Broadcast camera lenses at the Olympics can cost as much as a Lamborghini
- mark_element 9y agoA note, why do they use such small sensors (11mm) rather than the large sensors in full-frame DSLRs (42 mm)? Didn't quite get that constraint as being absolutely necessary.
- wmf 9y agoMostly for legacy compatibility, but the lenses would need to be even larger to cover a larger sensor.
- mozumder 9y agoSmaller sensors mean bigger depth-of-field. Shallow depth-of-field is incredibly distracting for video and difficult to work with. Everything is out of focus. It's mostly a photography/art thing to isolate your subject. You can see how sports program would want everything to be in focus, instead of just one player. That would look ridiculous.
- alfanick 9y agothis + Smaller sensor means larger effective focal length, which tends to smaller/cheaper lenses. 86x zoom for 35mm sensor would be much larger (so big that it would be impractical), heavier and much pricier than $200k.
- melling 9y agoJapan is already recording the Olympics in 8k. https://www.broadbandtvnews.com/2017/10/18/nhk-to-launch-8k-channel-in-december-2018/ https://www.broadbandtvnews.com/2017/10/18/nhk-to-launch-8k-... Does it use the same lenses?
- baddox 9y agoHow is that working? Is it just their commentary footage? I would assume that the competition footage is all licensed from the same official source.

- jazoom 9y agoInteresting read. Thanks. I almost didn't click due to the ridiculous title, but it doesn't do justice to the article.
