Four images of Navy's Blue Angels taken with Canon 5D Mark III and 24-105 f/4L.  Each image shot at 105 mm with the same exposure settings:  ISO 800, f/8, 1/3200 sec.  Really enjoyed the Airshow and satisfied with results even though limited by 105 mm max focal length.    :)

My understanding is that STM lenses offer quieter focusing for video and the new T4i is apparently compatible with STM lenses for this purpose.  Is this also true for the 5D3?  The 5D3 user's manual makes no mention of STM.  If 5D3 not compatible, can firmware update make it compatible?

Can you post a snap of the bottom of the camera showing the scuff? One thing you might consider is attaching the BR to a Wimberly P5 generic Arca Swiss plate, that may keep the connectors farther from the camera body.

I also use the RS-7 with the 5D3 with an RRS L-plate attached.   I connect to the L-plate with a Kirk 1" clamp that is connected to the RS-7 threads.   This fully protects from metal-to-metal.  Also, it's very easy to get on and off a tripod - quickly.

I just bought the RS-7 for my new 5D3 and like it a lot.   The RS-7 threaded attachment has a rubber washer that protects the camera from metal-to-metal contact.  So far I haven't had and problems.

Secondly, leaking LCD is very disappointing. That just reflects the deterioration of Canon's workmanship or quality control. For those who understand how Canon's cameras were put together, can you please shed some light on what type of "countermeasures" would be deployed to fix the issue? I think it would require significant work to get to the part between the LCD and the sensor. I am just not 100% confident about the skills of the technicians at the Canon service center. I suggest that if the issue does not bother you, just go out and take more photos. If it does, return it now and wait for a few months to get a new one.

5DIII, x0D, 1v, 16-35 L, 28-70 L, 70-200 2.8L IS, 50 1.4, 100 2.8L IS.

Seems to me that Canon may have felt pressure to get the 5D3 to market, in presence of earthquake issues and competition from Nikon.   There is no other excuse for not discovering this problem in QC and fixing it before distribution.   Not good.   But I am confident Canon can and will fix it.

This kind of pisses me off. Not because I feel like I got a defective camera or that I even think this issue would really affect me. I'm pissed off because I will now have to decide if I want to be without my camera while it is getting an updated LCD cover or if I want to ignore the recall and deal with whatever the consequences of that are...

Choices, oh choices....  at least you have this choice

EOS Bodies - For Stills / Re: Eye-Fi usage on 5D3, with C1, C2, C3?

If you're wanting to run the SD card as a parallel back-up, I guess this doesn't help, but why not shoot just RAW to the CF card and just JPEG to the EyeFi card? 

I was actually playing with the C1, C2, C3 settings last night and I thought that you could tie the recording scheme to them, but they are separated out and I can see pluses and minuses both for that decision.

Can you share your pluses and minuses?  Thanks!

Canon 5D III with 100 f/2.8L macro on tripod, shot in RAW converted to JPG in PS5

rose#1 --- at f/8, 1/50s, ISO 100.

orchid#3 --- at f/16, 1/10s, ISO 100.

Thanks, I'll read them.

+1  I'm reading the manual, but finding it a bit vague.  Hope to learn from these links.  Thanks for posting.

I use DoF preview all the time with macro work...

Pre-ordered my 5D3 w/24-105 kit on 3/2 at 9:30 AM PST.   Received 4/2.  Diving into the manual....

t.linn  NICE REPORT!...   I have a question???? When using  AEB...can you have exposures that are longer than 30sec. ...or do you have to put the camera on Bulb for any shutter speeds longer than 30 sec?, (like the 5D Mark II).
I do a LOT of HDR shooting and I have a Promote Unit (which is like hauling around a colostomy bag with my camera with 2 tubes, manual set-up. etc.. ....NOT a fluid way to work to say the least....but the only way I can shoot over 3 AEB shots without touching the camera... even with the Promote Unit I HAVE to touch the camera to get any exposures over 30secs.).  The expanded AEB feature alone on the MkIII may get me to sell my II and purchase the upgrade...but being able to go longer than 30sec. in a bracket will be icing on the cake.
I don't understand why this is such a "slow-to-come-about" feature.  There is a computer under the hood here...it should be pretty straight-forward to satisfy what I would call a basic photographic need. Timed long shutter releases.  Right?

Canon DSLR cameras are limited to a maximum shutter speed of 30 sec, period.  All shooting conditions, including AEB or HDR options have to live within that constraint.  To automatically achieve exposures longer than 30 sec requires a fundamental camera design change - extending the 30 sec maximum to something larger.  But what would you pick?   Right now it's controlled by BULB!

EOS Bodies - For Stills / Re: 5D Mark III AEB/HDR Question????
« on: April 04, 2012, 12:51:20 PM »
Well, the in-camera HDR is really a gimmick for casual users. It's JPEG only, and the HDR options are limited. For the in-camera HDR, it can only burst 3 exposures +/- 3EV. For normal AEB, it allows up to 7 exposures, also +/- 3EV.

So the HDR function is just a subset of AEB, since it still saves the 3 raw files (if you keep the default options). You could just as easily do a 3 exposure AEB instead of using HDR.

Since you shoot HDR so much, you really shouldn't consider the built-in HDR on the 5D3. I'm sure that you'd be disappointed by it. It's interesting, but not a serious attempt at good, professional HDR. As you suspected, the AEB is really what you need, but since it's limited to +/- 3EV, you'll probably still end up doing manual bracketing, so that you can go well beyond 3EV.

I'm not sure why they limit it, since theoretically the camera should be able to automatically go up and down with the exposure as much as you want.


I shoot HDR using the Promote Control unit you mention, and I find it very effective.  I find HDR is best done shooting manually via the camera mini-USB port, varying only shutter speed and taking all the images without touching the camera.  As you mention it is possible to bracket a very large range of exposures - but not exceeding 30 sec.

The AEB on the 5D3 allows up to 7 images, and this usually covers needed range for most HDR situations.  I process these in post using Photomatix.

I too wish that the HDR option built into the 5D3 had more options, mostly more than a 3-image bracket range.

I have the RS-4, which does have a pocket, but it's a small one (two CF cards at most).  The RS-5 seems too bulky to me, as well.  The RS-7 looks ok, as does the RS-Sport-2.

I decided on the RS-7 with the curved strap and the Kirk QRC-1 clamp.   This is an excellent way to go to/from the tripod - with one strap and multiple camera bodies.   Thanks for your very helpful input!

Couldn't find the Kirk 1" clamp on the Kirk website.  Can you provide link and clamp model number.  I'd like to consider this for comparison with another option I'm looking at - described below.
It's the Kirk QRC-1, and here are Kirk and B&H links.

Is the Kirk 1" clamp about the same size as the B2-FAB?  I want to minimize size and weight of the solution.
The Kirk clamp (on the left in the images below) is smaller than the RRS B2-FAB (on the right), and doesn't have the little nubs on the bottom which you can see in the lower image. 

RRS suggested I either file off the nubs to connect the FastenR-3 (which it looks like was done for the photo on the RRS page), or just mash the rubber washer down on them.  Instead, I returned the RRS clamp, and kept the Kirk.

Most excellent!   The Kirk QRC-1 seems like the better choice (and costs less too). 

I've looked at the Black Rapid straps - the RS-4, RS-5 and RS-7.  Which one do you have - recommend.  I'm not too keen on the straps that have pockets for CF cards and cell phones - again, too much bulk.
