Prime Circle Lense

[BrandonChristensen]

Is there tutorials on declicking?

I'd love to do it to my rokinon's.

Watched/read what I can find, but there can be issues with slackness and springs etc apparently that is making me wait till I have the time to buy some either buy some UGLY versions of KEH and experiment, or can afford to pay Duclos or RPlens to do it for me.

The last I heard, the Duclos Cine-Mods are $250 per lens. This includes de-clicking the aperture, 80mm front and a derlin focus gear. So for a little more than the price of the Prime Circle order, you can have your lens professionally modified, and not have to guess at what you're doing. Of course you are welcomed to rock out with your own mods, if you are mechanically inclined and are of brave spirit! Rock on!

wow these look great and F1.4 sounds damn sexy, would love to see some tests shot on Epic with these babies ^^
the back end and aperture rings make me think of nikon lenses.

They're just Zeiss ZF's. I'm sure there are many samples online.

I was curious and had read as much as i could find about modding my own zeiss zf's. I was nervous about screwing up my lenses, but then someone commented in a thread: 'real men de-click their own lenses' :-) and the rest is history.
I really can't speak for all lenses, but the Zeiss ZF turns out to be child's play!
- unscrew the back mount using a good phillips screwdriver
- take off the mount carefully
- the aperture ring comes off easily, observe how the ring is oriented for easy re-installation
- there is one tiny bearing stuck in the wall of the lens, just take it out (and save it if you want to reverse the mod)
- use a silicon based grease, to lubricate the aperture ring at the ribs, don't overdo it though > i ended up using a teflon lube for the boating industry
- screw it back together, the aperture mechanism has to fall into place, observe the spring mechanism falling into place as well
- you just added the ability to end a scene with an iris-out!!! and can call yourself a man (if you are that is)

Would love to hear Matthew Duclos' opinion about these.

Same method works for the Rokinon. Took less than 5 minutes.
