short answer is yes! I have owned the v II and sold them and got vIII and there is a marked improvement. Recently I posted photo shot with Canon 1DX and 1.4 and 2.0 vIII Canon teleconverters with Canon 600mm F4 lens and there is no appreciable degradation of sharpness with the vIII teleconverters. I will not post the photos again, but if you want to see them send a PM.

So spend the money for the latest technology - it is worth it.
BTW the vII 600mm f4 is also a significant improvement compared to the 600mm f4 vI; I have owned both.

Great question which I have no answer for ... But I will tell (and show) you the 1.4X II works great. I'm using it on a 7DII with a 100-400mm II. Yesterday I also used the 200-400 with a built in 1.4X and found virtually no better images over the 100-400 combination. The main difference is the 200-400 will strengthen your arm muscles and lighten you wallet ... faster. Have fun no matter which way you go. Best, J. Goffe

Thanks. Looks like I will bite the bullet and get the newer version since I cannot predict what I will buy in the future.

Thanks. I have the 70-200 4L, which is on the compatibility list.

Keep in mind you will lose one f stop with the 1.4 and 2 stops with the 2X

Taking this one step further (or backwards), isn't the original Canon 1.4X TC (I) the same as the II version, but just not weatherproofed? If so, and if the weatherproofing was no big deal, that TC could save you even more money.

That's true, but the III is even better. However, money often is the first priority - understandable.

If you are using a 70-200 f4 - IMO, there is NO advantage of the III version. One advantage of the II's over the III's is you can physically stack them - if that is important for you.

In a German test, the 4 element standard Kenko performed better than the Canon III version on the 70 200 f4 !

I used a Tamron SP 1.4X on the 70-200 f4 and was always totally amazed by the performance !
