Yes. DPReview is a well-known resource that provides downloadable RAW sample files for many of the cameras it reviews. Checking RAW samples is a good way to compare sensor performance and file flexibility without the extra processing applied to JPEGs. Keep in mind that RAW files still reflect factors like lens choice, exposure, lighting, and the RAW converter you use, so they’re best used alongside full reviews rather than as the only basis for a buying decision.
