EOS Bodies - For Stills / Re: 5D Mark III focus points off center
« on: May 15, 2013, 02:09:37 PM »Yes but it sounds like he is comparing the viewfinder square with what is displayed on the LCD screen on the back. They are two different things not linked together...at least not on the 5D3.
The red AF point markers on the rear LCD are not tied to the point in the viewfinder...though they attempt to show you which AF point was activated during the shot, they are not calibrated to the PD sensor.
So if I mount the body on a tripod, live view and viewfinder focus on different spots even when both for example use the middle AF point? Is that what you are saying, or is one of them just indicating a false AF point position? The middle points are not on the same targets.
The sensor remains in the same spot, framing is therefore the same. I doubt that these two modes have separate AF systems with different AF point locations.
Someone correct me if I'm wrong, but I believe that liveview focusing doesn't use auto focus points at all. The autofocus points are used only for phase detection autofocus, while liveview focusing does contrast detection by actually reading the data off of the sensor itself, rather than making use of the autofocus array.

Check out the packs from f-stop (http://fstopgear.com/product/mountain/satori-exp). They are modular, allowing you to carry both camera equipment and other things (clothes, water, etc...) in the same pack. I took one (the loka model) on a 2 week trek through Peru, worked great.

EOS Bodies - For Stills / Re: Speeding AF point selection on 5d Mark III
« on: March 24, 2013, 05:48:34 PM »
I've also found getting used to this to be difficult. In particular, I find that when trying to move a number of points to the lleft, I often times end up pressing in the multi controller in (resetting the focus point back to the center one). I'm getting better at not doing this, but still happens quite often. Being able to hold it in (ala joystick) would be great

Software & Accessories / Re: 1d X "silent" mode.
« on: March 12, 2013, 12:23:00 PM »So in theory, mirror locked up, live view shooting could be a kind of silent mode?
Yes, Live View is quieter than regular shooting. It also uses an electronic first curtain shutter and that eliminates another source of vibration - that makes Live View ideal for tripod-mounted shooting of static subjects.
Is this true (electronic first curtain) for other camera models as well (E.g. 5d3), or just the 1dx?

EOS Bodies - For Stills / Re: Mark III manual mode-changing ISO speed, its not changing the exposure meter bar
« on: March 08, 2013, 06:00:35 AM »
I also found this really annoying when I first got my mk3. Best solution I have found is to change the 'set' button to control ISO, then when you hold in the 'set' button and turn the control dial, you will see the meter change as the ISO changes.

If you are using Lightroom try turning off lens corrections, I noticed something similar at high iso with a 50mm.

EOS Bodies - For Stills / Re: 5d3 and FoCal errors
« on: January 25, 2013, 04:17:35 PM »
Well, I finally figured out my FoCal issues w/the 5d3. It's snowing here in the Baltimore area and that gave me a bit of down time to spend playing with it. Hopefully this will help others out if they are having a similar problem.
It seems that FoCal will not perform the phase detect autofocus step if the AF-ON button is not configured to "Metering and AF start". I had mine set to AE lock (hold).
I've e-mailed their support, and hopefully this will be added to the configuration changes the program makes before it runs it's tests.

EOS Bodies - For Stills / Re: 5d3 and FoCal errors
« on: January 04, 2013, 09:21:55 AM »I bought it when it first came out a year ago, and each new version has worked better than the previous. Sure, there are a few minor bugs, but most of the time, the issues have been mine.
Correct setup, plenty of bright light, absolutely no vibration or movement, concrete floor is far better than a wooden one.
Some lenses are problem lenses, they just do not perform repeatedly or well. In some cases, its the lens design, the cheap 50mm lenses are never going to do well. The "L" lenses do very well.
I've found that the 5D MK III gives much better results than my 5D MK II's did, and that is borne out by the data sent in from testers.
If your setup is perfect - stable, bright light, viewfinder blocked, firm floor with no vibration, accurate target alignment, then AF issues are likely a problem camera or problem lens. Both can be problems, we just never had a way to test before.
Overall, it works well and is repeatable for me, but the devil is in the details of a good setup.
As far as computer issues, I've had none on my Lenovo Windows 7 64 bit laptop or old Dell XPS-420 desktop that was upgraded to Windows 7 64 bit. Having a lot of older equipment increases the probability of drivers conflicting, or software conflicts. Those just have to be worked thru, there is a infinite number of combinations of hardware and software, so no amount of testing will guarantee that it works for everyone. I'm now in the process of testing out my new Dell XPS 8500 with Windows 8 64 bit. FoCal is installed and running fine, but I've not done a full AFMA using it. I most likely will not in the near future.
I'm sure it's something I'm doing wrong, but I just can't get it to do anything.
I've tried 2 computers (windows xp (32 bit), and windows 7 (64bit)), 3 versions of FoCal (1.6, 1.7 beta, and 1.7 released). All shot with the camera on a tripod, on wood floors, in light levels from (1/25 f/2.8 iso 100 (the recommended value in the FoCal docs) up to 1/1250 f/2.8 iso 100). I've tried several lenses, various zoom settings and target distances, all with no luck. The software simply refuses to even try to focus the camera.
I've been watching it a bit closer now trying to see what the problem may be, and it really seems like a software problem to me, it will start the test, flip up the mirror, capture an image (for the live view), flip it back down, move the focus (I can tell via the distance scale) to infinity, and then do nothing for ~30 seconds before giving the "focus timeout" error.
I'm now in the process of trying to return the software for a refund, but I still can't even get a response from the company. Quite frustrating.
