E-mails have occasionally been troublesome with the SMF forum software.  New software is on the near  horizon which might fix this, and certainly has a lot of nice features.

See which lenses cause the issue. 
Activate the expansion points.  If it has difficulty finding focus, you will see the expansion points briefly flash as it calls on them for help.  Pg 72-73 of our manual. 
The camera will focus on the center point unless it can't find enough contrast, then the expansion points help out.
Some lenses are just plain erratic in focusing, even L lenses. 

Software & Accessories / Re: LR4 update later this week
« on: April 09, 2012, 09:16:24 PM »
Any firm date date on lr4 update?

The thread actually refers to the LR4 RC1 availability which fixes some of the issues with the original release plus supports 5D MK III.  Its been available for a few days now, and seems fine, at least for what I've done.
The official update release will likely be out in a week or two, depending on what else is found that needs a fix.  I have not seen a firm date.

Software & Accessories / Re: FoCal Pro Beta for 5D MK III AFMA
« on: April 09, 2012, 09:11:49 PM »
I spent a few hours today getting up to speed with it, it is a beta, so there are a few quirks.  I had difficulty with both my 100mm L and 85mm f/1.8 with consistent AF results, I had similar issues with those lenses on my 5D MK II and 7D.
I calibrated my 35mmL, 24-105mmL, 50mm f/1.4, 85mm 1.8, 100mmL so far.  Tests after the cal show razor sharp images.
I am planning to calibrate the long zooms tomorrow, since the setup is different for them.
They have added a lot of new features such as calculating the sharpest aperture of your lens, dust analysis, etc.  I did not get into those yet.
Because they have not yet received the SDK for the MK III, you must manually enter the AFMA settings into your camera before each series of exposures at that AFMA.  You get onscreen guidance, and a error message if you do it wrong.
For zooms, set your lens to wide or telephoto and it will recognize the setting and guide you to run the AFMA and set it into the body .  Then, zoom to the opposite extreme and run the AFMA again, setting the result into your body.  I did this again after setting both to see how much interaction there was.  I received the same result at wide the second time, so there is very little interaction at wide after setting the telephoto.  I did not have to set a large AFMA value, so it might be different if you set wide to -10 and tele to +17.  I'd then run the wide again with tele to +17 and see if it changed.
Even having to set AFMA manually, it still goes pretty quickly once you get the setuo and process down pat.

Software & Accessories / Re: SD/CF adapters
« on: April 09, 2012, 08:57:22 PM »
The 5D MK III does not have room for CF Type II cards, which is what most adapters require.  Its on pg 32 of the manual in the footnote. 
The 5D MK II did accept a CF Type II card because it had more space.
If you can find a SDHC or SDXC adapter that fits in a type I slot, then it might work.  I've only seen them for micro sd cards.

Canon General / Re: Should I move up to FF or get more lens
« on: April 09, 2012, 08:37:36 PM »
Probably a ton of other posts like these here already, but I thought I'd ask specifically for my situation.

I currently have the following gear
  • 550d
  • aluminum tripod
  • 10-22mm EF-S
  • 18-55mm EF-S
  • 18-200mm EF-S
  • 30mm 1.4L EF
  • 50mm 1.4 EF
I mainly enjoy shooting landscapes, buildings and night photography.  I've only been serious shooting for about 6 months.  I don't make money of my pictures as this is just a hobby.  And moving to FF, in particular the 5dmk3, interests me for low light performance as the biggest issue i have is with my night shots and AF in low light.

What I wanted to ask, would you recommend that i just get the 5dmk3, where I could only use the 35mm and 50mm.  I'd be pretty limited by my glass, and after dropping $3500, it'd be a while before i could get more glass.  Though eventually i'd like to get the 24-70mm mk2

Or would you recommend I spend more money on gear and glass to make the move to FF lens painful when  it happens?  That and i could work more on my shooting skills and get more experience.

If i picked up more gear, I'd be looking at
  • ND filter
  • 6xx Flash
  • lightroom
  • possibly a macro lens

Picking up the 5dmk3 would be a stretch financially, but doable, and the gear no sweat.

You might be better off getting the 5D MK II and the 24-105mm kit lens while selling your crop camera and lenses.  A 17- 40mm L would be plenty wide and can be bought used for about $600, the same as your 10-22 would sell for.
I sold my 5D MK II to finance my 5D MK III.  Its a nice camera, but so was the 5D MK II, I think you would be quite happy with it.

Thanks for posting ronmart, and ignore the trolls. 
I personally do not notice any big difference under normal lighting.  However, I have noticed better DR in difficult lighting, and, of course amazing ability to retain at least a usable amount of detail at ISO 25600.
I have posted numerous images with my 5D MK III that are in the forum.  I'll be doing some AFMA of all my many lenses today with the beta version of FoCal Pro which now supports the 5D MK III

Software & Accessories / FoCal Pro Beta for 5D MK III AFMA
« on: April 08, 2012, 10:19:50 PM »
Reikan foCal has released a beta for Pro users that supports AFMA of the 5D MK III with some limitations.  Its 5 or 6 weeks more before the SDK is released by Canon, so it is a clever work around.
I'll be trying it tomorrow on my 5D MK III.
For those who haven't heard of it, it will control your camera and do a semi automated autofocus micro adjustment.  I use it, it is accurate and useful. 
There are no free trials, you must buy it.  However, use this link for a discount  http://www.reikan.co.uk/focal/mbp45/

Software & Accessories / Re: Benro A-550 EX BH-1 tripod recomendation
« on: April 08, 2012, 09:41:21 PM »
I'm thinking to buy Benro A-550 EX BH-1 as my first tripod from this seller in China (not sure how trusty it is, so would be gkad to hear from somebody who had had business with them):http://www.ebay.com/itm/Benro-A-550-EX-BH-1-A550FBH1-Tripod-KIT-FAST-SHIP-/140727941239?pt=US_Tripods&hash=item20c409f877#ht_5499wt_1163

The cost is 155$ and free shipping. I'm an amateur photographer and will only use it occasionally so I can't afford anything more expensive (actually this one a bit to expensive for me). I've heard some good reports here and elsewhere on Benro in general (usually the more expensive). I was wandering if someone used this particular (or similar) model and can testify? It comes with a ballhead and seems very reasonable for it's price.

I'm using 60D with 55-250mm lens (my heaviest for now).

I would also be glad to have recommendations on other tripods in this price range if you believe they are better.


The tripod you point to is about 52 inches tall without extending the center column.  I have a set of Benro legs and they are fine, but much heavier than those.
I also bought two Benro BH-1 heads from China.  They were pure garbage, I only used them once.  They are not smooth, and worst of all, they slip if you do not use extreme force to lock them.  Don't go there!!
Get a tripod tall enough so that you do not have to extend the center column to stand at it and look thru your viewfinder.  Usually, thats about 58 inches or more.
You are not going to find a pro quality tripod in your price range, but at least get one the right height.

Its close between the 1D MK IV and the 5D MK III.  Finding a good low usage 1D MK IV seems difficult.  Prices have shot up to silly levels for new ones.
A good 1D MK IV is going to hold its value for many years.

Lenses / Re: Love to have an affordable and lightweight 28-300.
« on: April 08, 2012, 06:10:46 PM »
I picked up a used 28-300mm L IS yesterday from a local Craigslist seller.  It was dated in 2004, and purchased in 2006.  It looks and operates like new.
I spent all morning doing a AFMA with my 5D MK III.  This was just shooting the long railing on my deck, and checking longer distances.  It appears that there is quite a bit of interaction of the AFMA settings for wide and Tele, so I also checked 135mm to see if it was possible to manipulate the settings to get 135mm perfect as well as 28 and 300.
At full aperture, the lens is not the sharpest I own, and not as sharp as the 35-350 I had last year.  After adjusting AFMA, I tool some shots at f/8 and they were much sharper, of course.  I'll try f/5.6 and 6.3 next.
I have a 70-200mm f/2.8 and a 100-400mmL, but this lens just seems heavy! That could just be me.
I'll play with it for the next few weeks or months before I decide if I'll keep it or not, I like the idea of a super zoom, but I need to get consistently sharp images from it. 
The spot AF on my 5D MK III is a improement, like my 7D, I can pick out a target in a tangle of brush and focus on it.
Both were with my 5D MK III 300mm ISO 125 f/8 The bird is approximately a 100% crop


Lenses / Re: Serial number dates
« on: April 08, 2012, 05:50:46 PM »
There is no list of dates versus serial numbers that I've seen.  Many lenses had a date code on them, so finding that is your best bet.  However, lenses that have been service ofteh have the part with the date code on it replaced, so it might no longer be there.

EOS Bodies / Re: The Light Leak Issue
« on: April 08, 2012, 05:08:00 PM »
The metering sensor is under the mirror and is used to set aperture and shutter speed.  This means light is getting to the metering sensor.  Obviously, if it gets to the metering sensor, then it probably gets to the main sensor as well, its just not very much light.

The metering sensor was under the mirror in old designs, but these days it's actually up in the pentaprism housing (labeled in the upper right of this diagram taken from a Canon tech report):

So, light that reaches the metering sensor should be blocked from hitting the image sensor by the mirror when it's flipped up during the exposure.

OOPS, its the AF sensor down there.  I knew that, just getting too old. :)

EOS Bodies / Re: 5d3 - DPP to jpeg vs. DPP to tiff to pshop jpeg

Canon has indicated a fix for DPP is coming.  Until  then, another thread about the issues won't get attention.

EOS Bodies / Re: AIFocus works!
« on: April 08, 2012, 12:53:21 PM »
What AI focus does is try to determine if a subject is moving towards or away from you, or staying in the same plane.  Then, it selects either one shot or AI Servo.
Rather than have my camera guess (It will occasionally guess wrong), I set  AI Servo unless I am capturing a image of a stationary subject at a reasonable distance or on a tripod.  Even swaying 1/16 inch forward or backwards at macro distance is going to ruin a image.
Your camera detected this and used AI Servo.  AI Focus is like the green button for AF setting.
