Has anyone used the Tamron AF 1.4 Teleconverter with a canon 400mm L f 5/6 prime? And are satisfied with it?

Sorry, I did use it on a Tamron 18 - 270 mm. It worked perfectly including the AF.

This combination has worked fairly well on my 30D (in direct sunlight). It works quite well on my 70D (even good enough for birds in flight). Link to some images...http://www.pbase.com/jekyll_and_hyde/with_teleconverter

I had the Tamron first. I got it because it had good reviews, a lower price, and IS. Bottom line: it was very soft and had AWFUL back focusing issues over 50 mm. I sent it to Tamron for calibration and it came back worse. I ended up returning it and instead of getting another copy of the Tamron, got the Canon. Best decision I ever made. This is the sharpest lens I own, including all my primes. I was told by Tamron that 20% of their 24-70s have focus issues on the Mark III (which I have) due to the Mark III's focusing system and the Tamron not being totally compatible with it. I have a 60D as well and the Tamron also had back focus issues with that body as well, although slightly less. I would not hesitate to recommend the Canon, bar none.

It will work fine with your teleconverter, but your max aperture will then be f/5.6....... with the 1.4 extender your max aperture will be f/4.0

I found it to be very slow focusing at distances of less than 10 feet, since the depth of field is so wide and the camera (Canon T3i) gets confused. Manual focus works better in those situations, and is quickly changed with the forward/reverse clutch of the focusing ring itself. Tamron lenses have a very tiny focus mode switch to hunt for.

I don't have the Tamron 70-200 but I have the canon 70-200L f4, and I must say the 24-70 Tamron is not as sharp as the canon. Having said this, the Tamron is sharp enough for me and in anycase you need wide-tele lens for general photography as opposed to long telephoto zooms such as 70-200.

The teleconverter works best with F2.8 lenses. AF may not work well at higher F stops and you may need to go to Manual focus

Thanks for the information. I was using a Canon 28-135 IS USM as my walk around travel lens and loved it until it got stolen in an airport! :-( Now I'm in the market for a new lens and I'm leaning towards the Tamron. I've used their lens in my past photography life with my old AE-1 Program and I'd LOVE the 18-270 if I can swing the $$$. I'm hunting eBay as well, as that's where I got my 28-135 and had NO problems with it at all!

I only use the Tamron AF 2X on Tamron lens only on the Canon body cameras that take only EF and EF-S lens. I use only Canon converter for the Canon lens.

Well, I don't have the Tamron but the Kenko is really good. I actually picked it over the canon 2x TC. I have the canon 1.4 X and they go great together and the Kenko retains AF wich the canon does not. You can't go wrong with the Kenko. Hope this could help somehow. Good shooting and keep making art.

I have the same lens & teleconverter and it works perfectly. Good luck hope you enjoy this setup. Wayne

Hi there. Being a bird photographer I can safely say I know the lens you have as well as this converter. It will work but the focusing will be slow. I would prefer either focusing manually or getting the 2.2x teleconverter lens that goes on top of your Tamron lens. If you need more information on that lens, email me again. Best regards- Charlie.

I have a 40D and plan a Europe trip with the intention of taking one lens, with the same choice. Questions are: Image quality at either end of the range? Macro quality, build quality? The utility of an additional 50mm of the Tamron?Critical perhaps is stabilisation with Sigma. Can anyone advise?

Have not tried the tamron the cannon 24-70 2.8L II . Is a a purchase I'll never regret. It holds up against my friends zeiss primes plus blazing fast auto focus

Yes. I struggled with the decision to buy the 2.0 TC or the sigma 50 -500 lens to get more zoom as 200 didn't reach far enough for my needs. In the end I got the teleconverter as it was less money and mainly a way to avoid another heavy lens. It works out very well. loss of sharpness and some f/stops as others have described but you will hardly notice. faster glass and more sharpness costs thousands of dollars which i'm unwilling to spend. i'm pleased going this way.

PD thank you for the great review. What do you guys think about the new Tamron 70-200mm ?

Yes it will work. Keep in mind that you are getting cheaper glass than if you were to buy Canons 2X teleconverter. I have used it with my 6D and the canon 70-200mm lens and it worked fine. I was in a natatorium later in the day so the light was not optimal for testing, but the focus was softer using the 2x, which is to be expected. Teleconverters work best with longer focal length prime lenses and tend to have more of a negative impact on image quality with zoom lenses. So your mileage may vary. If you don't need the full magnification of 2x and can live with a 1.4xm the smaller teleconverter should (in theory) have less negative impact on image quality. It was not too bad for me with the 2x but it was noticeable.

It should work for Fine with manual focus. I wouldn't expect autofocus to work at the long end. I forget the max apeture on the short end of the tamron but I would expect it to be slow auto focus at best even at the short end. The teleconverters are really best suited for fast glass (f2.8 for f4).
