About Tamron 1.4x

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.

One reason why the Tamron 1.4x is popular is because of its Lightweight

Bird photography within the reach of us mere mortals.

Pretty Good, You Get What You Pay For

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.

Dandy Teleconverter at a Great Price

By

from Bradenton, FL  -  Semi-pro Photographer

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.

It Works!

By

from Bradenton FL  -  Semi-pro Photographer

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.

Works as advertised and reviewed

By

from Texas  -  Casual Photographer

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.

Tamron SP AF 1.4x Pro Teleconverter for

By

from Murrysville, PA  -  Semi-pro Photographer

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.

Surprisingly pleased

By

from Hobe Sound, FL  -  Photo Enthusiast

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!

Great buy!

By

from Hobe Sound. FL  -  Semi-pro Photographer

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.

Nice alternative to a longer zoom

By

from Arden, NC  -  Photo Enthusiast

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.

Great Value and Excellent Optics

By

from Bradenton, FL  -  Semi-pro Photographer

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.

Good Value

from Houston, Texas  -  Photo Enthusiast

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.

Questions about this item:

Prince B  Will it work with a 7D and the EF S 55-250mm 4-5.6 IS ?
JEAN C  It will not work with ef-s 55-250 mm lens
Shopper  will this extender work on my Canon 60D and Tamron SP AF 70 300mm f/4-5.6 Di VC lens? or is there a better choice like the Canon 1.4x Teleconverter Version II? thanks...
STEPHEN D S  Should work fine, but your lens is a bit slow, so you may need to focus manually at the 300 end of the spectrum and in low light. Auto exposure should be fine, though. Just be sure to fasten the converter to the lens before mounting to the camera to get accurate exposure coupling. The Canon converter is better optically, but at a considerable price penalty.
Tim K  Will the auto focus work for Canon EOS T2i body with Canon Ef-S55-250mm?
OLE H  I have a Canon EOSD and it works GREAT with the Di Tamron SP 70-300mm f/4 - 5.6 lens I brought at the same time
