So far I have not put these through their paces yet. It’s also an expensive purchase for me so there may be some inherent bias based on the desire to justify my purchase. Keep these things in mind as I give you initial impressions.
These lenses are hefty. They have that quality build feel. They come with shims and tools that will be helpful to adjust the lens if you need to. Right now everything is lined up well but I might need to do some shimming as the lenses are currently calibrated to go beyond infinity and not stop at infinity. That is the only current flaw I have personally found.
Everything feels smooth and is running as you would expect out of a quality set of lenses. Flair/ or Light Bloom is present with these lenses so be conscious of where light is coming from. I couldn’t detect much if any focus breathing which is excellent. The case it comes with is quality and very helpful to protect the lenses.
I don’t think you can go wrong with these for the price that they are listed they are affordable cine lenses that do a great job. Minor gripes about small things I can fix aside. Better than Rokinons by far in my opinion, and they don’t come with the premium of other lenses that seem to be expensive only because its cine.
Take what I said with a grain of salt. I like my purchase and am happy with it. Your mileage may vary based on your needs for film and what you tolerate. I hope that this review is somewhat helpful to make a decision on what I consider to be a big purchase decision.
