The Sony Fs5 has received a new free firmware 2.0 update. One of the key features is an auto Neutral Density filter function changes the strength of the electronically controlled variable N.D. filter. This is an excellent use of Sony’s amazing new electronic N.D. By adjusting the N.D. the user is allowed to adjust exposure without affecting aperture, shutter speed, or gain values. This translates to all elements of the image such as depth of field, motion blur, and noise, being unchanged while simultaneously adjusting exposure values of the image. Other additions include expanded zebra functions as well as GPS capability.
Ever since the camera was announced Sony has alluded to the coming capability of RAW recording. For those who wish to record RAW with the FS5 you must acquire the newly announced RAW upgrade option for 600 dollars, model number CBKZ-FS5RIF. This then allows, though the 3G-SDI connector, continuous output of DCI 4K 60p and up to 240p RAW in 1080p. If you have right recorder you can then record 12-bit RAW video or you can also choose to convert this to Apple ProRes for recording. This workflow has proved popular with FS7 users who pair the camera with the Convergent Design Odyssey 7Q+. Unlike the FS7 however, the FS5 has an extra trick. It can also record DCI 4K at up to 120 fps for up to 4 second bursts. It does this by using the internal cache recording function of the camera. The images are buffered in camera and then played out of the 3G-SDI port at a regular frame rate for recording, once image capture has finished. This system will be familiar to anyone who has the FS-Raw option on the FS700 which features the same ability. Both the free and the paid firmware updates will be available in June.
