DVX100 Century Fisheye on HMC150

[Ryan Galvan]

I have a DVX fisheye adapter from Century that has a chunk of glass that was broken off when the front lockring came lose and the glass fell out one day. This break is not viewable on the image so I luckily could still use it. I recently upgraded to the HMC which has the same bayonet as the DVX but slightly thicker so the DVX fisheye would fit very tight and over time would likely break the HMC mounts. Seeing as I would no longer be able to sell the broken lens yet it was still useable, I took the DVX fisheye and machine shopped myself a custom DVX100 fisheye that fits on the HMC by moving around the lock ring on the inside. My question is on the HD fisheye lens made by Century for the HMC/HPX or the HVX is there a difference in the glass? I have a working fisheye now but I am wondering whether or not I am losing any quality. Thanks.

Test it with a resolution chart, or a real life situation where you could see the difference. If your satisfied, then it is good enough.

When talking about the HD fisheye for the HMC/HPX are you referring to this lens?

Because I guess this one is really different from this one:

So which DVX fisheye do you have? And can you post some pictures of your setup, I'm interested.

possible you could be losing sharpness

I am using this fisheye (although cracked).

instead of upgrading to this one:

there are actually a couple nicks visible on the image in the right light i noticed but still not too bad.

I will post up some pics and clips later tonight.
