Woodpeckers and magpies, for example, not to mention the bright whites of egrets combined with foliage and shadows of their habitat. If I were to buy a DSLR body I'd hate to have spent multiple thousands of dollars on a tool that restricts me to a limited dynamic range. Wildlife doesn't hold still long enough to bracket exposures and combine in Photoshop. With the R8 and film back, and with the Leicaflexes, changing my capture medium's dynamic range is a sub-$10 expenditure.
