This Sony Burano technical guide analyzes three technological revolutions in professional cinematography: the 5-axis IBIS system (first cinema camera with PL mount to include it), which compensates up to 5.5 stops of handheld vibration; the hybrid autofocus with AI that integrates 627 phase-detection points and intelligent facial recognition, breaking the historical taboo of AF in cinema; and the Cine EI mode, professional workflow that locks the camera to base ISO (800/3200) while previewing different exposures through monitoring LUTs. Includes step-by-step configuration, PL vs E-mount modes, when to enable or disable each system, and practical production examples. Complete guide to master the technical capabilities of the Sony Burano on cinema productions.

Until recently, no professional cinema camera with a PL mount had included in-body stabilisation. Why?
Technical reasons:
Sensor size: Full Frame sensors are large and heavy, making them difficult to move quickly
PL flange distance: The PL mount has a 52mm flange distance, leaving very little room for IBIS mechanisms
Lens weight: PL cinema lenses weigh several kilograms, creating inertia that complicates stabilisation
Required precision: In cinema, stabilisation must be perfect or not used at all. There is no middle ground.
The Sony Burano has overcome all these technical obstacles. The IBIS system compensates for movement across 5 axes:
Pitch (up/down tilt)
Yaw (left/right pan)
Roll (rotation around the optical axis)
X-axis (horizontal shift)
Y-axis (vertical shift)
The camera adjusts the behaviour of IBIS depending on the mount in use, optimising stabilisation for each lens system. This is one of the key strengths of professional Sony cameras:
For tripod, dolly, or when using a gimbal
Handheld without a gimbal: Obviously. That is precisely what it is designed for.
Telephoto lenses: Lenses of 100mm or more amplify any vibration. IBIS is essential.
Subtle camera movements: Small framing adjustments, smooth subject tracking.
Run & gun: When you do not have time for a tripod and need stability immediately.
Moving vehicles: Filming from cars, boats, etc. (though a gimbal would be preferable for very abrupt movements).
Tripod or dolly: IBIS can introduce micro-movements when the camera is static. Always OFF on a tripod.
Gimbal: IBIS and the gimbal can 'fight' each other, causing erratic movements. Exception: single-handed gimbals with very abrupt motion, where IBIS on Low may help.
Very fast camera movements: Whip pans, crash zooms. IBIS cannot keep pace and may cause warping (image distortion).
Lenses with optical stabilisation (OSS) enabled: There may be a conflict between both systems. Test both options and use whichever performs best.
Long static shots: For maximum sharpness on fixed frames, set IBIS to OFF.

View Sony Burano →This technical manual explores the hybrid autofocus system with artificial intelligence — an innovation that is rewriting the rules of focusing in professional cinematography.
Historically, autofocus has been a taboo in professional cinematography. Focus pullers are artists who control focus manually, creating smooth transitions and directing the viewer's attention with precision.
Why was autofocus considered problematic?
"Hunting": The AF constantly searched for focus, causing pumping (focus drifting back and forth)
Incorrect decisions: The AF focused on the wrong element (background instead of subject)
Abrupt transitions: Robotic focus changes that looked anything but cinematic
Lack of creative control: The AF made decisions — not the cinematographer
What has changed?
On-sensor phase detection technology combined with AI subject recognition has revolutionised autofocus. The Burano features:
627 phase-detection points covering almost the entire sensor
AI-powered facial and eye recognition (it genuinely understands what a face is)
Configurable transition speed (you can make focus pulls smooth and truly cinematic)
Touch tracking (you select the subject, the AF locks on and follows it)
"Hybrid" means it combines two technologies:
Phase detection: Fast and precise, measures the distance to the subject directly
Contrast detection: Fine refinement that guarantees perfect sharpness
"Fast" means it is quick enough for video use, with no perceptible lag whatsoever.
The AF continuously adjusts focus to keep the subject sharp, even as it moves through the frame.
Ideal for:
Key setting: Subject Change Sensitivity
Example: You are filming an interview. The subject moves slightly forwards and backwards. With AF-C on medium sensitivity, focus adjusts smoothly to keep them sharp throughout.
The AF focuses once when you press the button, then locks and holds.
Ideal for:
Full manual control — but with intelligent assistance tools:

More information →This complete guide teaches you how to master Cine EI mode — the professional workflow used by directors of photography on high-end cinematic productions worldwide.
Cine EI (Cinema Exposure Index) is a working mode that locks the camera to its base ISO (800 or 3200) and allows you to simulate different exposures via an offset that only affects the monitoring LUT, not the actual recording.
Film stock analogy:
Imagine you are shooting on film stock. The film has a fixed sensitivity (say, 500 ASA). You cannot 'change the ISO' once the film is loaded in the camera. Instead, you expose more or less depending on the scene, then adjust during development. Cine EI works the same way: you always record at base ISO (maximum quality), but you can 'preview' how it will look with different exposures using the LUT.
Maximum image quality: You always record at base ISO, where the sensor delivers its best performance
Consistent workflow: ISO never changes between takes, making matching in post-production far simpler
On-set flexibility: You can adjust the look without touching the recorded image
Smart metadata: The Burano records the EI offset and LUT used directly in the clip's metadata. Software such as Catalyst Browse applies these settings automatically.
You have two options:
How to decide?
General rule: if you need to open the aperture beyond T2.8 to expose correctly, you should most likely be at ISO 3200.
Practical example:
You are filming an interview indoors with natural window light. You meter the scene and need T2 to expose correctly at ISO 800. Rather than shooting at T2 (shallow depth of field, difficult to keep in focus), you switch to ISO 3200. Now you can shoot at T4, with greater depth of field and improved sharpness throughout.
The MLUT is essential in Cine EI. Without it, you will see raw S-Log3 (flat and desaturated). With the MLUT active, you see how the image will look after grading.
LUTs included in the Burano:
s709: Sony's standard LUT, similar to the look of Kodak 2383 film stock. Natural tones, soft contrast.
709(800): Standard Rec.709, more contrasty than s709. Well suited to broadcast.
Teal & Orange: Modern Hollywood look. Separates cool tones (backgrounds) from warm tones (skin). Hugely popular in advertising and contemporary drama.
Warm: Warm, amber tones. Perfect for romantic scenes, sunsets, and cosy atmospheres.
Cool: Cold, bluish tones. Ideal for night scenes, thrillers, and technological environments.
Vintage: Bleach bypass effect with faded sepia tones. Evokes the aesthetic of films from the 1970s and 80s.
How to activate the MLUT:
Important:
You can run different LUTs on each output simultaneously. For example: VF: s709 (for the operator) | SDI OUT: Custom show LUT (for the director/DIT) | HDMI OUT: No LUT (for an external recorder capturing raw S-Log3)
With the MLUT active, zebras and the waveform measure the LUT output, not raw S-Log3. This distinction is critical.
