Sony BURANO Camera Review

Disclaimer: Sony lent the camera for review purposes; no compensation or sponsorship involved. Not a professional filmmaker.

Initial Excitement

• Combination of features:
  • IBIS (In-Body Image Stabilization)
  • Autofocus
  • Built-in variable ND filter
  • Compatibility with PL lenses and Sony E-mount lenses
• Unique and novel features
• Potential future advancements

Disappointments

• Expectations vs. reality:
  • High hopes for Venice-like performance
• Realization: Purpose-built machines outperform multi-functional ones
• BURANO is a jack of all trades but master of none

Test Results

Rolling Shutter

• 8.6k full readout: 18.8 milliseconds
  • High for a $25,000 cinema camera
• FFc mode 6K: 17.6 milliseconds
  • Slight improvement but softer image
• Super35 5.8K: 12.6 milliseconds
• Super35c mode (2x punch in): 8.5 milliseconds
• Comparison to Alpha 1: 4K pixel-binned mode at 7.9 milliseconds
• No 4K pixel-binned mode on BURANO

Dynamic Range

• Imatest results
  • 8K raw: 14.4 stops total, 10.9 clean stops
  • 8K raw with noise reduction: 11.8 clean stops
  • H.265 mode: 12 clean stops with no NR, 12.6 with NR
  • 8K H.265 on 4K timeline: 12.5 stops, 12.9 with NR
  • 6K full-frame C mode on 6K timeline: 12.8 stops
  • 5.8K Super35: 11.5 stops
• Comparison to Alpha 1
  • Similar dynamic range and performance

Features and Performance

• Autofocus and IBIS perform well but not best-in-class
• Limitations with IBIS and autofocus functionality in certain modes
• Reliability
  • Built like a tank, has a fan
  • Media differences (expensive CFexpress Type B cards vs. SSD)

Additional Features & Testing

• HDMI output issues: settings not retained when modes are changed
• Implementation of mirrorless camera functions
  • Distortion compensation, peripheral illumination, focus breathing compensation, active stabilization modes
• IR pollution issue with built-in ND filters

Value Proposition

• Similar performance basics to Alpha 1 but at a much higher cost
• Specific needs (e.g., Genlock) are where BURANO stands out
• Mirrorless cameras can be rigged to compensate for some missing features

Final Thoughts

• BURANO serves as a proof-of-concept with potential for future innovation
• May not be worth the investment for the average user
• Perfect for specific professional uses
