Used Canon Extender EF 2x III Teleconverter E-

Ok the product is fine I guess not sure. Ok I  got Canon EF100-400 from another site so partially on me but thought there was a problem or something with this product and it auto not work tried find reviews but couldn't so I ordered it. I should have found out for shor funny after got review was first one when I searched it up after

Not sure don't do

It did not look as white as I was expecting it was a tan white like the older ones. Decent shipping. Have not really got to use it yet but heading out at end of month and will break it in then & leave a much better review.  Tanks

Not quite yet

Good

A great little extender which has added greatly to the combined focal length of my Canon 300mm f/4 combined with the Canon 7D, crop sensor-camera, for a total of 670mm with minimum aperture of f/5.6!

Adds no weight to my camera bag and fits easily into the smallest space. Does not seem to have slowed the electronic focusing down.

Tested it on a hike and made a great image of a Blue Heron perched upon a ghost tree. Love it!

Great Addition To My Camera Bag and the Canon 300mm f/4.

I bought this about one month ago, and I have only tried it with my old 5D Mark II. I'm not sure how well it works with newer cameras, but from what I saw it was NOT worth the $400 price tag. First of all, it is very limited in terms of which lenses you can pair it with. It is very easy to use, and convenient, BUT only works with certain L lenses. Secondly, as you probably already know, it cuts the max aperture you can use in half, so that REALLY REDUCES the effective speed of your lens, making it NOT a great choice for low light. The sample photso I tried all looked dull and blurry, NOT as sharp as the original lens itself. So maybe it's OK for ideal situations, on a very bright day, outdoors, where you can use low ISO and faster than 1/1000th shutter speed MAYBE this is a good choice, but otherwise I would RATHER just use a APS-C crop sensor to get a nice zoom result.

Cool item, but not for low-light (limited use)

great extender does what its supposed to do

great

Just have Patience when using this lens Extender.  Perfect for nature images. Not so involving sports images especially movement.  Otherwise, a great lens addition. :-)

Extender EF 2x III

I purchased this several years ago but have just started using it with my 70-200 2.8 lens on the R5. I'm amazed at how well this is working out and will be going to an airshow soon to see what images I can capture with the setup.

Lens Works Great with the 2X extender.

Works as expected. Still testing it out with neighborhood bald eagles. Darker and slightly less sharp than the 1.4x which is to be expected since you lose 2 stops of light with the 2x and only 1 with the 1.4. So far seems to work well with the Canon EF 600 f4 is usm III and the r3. Time with testing will detail for me whether it's a carry in the bag when I have monopod and tripod available. The loss of speed does mean I need some support help no hand holding with this connected.

2x Canon extensor so far works as expected.

Works exactly as expected. No better no worse. You do lose 2 stops of light and a small amount of sharpness but when you need that extra reach to get the photo at all it certainly comes in handy.

Meets expectations

Not much for 2X but the 1.4 is just a little tick without loosing quality. No problem with big glass/primes but do NOT recommend for 100-400 zoom, misfit.

No Sacrifice

Well was either going to try a X2 converter or buy a new canon 100-400 so for now I went with the converter, so far so good, everything is really good, pictures are still outstanding, I really can not say anything bad about this Len, have never liked using converters before but pretty happy about this purchase

Why not give it a try

Extender EF 2x III Is exactly what I needed to extend the range of my EF 300mm f2.8 lens. Auto focus works as it should although at slower response. That delay has impacted by sports photography but not my nature photography.

As always, Canon did a great job thought the order process and shipping. 

I am very satisfied.

LOVE this Extender EF 1.4x III - The photos have been amazing!

LOVE this Extender EF 1.4x III

The Extender EF 1.4x, the 3rd generation has excellent optics and produces impressive images (So does its 2x sibling. The purpose for using this extender to enlarge the subject matter in the image frame. Not to reach long distances. Atmospheric interference means any haziness, or heat haze will only be magnified.

This extender was designed for L lenses. It works superbly with the prime lenses. I have used it with the 300mm f/2.8 ver II, 500mm f/2.8 ver II as well as the 600mm f/4 ver II. 

In addition, I have used this extender with the EF 100-400mm ver II. The images this combo produces is amazing considering it is not a prime lens.

If your goal is to extend your reach so you can take pictures of distant subjects and expect a clear and sharp image, you will be disappointed. Even a prime lens with the extended reach will have difficulty producing a clear image due to atmospheric conditions. However, if you are taking pictures of subjects such as birds, or aircraft that fit 1/2 of the frame and wish to have images that fill 3/4 or more of a frame at distances that are not effected by atmospheric conditions, then you will amazed by the results this combination provides.

Note: on a zoom lens such as the 100-400mm ver II, your  f stop will become f/8 and therefore you will only be able to use a small portion of the autofocus points and in lower models perhaps manual focus will be your only choice.  This is where a mirrorless camera is the perfect solution as it will allow for use of all autofocus points. Also, because of the additional reach, you will need to increase your shutter speed and expect slower autofocus acquisition in low light.

This is an excellent addition to ones photography tools, but needs to be used in appropriate conditions.

Excellent Optics - However, most misunderstand how to use an extender!

Incredible extender. Fast shipping. I trust Adorama with all my major photography purchases.

Perfect extender with excellent service.

It appears to not be sharp at least at 4.0, 4.5, 5.0 and low apertures. Not surprised as I have had a few 1.4x extenders that have also proven to not be sharp. Very annoying...It may get sent back after I run a few more tests.

extender 1.4x lll not sharp?

CANON ROCKS

Sharp image. Minor complaint is that I didn't consider that I wouldn't be able to open up my 70-200 to 2.8 with the extender on. Other than this miscalculation on my part I'm pleased with this piece of equipment.

Happy with my purchase

Shooting with a Canon 6DMk II, and both of my L series lens 100-400 and 70-200, with the larger lens hard to track and focus on my subject (aircraft) loss of F/stops and quite dark. The 70-200 and extender faired better but still in the long run I wasn't happy with the addition and returned the equipment to Adorama.

Just average?

great photo results. A lot of focus points are supported through this extender for the 70-200ii

great product

Without this extender the EF70-200 would not be worth my time as it doesn't go out far enough.   This has helped considerably.

2x Extender

so far, so good, works well with 600mm prime lens

version three 2X extender

I upgraded to the 2X lll converter and it performs without flaw.

This upgraded Canon 2X converter elevates my photography to the next level

The Canon Extender EF 1.4x III has worked very well so far (I haven't used it extensively yet).  I use it with the Canon 400 mm f/5.6 lens and the extender couples well to the lens and camera, physically and functionally.  I have noticed that occasionally, the auto-focus will not work well.  Also, the focus point s are reduced to just the center.  However, this all is better than another extender I used before.

Works well physically and functionally

Great online and costumer service experience!!

This is a beautiful doubler - yes, I said beautiful because it works so well with very little diminishing of image quality. Solidly built and true Canon quality.

High Quality doubler

Excellent Quality.  Very useful.  Better Image Quality than using the 2x and loses only one stop of light. I have used it on the canon EF 400 f2.8, EF 500 f4.0 and EF 100-400.
