I have the v1, it is very nice as long as you stay up to iso 400, 800 works ok in b&w
The18.5 f1.8 is very nice, sharp, low distortion , low CA
10mm f2.8, only ok in comparison to the above, but very small
and 10-30, I have not used it for a long time, the aperture limts the speed specially combined with an iso up to 400, the vr it has is not good at all, I do not recommend it
I also have the FT1 adapter and I use many of my f mount lenses with this combination, it takes patience but it is fun, amazin reach and good quality when combined with the consumer fx 70-300 vr zoom
Since you dont have any lens the 18.5 would be my recommendation
