Misleading description but decent adapter
First off, it's a nice looking adapter that serves the purpose of connecting your SATA and IDE drives to your PC, or maybe smartphone. The adapter housing is plastic but is well built. The data port to the adapter is USB-C. It comes with two cables that will connect from USB-C to USB-C or USB-C to USB-A. It also comes with a 12V power cable that you'll need when connecting a 3.5 inch IDE/SATA drive to the device that requires the 4-pin PWR connector. The device can be turned on and off with a small switch and it has a blue LED indicator when activity it taking place.The description, in my opinion, is a bit misleading. It tells you that it's USB 3.2 Gen1 (Older 3.0 designation at 5Mbps) and that may very well be true about the USB-C port, but the SATA connector is for sure SATA II based on my speed tests. Reference the attached pictures that show the speed tests. To be fair, it doesn't say anywhere that that adapter is SATA III, but it does mention 5Gbps speeds, which you aren't going to obtain using a SATA II connection. I ran a separate test with another SATA III adapter using the same drive and got very different results for read/write. You can also reference that in the attached pics.All of my tests were done with a KingSpec 512GB SSD with SATA connection. I didn't have any other drives laying around to test so I'm hoping that the other adapter connections are working fine when I need them later on.Overall, this a decent adapter but I would recommended it for data recovery and not for daily use, substituting this for an external enclosure that supports SATA III speeds. When I come across old (maybe even newer) legacy drives that I need to recover data from, this adapter will be very useful and is why I got it. Speeds won't necessarily be high priority in that situation. But, I feel as though it should support faster speeds as it makes reference to 5Gbps and that's why I have to take a star away. Decent product but know what you're buying before you do. 4 stars.

MK-7 works better for me than MK-4
Thought I'd add my two cents on this, hopefully it'll help. I first took this brand/form when I researched and realized how important it is to take both K and magnesium with vitamin D. Once I finished the first bottle, I accidentally bought mk-4 for second bottle. I didn't want to waste it so I took it and finished the bottle. I ordered mk-7 for the third bottle and can't say enough how much of a difference I've noticed between the two types for myself. MK-7 seems to make my joints feel better and I have better movement in places like my neck and back. As well, not sure if this is directly related to K, my muscles aren't as tight.So, for myself it would seem MK-7 is much more effective than the MK-4. Hope it helps.

Fits perfectly Sony RX100 Mk.III
Fits perfectly Sony RX100 Mk.III with a spare battery, SD card and a short charging cable. Hand strap is a little bit shorter to wear it around the neck but build quality is otherwise good considering pricing.

Seems to perfect in size for the Sony DSC RX100 ii
Seems to perfect in size for the Sony DSC RX100 iii for which it was purchased. By this I mean that it fits with a little bit of room to spare so no tugging to extract it etc. Even with the extra small compartment for SD cards etc this is still a sensibly small size case that is practical to wear on a belt without it getting in the way of everyday activities. It appears to be well made and good value.....time will tell.

Best 2x TC I came across so far, but don't expect
I use this extender with my 70-200/2.8, 300, 400, and 500mm tele lenses for wildlife shooting (hobby). My cameras: 7D, now upgraded to a 7D II, and a 5D III. Important in particular for 2x TC users: both latter cameras still provide an active center field autofocus with lens+TC combos that have an F/8 initial aperture. In particular every birder knows: you can't get enough focal length. And if you don't want to invest in - and carry - a super huge & heavy 800mm lens, you have to have TC's in your backpack. I use Canon's very good 1.4x MK III TC frequently, and less frequently this 2x TC. Many reviewer's here explained already the 2x TC's technical pros and cons in detail. In real life, according to my experience, you can break it down to those three items that really count:(1) images lose visibly sharpness and get softer, in particular in the edges (full frame) but with re-sharpening during post-processing (or sharper pre-settings in your camera) you can get acceptably good results (= you still can see feather/fur textures) IF...(2)... there is enough light available (!!) for a - with many lenses - quite slow combo AND...(3)... the object does not move too fast and unpredictable, because AF will work as sluggish as an old digital compact camera (but accurate with a carefully micro adjusted camera).This may also be important for you:- Oh no, you can't combine Canon's Mark III 1.4x with 2x TC's to shoot man's first footsteps on Moon from Earth. Canon prevented this mechanically, not only by some sort of pins (you could easily remove): the whole TC's do fit because their lens systems extend from their bodies and would collide before their bayonets snap together. Don't complain, be sure that the image quality of such combos would be too lousy anyway for modern high res sensors. If you need extreme focal lengths check if digiscoping (mostly without AF) would be the better solution for you.- Some lenses do not fit with Canon's Mark III TC's because, again, their extended lens systems would literally collide with the back lenses too close to the bayonet. The example in Canon's lens line that I presume is most prone to such a disappointment is the macro lens EF 100mm/2.8 L IS USM. So check the TC's compatibility with the lenses you want to use it with before you hit the order button. Btw you can pimp your macro's magnification by using extension tubes, plenty of good ones with full electronic supply of AF and aperture are available.Final word(s):Given the fact that a 2x TC is always a quite extreme optical compromise, the Canon engineers did a decent job with the Mk III version. But do not expect any wonders. An EF 400/5.6 lens will always be much sharper at 400mm - and focus much quicker - than a 70-200/2.8 II + 2x TC III combo, I can tell from my own experience.Those who just start with the TC business, I'd highly recommend to go first for Canon's 1.4x TC Mk III. It provides less reach but much better optical and AF performance. In practice you can use it much more frequently and get good results.

Q
Does the autofocus work with the Nikon lens on the Canon camera?
A
This adapter is non-electronic and so will not enable electronic communication between lens and camera, so no autofocus.
Q
I have a nikon d3100 camera and need an adapter to fit a minolta 75-300 lens. does this adapter do that are can you direct me to one that would?
A
K&F have a list of which adapter will work for each lens to camera combination they support
Q
will this work with the Sony A 6300
A
Will work with any camera that has the thread for a Tripod mount. As far as I know yes will work with the Sony as it as a Tripod thread.
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.
Q
Does this system work with an eos 5d mk iv?
A
It works with my 1Dx and 6D so I can't see why it wouldn't work with a 5 series body...
