Kenko has better IQ & compatibility than Canon 1.4 MK2.  There is no reason to buy Canon 1.4 MK2.  However, you really should consider Canon 1.4x MK3, which has better IQ and better compatibility.


 can you site a source.  I  was  less to believe that the mkii and mkiii are identical in image quality but where they differ is in build quality.


I don't know if new 5D3 firmware screws up Kenko 1.4x TC or not.  If that's true, Kenko may not be your choice.  By the way, Canon 1.4x MK2 and MK3 have different IQ.

I was planning on getting the Kenko 1.4 because I have a 70-300L and the Canon won't fit on it, but the Kenko will.

I have a 5DIII and 6D. Anyone's experiences with the Kenko?

I'm planning to get the Kenko Teleplus PRO 300 DGX 1.4x AF Teleconverter.

I heard/ read somewhere that the kenko  causes the 5d  mkiii to freeze and requires a power off and on.   I stopped considering kenko  atthatmoment..  but i don't remember where i read/ heard that.

Probably in this forum, posted by Mt. Spokane.

I posted this on page 2 of this thread. It has come up in several other threads. The Kenko can freeze the 5DIII so don't buy the Kenko TC.

I bought the Kenko and experienced lockup of my 5D MK III when used with a 100mmL.  It turned out that the issue was related to AFMA, and turning off AFMA caused the issue to go away.  Since I need a +10 ASFMA on my 100L, it also caused sharp focus to go away.
However, there are apparently only a very few lenses that have the issue, so a buyer needs to decide and research.  Some Day, Kenko will come out with yet another firmware version.  It won't work on all lenses / bodies either, and some will blame that on Canon for coming out with new lenses and bodies.

It might have been Mt. Spok... but it was probably a forum I started a while back.  I was asking if there was a substantial difference between the mkiii, mkii, and the kenko...

Long story short, I picked up a used mkii for $150.

I'm pretty sure that's the same model that I have, and it works fine with the 70-300L and my 6D.  No idea about the 5D III.

The Canon 1.4x TC will work and AF with the 5D3, but only the long end of the zoom will be available to you:

I have a chance to get a nice used Canon 1.4 II TC for the same price as the Kenko 1.4 pro 300 DGx. I'm not worried about weather sealing, as I don't really shoot much in the rain. It will be mainly to increase the range on my 70-200 F4 IS for getting a little closer to the birds that sit on the branches around my feeders that are about 25 ft from me. I can get some nice shots, but I'd like to fill the frame a little bit more. Other info.. I use a Canon 60D and I mount on a tripod with a wired trigger with mirror lock-up.

I know their will be a loss in image quality, but is one better than the other for the least amount of loss?

Thanks in Advance,
Matthew

Matthew, I'm stunned that you even need to ask. buy cheap buy twice...or just get the pukka version 1st time ;-D

I've had the canon 1.4 mkii for about a week now, and outside of some test photos... I haven't done jack squat with it.  I have a fear that I might just be a gear collector at best... and a mediocre photographer at worst. 

Though in my defense... I do have a 2 week old baby... so I have been preoccupied and mostly photographing the sleepless wonder.

Thanks for all the info. I thought I'd let everybody know that I had decided on the Canon Teleconverter. I did save a little extra money and Purchased a new MK3 version. Since I had to save a little extra money to be able to purchase this, I just got it a couple weeks ago.

Been using it as much as possible and I think it does a great job! I do want to get a longer lens, but that will have to wait a lot longer.

Thanks for all the information and posts.

 can you site a source.  I  was  lead to believe that the mkii and mkiii are identical in image quality but where they differ is in build quality.

I used a Canon mkII 1.4x TC for quite a few years and them bought a mkIII before I sold the mkII.
So for a few months and was able to compare them side by side.
The mkIII has a slightly longer reach, I think the mkII was slightly under 1.4x and the mkIII is slightly over. The mkIII renders slightly brighter exposures for the same settings....which leads me to belive it's a bit brighter. The AF speed and tracking is slighly slower but more accurate with the mkIII over the mkII. The mkIII is slightly sharper and has slightly more constrast / colours. The mkIII frame corners are better, less vignetting and sharper. It's not a night and day experiance, but the mkIII is noticably better image quality wise.
