The Sony a7R IVA continues the noteworthy series of highly capable full-frame cameras, characterized by impressive stills and video performance and versatility. This fourth edition of the a7R sees the inclusion of an updated 61MP sensor along with faster processing, improved AF performance, and a more well-rounded feature-set for both high-end photo and video applications. The sensor's structure promotes impressive image quality and a copper wiring layer dramatically improves data transmission speed for creating 14-bit, high-resolution 61MP stills with a native sensitivity range from ISO 100-32000, which can be further expanded to ISO 50-102400. The quick processing also helps to reduce rolling shutter and other motion distortions for the clean rendering of moving subjects. This unique compositing mode allows you to achieve even greater resolution than the 61MP sensor affords. Working in conjunction with the sensor-shift image stabilization, this mode shifts the sensor while making 16 consecutive exposures in order to acquire approximately 240.8MP of information for greater color accuracy and detail than possible with a single exposure, along with an impressive image size of 19,008 x 12,672-pixels. This focusing system also achieves especially quick speed and reliable tracking, as well as enhanced low-light focusing response down to -3 EV.
Expand Flexible Spot employs neighboring focus points to retain focus on moving subjects even if the originally selected point loses focus. The Focus Magnifier function can be used for critical focus when homing in on minute subject details. Oversampled 4K recording is also possible, which uses a 6K capture area with a Super 35 crop for greater detail. This full pixel readout is void of pixel binning for higher quality imagery with reduced moiré and aliasing. In addition to high-resolution internal recording, uncompressed HDMI output also enables the use of an optional external recorder for clean 4K recording with 4:2:2 sampling.
A dedicated High-quality setting enables a 120 fps refresh rate for especially smooth playback of moving subjects. Extensive weather sealing, including enhanced sealing around the battery cover, terminal cover, and chassis joints, has been employed to resist dust and moisture for reliable operation in harsh weather conditions. Both 3.5mm headphone and external microphone ports facilitate greater control over audio recording.
