The Canon CN-E 30-105mm joins the rest of the CN-E lenses that are engineered to serve the high-performance demands of the production community. I've shot with CN-E lenses and zooms a few times and they offer sharp, consistent and accurate quality. So you can confidently shoot with CN-E primes and zooms with no worry of color shift.
These are designed to work with 4K-resolution cameras making them future-proof. When used with a C100 or C300 for example, you can enable the recording of zoom and other settings along with video data, making shooting easier in any situation.
