Please only without UV protection filters or on the F-mount lenses

Clearly: this adapter brings Nikon F-mount lenses Nikon 1 mount.
Without big words about the meaning, purpose and limitations of this adapter to lose (because about every interested party is likely to have already informed themselves) I would like to address here on two points:

1) What lenses run with it?

With me running the aforementioned without any problems:

Nikkor AF-S 35 / 1.8, 40 / 2.8 Micro, 18-105 VR (which was also to be expected)
Sigma DC 50-150 / 2.8 HSM (in my version I)
Tamron SP 70-300 / 4-5.6 VC

The Tamron still brings to the J1 even at 300mm freehand super results, I am consistently surprised. Clear you have a little "practice" and internalize the settings, the problems and the handling, but it's really great!

2) My images are not something I'm doing wrong?

Quite simply, the lenses may no UV and / or protection filter be on it more! I had until I unscrewed with all these problems, the lenses filter.
The problems expressed in "double figure" of things out of focus, also focused the lenses does not clean or missed their targets although it has been shown that the focus is set correctly.

So super adapter, but no filter on F-mount lens! :)
