Buying a sony hvr v1u, need an opteka fisheye to fit 62mm threads. My last dvx-100b had the correct fisheye threads (58mm i think) for the 58mm camera threads, however there was so much vig i had to zoom in... Wondering if i should do a 67mm opteka fisheye for the 62mm thread mount on the hvr-v1u with a step up ring to avoid the same problem. Has anyone on here used 62mm opteka for a v1u or z1u??
