Yes...(if you are talking about the pro line TC)
Sigma, Tamron and Kenko pro series are all made of the same Hoya glass. All are way respectable when it comes to sharpness.
I had my Kenko Teleplus Pro on my 70-200mm 4L just today...no second thoughts about slapping it on.

ED: Kenko's are the least expensive of the bunch if you find on ebay (ship from hong kong) BHPhoto had em (Kenko Teleplus Pro 300 DG) listed for @ 189 the last time I checked, my buddy picked one up on ebay last week for 129 shipped.

| Can not speak for the Tamron, but the Sigma 1.4x works on the 70-200 and the EXIF data (and thus the camera) is aware of its presence, despite being a third party TC. |

| ya, i was looking at it after getting the lense today, cause the reach is good, but just outa reach for inside surfing action. but, i had a quick question on whether you guys really felt the extra 80+ mm was a huge deal + the 5.6fstop. would u say its a great price to pay? but for 129 id say youd have to be crazy to disagree. but, i was just scared that the performance would be fed. peace |

Perfomance on my Kenko is great... and the +80mm is almost a must for airshow and such if you don't have a bigboy.
You say surfing is what you will be taking? People are smaller than planes I'm thinking you really need the +80.
I got some surf comp on the disk here somewhere from Cardiff that I used the 70-200mm + kenko TC and I had a ND4 on it as well, I'll put a couple up here somewhere. 5.6 is plenty open for that kind of shooting unless an absolutely gray day (and it still would be fine). Handheld you will want a minimum of 1/300sec which isn't tough in sun at the beach. |

| If you dropped that much money on the Canon glass, why wouldn't you get the Canon teleconverter? I would...... IF I were to get a teleconverter (I should sometime I suppose) |

My reasons are because the Canon TC is almost $150 more and it will only mount to certain "L" glass lenses.
Sure the Kenko, Tamron and Sigma pro line TCs are not water sealed but they will mount every lens except EF-S and they are near as sharp.
Just took this one... 70-200mm 4L + Kenko Teleplus Pro 300 DG x1.4 = 280mm

| Good answer! I would only use it on my 70-200 so I was thinking pretty narrowly |

I have the Kenko 300 Pro DG version of the 1.4. I use it on my 70-200 2.8 and also my 120-300 2.8 alot. I find that it degrades the image just a touch but as long as you shoot tight and dont crop alot you dont lose much. I compared the results to a canon and I cant tell much of a difference at all. I bought mine on Ebay from a Hong Kong seller and paid like $140 at the time shipped to me, took a couple of weeks to get here but was worth the 70 dollars or so I saved from buying through my normal source of B&H.

Edit to add, 280mm isnt really a long enough lens for shooting surfing. Most use at least 400mm and several use 600mm those are more standard lens for shooting surf.

For what it is worth I use a Tamron pro 1.4x quite often with a Nikon 70-200 f1:2.8 VR and get pretty sharp shots. All TC's are going to reduce quality a touch to quite a bit. The Tamron Pro 1.4x gives me sharper shots than my Nikon 1.7x TC.
