from a few pages back:

@PBD likes to make points demonstrating with his 1DS 3 but he is, in a way, CHEATING.
Not because of misdirection with his example, but because the 1ds3 is likely the best FF camera, IQ-wise, that Canon's ever made.

It has the best color response I know of, other than the 1000D
It has marginally better dynamic range than most other Canon's.
But, IMO, most importantly, it was PRE-Digic 4!
the FPN issues became a serious problem AFTER digic 3

PBD, you can't make those same examples as effectively with a 5d2, 5d3 or 1dx.
FPN read noise issues are worse with Digic 4 and Digic 5 than they were with the old Digic 3.

You don't see me making bad stripey noise examples with my 40D by pushing shadows.. because it doesn't have the same level of read noise banding problems bodies like the 7D have.
And that's why my 40D is still in my stable, it works, it's cleaner than subsequent models from Canon up until the 70D, and hopefully the 7d2.

Shamefully unfair comparisons.  new cameras do not perform as well as those older ones.

810 doesn't just approach the 5d3, in tech, it pulls out and passes it and flips the bird at it on the way by.

Yes, we all know you think "camera" = "sensor".   Frame rate...5DIII > D810.  AF system...5DIII > D810.
Hmmm, plus:

Canon Lenses > Nikon Lenses, ML at Canon > ML at Nikon .... ohhhhh wait  :o

Why do you say that out of curiosity?  Don't get me wrong, I'm somebody who almost went the Nikon route but ultimately went with Cannon, however I keep running across assessments that Nikon and Cannon both have excellent and nearly equivalent quality (overall) lens offerings.

There are a few things that Cannon offers that Nikon doesn't (ie: I get the impression that Cannon is better when it comes to macro offerings) and visa versa (Nikon has traditionally had more to offer with Wide Angle lenses... particularly UWA zooms).
Maybe for reasons like this:




Bryan's good at buying 4 of 5 iterations of a Canon lens and keeping the best one. I doubt he does that with his Nikon kit.
I had said Canon lens and mine had far more CA in the FF corners than this demo
I have the 70-200/4vr Nikon lens and it renders vast amounts of detail to a d800e without any significant CA.
The point is, almost all the lenses these days are damn good and there can be more variation within items of the same model than between mfrs at times.
I don't have any Nik lenses I can complain about, I chose wisely.

5D Mark III got the job done.  I'm happy with my choice of "tools".
Mustang Sunrise Photo Tour CCA 2014 Sun1099 © Keith Breazeal by Keith Breazeal Photography, on Flickr

Keith, those are some nice images but I'm gonna be tough on you here.  Even to my old eyes the shadow tones in the mustang shot look full of canon chroma noise and stripes.  Not in this little dinky downscaled shot within this thread, but the 2 & 3MP "large" version available on flikr.
And they are, you don't even have to push anything to see it, just look between the 2 photog's on the R side.

Sorry, tools like that do not meet my standards of image quality, not when they come with that kind of price tag.
If you're happy with them, great.  But image quality like this is the reason I dumped Canon and went to ABC cameras.
Most people likely would not notice the noise, I sure do, much as I listen to the silence between the music.

A crop and 2x linear with some gamma shift to make it obvious for those who can't see it in the original.
Maybe I'm just getting spoiled looking at super clean ABC shadow tones for the last couple years, this now jumps out at me in some shots.

EDIT:  typos fixed, minor change in wording

Photography Technique / Re: Why 3:2 aspect ratio?
« on: September 26, 2014, 06:30:54 PM »
I like 3x2 and 2x3 for lots of landscape and natural images.
the 4x5 ratio looks good for many portraits and other images I will crop to what best suits the overall image balance.

There's a very limited edition skyline panorama I've done that didn't look quite right at 36x12"
Changed it to 36 x 11.25 and viola!  masterpiece!
Sometimes it can be that subtle.

MIDTONE banding with gray fog and blue skies are where i first noticed problems with Canon images when I had my 5d2, ages ago.
Shadow pushing landscapes with every Digic 4 body showed me the FPN issues in shadows.
Quick testing of my 5d2 showed me that FPN was readily visible in smooth shades only 2 or 3 EV below metered middle if pushed only +1 stop.
I still maintain it was the most disappointing body I ever had, and possibly a lemon but... there were more of them out there like that.

I'm feeling somewhat vindicated by so many more of you, some who've previously argued against these very observations, corroborating this problem.
My only question is, WTH took so long for some users of same equipment to notice this?!?  ???

EDIT:  To answer PBD, you probably could push the 70D files by 3 stops and not be bothered by FPN but you'd still have plenty of shot nose to get rid of and that will eat some of the detail in NR software.  the 7d2 might perform similarly.  the 6D would get away with it in some shots, as will the 60D as I've done it for some shots with acceptable results. Other digic 4 bodies, not likely as capable.  older digic 2 and 3 bodies would behave a bit like the 70D and allow a good push in many cases but would have even greater overall noise levels to deal with.

..I am now finding that they all have their respective uses for what I do. While I understand that it is not necessary to have all of it to get the job done, it is nice to have the option of choosing the best tool for the job when needed..

They're all similar, but different and each have their uses.
sez the guy using Nikon F, Canon EF/S, Pentax K & Q, Fuji X, MFT + a pile of fixed lens compacts.  No MF, Sony or Samsung for me yet.

Sporgon - nice shot, but I can't actually tell noise levels in a 0.37 MP image. Also, I prefer not to have horizons that blown, but that's just me.

could've retained more color near the horizon by reducing exposure and bring up the rest a bit more IF you had shot that with an Exmor.  Not that you HAVE to, it would just provide you with that option, should you choose to use it.

Canon General / Re: DRones vs. anti-DRones: how to resolve the controversy
« on: September 25, 2014, 11:45:26 PM »
..Unless you shoot Nikon, at which point Nikon shooters will argue that 36MP is more than enough and existing DR is plenty, and DXOmark favor Canon.

Well, I can already say my d800s are good enough that I can easily sit out a generation or three of body updates. They provide adequate performance for how I want to use them.
If the rumored organic sensor comes out from the Panasonic-Fuji collaboration that will be interesting.
And I'm looking forward to trying the 7d2 and it's funky new AF system.  Speaking of which, the DP AF should be a feature on the hi-rez metering sensor as well, that could REALLY help with the AF performance.

EOS Bodies / Re: Canon Says Higher Resolution Sensors Are Coming Soon

Sure, I don't disagree with that. However, to outright state that their camera sensors are the best on the market is taking it too far. There are many other words and phrases that could be used to describe Canon sensors and still give Canon customers the sense that Canon is working to improve things. But to outright state that they don't know what measurements could possibly be indicating their sensors are lacking in the dynamic range department, or to outright state that their sensors are the best in the world...that's insane.

Especially when so many customers in the market KNOW it's a bold faced lie. Because that's exactly what it was...a bold faced lie. :P

HAHA!  reminds me of another camera maker saying something like, "What are you talking about?  There's no dust or oil spot issue with our camera."

This is like politics, they have to tell the not-truth enough so that (many) people will (continue to) believe it.
it would NOT be good for stock price for Canon to admit their sensors are in any way behind in any performance metric.
It's all about the money, first.  product and customers are secondary, even if they do have great service.
That said, I'm looking fwd to trying the 7d2, even if it's not quite as good, IQ-wise, as my micro-four-thirds.  As long as the FPN is gone, i can use it.

Edit: well, IQ-wise I still prefer the bigger pixels from my 60D than from my MFT as the also larger long Canon lens I use with it outperforms the tiny miracle on my MFT.  But the noise metrics on the MFT are obviously better.

Just for kicks, I'm attaching a photo from years past.  Biked to the top of Castle Craig in CT, US and took out my first digital camera - the Canon G3 to take a shot.  Unfortunately I knew nothing about RAW back then...
Nice shot.
Canon G3 is a great old brick!  Very nice jpgs so little need of raw.  I still have a bunch of old G3/5/6 bodies and occasionally use them still.

I'm talking about normalized Raw performance, which has seen very, very small gains. Save for at the highest ISOs (e.g. 25.6k and above), where lowering sensor-level (upstream) read noise actually affects image quality, since you're amplifying the raw signal off the sensor so much (b/c the signal is so, so small).

Otherwise, ISO performance is largely dictated by sensor size these days.

I'd like to throw an orange into this nice comparison of apples.  A nice tasty tangerine of a sensor.

I was curious about comparing Canon's best-to-date crop sensor, the 70D (until we know what the 7d2 can do) so had a look at DxOmark's data on it and compared it to a sensor with 2-thirds the surface area. (OMD EM10)

I thought that the larger surface area and decent hi ISO performance of the 70D might actually have an edge in hi ISO performance.... BUT I WAS WRONG. ;)

The tiny MFT sensor of the Olympus EM10 completely smokes the 70d in SNR at every ISO and every signal level.
So, despite the physics advantages of larger sensors, comparing the performance means you do have to consider the underlying technology used to collect the data from those sensors.

The ~220 sq mm of the MFT sensor outperforms the ~330 sq mm of the Canon 70D at all ISO.

(no wonder I'm enjoying the little snapper! :) )

Now I am really hoping the 7d2 sensor can perform at least as good as my micro-four-thirds sensor.  Then the 7d2's advanced AF system and other benefits will be better appreciated.

Some allusion to MFT size sensor there, as well, it seems.
When I consider just how good the IQ is from my Oly EM10's tiny sensor, with just enough ability for OOF areas and DoF control, it seems like the 4/3 system was well conceived for all around compromises.
I can landscape at low ISO with some shadow push ability, use iso25600 and get usable images for small prints, put on a long lens for shallow DoF shooting, all in a tiny light package.
Yup, that sensor size is a good compromise.

You're kidding me!!!  :o
Why not in the US?  :'(

Dunno... we're closer to Santa Claus?..

I'm thinking I get to test drive a 7d2 and 24-70/4 L lens then sell it off for a profit on eBay. :}

The 24-70 will be cheaper than their new standard zoom  :o
AND I get to keep the jacket!  ;)

Don't tell me you're not planning on putting those amazing skins on all your iPhones and iPads.
But seriously, great deal...
HAHA!  No iPhone, no iPad, never will. Hate those things and how iOS works.
Doubt it would fit my 10" Asus tab .

And, pre-order was placed earlier this week so will now wait and see what the 7d2 can do for me.
