Lens adaptor infinity focusing
Like all Four Thirds DLSR camera, my E-420 can be used with all my old manual M42, PK, CY or even Exakta or Voigtlander mount lenses via suitable lens adaptors. Except for the top quality (and hence more expensive) adaptors made in Japan or Germany (which I have not got the chance to use yet), most adaptors do not focus correctly at infinity. Instead of turning the focusing ring to infinity, I need to turn the ring back for a small amount. I kept a record here for self reference:
For Four Third – M42 adaptor made by Pixco working with M42 – Voigtlander adaptor (unknown maker), Voigtlander Color Skopar X 50mm F2.8 lens (serial no. 5766359) focus infinity at 20 metre setting
