Adapter for Micro 4/3 (Panasonic G1)
These are a micro four thirds adapter (lower left) and M49.8 extension tubes. While they works with any telescopes, adding 7157/7158/7159, you can use EOS, Nikon or Pentax K lenses with Panasonic G1 camera. These adapters allow to reach the focus at the infinity distance. Yes, they can be used as parts of Borg M42 system as well. We will detail about the configuration at Hutech site. Since G1′s flange back is really short, I believe theoretically any other brand lenses work with G1 as long as adapters are available. Some should be available soon. I think short flange back gives optical engineers more benefits to ease lens design. Panasonic is the best aspherical lens producer. They have developed their own 3-D measuring instrument for that. Probably this story surprises many people. They have been deeply involved in optical indusry since the past. Many Japanese lens suppliers including Canon and Nikon rely on such a Panasonic optical production capability.
