How it's made - a $10,000 Canon Lens

[Basil]

The Canon 500mm f4 L lens is close to a $10,000 lens. https://www.usa.canon.com/cusa/consumer/products/cameras/ef_lens_lineup/ef_500mm_f_4l_is_ii_usm

Found a fascinating video on how this monster is made.

I had no idea how labor intensive the manufacturing process is on these lens's. Impressive!

Thanks Basil for showing us this. When I see a video like that, I think of the work involved in the Hubble telescope! Hard to imagine. PJ
