Kingpins, you're right. New developments bound to see all kinds of innovation in the future with cameras & photography.
But, back to my ex-favourite 20mm lens..... loved the way it got a wide angle but without the fisheye effect. Also gave great detail in the foreground and was light and unobtrusive.
I scanned the photos below from positive film slides. They're over 20 years old. The first is a simple scan with zero correction. I gave the second some tweaking to enhance the colour. They're both from East Java, volcanic Tengger region.
