SkaliwagifyOh cool! Which ones do you have? Can you give me a bit more on your experience with them/how you're using them? Not to get off topic of the thread.
I have the 25 2.8, the 50 1.4, and the 85 1.4. I also have a zf 35 f2 to fill in the gap because the C/Y 35 1.4 is really expensive (I'll get one some day).
I bought these custom 3D printed focus gears from followfocusgears.com, which are really nice and pretty affordable. Also got 80mm fronts from Cordvision.com with push-on caps, and got them declicked by RPLens.com. Basically they're fully cine-modded for less than half the price of what Duclos would have charged.
I've only had them a couple weeks, and I've been using them on an a7s. I mostly shoot narrative, commercials, and music videos these days so I decided it was time to invest in a solid set of matching primes. I haven't shot anything serious with them yet, but just from fucking around testing them I love the whole set. They're really solid and smooth mechanically; they all have 180 degrees or more of focus throw. Optically, they're not quite as sharp or perfect as modern zeiss glass or even L primes, but they're plenty sharp for my liking and I personally prefer the little bit of vintage character and warm color tone. They do still have that T* coating though, so they flare really nice and have that sexy Zeiss microcontrast, especially stopped down a bit.
If you're gonna invest in a decent set of primes for video, I'd say either C/Y Zeiss or Leica R glass is the way to go unless you can afford CP.2s or Schneider Xenons or something. The ZFs and ZF2s are nice but the Nikon focus rotation drives me nuts. I can't wait until I have the money to replace my ZF 35 f2 with a C/Y 35 1.4.
