EOS Bodies - For Stills / Re: 1Dx simple DR stress test
« on: October 19, 2012, 09:32:43 AM »
I'm tired of your patronizing comments, see photos above.and show me one example of what you can do with a Canon and not with a Nikon except shooting faster

I'm tired of you reposting the same or equivalent shots in thread after thread after thread.  Nikon/Sony sensors have better DR than Canon sensors.  If your point in reposting the same statements and images in every thread that even tangentially mentions DR is to convince members of this forum that Nikon/Sony sensors have better DR than Canon sensors, you can stop - we get it, and we got it before you started posting here.  If your point is to induce Canon to produce sensors with better DR, this is not the place for that effort, not to mention that I'm sure Canon knows the DR of their sensors, know the DR of Sony/Nikon sensors, and has chosen to emphasize other design priorities to this point.

Is DR the only thing that matters to you when taking a picture?  To me, it's not.  If my 'once-in-a-lifetime shot' was a black barbeque against the side of a white shed in full sunlight, then my answer might be different.

When I said that I, personally, can get images from my Canon camera that I could not get from a Nikon camera, did you jump to the erroneous conclusion that I am also saying the converse?  One could certainly get images from a Nikon camera that one could not get from a Canon camera.

Instead of test images manipulated to repeatedly argue the same point, which has already been conceeded, let me remind you that taking pictures is about far more than the sensor inside the camera, and leave you with the following rhetorical questions:  Where is Nikon's MP-E 65mm?  Where is Nikon's 600mm f/4 lens which is light enough that I can carry it for a 5 km hike then use it to take a handheld shot?

EOS 5D Mark II, MP-E 65mm f/2.8 1-5x Macro @ 5x, 1/60 s, f/11, ISO 400, MT-24EX

EOS 1D X, EF 600mm f/4L IS II + EF 1.4x III Extender, 1/640 s, f/5.6, ISO 100

EDIT: I have come to the conclusion that your primary purpose here on CR seems to be agitating and formenting rancor, the bold-face edits to your post above after I hit the quote button clearly show that, as do your 150 posts with something like 90% of them beating exactly the same dead horse.

Why  must and should we exposure Canon richer= longer exposure time and even then get a poorer results in the shadows compared to Nikon.

We must, because last time I checked, sensors do not take pictures.  Cameras take pictures.  Sure, you can manipulate images and identify differences in sensor performance.  But the fact remains that I (and I mean me, personally) can get images from my Canon camera that would be impossible for me to get with a Nikon or Sony.

Ok, say there's no difference inside at all, other than the one port we know about.  That means Canon is charging a 91% premium for code that offers critical features for a certain group of users.  Why are people up in arms about this?  Adobe is charging a premium for Photoshop CS6 vs. Elememts, for the same thing, code that offers critical features for a certain group of users. But, Adobe is charging a 459% for their code.  ;)

From these figures, it looks like I can get more than 1:1 magnification with my 70-200 @70mm.  Or do I only get a 0.21x baseline magnification factor at 200mm?

The 0.21x max mag value for the 70-200 applies at 200mm, it's lower at 70mm, which is where your tubes are more effective.

A 70-200/2.8 II @ 200mm with a 2x TC behind it and a 500D in front gets you 1.2x mag.

EOS Bodies / Re: Canon EOS-1D X Firmware 1.1.1 Now Available

To those who have updated to 1.1.1, does the camera keep all your custom settings or do you have to change them all back to how you want them after upgrading. (or maybe you did an export/import of your settings first?)

All the custom settings are retained after the FW update.

Assuming money was no object, a 1D X with a 600mm f/4 L II IS and a pair of Mark III TC's is definitely the way to go. I don't think money can currently buy a better set of gear for a nature fan.

There was some focus hunting when shooting birds in dense foliage with backlighting

Here's a shot that shows the bird and surround, a tough job for any AF system.  This was with phase AF, and I haven't done an AFMA yet (need to find a deserted football field for that!).  Might be a little back-focused, I think.

Shot is with the 1D X and 600mm f/4L IS II + 2xIII, 1/320 s, f/8, ISO 4000.  Original and a 100% crop to show detail, which is quite good, IMO.

Well, I guess this all changes for 1D X owners with the issue of the upgrade 1.1.1.  I have made the upgrade and now all I have to do is test it out and see what happens.

Worked decently today with the 600 II and 2xIII.  There was some focus hunting when shooting birds in dense foliage with backlighting, and I thought, hmmmm, is this because of the 2x?  So I switched to the 1.4xIII, and the hunting was no different.  It was a bit better with the bare lens, but still not perfect.  When I moved to a different angle that eliminated the backlighting, it was fine.

Lenses / Re: Canon 70-200 f2.8L IS vs Canon 70-200 f2.8L IS II

So, the 70-200 f2.8L (non IS) is sharper than the version 1 IS right? I was checking that 'lens resolution charts' from digital picture labsite and I was surprised that non-IS appears to be sharper than then the version 1 IS. I didnt want to believe it. Any idea if the f2.8 non-IS takes a big hit when extenders are used on them?

Correct.  The non-IS takes a bigger hit from the extenders than the MkII. 

Honestly, if you have the budget and don't mind the weight/size, the 70-200 II is pretty much the best telezoom lens available today.

The original f/2.8 IS is the least sharp of the f/2.8's, and also not as sharp as the f/4 IS.  The MkII is the sharpest of the 70-200's.  The difference between the MkI and MkII is real, but not huge. mention wildlife.  If you ever plan to put a 1.4x or 2x extender behind the 70-200, get the MkII - no question. The original takes a big IQ hit from a 1.4x and a very big hit from the 2x. The MkII with the 2x is almost as good as the 100-400's native 400mm.

I think that's a bit cynical.

Clearly, you know me well...   ;)

FWIW, the shutter speed range on the 1D X is 1-stop increments, not 1/3.

I have done the comparison as well. Comparing the 7d to the 5d II image cropped to match, the amount of improvement you gain with the  7d is marginal. If you have no PP skills it is non existent as the 5d II will be better.  To make the 7d file marginally better requires more processing than the 5d II. The difference is not enough to matter.

The difference that does matter is the AF system of the 7D and the high frame rate which makes it a better wildlife camera.


I'd take the 7D over the 5DII for birds/wildlife/sports.  But compared to the 7D, the 5DIII has better AF, much better high ISO M, and gives up just 2 fps.

When I got my 5DII, I kept my 7D for birds/wildlife. After getting the 1D X, I sold the 5DII.  Now, I'm not sure I will keep the 7D...the IQ is no where near the 7D, and with the new 1D X firmware I can now AF at 1200mm... 

Outside of a backup body, why keep the 7D?

Canon would say, "Buy a 1D X, and you can set a minimum shutter speed from 30 s to 1/4000 s."

The "blinking" on mine is refocusing... each time it achieves focus it "blinks", which for AI Servo is all the time if you're moving at all... which is what it's supposed to do... I'm coming off of 2 1/2 years with 7Ds so this function turned off works for me... I might try it for night football but...

Not sure that's the whole story - it blinks when focusing with the lens cap on, and in that case it's clearly never achieving focus.

I've compared 5DII cropped to APS-C framing to 7D, and found the IQ to be a wash. With minimal processing, the 7D had more sharpness/detail, and the cropped 5DII had less noise.  Noise can be traded for sharpness, of course. The main difference is that the 7D is 18 MP while the cropped 5DII is 8 MP - fine for web and small prints, less desirable for large prints.

Still - I'd not recommend the 5DII for birds/wildlife due to the AF.  The 5DIII is a different story.

An APS-C sensor vs. FF is sometimes called a 'perfect teleconverter'. But that's theory - generic APS-C vs. generic FF.  I have directly compared my 7D with 100-400mm to my 1D X with a 1.4xIII behind the same lens, and at ISO 100, there's no real IQ difference, while at ISO 3200 the 1D X with TC is clearly better.
