mixing and matching

[mitchmcc]

I have what I suppose to be a first gen 1.4x TC that I use with my 600mm f4 lens.

I am thinking of buying the 7D2 and the current 100-400 is II as well.    Would the old TC work with that,

or would the new electronics require the newest gen 1.4?

It is hard to have to replace everything!  (I am sure many of you have gone through this).

"...is there any issue with using the 1.4 gen 3 ..."

I don't have one but I would say no problems at all.

"Would the old TC work with that, ..."

The truth is it will work.  Almost anything can be made to 'work'.  The real question is, are you happy with the results? Everything that is newer or more current is going to work better and have better specs otherwise, why?

So, the question remains, are you good with how they preform.  IMHO, I would always choose the 7D Mk II over the 80D and I am a big fan of the 80D.  It is a camera I could love but not when you make it a 80D vs the 7D2.

Is it reasonable to use the 1.4TC with the 100-400?   Or better, does anyone do this?

That gives an f8 at at least 560mm, not counting if you still get the 1.6 factor due to the body.

That is pretty slow for a lot of bird photography, but since I might end up taking this outfit places I cannot

carry my 600, it might be a good option.   Do you agree?

     7D2 + 1.4 (iii) + 100-400 II   (or substitute the 80D for the 7D2)

I greatly appreciate everyone's help, as I want to put in my order pretty soon.

I have already put in my two cents.  Make your own choice, based on your own priorities and needs, not the preferences of someone else.

With the 7D2 + 1.4XIII + 100-400mm II = One AF point, the center AF point.

With the 80D + 1.4XIII + 100-400mm II = 27 AF points, three rows of 9 AF points.

The choice is a tough one.  Each body had distinct advantages over the other.  Hands down, the 7D2 has a better build and body.  It has a slightly higher frame rate, which is meaningless with a slow lens, or a slower AF system at f/8.

On the other hand, the 80D has higher resolution, lower ISO noise, and better AF tracking [higher keeps rate, IMHO] due to a better AF sensor.

I shoot my Sigma 150-600mm f/5-6.3 DG OS HSM Sports Lens at f8 all the time.

EOS 1DX @ 600mm, f8, 1/1250 SS. 1600 ISO

I hand hold almost all my bird shots but 560mm on a 7D Mk II with its crop advantage is goin gto be a real challenge to hold still at nearly 900mm. Of course I would give it a go!

I am used to using a tripod 100% of the time, so I would probably try that using the 1.4....

Unless you’re set up and not plan to move, then a monopod with a good tilt head works better for action photography when you’re on the move.  Most professional sports photographers seem to use them.

BUT, a monopod/tripod can slow you down when you need a quick shot, or if you need to angle the camera upwards.  Frequently, I will retract the monopod leg, and go “handheld”.  

It is a trade-off.  I have captured my best shots by parking myself somewhere and waiting for the wildlife to come out of hiding.

"parking and waiting" is how I get my best shots at Ft DeSoto Park near where I live...

JMHO, back off on the slidders in your post editor.

I do not know what you mean "adjust sliders in post editor"...
