My Hawk's factory adapter is really starting to drive me bananas. I like the idea of this adapter (the ability to focus closer than the far off minimum focus distance of rangefinder lenses is awesome), and it can generate some
good images, but it is now becoming a pain in the butt. There are three things that are now driving
me up the wall.
Firstly, as I mentioned in a previous post, the helicoid has
a bit of play.
Secondly, there is no lock on the standard position, so when
focusing with a lens that has slightly stiffer focus than normal, it starts to
adjust the helicoid. Very annoying.
Thirdly, and by far the most annoying is that the tolerances
on the M mount are a little off, and now my LTM to M adapter is jammed on. As it is a thin adapter, it is very difficult
to move. No matter what I did, it
wouldn't budge (and yes I released the lens lock first).
Given I paid $140 used for it, I am pretty ticked off about this purchase.

Looks like it's not easy to make a helicoid that has no play. I have had three brand new helicoids and all of them have some degree of play.
ReplyDeleteActually I think a properly machined helicoid adapter with very tight tolerances would actually be quite expensive - probably $200-$300. However lens manufacturers get this right with zoom lenses all the time, so it cant be too hard.
