    Tamron TC-X20C-700 reviews

    Teleconverter 2.0x for Canon EF is rated 3.9 out of 5 by 15.
    Rated 5 out of 5 by from Of course it Doesn't Had to write a review so that prospective buyers don't get misled by all the It doesn't autofocus reviews. There is nothing wrong with this product. It transmits lens information to the camera just as it is suppose to. When used with a lens such the 150-600mm G2 it produces a min aperture of f/13. It's not the lens that can't autofocus. It's the camera. There are no DSLR's made to date that focus at anything past a min aperture of f/8 and many can go past f/5.6. Strap this baby between on your tamron 70-200mm f2.8 G2 and you'll have a nice telephoto zoom of 140-400mm f5.6 with snappy fast autofocus. If you ask a fork to be a spoon you're gonna get soup in your lap. Same with this piece of kit. It doesn't work miracles but it does what it's suppose to - double your lenses reach.

    Rated 2 out of 5 by from To: W Scott That combination of lens and teleconverter will never work in the auto focus mode. The mid-range camera that you currently have, cannot autofocus with an F stop larger than F-5.6. With that combination and the variable aperture of the lens, you are already at a F-14. The 5D Mark 3 and 4 along with the 1DX Mark 2 have the capabilities of focusing with an f8 lens. A 1.4 teleconverter takes up one stop of light. A 2X teleconverter takes up two stops of light. That's why Canon suggest fast glass, like a F-2.8 when operating a 2X teleconverter. With that combination manual focus is your only option. I hope this helps you.

    Rated 5 out of 5 by from Auto focus works This isn't a review but trying to answerW Scott's issue with the auto focus. Cameras have issues auto focusing at smaller apertures, f/8 and smaller. The 2x will make the lens jump from f/5-6.3 to f/10-13. Most Canon cameras can only auto focus to f/5.6, with the exceptions of some of the advanced bodies, xxD (70,80) and the xD(1,7,5 etc) series which can auto focus to f/8. Using the 2x converter clearly puts that lens past the capability to auto focus with the camera. The 1.4x would of been a better choice if that's what you needed, albeit you wouldn't be able to use the long end because that would push it to f/9. But there is a way to get this combo to work. You can switch it to Live View and auto focus that way, again not the best for fast moving subjects but at least it'll work in Live View mode. Always a reminder to read your camera users manual start to finish, it may sound silly, but it's really useful! Also, look at the manufacture's website, it'll actually tell you some of this information as well (if you go to the Tamron site, navigate to this new teleconverter and scroll down, you'll find the 150-600 G2, click on it and voil)! I hope that clears that up!

    Rated 4 out of 5 by from Great Optics, Optically a 5. design 3.5. usage 3. I have never seen such crisp images from a tele converter. Excellent. THE Lens mounting lever is a BIG negative. constantly bumping it and dislodging the lens. Have wrapped an elastic band around to restrict the action. Usage : Auto Focus works but slowly, and only if one is in the rough range of focus. I'm using it on my 70-200 2.8 (Which is also a marvelous piece of equipment.) on my 7D and &D Mk11. So the 5.6 diaphragm should be better. Having spent several days working with it I am Happy with performance but disappointed in the mechanics.

    Rated 5 out of 5 by from an excellent companion to my 150-600 G2! first thing you need to know is that your aperture will be 2 steps smaller. I cannot comment about the new 70-200 f2.8 because what I have is the 150-600mm G2. with this lens, the effective maximum aperture will be f10, which is smaller than most cameras can handle for autofocusig. you can still use manual focus or liveview autofocus if you want the camera to focus for you. that said, it means that (with the 150-600) you won't be able to use it for fast-moving subjects or wildlife unless whatever your photographing is standing still and you have the time to focus. image quality is actually very good. at 1200mm a full moon will mostly fill and aps-c sized sensor! I've been able to get very nice shots from the moon as well as airplanes cruising at 38,000 feet! you have to keep in mind that this inmense reach will also augment heat distortion when shooting distant subjects. this is not fault of the teleconverter. all in all, I just love my teleconverter. I enjoy using it. once you know its limitations, it can be a very fun to use and a nice adition yo your lens!

    Rated 5 out of 5 by from Works great It works fine with my Rebel T3i and Tamron�70-200mm f2.8 G2.� Autofocus works just as well as the lens without the teleconverter.� The image is sharp out to 400mm handheld.� �I'll add a couple photos taken at 400mm with autofocus.� Both photos have been cropped.

    Rated 1 out of 5 by from Watch out. I purchased this teleconverter for the 2.0x magnification and didn't notice it doesn't communicated, when it comes to auto focus, with the Tamron SP 150-600 mm F/5 - 6.3 Di VC USD G2 lens. With only manuel focus, it makes following a moving subject near impossible. It also makes hand holding the lens for a distant shot very difficult. The only way I would use this teleconverter is with a tripod. I would have returned it had it not been damaged in a fall. That they released this Teleconverter, with this limitation, makes no sense because it only works with the new lens.

    Rated 4 out of 5 by from 2X Works in Manual Using this with the Tamron 150-600mm G2 only works in manual. But here is the result.
