The SLR Magic APO HyperPrime 50mm T2.1 Cine Lens is one of a new collection of fast primes aimed at professional cinematographers. When taking pictures with many image-dominant, open light sources, it is common for correction defects to show up. However, because the SLR Magic APO-HyperPrime CINE 50mm T2.1 is an apochromatic (APO) lens, longitudinal chromatic aberrations are corrected by its unique optical design and selection of optical elements. The color defects are therefore significantly lower than the defined limits. Bright / dark transitions in the image and especially highlights, are rendered with no colorful artifacts. Thanks to the low level of longitudinal chromatic aberration, there are no visible aberrations. So an illuminated portrait scene by night with many light sources in front of and behind the actual focal plane appears close to reality, without displaying complementary, color contrast edges. Its high performance with an open aperture also makes this lens a great choice for portraits or close-ups. Features a completely new optical and mechanical design, which has been developed to take into account the special and increasing demands of high-resolution cameras including those with 4K and 6K sensors. The APO HyperPrime CINE lens series comes standard in PL mount and can be easily adapted to numerous camera systems. Optional mount adapters are a PL-mFT adapter, PL-E adapter and (included in this version) aluminum EF mount conversion adapter. The lenses all feature a standard focus rotation angle of 300 degrees and uniform measurements. This combination makes the lenses ideally suited for professional cinematography.
