Great Lens to Have In Your Collection
Extremely pleased with this lens for video and photos. I am using a Canon RP so I have to use an adapter but I am having no issues at all.

Fantastic Value
Fantastic value for the money. I got two, deeply discounted at around $10 each, and am still wondering whether the low price was a mistake. These would be worth it even at regular price. Very sturdy!I attached one to a Pentax K3 with no issues. The other went on my vintage Pentax 35mm, and for that I needed to use a standard hole punch to make the small hole in the little protective leather flaps just a tad wider. On both cameras, the straps hang just right.I am a short woman, and the length is just fine for me with no adjustments. I can either place it over one shoulder, cross-body, or around my neck. The reverse side is a soft suede-like fabric. I especially like how the part right where it hits my shoulder has extra padding.The color is a beautiful cognac brown and looks amazing. (My picture has pretty dark lighting.)I will report back if anything changes, but so far, so good!

Much needed QoL
There’s not much you can say about the adapter. I mean it works so what else would you expect? Well, it is well constructed and makes a nice click when installing your lens. I read some of the reviews on the cheaper alternatives and saw reviews mentioning the product feels cheap and how the lens are not firmly and securely attached. I rather not risk it but others have without issues. If you’re on a budget, do look at the cheaper alternative. If you can afford it then this is the one you want.

Adapter works fine
The adapter is good, delivery was also very fast, i got it just in 1 day.. But if you really wanna use EF or EF-S lens in mirrorless cameras, you have to keep in mind that the sharpness will decrease by a little amount and you you have to focus the subject very correctly, otherwise the picture will become blurry(specially for the prime lens)..

Excellent lens, quality build.
I am using this lens for Canon M50 Camera. You will need EOS adapter. I have attached 3 photos taken with this lens.

These are good!
These keepers are good. Arrived in time, and fit really well around the lens barrels of a Pentax FA 35mm, DA 18-55mm and even the Tamron 70-300 Telmacro. Everything as described, hope the adhesive spot sticks well on the cap.

Q
I need a dn filter and i have a 70-200mm nikon fx lens, does it work for me? thank you for your answer
A
I use one on a Pentax 24-70mm filter size 82mm. Just make sure you buy the right size for your lens. I have the nd1000, and I am very happy with result. They also sell adaptor step down for your other lens. 
Q
Will this work with the pentax mount asahi takumar smc 50mm 1.4?
A
Yes. I have the same lens and adaptor on my Sony a7ll and it works beautifully. The m42 is also known as the 'universal' mount as other 3rd party camera and lenses also used it. I own 6 other K&F e-mount adaptors to different lens makers (ltm, MD, CF/CD, Nikon) and they all are well built with a nice snug fit. Highly recommended. 
Q
Which M42 adapter should be used on your lens?
A

Please note: our M42 adapter ring could not be suitable for Pentax Takumar Super Takumar Carl Zeiss M42 series(aperture pin does not fully depress, small tabs sticking out), as ours depresses the aperture pin all the way down

 
Q
Pentax pk mount usually means pentax k mount which has a flange distance greater than m. is this adapter for adapting leica m lens to pentax q camera?
A
I actually have not received this adapter yet. It's shipping from China. Don't think that was disclosed in the ad. However, I do not believe this is for the Pentax Q body rather for digital and film cameras that take the Pentax K mount in its many variations. So I'm expecting to be able to mount my Leica M mount lenses on my digital and film Pentax K mount cameras, no autofocus or relay of exposure information, only to be used with manual focus and exposure. 
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:

  1. 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)
  2. 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.
  3. 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)
  4. 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.
  5. '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)
  6. 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)
  7. '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.
