Related Questions and Answers

Q: 1. Will the PL mount hit the internal ND's of an Alexa Mini or the new Burano while focusing?

A: The NiSi ATHENA Prime T2.4/1.9 Full-Frame 5-Lens Kit (PL Mount) have not been tested with the new Sony BURANO 8K Digital Motion Picture Camera (B&H # SOBURANO). There is no interference, however, the distance is really close for the ARRI ALEXA Mini LF and Lens Mount Set (LPL), B&H # ARALXMLFM. The full length of protrusion on the rear element is 25.5mm.

Q: 2. Will the NiSi ATHENA Prime T2.4/1.9 Full-Frame 5-Lens Kit (PL Mount) clear the RED RF-PL eND adapter?

A: Quoted directly from NiSi, regarding the clearance of the NiSi ATHENA Prime T2.4/1.9 Full-Frame 5-Lens Kit (PL Mount), "We have never tested this, but my suspicion is that it would not be compatible."

Q: 3. Do these lenses cover the 33x44 sensor of GFX cameras? Or, are they intended for crop video shooting?

A: Yes, the NiSi ATHENA PRIME 40mm T1.9 Full-Frame Lens fully covers the entire sensor.

Q: 4. Can the Nisi PL Mount lens be adapted to EF mount? For example for C500 mark 2? I don’t see a Nisi adapter but maybe another will work?

A: No, NiSi ATHENA Prime T2.4/1.9 Full-Frame 5-Lens Kit (PL Mount) nor any other PL mount lens cannot be adapter to the Canon EF mount because of the flange distance issue.

Q: 5. Do these lenses (PL mount) have any issues with the Z Cam eND module?

A: We have not tested the Athena PL lenses with the Zcam and are don't know if there will be any interference with the focusing on the rear of the lens.

A: The PL mount version of the NiSi ATHENA Prime T2.4/1.9 Full-Frame 5-Lens Kit have not been tested with the Meike RF PL Adapter with ND filter. NiSi has just released a similar adapter for these lenses, which is the recommendation for the same use.

A: The NiSi ATHENA Prime T2.4/1.9 Full-Frame 5-Lens Kit is made of aluminum construction.

[46.0 mm] Love this thing for my vintage M42 lenses. Made by a company that also makes amazing manual primes, which is why I decided on this one. Great price too!

[FUJIFILM G] The results of the Anamorphic lens on the R5c are amazing. The lens has the right amount of sharpness. The bokeh and the lens flares add a nice look to your film. I plan on buying the 75mm version when it is released :)

[Full Frame] Love this lens! But I have it setup with the DJI Lidar RS as well and haven't used it on it's own outside of basic testing.


The lens itself is very nice - solid construction with a decent front loaded weight, and an easy enough to balance shimming system for mount swapping. The glass offers a lot of character with minor fringing and fairly low distortion, get it for that classic softer cine look and don't expect it to be the cleanest/sharpest lens around. I personally love how it rolls off the highlights and still gives details in the skin but also a bit of softness, when paired with my c70.


All that said, I bought this lens as part of a whole setup to solve a specifc problem, and for that purpose I couldn't be happier! I shoot mainly with a c70 in solo operating conditions as a b-cam op. This lens not only solves most of my focusing issues, but it also serves as the fastest setup with it's auto calibration feature when paired with DJI's Lidar RS. Now I get a decent jump in hitting focus while in auto via the Lidar mod, and I have the added benefit of more unique cine lens look vs my native Canon DSLR glass. It's awesome, and has performed perfectly for me so far! I only wish that they'd release a wider 21mm Cyber or maybe a 16 or 18 instead.

[T1.9] Corner & edges sharpness improved a lot. Turn m42 mount lens into full-frame with good overall image quality. NICE!

[T1.9] Surprisingly amazing little anamorphic lens. Sharp & full of character when paired with the Red Komodo.

[T1.9] Wanted this locking Filter Frame to replace the non locking Holder Frame on my S5 system, and it attaches and works perfectly.

[T1.9] .I would characterize myself as an amateur filmmaker, or at least a serious hobbyist, who has had no experience with cinematic lenses. This lens was an absolute blast to experiment with. It's a solidly built metal body, with smooth-turning geared focus and aperture rings. It is manual focus, but with the use of focus peaking, very sharp images can be achieved. Not coming from a cinema background, T-stops are a bit mysterious to me, but the wide T2.9 aperture (which I've read is roughly equivalent to f2.1) allows lower ISOs in low light conditions. A nice bonus is the inclusion of a lens pouch. For an example from my first shoot with this lens, visit https://youtu.be/462z64lIzUc. I look forward to playing much more with this fun lens.

[T1.9] These lenses are phenomenal for the cost. If you've worked with a variety of the more budget-friendly cine lenses, you'll tell the difference as soon as you hold this lens, but then you'll be blown away as soon as you see it through the monitor. I've been putting my gfx100ii with one of these lenses in the hands of my filmmaker friends and asking for first impressions and watching their response echo my own says it all.

[7.5 x 5.5 x 5"] There are so many budget cine lens options out there, but rarely do you get a reasonably priced EF mount cine lens with smooth gears, solid as a truck metal build, that goes up to T2 AND has macro capabilities. This whole series from Sirui is fantastic. I own the 50mm and the 35mm, got both of them on sales from B&H in like new condition, hundreds of dollars off an already great starting price. I'm just waiting for a sale on the 24mm. The resolution of the glass easily handles 6K or 8K sensors so you get crisp details in the in focus areas. I use it with a speed booster on the Red Komodo which opens it up even wider than T2! Crazy sharp in the center and softer and somewhat vintage as you move to the corners, but sharpens up across the frame above T4. The macro capabilities are awesome and the icing on the cake that I feel really sets this lens apart from Mieke, DZOFilm, and other budget cine series of lenses. My only complaint is that there are only 3 lenses in this set. Really hoping Sirui will release an 18 or 20mm along with a 70 or 85mm.

[2.53 lb] Recently got these lenses and have used them for almost two months across various projects, from commercials in New York to a short film in Miami. Here's what stood out:

- Exceptional build quality.
- Impressive brightness with an aperture of 1.9, resulting in beautiful bokeh.
- Consistent weight across the lenses – a real game changer when working with gimbals.
- Comes with a good quality practical carrying case for five essential lenses.
- Top-notch optical performance: no focus breathing noticed, acceptable distortion.

For indie filmmakers, these are a top pick. Highly recommended.
