Trail camera Bluetooth works great
Night vision objects need to within 10 feet for good pictures. Daylight pictures are excellent quality 20 to 30 feet away. Motion detectors work great day or night

La mejor cámara
La calidad de imagen es impecable, funciona perfectamente bajo el agua y es muy fácil extraer los archivos en tu computadora, la única falla es la capacidad de la memoria, espero en un futuro se pueda expandir la memoria a 128 GB o más

Very easy to setup and use. Zero problems.
This device was impressive in all aspects. Price, setup, operation and reliability. One note: do remember to remove clear tape over the charging contacts (look for small read square to pull tape away from contacts) before attempting to charge.

Q
Is there a compatible additional lens for different magnifications and/or focal lengths?
A
The two built-in lenses are self-developed and currently not compatible with other lenses. 
Q
Is there an adapter with wide-angle function for full format from 24 mm focal length?
A
I use the pro square system with frames around the glass and have no problem with 24mm. 
Q
I have a Minolta lens, can i use this adapter?
A
Could you please update us your full Minolta lens model ?as Minolta has MD MC and AF mount, K&F Concept MD-M4/3 is suitable for: Lens: Minolta MD MC Mount lens(not for Minolta AF mount: KF06.157) Camera: Micro 4/3 (MFT) mount mirrorless camera like Olympus PEN, OM-D series, Panasonic Lumix DMC-G1, G2, G3, G10, GX1, GH1, GH2, GF1, GF2, GF3, GF5, GH4, Panasonic AG-AF100 Mirrorless Digital Cameras, Black Magic Pocket Cinema Camera (BMPCC) 
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
Does this adapter change the focal length?
A
An adapter does NOT change the focal length regardless of what is mentioned in the 1st answer. The adapter *can* be used on a camera with a smaller sensor which would change the filed of view of a particular focal length.
