I suspect these batteries would benefit from calibration.  Apple has recommended periodic calibration of the LiPo batteries in their laptops (charge to full, drain to empty, recharge to full).  The LC-E4N charger can run a calibration cycle, and the 1D X tells you when one is needed.

Even with the 5Diii and 1DX you still select "Fully Automatic" but instead of it doing it all itself it prompts you when you have to change the AFMA values manually.

Ahhh, thanks.  I've actually never done an automatic AFMA - when I got my 1D X, that wasn't supported so I needed to take the shots myself and use manual mode for analysis.  I've just kept doing it that way...

notice that you use a 1" clamp.  Any reason for the 1" versus 2" clamp?  I would think with your big glass, you would want a larger clamp for greater security.

A wider clamp provides extra stability when the clamp is 'upright', but there's no clamping strength benefit in the 'upside-down' position.  Since it holds as strongly, and a smaller clamp is easier when holding the camera in portrait orientation, I picked the 1" version over the 1.5" RRS clamp or the wider Kirk models.

I agree with kennephoto, you will miss IS at the long end!
Yeah I hadn't really thought about that.  I was more thinking range and image quality.  From The digital picture it looks like the 70-200 f/4 (non-IS) has better IQ than any of the other 70-200 versions except the 2.8 II.

I'd look again.  The ranking is f/2.8 IS II > f/4 IS > f/2.8 non-IS > f/4 non-IS = f/2.8 IS.

It's also nice having all your flashes at the same max power.  I've got an ST-E3-RT and three 600's, and it's a great setup.

If no one minds one more potentiall stupid question (which I'll research some articles on anyway):
Can a polarizing filter be helpful at times for wildlife (on water, bright sun, etc.)?  I've gotten great results with mine for landscapes, but "yes" for wildlife in certain conditions or not really?

Yes, as long as the loss of ~1.75 stops of light doesn't drop your shutter speed too low.

I use Flickr, debating between extending my Pro membership there or moving to 500px.

hooked up 5D MK III + EF 50mm f/1.4
First Time:
Tried the "Fully Automatic" mode ...

Full auto isn't supported for the 5DIII - you need to be in MSC mode.

Just means it's getting up there in cycle count.  It still has quite a bit of life left, so keep shooting!

Might the answer be to rent a 100-400 and call it a day and then, if I love it, buy the 100-400II one day?

Might be...if you're willing to carry the weight.  If you'll need 400mm much of the time, that's the way to go, else the 70-300L is the better lens.

Can we assume that the 70-300L met your expectations after putting it through its paces?   ::)

Not yet - that statement is primarily based on specs and test charts.  I got my 70-300L just yesterday, so except for a couple of initial test shots, all I've shot so far is the FoCal test image (result is +2 AFMA across the range).

But...I'm goring out on an excursion this afternoon, and bringing the new lens.

The 100-400 weights 3lbs or so, bring a tripod  ;)

I've taken literally thousands of shots with the 100-400L, and even more with the 70-200/2.8L IS II (which is slightly heavier).  Of all of those, perhaps a few dozen were taken from a tripod.

The TS-E 24L II is pure awesomeness...   :)

It does work best on a tripod using Live View - both for focusing and for metering (tilt/shift movements affect metering, so if you're not using Live View, you've got to meter before the movements, then dial in that exposure in M mode before taking the shot).

I occasionally handhold the lens with shift movement, works ok in good light.

The 5DIII has an Xsync of 1/200 s, so unless you use high speed sync you cannot set the shutter faster than 1/200 s. When you attach a flash, Auto ISO is fixed at ISO 400 (count your blessings - older bodies fixed Auto ISO at 400 if you put the camera in M mode!), if you want different you have to manually set the ISO.  Note that in Av mode, the camera's meter is setting background exposure, and the subject exposure is set based on the E-TTL II pre-flash.

I highly recommend you read Syl Arena's Speedliter's Handbook.

Most importantly Haida is slim. So if I do stack with a graduate ND, the vignetting should be minimal.

If you do want to stack with a graduatd ND, you should be looking at the Lee system.  The problem with screw-in grad NDs is that the dividing line is right in the middle, where you usually do not want it, and it cannot be moved.  A 4x6" filter in a square holder gives flexibility to match the gradation to the scene.
