Definitely yes. You get the latest and greatest firmware for the lens and MFA at 4 focal lengths at least. Plus the cost is minimal compared to the lens.

One thing that i am finding is that the 7D2 is unable to get a lock on smaller subjects, even in spot AF. I compared the 7D2 to the 5D3 AF on the same subjects and even with bright sunlight the 5D3 focus just locks on and stays put. I'm not sure if this is because the AF sensor design is different that the 5D3 or if there is some other problem with the phase detect software.
It's still MUCH improved over the old 7D but I think there is some room for improvement. Hopefully it's just a firmware tweak.
When shooting larger subjects like people, eagles and herons which are fairly large in the frame, the AF has no issues.
Anyone else notice this? Those with 5D3's are better suited to compare.
I have not tried the MK II, but one of the strengths of my original two 7D's was the ability of spot AF to lock on to a subject, even with branches or a chain link fence in the way. I'd be surprised if the new one is worse in that regard.
Yes the noise is quite better than the 7D and what noise creeps in at higher ISO's seems to be more random and smaller. It's still not as good as the full frame 5d3 or 1dx but for a camera that is less than 2K there is no match when you compare it to other brands as a system and not just on noise.
It's noticeably sharper than without correction.I did my 7D2/4005.6 at about 60ft. [..] My value of +4 seems to hold true throughout my working range.
And sorry again, but I'm confused: From what I read about these afma values, a value of 4 for a f5.6 lens shouldn't be able to make such a significant difference. Or am I mistaken?
Just read this review on http://www.amateurphotographer.co.uk/reviews/dslrs/canon-eos-7d-mark-ii-review , and to my surprise, the measured dynamic range value of 7D Mk2 at 100 ISO is...12.7!!! Opening up other reviews on the site, looking only at DR values, i found out that, at 100 ISO:
Nikon D750 = 12.71
Sony A77 MK2 = 11.94
Nikon D810 = 12.79
Nikon D4S = 12.66
Nikon DF = 12.66 (at 200 ISO) and finally
Nikon d3300 = 12.98.
Taking into consideration that, the specific review is not all bells and whistles about the 7D Mk2 but seems to point out the "goods" and the "bads" of the camera in quite a seemingly unbiased way, i feel no hesitation to say that the so called "guru-of-metrics" DXOMark is, some kind of, officially humiliated! Myself, shooting (as an owner) with the 7D Mk2 at present time and having tested (thoroughly) the D810, A77 Mk2 and D3300, i was sure that 7D Mk2 was very underrated by DXOMark and some other (strikingly) biased towards SO-NIKON sites, in terms of IQ and dynamic range; let alone the incredible high ISO performance and the AF system.
That's, for now, what i'd like to share with you; my thought, my opinion. Be lucky, be healthy, keep on living strong the joy of life.
If you had read the sentence following the sentence that got you all excited, you would have realized that in real world photos, the 7D2's DR is not anywhere near Nikon/Sony crop, let alone FF:
"Base ISO DR is a pretty impressive 12.7EV, according to our Applied Imaging tests. But in real-world use the sensor doesn’t perform quite as well as these numbers suggest, giving more noise in the shadows at low ISOs than its rivals."
DXO; 7D2 11.8 Evs, D7100 13.7 Evs, D750 14.5 Evs. These DR value's are what the author of that article is referring to in the second sentence.
Nothing to get excited about here, just move on.
The MkI and MkII versions of them can be stacked, the MkIII versions cannot.And, you can stack a 1.4X III with a 2X I or II.
Thanks! I was pretty sure that was the case, but not positive so I left it off.
I kept that combination just because I could stack them. I was going to stack a Kenko 1.4 with my Canon 1.4 when I ran into the issue of the Kenko locking up my 5D MK III (Some have now had it lock up their 7D MK II's as well.
