5.0 out of 5 stars Well Worth the Money but a Balancing Act With Light
By FloridaDrafter on January 12, 2019
This review is based on use with a Canon EOS 5D mark IV and the Canon EF 100-400mm f/4.5-5.6 L IS USM II lens. The Canon EF 1.4X III Telephoto Extender gives this lens a max of 560mm f/8, so you loose one full stop. To put that in perspective, from f/5.6 to f/8 (one full stop), you are only getting 1/2 of the light that you were getting at f/5.6. For me, there was a slight learning curve and it took some fiddling with settings to get good exposure in lower lighting.
The day I got this, it was one of those overcast days where the sun just looks like a smudge in the sky, but I just didn't want to wait for better conditions, and really, why should I? It was a pretty good test actually. Five of the shots I've attached were taken that day; the Downy Woodpecker (shot 2), two of the Eastern Bluebirds (shots 3 & 4), the Dove (shot 5), and the Tufted Titmouse (shot 6). My settings ranged from 1/200th shutter / ISO 1200 to 1/1000th shutter / ISO 800, and the darker images were at f/8. Most were taken under 60 feet away with the flying birds being over 150 feet +/-. All shots have been cropped to various degrees, but generally, I crop about 50% of the pixels away.
There is a wee bit of IQ loss, but nothing that you will notice on prints from 11x17"ish below and for general use, like Facebook, forums, and other places you might want to post images, even high quality. Once you convert to JPeG or other "lossy" formats, it's a moot point anyway. I am a "pixel peeper" so I did notice some IQ loss when zoomed past 100%, but honestly, how many people do that?. I don't see any color fringing or vignetting , even though that has been reported, however, I seem to concentrate on the subject, which I know will be cropped, so if it is indeed there, it's of no concern to me. I tested it, using the mentioned 100-400mm lens, on the 5D mark IV, the 7D mark II (See revision), and the Rebel T7i. All focus points worked on the 5D mark IV and Rebel T7i, but only the two center focus points worked on the 7D mark II. I tested in outside lighting that wasn't optimal. I was really surprised because reviewers have stated that you loose some peripheral focus points. Focus did slow down in low light on all the cameras I tested, but honestly, it wasn't that bad. Good lighting was a different story, all cameras AF was snappy as usual. Now, when Canon says the Canon EF 1.4X III Telephoto Extender will only work with certain lenses, it has nothing to do with optics or light, it just plain wont fit other lenses. For the heck of it, I tried to attach it to an EF 70-300mm f/4-5.6 L IS USM II, an EF 70-300mm f/4-5.6 IS USM II (non L), and an EF 100mm f/2.8 (I know, I just wanted to see), and it just would not fit the lens. The front element of the Canon EF 1.4X III Telephoto Extender went too far into the lens to allow it to attach.
This device will not replace a dedicated long lens, but it will sure improve your reach with very little loss in IQ. You just have to pick your lighting battles.

**EDIT August 28, 2019** My initial review stated that the EOS 7D mark II retained all focus points and though I can't explain how I missed that, you DO loose all but the CENTER TWO focus points with the 7D2, EF 100-400mm L II and this extender, i.e., the center focus point and the smaller one inside of it. You can toggle between these two, but no others are available. I suspect it's a sensor and firmware issue because the cheaper Rebel T7i has no problem dropping focus points with this combo.
I sincerely apologize if I've misled owners of the EOS 7D mark II.

5.0 out of 5 stars WARNIING: Have to do one thing when you get this for good photos
By Michael P. on December 5, 2019
As an amateur photographer who lives in Alaska and loves to shoot wildlife I was wanting this badly and finally grabbed it right before I went on a bear viewing trip.

Design: As with everything with Canon, these are really well designed and work perfectly. They even updated the color on these to help them match better with the newer version of the 70-200 and the 100-400, so that is a nice bonus. It is light but still has some good weight to it so you can feel the quality construction.

As for the use of this, it works perfectly with the EF lens series. I can also verify that it works with the RF-EF adapter on the mirrorless cameras. REMEMBER THAT THIS WILL MOVE EVERYTHING UP ONE STOP ON THE CAMERA and EFFECTS THE AUTOFOCUS POINTS.

MICRO-ADJUST THE CAMERA TO ENSURE BEST FOCUS or, like me, your photos will just seem to be slightly soft on focus

Cost: I purchased it for $340, currently $429

Overall: I am a Canon equipment user and this is just another in a long line of great products

Positives:
++Cost (but I got it almost 25% off)
++Design

Negatives:
--Autofocus effects
--F-Stop adjustment

Would I recommend: Absolutely/Borderline. Absolutely I would buy it again, borderline if you are not sure what to do with the other settings on your camera.
