: I am turning in an order for VX-2000. Need your expertise on best wide angle lense adapter. Thank You all.

If only .7X is tolerable, the choice is easy: the Canon WD-58, around $180 +/-. It is very sharp to the corners at most stops and zoom settings, and it is very low in flare and ghosting on the VX-2000. Wider, good (but not as good, and with very limited zooming range before focus is impossible), cheap, and light is the Sony .6X VCL-ES06 (it needs a 58->52mm step-down ring, but it does not vignette even so). Only one of my many cheap Series VII fisheyes works well with the VX-2000. I'm still waiting for a good zoom-through .5X and a good full-frame fisheye...
