FEATURED REVIEWS
Shock, Awe, and OMG
I’ve been waiting breathlessly for the arrival of my new Sony A7 III since I placed the initial order immediately after the announcement. I prepared myself emotionally for the fact that I may not see it until May but Mr. UPS knocked on my door yesterday afternoon and made April 12th Christmas Eve. I’m a long-time professional Canon shooter (5D Mk III, 7D Mk II, 6D Mk II, 85mm 1.4 L, 100mm L, 70-200 2.8 IS L, Sigma 150 – 600, Tamron 2.8 70 – 200, (2) 600 EX’s, etc., etc., etc.). This list d...

Surveyed the market 6 months, pulled the trigger....
I've been doing photography since I was a little kid, eons ago. Started with 35mm film, and then went through a dozen digitals. I'd notice my peers shooting with a FF had inordinately better images, even though their tech was 6-8 years older. APS-C, 2/3, crop sensors -- no matter what the say -- are not nearly as good. FFs are pricey. I studied the market for 6 months, opting to shift away from my beloved Canon becuase DXO and other data proved to me dyn range was weak. That shifted me to Ni...

4D FOCUS — AF performance evolves
AF performance is improved using the same AF advancements as in the α9 and applying it optimally. Once the α7 III captures such unpredictably moving subjects as dancers, boxers, and wild animals in action, it won’t easily let them go.
4D FOCUS: Stunning wide coverage
693. Remarkable number of phase-detection AF points
This camera features 693 phase-detection AF points* covering approx. 93% of image area, plus 425 densely positioned contrast-detection AF points** to improve focus.
*Increased from 117 phase-detection AF points of α7 II.
**Increased from 25 contrast-detection AF points of α7 II.
4D FOCUS: Fast AF speed
Up to two times* faster AF performance
Combining focal-plane phase-detection AF for excellent speed and tracking plus high-precision contrast-detection AF, Sony’s sophisticated Fast Hybrid AF can capture fast-moving subjects in razor-sharp images. This system advances performance to double AF speed*.
*Compared to the α7 II in dim light. Sony test conditions.
4D FOCUS: Steadfast tracking
Enhanced AF tracking for swiftly moving subjects
The AF performance inherited from the α9 accounts for AF tracking with enhanced precision for continuous shooting of quick action. With faster image sensor readout, even complex subject motion can be tracked and sudden movements can be predicted with great precision, letting you capture decisive moments.
Reliable AF down to EV-3* brightness
Advanced AF algorithms contribute to high AF precision down to light levels as low as EV-3*, for more reliable autofocus in dark scenes.
* ISO 100 equivalent, F2.0 lens, in the AF-S mode.
Focal-plane phase-detection AF supports A-mount lenses*
693-point focal-plane phase-detection AF not only covers a wide area and responds instantly—it offers the benefits of high tracking performance even with an A-mount lens mounted via mount adaptor LA-EA3.*
* With SSM or SAM lenses only. With the LA-EA3 mount adaptor. Focal-plane phase-detection AF not supported for movie recording. AF-C can only be used when the "Phase detection" AF system is selected, but focus is fixed at the first frame during continuous shooting in any mode other than "Continuous: Lo" (Hi+, Hi, Mid).
Eye AF revolutionizes portraiture
With the α7 III, Eye AF can now be used with AF-C mode, for fast, effective eye detection/tracking performance when shooting stills. The easy maintenance of optimum focus on moving subjects can totally transform your portraiture.
Even if face is partially hidden*
*Eye AF may not work as well as intended, depending on type of shooting scene and conditions.
