Canon EF 2.0 Mk III Telephoto Extender
To say I was apprehensive of purchasing this tele-converter would be an understatement. After owning the Canon EF 2.0X mk II and being completely disappointed and underwhelmed with it, it took me years to decide to try another 2x extender. After I did purchase it a few weeks back, it even sat in my bag a week or 2 before I decided to pull it out and try using it.With a tool like this, you want to use it for the right reasons and on the right kind of lenses. With that said, I'm using this on the Canon 300mm 2.8mm professional lens. Because the Canon 300mm has a smallish range, I've always shot with the Canon EF 1.4 MkII telephoto extender tacked on the back of it. The 300 is such a sharp lens, I lose very little sharpness using the 1.4 tele. Being a bird/wildlife photographer, I am always looking for more and more MM, so I decided to go ahead and try it.So far it's been everything I was hoping for. Much sharper than the 2.0 Mk II with the addition of new coating on the glass, this rugged and now very sharp tele didn't disappoint. Without doing any scientific study I would say this is at least 50% sharper, and at least that much better with contrast than its older counterpart.As always Canon L pro equipment is built like a tank, with dust proof and water resistant construction, it keeps up with the Pro L lens standard. The Mk III appears a bit smaller than the Mk II and the "white" coating has changed with the Mk III line of lenses, so the color is a bit different on the outside.Though I still have tons of shooting to do with it, so far I love it, and though it is high priced, appears to be well with it.As with any additional glass added to your lens, you really need to learn how to shoot with this tele. Forget hand holding it, use a tripod. Also because this is a 2X extender, you're losing a LOT of light. With my Canon 300mm 2.8, with the 2.0 mk III I'm now shooting at aperture of f/5.6. You're also losing a LOT of autofocus speeds. Canon is saying as much as 75%, but it didn't feel that high. So you need to use this lens in good to great lighting, on a tripod using already good Canon glass.Ricky

Do not buy an 82mm lens cap or hood. That size is
The threading of the filter for the lens cap or threaded hood is not 82mm. I just purchased an 82mm lens cap and hood only to find out it is too large. Looks more like it needs to be a 73mm to 75mm thread. The 72mm thread for my lens is correct, however, and works well.Update 11/4/2020: Ordered a 77mm to 82mm step up ring. The ring fits and means that this is a 77mm thread and not an 82mm thread for the cap and hood. If you buy this filter, you will need a hood and lens cap for a 77mm thread.

Usable, but not as pictured.
The phone holder sent was not the one in the picture and only has the threaded adapter on one end instead of on both the end and the back.

works well but...
you need to figure it out. the camera adapter should be screwed on vertically, not horizontally. Look for a 2nd threaded mounting nut. The remote location should be adjustable for different size hands.

An Overall Good Kit
The disappointment was the petal hood. It is threaded though only outside and is not reversible. The locking ring which comes with the hood is useless as the hood needs to keep loose allowing the photographer to maintain hood alignment with the frame. Also, in the hood there are no inside threads which means you cannot use the lens cap. Cap use is debatable, but if you prefer using the cap, you will need to remove the petal hood.I did not buy this kit for the hood, it just seemed like a nice bonus. I will most likely discard the petal hood and get a reversible.The quality of the lens cap included with this kit is a bit rough, though it works and would be an acceptable replacement if you accidentally loose an original cap.Everything else in this kit is decent, and does what they are supposed, for the most part. And all at a price that is great for getting started with experimentation.

Only macro lens works, not tele lens.
Mixed results. Comes with a macro lens for closeup zooms and a tele lens. I created a side by side comparison in the accompanying picture collage. The iPhone could not focus on a close up of my laptop shift key. The macro lens zoomed nicely but gave a fishbowl effect. When I used both lenses with the iPhone, the fishbowl went away. Finally, I included a picture of a pen tip and penny, so you can see the type of zoom you can get. With the tele lens by itself, I could not see any improvement in regular photos, not shown here. Still worth it for close up pictures.

Q
Only try all K&F tripods? Can other tripods be compatible?
A
Can be compatible, the threaded interface is 3/8 inch tripod can be applied.
Q
Can the lens cap be directly attached to both lens and filter?
A
Yes, the lens cover is magnetic also threaded, and the lens can be screwed on directly, or it can be magnetically attached by a magnetic attachment ring or filter, which is a two-in-one function;
Q
Can it be mounted on a tripod?
A
Has a 1/4 threaded connection for use with a tripod
Q
will this work on all K & F tripods? I have the tripod with the ball head? Thanks!
A
Yes. It works just fine on mine.
Q
Why camera indicated “lens is not properly installed”?
A
If your camera indicated "lens is not properly installed", please modify the camera menu settings. Usually called the "release the shutter the lens is not installed", you can modify the settings to allow. Specifically refer to the camera manual.Following are some examples:
-
MFT（M4/3 mount camera）'Lens Not Found' - Warning Message Appears
For Panasonic Lumix:
The camera needs to be set to function without a MFT-Mount lens attached. You can do this by changing the following camera setting:
'Menu' -> 'Custom Menu 5' -> 'Shoot W/O Lens' -> 'On'
(Exact naming and location of this option may change depending on camera model)
-
Fujifilm X mount camera, The camera needs to be set to function without a GFX-Mount lens attached. You can do this by changing the following camera setting:
'MENU' -> 'SETUP' -> 'BUTTON/DIAL SETTING' -> 'SHOOT WITHOUT LENS' -> 'ON' (Exact naming and location of this option may change depending on camera model) Choose ON to enable the shutter release when no lens is attached.
-
Sony E mount camera, 'No Lens Attached' - Warning Message Appears
The camera needs to be set to function without a E-Mount lens attached. You can do this by changing the following camera setting:'Menu' -> 'Setup' -> 'Release w/o Lens' -> 'Enable'
(Exact naming and location of this option may change depending on camera model)
-
Nikon 1-Series mirrorless camera , 'Check lens. Pictures can only be taken when a lens is attached' - Warning Message Appears
With a Nikon 1-Series camera (such as the J2), you will need to make sure the camera is in 'Manual' exposure or shooting mode and the focus selection is also set to manual. When in any other mode the camera tries to take control of the lens which is not possible as the adapter does not have any contact with the camera circuitry, so you get the lens check warning as the camera does not think there is a lens attached.
-
'EOS M mirrorless camera ,'No Lens Attached' - Warning Message Appears
The camera needs to be set to function without a EF-M Mount lens attached. You can do this by changing the following camera setting:
'Menu' -> 'Custom Menu' -> 'Custom Function 7' -> Select 'Release shutter w/o lens'
(Exact naming and location of this option may change depending on camera model)
-
Konica Minolta:
For Konica Minolta and "No Lens Attached"
Custom Menu 3
First item "Shutter Lock"
Set it to "Off: no lens"
(Depending on camera model "Shutter Lock" May be in different menu location)
-
'Samsung NX 'No lens.' - Warning Message Appears
The adapter is designed to trigger a sensor inside the camera body itself so no setting needs to be changed. If the error message is coming up with one of our adapters attached, then it is possible that the adapter is not hitting that sensor the way that it should. Usually rotating the adapter slightly in the mount, or un-mounting and remounting the adapter clears the problem with no further action needed. If that doesn't solve the problem, then the best course of action would be to swap out the adapter you have with a replacement.
