You're crystal clear, with no aberration of thought, detail, or delivery. A++ 🔝 I've learned a lot that I need to know, quickly and enjoyably. Much appreciated. Eagerly subscribed. 🏁
In Practice Transverse/Lateral aberration is typical at short focal lengths (wide lenses), Axial/Longitudinal aberration is typical at long focal lengths (Telephoto lenses). Crown glass is similar to the typical silicon glass we use for drinking water. The flint is a lead crystal like that of premium bottles and glasses and it is heavy.
Wow, very interesting! I'm looking at these 20,000 plus lenses for cinema, like ARRI and Zeiss, etc. Is that more apparent in video? Thanks :-) have a great day
I've done astrophotography with the 16-35 f4 L lens you have. Zooming in to 21mm focal length (IIRC) helps cut out the worst of the lenses weak outsides but coma is still present, looking worse with brighter stars. Shooting wider FL with this lens isnt really worth extra FOV as the quality will result in it getting cropped out anyway. There is also still vignetting at this focal length @f4 with a full frame but using flat frames can correct it. I made a very unplanned but decentish picture of the Milky way featuring the southern cross and Gum 12 nebula with the lens earlier this year. Im happy with the lens

I am studying Microscopy as part of my Medical Laboratory Science program. Your videos are helping me a lot! Thank you!!!! :)
Great information, clear and concise. Did not feel like a 16 minute video at all! Thanks
Very clear explanation. Thank you.
Excellent video 📸

You're welcome!
Now its more clear the science behind art.
Super stuff, thank you.
Wooow thank you great vedio
I have this problem with certain glasses I wear but I don't mind. It's interesting
What's it like being as smart as you? 😉
