Helicoid adapters Fuji->M42 and Fuji->Nikon F mount?

[wolan]

Hi,
are there helicoid adapters for the fuji mount you can recommend me?
I bought a cheap one but it does not focus correctly at infinity...
The Kipon adapters are very good but very expensive as well.

Thanks.

I don't shoot Fuji, but my experiences with µ4/3 might help, so...

The µ4/3 to M42 helicoid I got is (by my calipers) just 0.1mm too long for infinity!
I've not tried yet but I hope it will be possible to remove one end & lap it down slightly - turning it into a very useful adapter
Another possibility is to get a short M42 adapter (I've found them for µ4/3) and add a M42-m42 helicoid (these are available in a good range of lengths...

At one point I was considering a helicoid with a much wider lens mount to allow a recessed adapter to be installed as a DIY exercise. The µ4/3/EOS helicoids I've seen more recently proved to be an easier option to adapt.

I bought a "Tinray" one for Leica M> Sony FE which has no issues. If they make one for your fitment I don't know but it might be worth a search.
