The Full Frame Sensor That Delivers Cinema Quality

The heart of the Sony Alpha FX3 is its 10.2 megapixel full frame back illuminated Exmor R CMOS sensor. This sensor was specifically designed for video production. Sony optimized it for dynamic range and low light performance rather than still photography resolution.

The sensor delivers over 15 stops of dynamic range. This means you can capture detail in both shadows and highlights. Bright windows and dark interiors appear balanced in the same shot. Color grading becomes easier because you have more information to work with.

Low light performance is truly impressive. The FX3 produces clean footage at ISO 12800 and beyond. I have shot in candlelit rooms and achieved usable results. The dual native ISO feature helps maintain image quality at higher sensitivity levels.

The sensor pairs with Sony’s BIONZ XR processor. This combination delivers fast autofocus and smooth 4K recording. The processor handles the heavy lifting so you can focus on your creative work.

Video Recording Capabilities That Impress

The Sony FX3 offers recording options that satisfy most professional needs. 4K recording at 120fps opens up creative possibilities for slow motion content. You can capture action sequences and dramatic reveals with ease.

At 24fps, the camera records 4K with full pixel readout. There is no line skipping or pixel binning. This results in sharp and detailed footage. The full frame look with shallow depth of field becomes readily achievable.

Recording formats include XAVC S and XAVC HS. Bit rates reach up to 600 Mbps for high quality masters. The camera also supports 10 bit 4:2:2 internal recording. This provides enough color information for professional color grading.

For maximum quality, the FX3 outputs 16 bit RAW video over HDMI. Connect an external recorder like the Atomos Ninja V. You get ProRes RAW files ready for high end post production.

The camera records continuously without time limits. The active cooling system prevents overheating. You can document entire events without stopping.

Autofocus System That Never Misses

Sony’s autofocus technology shines in the FX3. The camera features 759 phase detection points covering 92% of the image sensor. Fast moving subjects stay sharp and in focus.

Real Time Eye AF tracks human and animal eyes with remarkable accuracy. The camera locks onto eyes and follows them through the frame. Interviews and documentary work become stress free. You can concentrate on composition while the camera handles focus.

The autofocus system works in light levels as low as EV negative 6. Dark venues and nighttime shoots pose no problems. The camera finds focus quickly even in challenging conditions.

Touch focus on the rear LCD provides intuitive control. Tap the screen to shift focus between subjects. AF Transition Speed and AF Subject Shift Sensitivity let you customize focus behavior. Create smooth rack focus effects or maintain sharp focus on your primary subject.
