Tamron 1.4x AF Teleconverter for Canon EOS - U.S.A. Warranty

I used it on a trip with the 90mm Tamron. The converter boosted my reach to 126mm. I was very happy with the boost and the image quality.

A very useful boost for my Tamron 24-70mm lens on my Nikon D850. Although there is a slight loss of sharpness, it takes very careful examination of the images to notice this.

It does not work on a Tamron 100-400 di VC USA lens and a Canon 7d Mark II. Neither Canon nor Tamron have any idea why. The minute you turn the camera on, a firmware update message appears, when you press OK, it says lens firmware is needed. Problem is, there is no firmware update for the lens, and the Canon is 1.1.2. May wind up with a third party converter from Amazon...

Talked to a person on live chat. They said this is absolutely the one I had to have for my setup. Did not read on my lens at all. Had too send back and only got refunded when I paid. I am supposed to have the pro 1.4 they say now.

I've got Canon 1.4 and 2.0 but neither of them would work with the Tamron 150-600 so I purchased the 1.4 extender from Tamron. It works. I've got it on the 150-600 and haven't taken it off. Auto focus on my Canon 1D MK III works well with it.

The Tamron 1.4x PRO Teleconverter is a handy way to get a little more reach out of your L series (EF) lenses with little to no degradation in image quality. I personally haven't noticed any loss of quality but I also haven't run any in depth tests. It WILL NOT attach to the EFS series lenses though. I've used it on both my 7D-II and 5D-IV

I AM USING THIS TELECONVERTER WITH A TAMRON 150-600 G2 LENS - IT WORKS AT ALL FOCAL LENGTHS MAINTAINING AUTO FOCUS - PICTURES ARE SHARP

Perfect addition to my Canon 100-400mm lens. Gets me up to a whopping 570mm equivalent. And it's small size fits easily into my otherwise "busy" camera case/backpack.

Added to my 400mm canon lens on my 7D Mark II. Really gives me a good reach to where I couldn't before without compromising quality. Good buy for the price to compliment what you might already have in your bag.

Makes a fast 50 mm into a great portrait lens. I use it mostly for wildlife and landscape, but have also used it to make a long tele into a VERY long tele for sports. Used carefully, it makes a remarkably sharp pairing with a quality lens. The photos have excellent central sharpness, and only a little falloff at the edges, but this is rather nice for closeups. It centers the eye on the subject. For use on Canon cameras, be sure to mount it to the lens first, then attach both to the camera. If attached to the camera first, the exposure results can be variable.

This is a very nice teleconverter, which is light, handy, and easy to use. It provides excellent results when used within its capabilities. Like all 1.4X teleconverters, it diminishes light transmission by 1 stop, but with today's digital cameras, that is no real problem. If the effective f-stop drops below 5.6, you may lose autofocus, but not autoexposure. Note! With Canon lenses, it is almost always necessary to add items to the lens stack before connecting the stack to the camera. If you attach the converter, then the lens to the camera, they may not work properly together. Though not quite the quality of the very expensive Canon dedicated converters, this does a great job for most purposes, and I think it will be a good value for use with the 100-400 Canon L Zoom.

After reading many reviews about the 2x and the 1.4x Tamaron Teleconverter, I tried both. As the review comments stated, the auto focusing on the 2x was quite slow and not acceptable for me. The auto focusing for the 1.4x was much faster and acceptable for me. I will only use the 1.4x Teleconverter for very specific long range photos, so the slower auto focusing will not be a problem.

The autofocus works perfectly with my Canon 600 , and 70-200 2.8 lenses. I also use it with a Sigma 500. I had 2 sets (and 2x) for Sigma and Canon, NONE of them worked for autofocus. These slow the focus down very slightly but tolerable. They work GREAT.

I was quite pleased by the quality of this teleconverter. The auto-focus did slow down a little bit but nothing to worry about. Good product for a good price!

I use it with the Tamron 70-300 VC, a VERY good lens. The teleconverter is equal to Canon's on my Canon 5D Mark II. I did find that the AF was a bit slow but not a real concern.

I used this Tamron 1.4 X extender with my Tamron 18 - 270 zoom on a Canon 60D, and the results were just what I would have expected - moderate but acceptable effect on sharpness. A good addition for occasional "long shots.." Yes an excellent 120 - 400 zoom would yield superior results at a cost of $1,000, but for less than $150, a great alternative for that once in a while need. Also, light and easy to carry. If you must have auto focus and image stabilization then go for the big bucks option - I come from the time when neither was available, but photos were still sharp.

Most teleconverters are not very good at retention of image quality. This one is. Compared to others I have used, it is remarkable.

To ensure proper function, as is true for most Canon lens focal length extenders, it is always best to attach the extender to the lens, then the pair to the camera. Attaching the extender to the camera, then adding the lens may result in improper function or focusing.

STEPHEN S.

Easily attaches to my Canon 400 mm lens but cannot autofocus with my 50D. Still, provides clear pictures and is a great value compared to purchasing a 500 mm lens.

My opinions of this extender are something of a mixed bag. Optically, I think the 1.4x extender is quite good and is a useful addition to my bag. IS functionality is retained on all the lenses I tried. On the other hand, I'm disappointed autofocus fails in many of my lenses. Specifically, 50mm f/1.4, 100 mm f2.8L IS Macro, 200mm f/2.8L all hunt for focus even when they are wide open. The hunting seems to continue indefinitely. Manual focus works fine and the camera detects critical focus being achieved. Rather bizarrely, autofocusing my 17-40mm f/4L works fine - even though it should not. Go figure. Something else that's odd - the model in the photograph is off-white. Mine is black. Maybe that matters, maybe not.

It's great!I used the teleconverter with Nikon 300 mm/4 AFD on Nikon D80, D200 and D300. Majority of the results were crisp and sharp provided lens was stopped down to 5.6 and higher. At wide open images appeared a bit soft particularly at the corners. It works nicely with 70-200 VR. I failed to discover any notoceable flaw. I would be happy if the actual f value was displayed in the viewfinder. So far as I know, Tamron Tamron SP AF 1.4x PRO is the only pro teleconverter for Nikon AFD.

I heard about this little gem from a photographer on Pbase.Considering the cost it performs admirably better than I had expected.I use this with my Canon 400 5.6 L lens for bird photography.It still maintains autofocus reasonably well,although it tends to hunt a little.Flight shots are more challenging but possible especially if the bird is large.Photos come out nice and sharp but you must use good technique,a tripod is recommended.This has become an invaluable tool for me and gives me the kind of reach I need for a very low cost.I shoot even small birds like sparrows and warblers.Highly recommended! Bird photography within the reach of us mere mortals.

TC 1.4 works brilliantly with 90mm tamron and nikon 80-200 2.8 nikon. A friend tried it with his 80-400 VR and was blown away with the ease and quality of the convertor

Vera

Works with the Nikon 70-200 f/2.8 VR lens - the big $1600 one - even though Nikon will tell you only their TC will work with it. Make sure you get the grey Pro version (which I believe is made by Kenko but carries the Tamron label).

A good buy. I do reccomend this but if you are planning to use it for very high quality professional use, or your lively hood depends on it, I might go with the major brand. I understand it is a little sharper. And more expensive.

It was very useful for taking photos of birds and other animals, used with a telephoto nikon 300mm lens f4.

This is the most versitile addition you can add to your bag. It fits the largest variety of lenses, while maintaining auto functions using lenses up to f/5.6 without problem. I use it on a Canon EF100-300 f/5.6L, Canon EF 400L and Canon EF100 2.8 USM macro without noticable loss of detail. It is suggested when using with macro lenses, to use manual focus which is common at high magnifications anyway. Considering the price of long glass, it's the best bang for the buck around! Get it, you'll be glad you did.
