Matthew Duclos says:
"The CP.2 lenses are the exact same optical design as the ZF.2 lenses with the exception of the aperture blades. The aperture in the CP.2 is a more round, cinematic style aperture. They also limited the maximum aperture throughout the CP.2 range in order to keep the lens set constant which meant taking the lowest common denominator, except for the 18mm. The other reason they did this was to make room for their Zeiss CP.2 Super Speeds which do not have a limited diaphragm and will open all the way to T1.5."
MORE LENS OPTIONS THAN EVER

Lenstest_Kamerawerk did a series of comparison tests of the Sony CineAlta PK6 series PL mount primes against other brands in 2014:
"With this lens-test report we would like to provide a comparison between the new Sony SCL-PK6/F CineAlta PL Mount lenses and other state of the art products such as Cooke S4, Zeiss Compact Prime and Arri Ultra Prime lenses.
...Conclusion The tested Sony SCL PL Mount prime lenses have shown great imaging characteristics.
Contrast performance, sharpness and chromatic aberration are equal if not even better compared to its competitor lenses Cooke S4, Arri Ultra Prime or Zeiss Compact Prime.
As illustrated in the figure above, SCL 135mm, 25mm and 20mm actually show best mean MTF characteristics of all lenses!
All together, we have to say, Sony SCL lenses are a fantastic choice, for a low price!"

"I have a set of these and i’ve been extremely pleased with them. Affordable price, sharp wide open, no breathing and a fairly neutral look. Only downside is their weight. [deleted] I've shot with them a few times with the F65. I really like them. Sure, they're heavier than say Cooke minis or CP.2s, but they have a solid feel to them and are smooth."

"I used them on a Ursa Mini Pro this last weekend and didn't see any issue."

"They're not bad. They don't look overly-crisp, but they're still sharp. The flares are an odd green color as I remember.
F2 on the 135mm is quite a sight!"

"I use these (SCL-P35/50/85) on my FS7 with a Wooden PL adapter. ...I had them looked at Talamas in Boston and they are on the warmer side. It was compared to a 25mm CP2 that I have and they were on par. They are bulkier than the CP2 lenses, but I like their look."

"…The Sony primes, btw, are largely better than the Zeiss CP2s. The CP2s are a big mixed bag image quality wise, just because Zeiss took a bunch of stills designs they had hanging around from the last 15 years and repurposed them. Any Zeiss that started out as a cine design from the last 15 years is much better (Variable Primes, Ultra Primes, Compact Zooms, etc)"

"Definitely the CP.2s... Definitely NOT the sonys. I work with the cp.2s all the time and they are fantastic. Great bokeh, very sharp, very lightweight, lovely image, rent easily. I've also worked with the sonys... They can make a nice image BUT they are unreliable. They don't travel well. The internal focus mechanism gets knocked out of place easily. My local rental house in atlanta had to go thru 3 kits before they were sent one that was acceptable. They are very heavy in comparison so docu work is gonna be a pain. Between the two, go CP.2 without a doubt. I would also check out the canon primes, they looks great in tandum with the sony color science and I've also heard good things about the xenon primes but I'm still waiting on my demo. The cp.2 35mm superspeed is probably my favorite. The 85 is also fantastic, great for interviews. And the 135 is just an awesome lens. The 50 I use the least."

"In a side by side comparison on image quality the Sony's and the Ziess CP2's are neck and neck - But the sonys are substantially heavier - I have used them for a while and have never encountered the issues that are stated above but that doesn't mean they are untrue. Based on how they seem to be built i would think they are alot more durable and battle ready in comparison to the CP.2's. The 135mm is a very nice piece of glass for those super slomo beauty shots (Especially in 2k center scan) essentially turning the 135mm into a 300mm - Really the choice i would think here is if your looking to put emphasis on renting them out it may be more difficult to rent the sonys because of brand awareness with lenses. Also if your willing to lug these big guys around for your shoots."
I got a set of the early Sony T2.0 PL mount PK3 primes at a good price. On the 85mm, the focus ring turns to an 11mm protrusion from the flange. On the 50mm, the focus ring turns to a 13mm protrusion from the flange. On the 35mm, the focus ring turns to a 15mm protrusion from the flange. On all 3 of my these 35mm, 50mm, 85mm T2.0, MODEL SCL-P35T20 S0P01132, SCL-P50T20 S02P009744 and SCL-P85T20 S03P02096 PL mount lenses the flange of the PL mount is 1.9mm wide at the base, with a taper on the inside edge. It does not fit the Bezamod PL mount adapter for my Blackmagic BMPCC 6K or my @ Pro PL mount adapter for my BMPCC 4K. It will not rest flat against the mount. My other PL mount lenses have a flange thickness of 1.7mm, without as much of a taper, just a slight chamfer. The edge of the tapered flange on the Sony lenses look like they are slightly thinner or the same thickness as my other Duclos Cine Mod PL lens. This stainless steel Sony flange is held in with 8 screws, so it could be removed and replaced easily if the correct flange could be located. Sony charges $291.88 for this PL mount assembly.
EDIT - I tried my early plastic housed 35mm, 50mm and 85mm Sony CineAlta SCL lenses on my Blackmagic URSA Mini Pro 12K and they fit in spite of the close tolerances of their mounting flanges.
All of the Sony PK3 lenses have a the↓10↑: RoHS symbol, which I thought meant that it has lead-free solder at first, but I heard that a Nikon tech said a "10" in a recycling logo stands for a particular type of plastic, just as any other number does. It means that, when you do recycle it, you need to recycle it with "10" type plastics. I'm not sure if the PK6 lenses have this RoHS symbol.
EDIT2- I received my Mk II Sony CineAlta PL mount 25mm and 20mm lenses. They have no RoHS symbol, but have a square symbol. They both fit on my adapted BMPCC 6K and URSA Mini Pro 12K. The 25mm SCL-P25T20/F SN F20717 has a flange protrusion of 17mm. The 20mm SCL-P20T20/F SN F10724 has a flange protrusion of 17mm and is a tight fit on my Bezamod deep mod PL adapter. The inner flange diameter is 58.4mm on the 25mm lens. The inner flange diameter is 58.5mm on the 20mm lens. Unlike the Mk I lenses, there are no electrical contacts to relay EXIF data, the focus throw is 240 degrees (not 90) and they are much heavier due to the all aluminum barrels (2.3 kg.).
