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).

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.

What body are you presently using?

 

If you want to use the 100-400mm II with the teleconverter, then you will need the 1.4x III.  You will need it to get active AF points at 400mm, when combined with the 7D2..  I would have to look it up, but I doubt the older TC would allow for any f/8 AF points.

 

The 7D2 will only give you one f/8 AF with the combo.  As good as the 7D2 is, I do not think it is as a good of a choice as it once was.  Both the 80D and the 6D2 will give you 27 AF points with that same lens and TC combination.  

 

The 80D and 6D2 bodies also have AF systems that are the equal of 7D2, if not better because of the more sensitive AF points.  The only real AF advantage the 7D2 has are the AF Case presets, which can be emulated with a custom shooting mode: C!, C2..   And, the 7D2 is due for an upgrade at any time now.

I am not suggesting that you not buy the 7D2.  Just realize that less costly bodies can equal its’ AF performance, and have lower noise and better IQ, IMHO.  The 7D2 still has the better build, dual CPUs and card slots.  But, that’s it.  

 

But, if you’re shooting with a 600mm f/4, then you may want to have one just the same, and have already weighed all of these factors.

Thanks for the detailed reply.   I *was* wondering if the 80D might be a good choice, as I am

not a professional photographer and would just as soon keep all of my money in my lenses.

I will review the 80D specs before I make any decision.

What’ types of things do you normally shoot?

 

The 7D II is somewhat optimized toward action photography.  If this isn’t what you primarily shoot, you might just be as happy with an 80D.

I agree with Tim.  And, I ask again, what body are you currently using.

 

If you need a replacement for a nonfunctional body, then the 7D2 might be a good replacement.  But, if you already have a functioning body, then the 7D2 may not be the valuable upgrade that it used to be.  

The current Canon lineup for high performance APS-C sensor bodies is sort of stuck between golf clubs, at present.  The best choice, the 7D2, is becoming outdated technology.  Less costly bodies are have better IQ and AF sensors.

 

If, and when, Canon announces a DSLR to supersede the 7D2, if the lessons of the past are any indicator of the future, then any 7D3 will be a high performance, state of the art camera body for action photography.

Sorry, I thought I had said... I have a 30D.   And I shoot almost solely birds.

The 7D2 is, for all practical purposes, the APS-C equivalent of the 5D Mark III. The features and controls are virtually identical. (My wife once picked up my 5D3 and used it for an hour, thinking it was her 7D2.) So I'd expect the 7D3, if one materializes, to be the APS-C equivalent of the 5D Mark IV.

"...then the 7D2 may not be the valuable upgrade that it used to be."

 

It is if build and a robust body is at the top or near the top of your list of requirements.  The mostly plastic xxD and Rebel cameras are not even close to the 7 series in build.  And, no matter what camera comes out to replace the 7D2, the 7D2 will remain as one very capable camera.  It isn't as if as soon as a new body comes out the old one stops working.  It doesn't.

A quick followup.   If I sold *both* my 1st gen 1.4 and 2.0 TC, is there any issue with using the 1.4 gen 3 with my new 7D2 and the old 600 f4?

 

Although the old TCs may not be worth much, anything to help offset the cost of the new gear would help...

The most recent releases are supposed to always be backwards compatible.
