Which is really better? Kenko 1.4 or Canon 1.4 Mark II?
« on: September 04, 2013, 09:31:19 PM »
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

OMG get the Canon. Not to knock the Kenko, I am sure it is not terrible, but small imperfections are magnified with teleconverters in a big way. This is not the place to cheap out! The Canon version III would be even better, but I say go for the Canon (and this from a raging Sigma fanboy!)

Nope, the existing comparisons show that the Kenko is sharper in the center but worse on the edges vs. the Canon mk2, so it's a tie. Obviously for crop this would make the Kenko the first choice, though it's not sealed.

But of course if the Canon mk3 fits the lens this and the body does f8 af this the one to buy, as stated with a tc every little bit makes a huge impact due it amplifies the lens' problems.

I do not believe there is a whole lot of difference in IQ, its not a factor.
 
The big factor is compatibility with Canon lenses.  Kenko has revised their TC's several times in the last few years to update them to be compatible with newer lenses.  this is undoubtedly due to incorrect assumptions made in the reverse engineering process.
 
The up side to Kenko is that it mounts with most EF lenses from almost any manufacturer.
 
Don't try it with EF-s lenses though!

Canon version works on most L zoom.  Not most L prime.  Kenko version works on both, yet not the 24 - 20L II.   :D

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.

The Kenko worked fine on my 7D. But, it is incompatible with several lenses with my 5DIII and the latest firmware, causing the camera to crash, requiring the battery to be removed to reset. The same has been reported by others.  Do NOT get the Kenko.

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.

 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 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.

I tried a friend's Tamron 1.4x on my 70-300L / 5D3 and it worked just fine.
Reading reviews of the Kenko on B&H and Amazon, it seems to work.

I have the 70-200 f4 IS USM Lens and have used the Canon 1.4 ll Extender since day one. I have some fantastic shots with that combo. You May not fill the screen but with cropping you will get better results than without it. I have used the 2X ll Extender and have gotten a good pic with tripod and using live view and my cable release on my 7D. But with the Canon 1.4 I can handhold and pan for BIF pics. Buy the Canon and as long as it's in good condition you won't regret buying it.

Kenko has revised their TC's several times in the last few years to update them to be compatible with newer lenses.  this is undoubtedly due to incorrect assumptions made in the reverse engineering process.

I'd say this is undoubtedly due to Canon screwing 3rd party manufacturers - with new camera bodies, they seem to extend the protocol or use protocol parts that weren't in use before and reverse engineering something that isn't transmitted isn't possible. Canon probably could go for better compatibility, but why would they :-p ?

3rd party lenses seem to work better, but you're correct and it for the user the cause doesn't matter - non-Canon tc's have these issues, and there seem to be some incompatibility with Kenko & afma on 5d3/6d.
