Sony F65 camera operational characteristics, power requirements, and field deployment concerns

15 years old. Gear and prices may have changed since.

DisputedParticipants disagreed and reached no conclusion. Read the findings as positions, not as an answer.

What the thread found

  • The F65 camera body draws 62 watts, the SR-R4 recorder draws 37 watts, and the complete system with viewfinder consumes 105-109 watts, making high-capacity battery systems essential for field work.
  • The camera outputs two 1920x1080 4:2:2 HD-SDI monitoring feeds plus HD-Y output for Genlock and shutter locking signals for 3D and motion control.
  • Power inputs use a standard 8-pin Lemo connector compatible with F35 power cables, providing 12V or 24V supply with outputs capable of delivering 4 amps at each voltage via Fisher connectors.
  • Preston MDR cables designed for the F35 are compatible with the F65 due to retained connector types, allowing reuse of existing lens control infrastructure.
  • If the SR-R4 recorder loses power during recording, it enters a data salvage mode upon restart that can take anywhere from seconds to 60 minutes with no on-screen time indication and no cancel option once initiated.
  • Pulling power from the recorder during data salvage mode risks putting the card into an undocumented limbo state where data recovery may become impossible.
  • The F65 records in 24P format rather than PsF, which may cause compatibility issues with some HD monitoring equipment.
  • Camera body weight is 11 pounds 7 ounces, the SR-R4 recorder weighs 3 pounds 15 ounces, for a combined system weight of 15 pounds 6 ounces.
  • The camera has left-side weight bias requiring offset mounting on the right side of bridge plates to maintain balance.
  • Center of gravity with typical cinema lens, matte box, and support equipment sits near the sensor plane.
  • No remote start/stop capability was available at initial deployment, though Sony style lens connectors were retained for future Preston integration to control shutter angle and frame rate.
  • The electronic menu system was refined to be simpler than previous Sony cinema cameras with a system information display similar to Alexa layout.
  • Early shipping included a non-HD eyepiece with plans for an HD eyepiece introduction in 2012, though no confirmed release date was provided.
  • Recorded output is in 709 color space with no down-converted NTSC output available for analog monitor compatibility.
  • Power consumption during standby operation with Preston control motor engagement reaches approximately 11 amps, exceeding typical single battery capacity.

Depends on

  • Information based on early 2011 pre-release seminar and initial field testing reports.
  • Field power consumption measurements were taken with specific ancillary equipment attached including UltraBrite2 monitor, MDR2, and two DM-2 focus wheels, making direct comparison to base specifications difficult.
  • Uncertainty remains about whether SR-R4 recorder improvements changed data salvage behavior from earlier SR-R1 experiences.
  • Voltage warning and failsafe system operation was not definitively confirmed on test equipment.
  • Reports involve subjective assessments of camera balance and mounting compatibility with specific existing support structures.
  • No image flip capability status was left unresolved in discussion.
