General Information:

For visual trailblazers

With extreme full-frame movie performance including high sensitivity (expanded ISO up to 409600), 15-stop wide dynamic range, 4K 120p

Large pixels deliver high sensitivity and low noise
The new full-frame 12.1-megapixel back-illuminated?Exmor RTM CMOS image sensor packs major innovations in light gathering, wiring and output optimisation. These deliver blazing doubled readout speeds, superb image quality throughout the whole sensitivity range, 15-stop wide dynamic range, and reduced rolling shutter, with the sensor also providing focal-plane phase-detection AF.

Up to 8x more powerful BIONZ XRTM image processor
Along with the new sensor and its unprecedented speed, the BIONZ XR image processing engine has also been newly developed and packs up to 8x more processing power. With a future-oriented architecture, it delivers high quality images faster for superlative still and video expression, as well as dramatically improved camera interface responsiveness.

Stunning AF performance even at 4K 120p
The new Exmor R full-frame image sensor and revolutionary BIONZ XR image processing engine deliver always-active pinpoint AF for astonishing detail in both space and time, and stunning 4K movies even at 120 frames per second or in slow motion. With the resolution and depth of field only possible from a full-frame sensor, the results are spectacular.

10-bit 4:2:2 recording
Record right on the camera with the amazing richness of 10-bit depth and 4:2:2 colour sampling, for far greater flexibility in image grading, post-processing and compositing.

All-Intra encoding available
As well as Long GOP, All-Intra encoding is now provided. This encodes every frame independently at bitrates up to 600Mbps, to capture complex motions more accurately for recording on either internal or external media, and allow more efficient editing workflows.

Superior quality and smaller files with XAVC HS
The new XAVC HS recording format uses HEVC/H.265 encoding to achieve twice the compression efficiency of AVC/H.264 encoding, for superior image quality and smaller file sizes .

Our renowned sensitivity delivers expanded ISO 409600
The renowned sensitivity of the series scales new heights, with an expanded ISO range for movies from 80 to a remarkable 409600 (standard range 80 - 102400). With advanced light-gathering and output optimisation, the 12.1-megapixel full-frame sensor achieves low noise throughout the sensitivity range, and can capture usable images in near total darkness.

S-Log3 gamma, S-Gamut3.Cine gamut as on pro camcorders
The S-Log3 gamma curve and S-Gamut3.Cine colour gamut, shared with pro camcorders, provide wider dynamic range and easier colour matching for smoother post-production workflows.

HLG (Hybrid Log-Gamma)
HLG (Hybrid Log Gamma) simplifies HDR production, producing footage for HLG-compatible BRAVIA TVs on the camera with no complex post-production, and smooth gradations from the 10-bit colour depth.
[1] High flexibility to fine-tune images as desired (colour grading required)
[2] Instant high-quality image (colour grading not required)

Image quality improvements
The new BIONZ XR image processing engine delivers improvements in colour reproduction, stability against different light sources, natural tonal gradation and roll-off, and reduced rolling shutter.

    Why Sony? Unmatched Innovation and Quality

    1. Superior Visuals with Sony TVs

    Sony's commitment to excellence is perhaps most evident in their television technology. With models featuring 4K and 8K resolutions, OLED and LED displays, and HDR capabilities, Sony TVs offer unparalleled picture quality. Technologies like the Cognitive Processor XR enhance the viewing experience by mimicking the way humans see and hear, providing realistic and immersive visuals.

    3. Groundbreaking Gaming with PlayStation

    Sony's PlayStation consoles have revolutionized the gaming industry. The PlayStation 5, with its lightning-fast SSD, stunning graphics powered by ray tracing, and immersive haptic feedback, offers a gaming experience like no other. Exclusive titles and a robust online community further solidify its position as a must-have for gamers.

    4. Innovative Camera Technology

    Learn more about Digital Cameras

    Buying a digital camera can be overwhelming but important if you want your memories to last a lifetime! Here is a very quick guide to help with this decision.

    1. Determine what you need
      What type of photography will you be doing? (portraits, landscapes, macro, sports)
    2. Megapixels are good and bad!
      The more megapixels often equates to more noise in the picture. If you're only printing images at a normal size then anything over 5 megapixels will be fine. If you start blowing your images up you might want to pay the extra money for the upper end of what's on the market today.
    3. DSLR or Point and Shoot / Compact Camera?
      While Digital SLRs are getting more affordable they are not for everyone. They do however produce extremely professional photos! While a Compact point and shoot is great for a trip, many are even waterproof.
    4. Optical Zoom is King
      Not all "zooms" are created equal. Digital zooms simply enlarge the pixels which makes it look more pixelated. If you're looking for a zoom lens make sure it's an optical zoom (most modern cameras have them of at least 3x in length ie they'll make your subject three times as big with an increasing array of "super zooms" coming onto the market at up to 12x Optical Zoom).

    Started with FedEx gone wrong. Thought they lost the computer! Had to order a new one since work couldn't wait. 2nd MSI overnight delivery for a really fair price. Unexpectedly, both show up at my door at the exact same time by 2 FedEx trucks. Had them both up and running for work in 45 mins. Was so impressed kept both computers. Jordan at CompSource is what a customer service associate should be. He answered his phone every time I called. No delays in service and very knowledgeable. Found exactly what I needed on the spot. This would have taken weeks with any other company. Have had 8 laptops in my life and this company has been my favorite. Thanks Jordan! MSIFORLife
