The lens was an EF 28mm f/2.8 wide open (that's a plain non-telecentric design as far as I know). Hi W, yes, I use an Opteka achromat.

I don't recall if you had the achromat, but that will help reduce (not eliminate) the vignetting. What lens are you using - if you have it stopped down to below f2.4 then the vignetting will be worse. (I have always had excellent results from my Vivitar zoom lens, even when stopped down to well below f3.5.) Worley Hello Eugenia,

Mine was literally the last adapter Worley made before he closed shop, and he said that he was out of Canon screens. So he used something else. I don’t think mine is a Canon.

You could switch to the ee-a. Very little vignetting. If you switch to a custom ground glass like Alex MD's then you'd need a condenser lens. IIRC Worley uses the canon ee-s.

The current one is way too grainy IMO. I think I just need a better ground glass. The current one is way too grainy IMO.

That's why they always bring up ring 3 in the HV20 forums when it comes to achromat + diy adapters. I think you just need spacers.
