About Canon 1.4x

Extending a lenses focal length by a factor of 1.4x, Extender EF 1.4X III incorporates phenomenal optical performance with minimal chromatic aberration and is a perfect complement to many of Canon super telephoto lenses.

It features a built-in microcomputer for seamless communication among camera body, lens and extender; features careful lens placement and coatings to minimize ghosting and flare and even has a new Fluorine coating that keeps soiling, smears and fingerprints to a minimum.

An integral part of many professional systems, Extender EF 1.4X III maintains high standards not only optically, but also in terms of rugged, dustproof and water resistant construction.

Highly recommended

This is a significant upgrade to the previous version II. Highly recommended, especially with the new f2.8 300 and 400 lens from Canon Worth the money.

Most Liked Negative Review

 

Okay but needed more

Had wanted the 2X Teleconverter, but it would not available at the time, and let someone talk me into the 1.4 X. Just doesn't do what I needed it to do.

Canon Extender EF 1.4x III Tele Extender, USA by Canon

By

Excellent - used with 100-400 and 200-400 Canon lenses. Sharp as a tack with the lenses and autofocus works well

 
5.0

Better than I thought

By

I didn't have a lot of high hope but I wanted a tad more reach at times with a 300mm f2.8. Not only does this do the job , image quality does very well. Over all I am very happy.

 
5.0

Great Option!

By

Since moving up to a full frame camera from a cropped sensor, I miss the extra reach that the cropped frame gives to the lenses. This tele extender almost gets it all back - (1.6 vs 1.4) without a sacrifice to clarity and with only one f stop difference.

 
5.0

Noticeably faster than my ef 1.4x ii

By

The 1.4x II version is a very good one, but this one makes for noticeably faster autofocus.

 
4.0

good but overpriced

By

I use this with my 100-400 IS II lens and my 400 F4 DO lens. works well and is reasonably sharp, especially with the F4 lens. They charge too much for this product. It is way overpriced.

 
5.0

fine performance

By

excellent combination with the 300 f2.8L

 
5.0

Perfect for my BIF images

By

Very happy with the extender. Use it on my 300 L f4 with my 7D.

 
4.0

Worth the price

By

When I upgraded to a full frame sensor I missed the additional magnification. I had played with a 2.0 II extender, but found the IQ loss just too much. This pairs very well with a 5DMKIII and a 20-200 f2.8 LII IS lens. Obviously, not as tack sharp as the lens on its own, but a great compliment to get the extra 80mm of tele.

 
4.0

Pretty darn good

By

I hated my old 2x extender but still needed more reach on my 70-200 and couldn't afford the 300mm 2.8 lens yet. I read some other reviews and this 1.4 seemed pretty popular. Turns out, it's pretty darn good. The improvement over the 2x is stunning. The slow focus and softness are reduced to usable levels. I use this mostly for college football games and can still get good focus with fast action and the softness, which is noticeable still, is acceptable in the world of fast action. I would hesitate to use this for still life or portraits though.

 
4.0

works well with Canon EF 300mm f/L4

By

added to my Canon EF 300mm gives the additional magnification I was looking for in photographing wild life...loss of speed (reduced to 5.4) has not been a problem except in the early morning and late evening...compensated by adjustment in ISO...would recommend for wildlife shooting

Questions & Answers Powered by TurnTo®

Questions about this item:

Harry S  I am shooting with a Canon 6D. Want to use the Canon extender 1.4 with a Canon 70-300 mm F4-5.6 L IS USM. Will it be compatible. Will it hamper the autofocus? Will IQ be as good. How much will I lose in f?
RICHARD N  If you check the specs on the tele-extender it is NOT compatible. Since you lose one f stop with the 1.4 your lens would now be a F5.6-8. This probably takes it past any capabilities to use it sucessfully.
Harry S  Thanks Richard. I read the Specs. Its pretty straight forward as to what lenses will work and what won't . I felt that the 100-400 canon was to heavy for me to use. The images I took were OK but not razor sharp. I also had hand shake. The longer I was out the more my hand shook. I was hoping to get the 70-300 mm to fill in the gap with my 24-105, but I think I would miss the 300-400 for wild life. I wonder what Canon was thinking when they put out the 1.4 extender.? Thanks for your response.
