Currently I'm using a Canon Elura 90 with a step up ring(34-37mm) and hoya filters. Previously, I had the Kodak Retiner 0.6 WA lens and it worked fine with just the ring. However, when I used the ring, a filter(uv or polarizer) AND the WA lens, I had serious vignetting issues. So, I returned it.

Also, I use the "widescreen" option on my Elura which changes the aspect ratio to 16:9, thus causing more vignetting.

Basically I suggestions on what lens to buy that will allow me to use it with ring+filter+16:9 without vignetting.

Thanks alot.
