That was a wholly terrible explanation of the difference between T-stops and F-stops!!!…..You really should not put out instructional videos UNTIL you understand what you are explaining. F-Stop is a calculation of the amount of light the aperture lets in at a specific focal length. It does not take into account the amount of glass in front of the aperture. SO the amount of light reaching the sensor at F2.8 between various lenses will vary. This doesn’t matter for stills images but is a pain when shooting film as the exposure will change when you change lenses for a scene or setup. So “Cine” lenses (as in “Cinema” abbreviated and not “seen” as you pronounced it) take into account in the calculations of light the amount of glass in front of the aperture as well soooo T2.8 on one lens will match exactly in exposure to ANY other T2.8 cinema lens…..That’s the whole point!
Firstly, thanks for explaining it in detail and apologies for breezing through it. Wasn't trying to be instructional about anything. But thank you for your feedback and will apply into future videos. Would love to do a deep dive in a separate video with further research. Hope you can go easy with the comments next time. There's no point being harsh on people trying to share their point of view. I'm ultimately learning as I go.
Yeap. They're very sharp. Quite similar to Sigma lenses. But Sigma Art lenses has better bokeh in my opinion but they're AF isn't as good compared to this.
What makes this a cine lens? Just the focus ring? From what I heard the optics is exactly the same as their photographic lens. How is the focus breathing?
According to Samyang, the glass elements are almost similar from its bigger cine lenses. And my guess it's categorised as one due to the video priority features that it comes with. Its still a better option than Sony's native prime lenses in my opinion.

Hello brother

Hey man! Yes the autofocus is great. Does perform like a native lens.
Thanks for watching!
Thanks for the video I have a question how can we update these lenses I need the adapter to update firmware?
Yeap! theres a lens station for firmware updates. Here's the link

Are the lenses sharp enough?
