" Capture the most demanding scenes in one shot and retain details in highlights and shadows with the IQ250 thanks to its abundant 14 f-stop dynamic range." It throws me a bit as there are only ten zones in the zone system I am quite used to and Ansel and Fred where making contact prints from 8x10 negs at the time.. And now 5 zones in which there are detail which I've grown used to over many decades. They gave it seven. So 14 sounds as bit phantasmagorical. When I look up "dynamic range" its from whitest white to blackest black.. Who this relates to your real textured thresholds is anybody's guess who is not familiar with the materials first hand. If it was me id just say "don't worry about the latitude, Charley". "We've got you covered".
