ISO L (sic 50)

[gferdinandsen]

Back in the film days I frequently shot ISO 25 or 64 Kodachrome for waterfalls, it avoided having to use a ND filter. Those days are gone (RIP Kodachrome).


So here is my question, if read conflicting accounts: How does ISO L (sic 50) impact IQ? As an FYI, I'm using a 5D Mk2. Any thought are appreciated.


Thanks

As I understand it, you'll lose dynamic range since ISO50 is a pull from ISO100. That means highlights will be less recoverable.

Not really my area but it's what I've heard.
