My 1.4X mk2 is about 8 years old and has served me well. I just recently purchased a 100-400 mk2 and think the old extender could be improved by the mk3. I have seen charts showing the lens plus extenders, anyone have a link? Any personal experience?

Found some charts in this review. Looks like the new extender is pretty good, not sure what the results are with the old one. I will keep looking.

I have that combo, and very happy with results - yes, I read somewhere that indeed the mk3 1.4tc is better and will give better results. As a matter of fact it was recommended to use the newer version with the 100-400mk2 probably a key-worded Google search will find the review again)
Did not use the mk2 on this lens, so can't tell much more

Thanks for the reply, but I found this old thread with a reply from Chuck Westfall indicating the upgrade was not needed for non primes.

I wish I had the gear to do the comparison for you
I recall the main reported difference was at the edges of the image - not so much in the centre - between the v2 and v3 extender. For landscape use, that may be just where you need it Ben

Better yet then - no need for you to upgrade.
I figured that might as well start with a newer version in my case (as did not have a previous version)

My interpretation of Chuck's reply to my email is that you won't see the AF improvements with the 100-400 II and 70-200 f2.8 II that you see with the big whites. The digital picture does a comparison here of the 70-200 II with both versions of the 1.4x and the edge to my eyes goes to the vIII. Unfortunately Bryan hasn't compared the two 1.4x using the new 100-400. Anecdotal evidence here on the forum is that the vIII has less CA. I think the resolution differences are probably slight, you know 5DS vs 5DSR. The newer teleconverter has easy clean coatings and better weather sealing.

I was in the same quandary as you but eventually went for the upgrade under the assumption that when you are pushing resolution like that every little bit helps.

Thanks and good to consider. I have to sell something first, probably the 17TSE now that I have the 11-24 I am not using it much these days.

On the 100-4oo II the 1.4 III offers better image quality than I'd have guessed it would. For my work the main detraction is that I'm stuck with center AF point at f8. Strangely, that is the one limitation that has me yearning (again) for the 200-440 with TC built in.

I upgraded mine too. I sold the M2 so I never did any direct comparisons. I just went by the reviews I'm very happy with them (1.4 III and 100 400 II) together.

I would upgrade. The Mark III extenders were designed for the newest lenses starting with the 70-200 f/2.8IS II and everything since including the 100-400II. The IQ and AF is phenomenal for an f/8 nominal combo. It impresses me every time I use it and I use it a lot despite owning a few exotics...

I have both II and III extenders and used both on the 100-400 II. I see no real difference in IQ. The III seems a tad sharper in the extreme corners, but it seems to be a little softer in the center than the II. The white on the III does match better with the new white of the 100-400 II though

Also no real AF improvement either. Still have to tape the pins and work with sluggish AF.

I had them both briefly, before I sold my Mark II. In that time I was able to establish that the Mark III was slightly better on the 100-400II, but only at 100 percent resolution, looking intently for the very slightest of differences.

I upgraded to the Mark III solely for future IQ with prime lenses I hope to acquire. I'd have sold the Mark III if I was going to permanently stay with just the 100-400II, as I'd have pocketed $500 more.

The difference was so slight that I was never sure it was my imagination. To tell the difference, I had to lock down the camera to a support beam on my house to get adequate steadiness, and to shoot a few hundred yards away to exaggerate the need for resolution. At that distance, even good environmental conditions come into play and make differences difficult to tell without looking at many shots. I wasted a couple hours on it.

The upshot is that they're largely the same for that lens. But the III is more future proofed for later lens acquisition.

I upgraded from the mark ii to mark iii when I got my 500f4 about 5 years ago. I can't say that I saw any difference between the two.

The Mark III extenders were designed for... ...everything since including the 100-400II

And what's your source for this dubious claim?

Canon CPN Europe....and it is fairly common knowledge...what is your issue with that. Do you think they designed the thing to work with the 1989 lenses?

"The Canon EF1.4x III and EF2x III extenders are for use by anyone who wants a bit more reach from their lenses. The most likely candidates to require them for regular use are wildlife and sports photographers. Compared to their Mark II predecessors they offer photographers improved performance with the latest generation of Canon L-series telephoto and super-telephoto lenses."

http://cpn.canon-europe.com/content/product/lenses/efmarkiiiextenders.do

Next time try asking in a more polite manner...coming on to a thread and calling someones' comment dubious with no reasoning of your own to claim the counter is highly inappropriate. Manners please...this isn't DPR...well at least not yet...and if you are going to take the time to comment at least add something to the thread.

Ben -

I was in the same boat several months ago after I bought the 100-400 v2. I have several 1.4x II TCs (one of them virtually lives on my 500 f4 v1). I rented a 1.4x III for a couple of days and ran some tests, and found no appreciable differences between the 1.4x II and 1.4x III with the new 100-400... Save your money!

Claims from Canon aside; I have trouble understanding how an extender can be designed to work better with the new lenses.
It would seem to be more of a situation where the new lenses are better and improving the extender just keeps the picture quality as high as possible in line with that.
I do use the V3 extender on my NEW 100-400 and it works well. Picture quality is degraded a bit ... just like on my old 500.

If you read the "Key benefits" section under the CPN link I posted above it goes into some more details. One difference in the Mark III's was the addition of a chip in the TC to do more communication with the new lenses they were making at the same time. The first 2 lenses were the 300 f/2.8 and the 400 f/2.8 IS II lenses and as I understand it that trend has continued in all the subsequent white primes and white zooms which would include the new 100-400II.

Another source is Bryan's review of the mark III extenders at TDP...here is a small part that addresss the new chips and the use on older lenses.

"Improvements in the Series III extenders promise to perform especially well on these specific lenses.

A microcomputer integrated into the Series III Extenders promises faster autofocusing and increased AF precision when used with the Canon IS Supertelephoto Series II lenses mentioned above and (I expect) all future compatible lenses. Better optical quality is also expected.

Note that "AF precision remains the same as the Series II Extenders when the Series III Extenders are used with earlier extender-compatible EF lenses." [Canon]"

That makes sense for the AF side of things. So it may AF better, but optically very close.
