The single most beneficial aspect of Zone AF is that it will focus on the closest part of the subject.  Even in 61pt you have to get AF using the center point first.  If that happens to be a tail on the far side then AF will track that point and not the head.  There are tradoffs going either way.

Expansion will af on whatever the center is pointed at and the surrounding points will be used to assist AF if the center loses the subject.

The main diff is that Zone will always try to focus on the closest thing in the zones range.

@Cervantes: Did you ever try to shoot birds or any kind of sport with AF Expansion mode including 4 or 8 additional surrounding points? I never know which mode is better - Zone or AF Expansion. Can you tell why AF Expension mode would not be appropriate for birds or sports?

Otherwise, very good and informative article!

Great article, especially the undocumented features.  I need to try this but theoretically if you enable orientation linked af point you should also be able to set independent af-on settings for portrait or landscape mode...that is have two selectable zone af points in portrait mode and zone af and 61pt in landscape mode.

Another recommendation is to leave af case mode 1-5 in their default state and use the last case mode 6 for your customized bif settings. 

And you can further customize your use modes by recording your ideal BIF fast action settings to custom mode 3 at the end of the mode dial.  This will let you switch to this mode quickly without looking and will also save all of your customized settings....one may actually want to use different af and af-on settings for shooting a wedding or portraits or even bif with a different lens.

Pretty much the configurability has endless combinations and even more headspinning combos on the 1dx.  Its important to use the settings that work for you and then save them to a custom mode or you may spend a lot of time reconfiguring every time you change shooting environments.

11.6 Analysis at Both Ends of a Zoom Lens

The FoCal Manual Mode test can run two sets of analysis within the data captured for different lens focal length. To use this feature, simply supply shots taken at a spread of AF Microadjustment/Fine Tune values at two different focal lengths and select all the images into the test – the software will analyse the files, group into focal lengths and produce the results as shown:
In FoCal Pro, the vertical lines on the chart indicate the focal length that the result applies to. For all versions, the Predicted Best indicator will show two values for the tested focal length – in the example above, 40mm has a best AF Microadjustment value of -2 and 17mm has a best value of -7. Standard practice for zooms on cameras with single AF Microadjustment values is to bias the single programmed value towards the telephoto end, so in this instance a value of -4 would be best to enter into the camera for general shooting.

Though you may be better off using -7 as the dof is so wide at 17 that the difference between -2 and -4 wouldn't be noticeable.  -7 to -4 at the tele end would almost certainly be noticeable.  The best thing to do is to try it and see what your results show.

So is it really possible to downgrade a 5d3 from 1.2.3 to the required 1.1.3?  The 1.2.3 fw docs state that it is not possible to revert back.

And now I have bought it!!

Just needed to tell someone before I expload from the inside of excitement! =)

I hope I can get it at the store this Thursday or Friday. Also bought a 1,4 converter and a Lowepro Lens trekker AW II. This weekend I will also order a RRS TVC-34L, Wimberley gimbal head, RRS lens foot and some other stuff.

Broke but happy =)

Thank you all for your advices.

Good job, depending on the actual definition of "broke". I would never want to put myself in a position where I actually have nothing in the bank, but spending leftover cash is a good feeling.

Right now I'm debating between getting a new car, or a nice used car with leftovers going to a big white. I really have no need for any of it, but those who are good at saving get to have these problems.

Go with a used car and a big white.  A new car doesnt get you much but a loss of thousands as soon as youndrive it off the lot.  Put that money toward a good lens.  There really is no other logical choice in the matter.

1Dx
600mm
 here is a couple more BIF's shot two 8 shot burst's trying out the new1dx update I was shooting on AV  but my iso & f stop  was moving on me so I need to go look at my settings  to see what I need to turn off.

The buck obviously didnt like the 1dx machine gun fire.  Rat tat tat tat tat.  ;)

EOS Bodies / Re: "Honey, I'vs never seen it this hard before..."
« on: January 27, 2014, 06:58:34 PM »
honestly if someone is unable to make good photos or videos with any of todays cameras it´s not the cameras fault.

I agree with you on this.  Ive used my 5diii with a 24-70 f2.8l to shoot portraits by campfire hand held.  Certainly most people should be able to use even a rebel to shoot good shots of the family by even marginal interior lighting.  What makes the high end cameras stand out is there ability to catch action such as sports (1dx) or catch portraits of brides and bridesmaids in Whisper quite mode (5diii).  If you dont shoot in either of those environments you can do quite well with any newer canon body at f4 or faster.

Once you get a taste of Canon sweetness though its hard to go back.  Seems like this is a case of sellers remorse.

Lenses / Re: Should I go for the 85mm F1.2L II USM ?
« on: January 26, 2014, 11:30:27 AM »
Thanks guys  :) I went for it and I just received it a week ago and can't mount it OFF my 5D III. I had it for 1799 $  .. in general I like everything about it from crisp shots and awesome creamy BOKEH oh my god the bokeh is totally worth it  ::) but what concerns me the most is the rear glass of the lens ..  it's too exposed unlike my other lenses and can get all the dust just by switching lenses, and the autofocus is a bit slow when shooting in F1.2 where the lens tries to spot on a focus point, all in all it's a queen of glass and can be used in a fight when needed  ;D

Actually the rear glass being exposed is a plus.  It is flourine coated and easy to get to.  Just wipe with a lens cloth or blower and it's clean.  The flourine coating is extremely durable.  Just when you are in fight, try not to hit the sap with the rear of the lens.  It should be fine.

Just get the 5diii.  You get a LOT more than just more cross type af points.  You can run the iso easily up to 3200 and probably still never need to go below f4 in your apartment.

Im not even sure why you are even asking this since you already owned one and know what its capable of.  If you want a point and shoot to photograph the kids then buy a powershot or an M.

Breakthrough at Magic Lantern, imho this elevates it to a must-have and makes Canon look really stupid: They at last figured out what the digic registers having to do with iso are, and by fine-tuning them your camera now gets an additional 1/2 stop and more of dynamic range, no strings attached. Just use +1/2 stop of ec (ML also has ec in m mode, just like the new 1dx fw) and you're done.

This means that for example on 5d3, iso 800 with ML has more dynamic range than iso 100 with Canon :-> ... and at high iso you're getting 7% more dr which is nothing to sneeze at, esp. since it builds upon Canon's advantage vs. Nikon: d800@6400 = ~8.3 & 5d3@6400 = ~9.4 ev making good ol' Canon the superior sensor for low light high contrast shooting, esp. the newer 6d.

Code: [Select]
5D3 Canon ML
100 11.16 11.55
200 11.08 11.52
400 10.96 11.41
800 10.76 11.2
1600 10.32 10.78
3200 9.72 10.2
6400 8.78 9.35
12800 8.01 8.59

Read all about it here, test modules are about to be out, next coming to a nightly build near you! Here's the dev thread if you want to follow the development: http://www.magiclantern.fm/forum/index.php?topic=9867.msg96529#msg96529

Last not least, in combination with the dual_iso module ML now allows you to cover 15 stops of dynamic range in one shot w/o bracketing (by interlacing the shot with two iso values, meaning there's some loss of fine detail in the extreme highlights/shadows). If you feel exposure challenged, you can use the ettr module to automatically set the exposure so it covers exactly the dynamic range of the scene with optimum snr :-)

Great report.  I havent had a chance to try any of this.  Wonderiing what effect all of this has on drive mode frame rates?

EOS-M / Re: My full gear in sling pack with EOS-M
« on: January 20, 2014, 05:26:10 PM »
This is a very nice bag for the M.  I like small bags.  I carry my 300mm F2.8L and my 5D3 in a bag that doesnt even look like it can hold that set up.  Everyone is amazed when I pull out the big rig from my Streetwalker Pro. 
 
This for the M looks  very similar.  Very low profile...doesnt look like you are a pro photographer with expensive gear to target and steal.  Small enough to just leave on your back all the time.
 
I do miss the fast focus though.  Live view focus is too slow for ANY kind of action.  However is pretty easy to just use manual and go with it.

EOS-M / Re: GREAT AND CHEAP BATTERIES FOR EOS-M
« on: January 20, 2014, 05:20:54 PM »
These cheap batteries keep calling my name ... but I resist..waiting for more feedback from users here to report on accurate battery level display and total shot count.  Also would like to hear about how hot the battery gets when fully charged...and perhaps how hot it gets after a good shoot.

As mentioned previously there is a good reason usually why they are cheap.  I am willing to live with short battery life for such a price but not really interested if it takes the camera with it.

Same setup.  Actually very light weight rig with the 100L attached.  You can still hand hold it with the grip.  Not too front heavy.  Next time I will try with my extension tubes.

Software & Accessories / Re: Adobe Lightroom for iPad Coming Soon
« on: January 19, 2014, 10:50:11 AM »
I can't say I'm too optimistic about the processing capabilities of the iPad. Let's remember that LR is meant for batch processing.
True ... but iPads/tablets, with each new version will only get more powerful and better ... eventually we should be able to have some powerful processing power from these portable devices. This is just the beginning.

I'd rather have an app to connect the iPad to a computer and use it as second screen. The one thing I like is the pixel density, useful for the determination of critical focus.

Check out air display 2. One of many out there.
