EOS Bodies / Re: 5D MK 3 and auto ISO
« on: April 30, 2012, 01:08:53 PM »
What metering mode?  What subject?  What focus point?  Sample photos?  These are all necessary bits of information before anyone can possibly diagnose your problem. 

My wild-ass guess is that you're focusing and metering (in evaluative mode that emphasizes the focus point) on something bright (a natural thing to do in low light) thereby forcing an underexposure.

EOS Bodies / Re: Eye Fi and 5D Mk iii
« on: April 30, 2012, 04:32:12 AM »
I'm on my second Eye-Fi now (the first one corrupted images) and I've still got some kind of incompatibility or bug with it and the 5D3 where it will not turn on the WiFi if the card is set to selective transfer (using the "Protect" feature).  More info here... http://photography-on-the.net/forum/showthread.php?t=1179441

BTW, I see the Error 80 roughly 1 in 500 shots taken and I write RAW to CF and S1 JPEG to the Eye-Fi.

EOS Bodies / Install DPP without a CD ROM?
« on: April 25, 2012, 01:40:13 AM »
Both of my computers no longer have a CD ROM (this is 2012 after all)... how am I supposed to install DPP when Canon only offers downloads of updaters that require software already be present?  WTF?!  Are they afraid someone who doesn't own a Canon camera might want to run their RAW files through DPP for fun?!

I tried these instructions, but Canon have obviously changed something in the installer for the Mac...

Any ideas?

I recommend this guide in addition to the manual...

It's perplexing that the two organizations could produce such different results.

If you're switching to a Mac... definitely check out Apple's Aperture.  It has a very elegant intuitive interface and plenty of adjustment capabilities, although not as full-featured as Adobe Lightroom.

Some of my own thoughts...

#1... Good idea... What happens when the counter gets to zero and there is still room left on the card?  Does it say card full or can you continue shooting until the card is actually full?  And just a note... The counter will report the lesser of the shots remaining on the CF or SD card... So beware of this if shooting different image types/sizes to the two different cards. It's not clear which card is the limiting one, so another suggestion is to put an indicator or offer a firmware option to select which card to monitor. 

#2. This option is  designed for shooting in AV mode in low light  - and is a welcome addition - just the way it is (but having more shutter speed choices wouldn't hurt). If you need strict enforcement of shutter speed you should be using Tv or Manual.  Also, attempting to set a shutter speed of approx. 1/focal is the default camera exposure programming in Av... We don't need a firmware option for it.

#3. Strange. I don't use wrap around, but I could see how this is annoying if you do.

#4. I don't find this to be an issue, but why not?  I only use the 41 cross points which helps reduce the number of joystick operations required to move the AF point from one side to the other.

#1 - I have the camera set on "Auto Switch Card' and the screen shows the shoots left on the current card. I don't have time to look at the counter when the things go wild but I think / it seems that there is no negative number - the counter "improves" itself when it gets close to the limit. Most probably the algorithm is CounterNo = FreeSpace / FixedFileSize. The problem is that the FixedFileSize constant is a.) way off and b.) is not a constant, it is a variable (the cr2 & jpegs have compression). That's why a much better estimation is something based on global average (ie. TotalSizeShoot/TotalFilesShoot - and this number to be kept for each resolution / ISO) or much better on a moving average (the above number calculated only on the last 50-100 files).

#2
- Hello brother!  ;D A typical programmer response. ("This is not a bug, it is a feature") Sorry, but I don't think that 'broken by design' is a solution. :) See, we don't want to enforce a certain FIXED shutter speed. If I have a zoom, let's say 70-200 F/2.8, I simply cannot use Tv to set the shutter speed to... what? 1/200?? It is way to high in ever-changing light conditions. Remember we're talking here about an event handheld camera not a studio one. Yes, I know, IS. But I cannot think to Image Stabilization as a kludge for firmware shortcomings.

Another usage case: I have an UWA on the camera - let's say Tokina 16-28 F/2.8. Where to set the FIXED shutter speed? Based on common knowledge (and my tests confirm that) the lens deliver ultra sharp images even at Tv 1/16 handheld. But I cannot set it there because my subjects (men) are moving and hence, if the light permits, I want to have the shutter speed raised automatically and when they'll go again in the dark to lower the speed.

I use the Av mode but there is the same problem: the "approx" gives the blur of the image. We don't want the "approx" because this can be sometimes very "approximative". We need (imho) 'equal-or-greater'. And mind you, I found this issue by looking at blurred photos, not by nitpicking EXIFs.

Also, even if Av it would work I think that P mode is superior because it tries to get out the camera/exposure from the "dangerous zones" (slow shutter speeds AND open apertures) leaving you to concentrate on what to shoot / composition etc.

Because of all the above reasons, I humbly think that we need a firmware fix for it. Especially because it seems that it is a simple fix (they should change the test from something like "nearest value" to "equal and bigger ( >= )" if an option is set).

#4
- Thanks to validating me, but in fact it seems that you responded here at #5 :D . The #4 is a very powerful feature which would provide multistage fallback exposure programs. Let me give you an example based on what I said above:

Reiterating the UWA case: In studio, the above lens (Tokina 16-28 F/2.8 ) deliver sharp images at 1/F and it has the best quality aperture @3.5-8. However in the battlefield, having a 1/16 speed usually produces blurry hands, legs etc. but even so you can catch a very expressive shot.

So, roughly speaking, I would have like this:

  • Camera main settings: Av mode with F/4 - Auto ISO 100 - 6400, Min Shutter Speed: 1/60 (this is the best-case scenario which will cover 75% from cases)
  • C1: P mode - Auto ISO 100 - 12800, Min Shutter Speed: 1/60 (here I still try to freeze the men)
  • C2: P mode - Auto ISO 100 - 12800, Min Shutter Speed: Auto (the worst-case scenario: catch what you can)

...and in Super Safety Shift I would have set "C1,C2" - so if the camera cannot obtain the correct exposure with the main settings then it will try the C1 and after that the C2.

I hope that is clearer now,

J. Th.

A few more thoughts...

I think you can do what you want and probably get great pictures if you take advantage of the features you've got. Between the safety shift feature thats there, the control over ISO and min shutter you have, and the programmable custom modes, there's not a situation you can't cover.  Don't be afraid to turn the mode dial once in a while :)

Speaking of mode dial... I'm surprised you shoot in P mode most of the time. Why?  While I'm in no position to judge, I would encourage you to take more control over your photography...  For example, I dont know a serious photographer that doesnt care about depth of field, and shooting almost exclusively in P mode says you dont care.  It's very unusual.   I can't imagine shooting anything but a test shot in P mode myself.  While the 5D is a capable point and shoot, you're not getting the most out of it in P mode and as you probably know, wishing for more/different automation is not necessarily the best path to better photos.

I don't know how the camera meters in Live View...  Let us know what you hear on DPReview.

Does this happen when using the normal viewfinder method?

EOS Bodies / Re: Mark III metering
« on: April 17, 2012, 11:13:36 PM »
Evaluative metering has frustrated me at time as well, but you need to realize that it gives emphasis to the focus point... and if you're like me, you tend to choose a focus point with high contrast in a scene, and something well lit... that tends to be one of the brightest elements in the scene, and as a result, all my shots done this way come out underexposed.

There's a couple of solutions to this...
1. Business as usual but adjust exposure in post
2. Business as usual but use exposure compensation at the time of shooting
3. Focus and meter on something that's more neutral (mid-tone) and likely get a more pleasing and proper exposure but risk missed focus because your point is not high contrast (maybe less of an issue with the 5D3 and therefore a hard habit to unlearn for those of us coming from lesser focus systems)
4. Meter and focus separately (although this will require experimentation as well to determine what kind of point to meter off to get the right exposure, so I'm not sure it's going to be any better in the end and at least initially probably lead to a lot of poor shots)

Spot metering is not the answer for most of us... it's really for subjects who are not going to get exposed correctly because of strong lighting elsewhere in the scene and where you're willing to sacrifice shadows or highlights in the scene to make sure your very specific target is exposed properly.  In most cases, the situations that require spot metering are not going to yield a nice picture, so it's best to think about what you're doing and adjust your angle/composure.

EOS Bodies / Re: Canon EOS 5D Mark III Product Advisory
« on: April 15, 2012, 03:12:56 PM »

Has anyone really detected any exposure difference when shooting under the direct sunlight? If so, can you please share a few photos of the exposure display? I did the tests and didn't see any real issue. I look forward to esi32's testing results next week.

I'm not sure what the cause of my problem is, but these were all shot in direct sunlight using evaluative metering, with a single AF point on the subject (bird, person, etc.)... the whole lot is about 1 stop under exposed.  Note the histograms... nothing on the right third whatsoever.

5d mark iii light leak

light leak with normal operation in sunlight

That would explain my consistent under exposures in direct sunlight!

EOS Bodies / Re: *UPDATE* Canon EOS 5D Mark III Stock Delayed? [CR1]
« on: April 12, 2012, 09:44:45 PM »
It seems there are at least 4 problems this delay could be addressing that I've either seen first-hand or read about...
- Light leak
- 200/2 noise
- Error 80
- Underexposure (maybe related to Light leak)
Edit: Add front focusing with outer AF points wide angle lenses to this list of potential issues worthy of a fix

EOS Bodies / Re: 5D III error 80 and failure to release shutter
« on: April 09, 2012, 05:59:12 PM »
In my case, I was using it last week on vacation in the Caribbean and also used the dual card slots with RAW going to my old CF cards and JPEGS going to a new 16GB Eye-Fi... So perhaps there is something to the types of cards and or the Eye-Fi that relate to this. Unfortunately, I won't have an opportunity to shoot a ton of pics to test this theory until the weekend.

However, if I'm not mistaken, when this error occurred on my camera it was before I could take a picture, not after.  When it occurred, it was when pressing the shutter half way to take a shot, which made me wonder if it wasn't AF/lens related.  But I witnessed it on both my new 24-105 kit lens and trusty old 35L.

It needs more research and feedback to Canon. Hopefully it's a firmware fix and not faulty hardware.
