One other thing - you're shooting with a 7D, right?  That means a very, very narrow AoV.  One challenge you'll face is simply locating the subject you've seen with your eyes once you start looking through the VF.  When you attach the hood, try putting the attachment screw straight up, then use it like a gun sight to pre-aim.

That's avery nice Trick....... thanks

And free, too!  A non-free (but not too expensive) more sophisticated alternative is a red-dot sight with a Weaver-mount hotshoe adapter. I have that setup, works nicely.

Yes for reach with the 1.6 sensor and also since 1div is discontinued Canon will not support that plat forum going forward.

They'll support it for a few years to come.

I have a 7D as a 'backup' but I've strongly considered swapping it for a refurb 1DIV.  The better AF and IQ more than make up for the difference in crop factor, plus the 1-series can AF at f/8.

No worries!  Thanks for posting your impressions.  Honestly, the most important question on most people's minds is when it will actually be available...I don't suppose the rep gave any indication?

Interesting. I suspect another way to tell would be to look at the lens mount contacts on the 200-400 - 10 contacts means TC-compatible (electronically), 7 contacts means not.

Thanks!

FWIW, it's not the heft - I have no problem swapping a 1.4x or 2x TC on the 600/4 IS II.  The question is whether or not there's room at the back of the lens for the protruding front of the 1.4x TC.

I wonder...since the 1D X can now AF at f/8, can you mount a 1.4x TC behind this lens for a 392-784mm f/8 lens??

1DIV, no question.

i bought my 70-200 II in 2004

Hey, can I borrow your time machine?   ;)  Since the 70-200 II wasn't released until 2010, I can't see how else you could have bought one in 2004...

...It is difficult for Canon to make a bold move with the 6D like it did with the 5DII, as it has to play nice with its more sophisticated bigger brother...

Probably true although the gap between them seems huge.  Canon certainly could have made the 6D much more attractive and appealing to a larger consumer group with adequate AF, 100% VF, CF card, and 7D/5D ergo.  IMO, Canon has deprived themselves from 6D sales due to the specs.  I for one was a potential consumer until the specs came out.

If you want/need great AF, 100% VF, CF card, and 7D/5D ergo, Canon wants you to buy a 5DIII.  They are good at up-marketing. 50D users were pushed to the 7D vs. the 60D in the same way.  I think the 6D is targeted at xxxD/60D owners, not 7D/5DII owners, in terms of an upgrade.

What concerns me is I am not getting a consistent sharpness 'reading'. Shouldn't I get the same resolution 'reading' even if the distance are varried?

No, you shouldn't.  If you change the framing, you're changing the size of the target image projected on the sensor. Further away (at same focal length) means smaller target covering fewer pixels on the sensor and thus a lower resolution.  When you use a real test chart (ISO 12233 type), you must frame the full target for the resolution values to be accurate (there are framing marks on the chart).

So, what's odd (besides the total of 27 being an odd number, not even, that is)?  The 1DsII is two bodies back now, the 85L MkI is quite old, the 70-200 II is current.

Actually, I was really hoping Canon would have put an EOS 1D X window decal in the box, like Apple does. *sigh*

I wouldn't expect an updated ST-E3 anytime soon. But I would expect an -RT version of a 4x0 flash pretty soon.

If you're getting inconsistent FoCal results, it's almost always due to insufficient light or an unstable support. EV should be 10 or higher.

Good move IF you don't also need to trigger a monolight (that's why I haven't done the same, I just hope PW hurries up with the next firmware update).  The only advantage to the PWs besides that is the ease of altering power output with the AC3 vs. the ST-E3.
