lense sizes

I just bought a dvx-100a and I also purchased some extra lense filters. These filters are 62mm and used with an adpter sizing ring. Now when I look through them, my view is circular. I also got a .5x wide angle lense than has a very similar problem (its view is football shaped). Can this be fixed or shall I return these lenses?

Thanks
Larry

Sounds like you got "Digital Optics" lenses. Definitely return them, they don't work with the DVX and they're very low quality.

the filters are"Crystal Optics" and the wide angle is "Digital Optics". I take it I should also return the "Crystal Optcs"?

By all means. That stuff is *not* quality. Hope you can get your money back...

It sounds like you're describing vignetting, where the edges of the frame receive less exposure that the centre - and in extreme cases where the edges of the frame don't show the picture at all. If you've got a 72mm filter thread (you have) make sure you buy filters and converter lenses that are designed for that attachment size or larger. It's OK to use step-up rings (72mm to 78mm, say) but not step-down, and especially so with wide-angle converters.
