Barry, i loved my 40 and it focused very well, however friend got one parallaxed by loop and it was not the same, never snapped it.
very easy to re parallax yourself, and a little turn on the front lens makes a huge difference.
both varied in fov too, which was a little odd
do you have familiy / friends in the us ?? as no us stockists will mail them to the uk.
i can help if you dont
