Q: 1. Will this work with a Nikon F2?

A: Yes, it is compatible with the F2.

Q: 2. Hello. If the adapter has a lens 1.4x, does it mean that a Helios 58mm in a Nikon D5600 will become in a 113mm (58 X 1.4 X 1.4) (correction factor of the camera and correction factor of the adapter)?

A: If you are looking for the 35mm equivalent focal length of a full-frame lens with a native 58mm focal length used on a Nikon APS-C sensor with the FotodioX Pro Lens Mount Adapter for M42 Lens to Nikon F Mount Camera, the new equivalent 35mm focal length would be 121.8mm. Your math was close, but in your (58 x 1.4 x 1.4) equation, you mis-typed the camera's crop factor, which is 1.5x. As such, 58mm x 1.4 would be 81.2mm, which is the equivalent focal length when using the Fotodiox adapter on a camera with a full-frame sensor, and you would then multiply 81.2mm x 1.5, which equals 121.8mm, which would be the 35mm equivalent focal length when used on the 1.5x APS crop sensor found in the Nikon D5600 DLSR camera.
