Has anyone here compared how the much cheaper Canon WD-58 performs against the likes of Century and Optex? Is it truly "zoom through?" Does it introduce CA or any other nastiness?

Also, what diameter is the front of the WD-58? Could the Century/Croziel/CAvision/Optex matte boxes be easily fastened to a WD-58?

Thanks.

Hi Brendan,

Please you the search function in the upper right corner. These adapters have been talked about and compared several times in the past. I believe the WD-58, is a 58mm thread size. I've not seen one of those adapters on a WD-58, but I'm sure through the use of step-up rings and adapters it could be accomplished.

You're right Jeff, sorry. I have been making extensive use of the search feature, but must've used the wrong parameters.

Also, while the threads are 58mm, the end is much, much larger. That's what I was really enquiring about as to whether it'd work well with the matte boxes. It looks like it may be somewhere in the 80mm range, but I need verification.

Thanks,.

The century Matte Box is rail mounted and barrel diameter isn't critical. the gap between the lens and the rear of the matte box is covered bt a soft rubber "donut"

Cavision and Chrosziel 4x4 clamp ons both have step down rings to fit the canon and the optex lens barrel. Both companies have a full line of screw in and split ring style adapters.

So, in your estimation, is the Optex worth the additional $120+? (or is it even more?)

Thanks

In my estimation it was, mind you my judgement wasn't really that scientific. I have a sony and liked the bayonet mount . the filter threads were also a plus. I had "heard" that the optex was sharper, but no official testing has been done to my knowledge.
