2x Teleconverter battle - Sigma vs Kenko

[Nathan55428]

I have basically decided to get the Sigma 70-200 2.8, and want to get a teleconverter for it (its replacing a Canon 300f4L), but want a bit more reach than a 1.4x will get me. For the 1.4x converters, I have heard very good things about the Kenko, but not much about the 2x. I would assume the Sigma is better suited to the Sigma lens, but you never know.

And yes, I understand that the 2x won't be as sharp or as fast as the 1.4x.

Thanks

I used that combo in front of at D60 on these pictures. View them in "original size" for evaluation. They are not at all sharpened to their full potential. I used a mono pod for all images and I'm satisfied with the results.

I'd keep the 300 f/4 and just add a 70-200. Might want to consider the Canon 70-200 f/4. You would then have two excellent lenses instead of a good lense (if you get a good one) and degraded performance with the teleconverter. And you won't have to worry about rechipping the Canon lenses where you might have to get the Sigma rechipped. But, that's just me. Happy shooting.

Great question, why you wonder, but I have just ordered a Sigma 70-200 F2.8 and a 2x tele, this will compliment my sigma 300mm F2.8 and 1.4x tele I already own.

Interesting enough I also own the Kenko 2x tele and have used it with the 300mm F2.8 but have not been too impressed with the results. Assuming the kit arrives today I will try some test shots with both the Sigma and Kenko 2x Tele and let you know.

Have you been able to compare the Sigma and Kenko TCs yet? Would be interested in results. Thanks

I've used the kenko for several years now with my D30 and now with a 10D and have noticed just a slight degradation but nothing that would ruin your enjoyment of the pic.

Have a look:

I have a Canon 70-200 f4L with a 2x extender. OK, it doesn't autofocus but I don't find that a problem. What it does do is give brilliant versatility with no detectable loss of quality at a reasonable cost.
