and you cant tell which ones are the actual 16,000 ISO shots!  Quite nice!

There are quite a number of other differences between the 1DX and the 5DIII, but none of them are any more significant to real-world shooting than the noise difference we see here.

Depends on your definition - if you're talking only IQ, fine.  But...better sealing and 250K more shutter actuations seem like they benefit real world shooting, not to mention the improved metering.

The new metering in the 1DX has really impressed me so far.  I still have a D4 lying around and over the week-end I played taking the same shot with both the D4 and then the 1DX (inside shooting) - not a real test but just real life shooting... There is no doubt that both metering system are "tuned" differently.  However all the "WOW" pictures I got were from the 1DX.  Not only is White Balance much improved from the 5dmkII but there is just something about how the 1DX capture light and adjust the exposure to make some spectacular shots.  In comparison the Nikon metering seem to produce more flat pictures...still very good...

My point was not to make this comments about Canon versus Nikon metering, but just using reference points I have/know since I cant compare with the 5D mkIII...

Ok. more megapixels. That was always going to happen.

But will the sensor be any better?
Will it still have vertical banding up the wazoo in dark areas?
Will the read noise be the same?
Will the dynamic response be about the same?

What was so good about the D800 wasn't just the increase in number of pixels but the quality of those pixels.

+1 !

I really hope a new high MP body will also come with much improved dynamic range.  If not then I have no interest.  Shooting with both the 1DX and the D800, I am just amazed at the dynamic range of the D800.  It really DOES make a difference in several shooting conditions, like outside in the sun, inside when a window is in the composition, etc.

I never thought I cared about DR until I tried the D800.  Now when lighting is perfect, it is still no match for the 1DX to my personal taste :-), but then again those are two very different cameras...
