So far so good
We bought this to keep an eye on what visitors come around our chicken run at night. So far it’s picked up cats and deer. Seems to work great thus far - had a few months already. I’d buy it again!

Great!
Works great! I recommend getting the touch screen version though, it doesn't cost much more and is worth the extra.

A good purchase
Excellent night visionCamera works great! The connection is a little slow at longer distances, but it doesn't affect usability. Setup should be pretty easy for the experienced, I was using it for the first time and thankfully my husband figured it out quickly.

Q
What is the difference M42 Series Lens to Sony E Series Mount Camera, M42-NEX IV PRO High Precision Lens Mount Adapter and this adapter?
A
Hello, the appearance and design are different, but the functions are the same 
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
Will this adapter allow me to mount a fujinon m42 55mm 1.8 and a sigma-z m42 135mm 2.8 to a sony a6000?
A
HI your fujinon m42 55mm 1.8 and a sigma-z m42 135mm 2.8 are M42 mount, the item can fit your camera and lens
