Previously I had posted on the Pixco Nikon G to Micro 4/3rds focusing helicoid, which filled a need in my UV-imaging setup. However, it does have significant play in the adapter which can affect the accuracy of fine focusing. Hence I decided to take the plunge and get the one from Fotodiox, which is said to be in their Pro adapter line. Continue reading Fotodiox Nikon G to Micro 4/3rds Focusing Helicoid – unboxing

This is a fairly thin helicoid focuser (unbranded) which I bought on eBay. It is probably amongst the thinnest helicoid focusers available, which could allow for mounting of filters between the lens and helicoid. Continue reading Helicoid focuser – thin M42 to Micro 4/3rds

This helicoid focuser comes as two parts: M42 to M42 17-31mm helicoid, and the short M42 (c-mount) to Micro 4/3rds adapter, which has 25.5mm and M42 female threads. This allows for use of 25.5mm filters, which can come in handy. Continue reading Helicoid focuser – M42/C-mount to Micro 4/3rds

Here I have the Nikon G to Micro 4/3rds helicoid; I also own the Nikon G to NEX helicoid. These allow for direct mounting of Nikon lenses to Micro 4/3rds and NEX; other helicoids require at least another adapter in order to mount Nikon lenses to a mirror less camera. I gather Fotodiox also make a Nikon to mirror less camera helicoid adapter, and I have made enquiries regarding their Nikon-Micro 4/rds helicoid adapter.

I will post about each helicoid focuser I have separately, and then combine them together for future easy reference. The information will include the various dimensions of each helicoid and my impression of how each works. This first post will be about the Hawk Factory M42-Nex helicoid.
