About Tamron 2x

Teleconverters, either 1.4X or 2X, are efficient tools to add focal length to the photographer's arsenal. However, universal-type teleconverters have certain limitations in performance when used with ultra-telephoto lenses of 200mm or longer as compensation of chromatic aberration alone becomes highly critical in this focal length range. The new PRO-series teleconverters are specifically designed and optimized for use with such ultra-telephoto lenses to deliver maximum resolution, contrast and color rendition without degrading any aspect of the master lens performance.

The 1.4X teleconverter will increase the focal length of the master lens by 1.4X and make the lens one f-stop slower. The 2X doubles the focal length of the master lens and makes the lens two f-stops slower. In addition to increasing focal length, both teleconverters allow greater magnification in macro since the Minimum Object Distance (MOD) of the master lens does not change when used with the teleconverters.

The 1.4X teleconverter can be used with both AF and MF lenses. AF will be retained if the master lens is F/4.5 or faster. AF will be retained with the 2X teleconverter if the master lens is F/4.0 or faster.

The Tamron 2x is commonly used for Wildlife photos and more.The Tamron 2x is popular because customers like the following qualities of the Tamron 2x: Easily interchangeable and Lightweight

A Decent Way to Upgrade to Telephoto

Compared to buying a telephoto, using the converter is an inexpensive way to increase the focal length of my existing lens. I attached it with my Canon EF 50mm f/1.8II and had decent results-- although the auto focus does not work half the time. I have to use it on manual focus but that's okay. I tried it on my LensBabies Lens and it didn't work at all.

Well made but images not clear

By

from Sacramento CA  -  Photo Enthusiast

I used this with a D90. It fit well but difficult to get acceptable images. As the distance increased the fuzziness became more obvious. Returned after using for several days in many different situations.

Pretty Impressive!

By

from Lake Wylie, SC  -  Pro Photographer

I got the Tamron SP AF 2x converter for Canon lenses yesterday, and took it out to the woods today for some test shots,... and am very impressed overall. Today I mounted it to a Canon 70-200 EF 2.8 L lens and was very impressed with the speed of focus and overall quality. The auto-focus was very fast and sharp with just a press of the shutter/focus. The unit is all black, and seems well built. The Canon 70-200 is a long and heavy lens, but it still feels nice and solid with the Tamron SP AF mounted between it and the camera body. For these tests today I took the Canon 7d out. Below are a couple of test photos, all hand-held no tripod,... the ducks are from about 100 or so yards away, at 200mm (or 400 mm with the 2x), shutter at 200, f stop at 8, and 320 ASA,... the close-up insert is of the same pic but digitally zoomed in to see the detail. The pic of the fence is at the same settings, but at 70mm (or 140mm with the 2x),... focus was set on the birdhouse,... notice sharpness of the grain in the wood fence from the center of the frame to the birdhouse. I've also attached it to a 28mm all-manual Prime Lens and the effective doubling of focal length was nice, as well as the sharpness of image and blurring of background. Not a bad piece for the price!

Amazing Teleconverter

By

from Eatonton, GA  -  Semi-pro Photographer

I use it in bird and wildlife photography, and occasionally with my Tamron 180 macro. When I purchased it, I was concerned that my images might be reduced in sharpness. Boy, was I surprised. I coupled it with my Canon EF 100-400 and tested it extensively. What I learned is this: I get tact sharp images. I attached the 2x teleconverter to the Canon EF 100-400, on my Canon 5D MII, and mounted it on a sturdy tripod. I used live view to raise the camera's mirror to focus. I closed down the lens two f-stops to increase the depth of field. With the mirror raised, the camera would not vibrate when the image was taken. I used two methods: cable release and 10 second timed shutter release. For testing, I manually focused on a pontoon boat outboard 150 yards distance. See attached image. The lettering on the outboard is sharp and easy to read.

Works Great

By

from Chesapeake Beach, MD  -  Photo Enthusiast

Just got the Tamron 2X Teleconverter and used it to get close-ups of birds. It works well with my Canon 60D and Tamron 18-200mm telephoto. Have used it with and without a flash with no problems and good optical results.

Works great with Canon Rebel T2i

By

from Atlanta, GA  -  Photo Enthusiast

I use the Tamron 2X on my T2i with my Tamron 18-250mm and my Sigma 105mm Macro. I use it hand held and on my tripod. I lived many years without automatic focus, so that is not a problem. It is ease to don and doff, it just takes time.

What? Confusing way category is stated.

By

from Madison, Indiana  -  Casual Photographer

On a Canon xti model camera along with Tamron's 18 to 270 power zoom with I'm really pleased with. As other reviews have stated auto focusing isn't 100% with the 2X.

Not Compatible with EF-S Lenses

By

from Columbiana, OH  -  Photo Enthusiast

1st despite the adorama product image, this teleconverter is all black. Also, they failed to mention that EF-S lenses will not mount. However, it performs very well when coupled to my Tamron 70-200mm f/2.8, auto focus works just as it did without it and image quality suffers only slightly. I was going to buy the Canon 300 but for as often as I need that kind of reach, this works just fine for a fraction of the cost.

Questions about this item:

Shopper  will this work with canon xti and canon ef 100-400 lens?
MARK P  It will likely work but it will not autofocus.
Dave T  Does this work with a Canon EOS 70D body and a Canon EFS 18-200 mm lens?
DAVE K  It should although I haven't tried it. Note that it only autofocuses in a limited f-stop range. I have used it with a Tamron 18-270 mm lens on a Canon 7D and it performed as advertised. I was happy with the results. I hope someone has used the exact combination you are interested in and can give you better guidance.
rich c  I would like to use this with a Nikon d90 and a Tamron 18-270mm lens. I'm looking at wildlife and landscapes. Any thoughts on how it will work? I understand that I will have to manually focus it and will lose to 2 f stops, but can I still get decent pictures with it? Thanks
TONY T  Hello Rich C I had to opportunity to use my 2X teleconverter a few times with my Canon T2i with my Tamron and Sigma lens. The quality is good enough for normal internet use (email, facebook). I do not make large prints, so I can not comment on that. You will not get the quality of a pro 500mm, but the cost is not that high either. Happy Shooting
