I'm looking into the Kenko line of teleconverters which I have heard good things about. I'll be using it on my Tamron 70-300mm VC. After looking on B&H, I noticed that there are two versions, Teleplus Pro 300 DG ($200+) and Teleplus MC4 DGX ($120ish). The Pro says it is compatible with EOS digital cameras, the MC4 says for EF lenses. Is the MC4 an earlier version, less capable model, or not even compatible with my Tamron? It just seems odd to me that the one designed for EF lenses would be cheaper, unless it is just an earlier version. Not sure if it is worth skimping and getting the cheaper version and risking worse image quality. I was just hoping there were some people who could provide some insight on the Kenko equipment. Thanks!

I have the Kenko 1.4x Pro 300 DG and it works fine.

I just ordered the Kenko 2x MC4 DGX from the below for testing on the Canon 70-200 f2.8 MKII due to the excellent results folks have received with the Kenko 1.4 MC4 DGX :

If interested order from Amazon direct & not 3rd party.

Here are some Extender testing results performed by a German website but you can easily decipher the findings and take note of the Kenko 1.4 MC4 DGX rating here:

Regards whatever your decision, ;)

I'd steer clear of the mc7. There are plenty of reviews between the mc7 and pro300 variants, and it's pretty across the board that the pro300s are superior. The tamron 70-300 vc is a pretty good lens, and I'd recommend buying the good TC, which you'll end up using for other lenses as well.

I would look to eBay. Pro300 DGX ones can be had for under $200 (both 1.4 and 2x)

I'd try to borrow one and make sure you don't loose AF since the lens you're going to use it with has an aperture of f/5.6 at the long end.

thanks for the input everyone.
silver, thanks for that website. it shows the MC4 as having better quality than the Pro 300 though (different than a Pro 300 DGX?) seems kind of odd to me unless there is a newer version of the Pro series, which I assume would be better. Is the Pro 300 truly different than a Pro 300 DG or DGX?

Also, I should state I am much more concerned about the optical quality than the ability to accurately state the aperture or FL. If the optical qualities are the same and I am just seeing improved circuitry, I'd rather save my money.

I've already decided that I am ok with having to manual focus if need be and I don't know of anyone I could borrow any equipment from unfortunately.

The MC versions have one less element in them compared to the Pro versions. The difference on that website is more a function of the fact that it is DGX versus the DG - DGX is the upgraded generation over the DG.

Thanks for the clarification wunhang. I would be safe in assuming that the 300 DGX will then outperform the MC4 DGX?

The one thing i have found about extenders is they are lens sensitive. One model might work fine on a 70-200 F4 IS like the Kenko Pro 300 DG and not be the same IQ wise on a different model lens.

The DG & DGX models are identical optically & element count & only had the circuitry upgraded to report properly to the bodys.

The cheaper MC4 models may be proving to be good due to having only 4 elements thus having a less light fall-off %. Who knows ! Just theory on some folks part.

Good Luck whatever your decision. ;)

I have the Kenko 1.5x (don't know the model), works on the Canon 500 and 100-400. It cost ~$90. I use it anytime I have either lens attached.


Everyday use: 7D2, 1.4x v3 Canon TC (sometimes the 2x v2 Canon TC), Canon 500mm f4 L IS USM; 6D, 24-105L

Thanks for that heads up about different lenses 'optical compatibility'. I guess I will give the MC4 a shot with the idea that it may be a little hit or miss. If the image quality is suitable then it will be great, if not then I'll give the Pro version a shot. Really looking forward to some better moon and wild life pictures!

Thanks for the help everyone, much appreciated!
