Friends,

I recently bought a 70-200 f4 and I believe that, for a little extra investment, one can have an additional 80mm reach for when its really needed. Since as, as is the case with many other 'accessories', Canon's prices are just simply ridiculous, I was looking at the Kenko options that are so highly regarded. Since I want to retain AF (I have a T2i), I will only look into the 1.4x at this moment.

I see Kenko offers two different products with EXACTLY the same specifications, and even almost identical verbal descriptions.

Can someone please explain (I have written to Kenko but they have not replied) what are the differences between the PRO 300 AF 1.4X DGX and the MC4 AF 1.4 DGX?

As I said, they are both current DGX versions, they have the exact same specifications, the only different mention on the PRO 300 is a minor phrase on being 'better' for primes, but then it goes on to discuss zooms as well.

Any input would be highly appreciated! Thanks in advance,
Rafa.

Hi, Rafael -
The Pro 300 Teleplus has 7 lens elements in 4 groups, and will be optically better than the MC4, which has 4 lens elements in 4 groups. The extra elements allow the designers to apply better correction for various optical aberrations. I notice that Kenko explicitly says their TCs don't work on EF-S lenses, but the 70-200 will do fine with it.

Kenko page at the THK US site (external link) for more information (you need to look at the specifications to see the 7 vs. 4 element specification).

Thanks a lot Jon!

I thought I had checked those specs to the last detail, but you have proven me wrong! :oops: There are, indeed, more elements in the PRO series, which will account for some image quality, for sure.

It also accounts for doubling the price! :( ... is there any place I could find a side by side comparison of the same lenses multiplied by the PRO300 and the MC4?

I am unsure if, at the price of the PRO300, it wouldn't be just a safer bet to get the Canon one?

Thanks again! Sorry for not have spotted the difference,
Rafa.

Might be some in here from the Lens Archive. But that's just a guess.

The Canon 1.4x is not compatible with a whole range of lenses at it had a protruding front element, so you'll need to be careful, it was really designed to compliment the long Canon L lenses. The Kenko will work with most lenses but the DGX model has some issues with particular bodies (350d/Rebel xt)

Thanks again Jon, I'll certainly dive inside that thread for information!

Thanks Lannes, yes, I didn't mention it but the lack of compatibility with the XT is part of the issues as we do share lots of stuff with my father and he is currently using the XT. The one lens we do have is actually compatible with the Canon 1.4x , so, on that front we would be clear, but, as you mention, most other lenses will not benefit from it. So, its kind of a crossroad: push for compatibility with actual equipment (go for Canon) or push for forward compatibility with probable future lenses and lose one of our camera's compatibility (though not sure if any more lenses will ever acquired :) ) and save some money in the process.

I'll need to give this some thought. Perhaps going for the MC4 will allow the further reach, not break the bank and work on one of the cameras with the current lens. The other options appear a bit too expensive for the compatibility issues of both options. Mmmmm... food for thought.

Thanks again Jon and Lannes for the helpful info,
Rafa.

It appears the electronics on the DGX is the part that is not compatible with the XT, the older Pro 300 DG model doesn't have the same problem.

As per Jon , the Pro 300 DG would still be better quality than the MC4

Since Canon introduced the newest converters recently, I don't know how Canons new TC's stack up against the Kenko PRO300 DG.

I did test the 1.4 mk2 TC against the Kenko 1.4 and the Kenko PRO 300 DG was better.

Thanks Lannes, I'll look into the non-X one for availability. I have read that those were the ones not reporting corrected focal lengths to the camera, though I'm not sure how that affects much outside flash photography?

Thanks Lowner for the feedback... I must confess I'm surprised... really? The DG was better than the Canon? That and even broader lens compatibility must be interesting! (also the option to use it on the XT). Did you use it with any IS lens? I read somewhere that they introduced jumping IS issues (though I can't remember if it was a one-case-scenario or a more widespread issue).

Thanks again friends, I really appreciate all the help, you make it so that when I finally decide to purchase, I'll have not a single ounce of remorse :)

Rafa.

check this thread out mate ... lots more in there
Kenko 1.4x TC Version Questions

EDIT ... and basically I would suggest you get the latest Pro300 DGX, it has far better optics than the cheaper model, more versatile than the Canon and arguably as good if not better than the Canon in terms of IQ, it won't disable AF quite so quick either ;))

Rafa,

"...really"?

Yes, there was a small but clear difference. but remember that was before Canon updated both TC's. I have no idea how they stack up today.

... the only thing that is for sure is that the new Canon models will not be cheap, and the Kenko is already only something like 2/3's the price of the Canon, so I guess soon it will be half price ;)

Something else to help ... when I was looking for a tele the best comparison I found was a German review of all the teleconverters lined up against one another ... luckily for me I can speak a fair bit of German, but I am sure if you don't, you can still make out roughly what is being said ... basically that the Kenko Pro 300 DGX wins out ;)

Thanks Lowner and damnit,

I definitely need to improve my search-foo here... I swear I looked for such a thread, and it was a very recent thread at that!, weird I did not find it. I was able to extract the most significant bits of that German article, and I have read through the other thread completely.

For what is worth, the new Canon 1.4x III was never even considered... If I'm going to spend $500 it certainly wont be on a teleconverter! I could purchase a used 70-300 IS for less than that amount and I have more reach, same aperture, and I keep the option of going to 70mm if need be.

No, it'll either be the MC4 DGX, the old PRO DGX or the new PRO DGX... both PROs appeal to me because of their quality, the old PRO appeals to me as it has compatibility with the XT, and the MC4 appeals to me because of the price. A used old PRO DGX may come into the MC4 price realm, so that is another option as well.

Thanks again for all the feedback and info,
Rafa.

NP ... and BTW - all the advice I read or was given said DON'T go for the MC4 as IQ will suffer quite badly - I also think that for the difference in price its probably not worth the risk, especially if you are planning on bolting it on to that 70-200 as I imagine you are.
