  • E-P5 base ISO and Low ISO compared

    After doing a low ISO exposure bracket with the E-P5 for Ulfric on our Olympus UK site the other day, here are two shots (both RAW+JPEG) taken at ISO 200 (base ISO) and Low ISO (100). The Zip download link is here:

    I'd be very interested to know what everyone here thinks of these two results.

    By the way, centre-weighted metering was used, @f/1.8, 75mm m.Zuiko, tripod was used and IS was switched off.

    It seems to me that if we are happy to expect diminishing image quality when ISO sensitivity rises, why shouldn't we be content for this to happen as ISO reduces below base ISO? In which case, we should be offered the option of several ISO steps below base ISO in our cameras.

    E-P5 base ISO and Low ISO compared

    I don't see any difference... Low ISO seems equal to 200
    Low ISO and 1/8000 give us the possibility to work with fast apertures during daylight, and that's a great thing.
    I agree with you we should have a low ISO extension as we usually have with high.

      Re: E-P5 base ISO and Low ISO compared

      A base ISO of 25 would allow a low ISO of 12. Now that would be nice.
      It's the image that's important, not the tools used to make it.
