Sony A9 vs Sony A99 II

 Image quality

Sony A9 employs 24 millions of effective pixels, whereas Sony A99 II uses 42 millions of effective pixels, so we are getting higher resolution of images from Sony A99 II. But now, you can see that both the two cameras are based on Full frame sensor of equal sizes and we know the sharpness and clarity of the images are mostly depend on the kind of sensor used by a camera. Also Sony A9 incorporates stacked CMOS sensor for super-fast readout and it also adds front end LSI hardware, ensuring that even in lowlight you are capable to capture sharp images. But again, back-illuminated full-frame 42.4MP Exmor R CMOS sensor that also features a gapless-on-chip design significantly maximizes the light gathering ability of Sony A99 II and produces a bit extra sharper and clear images compared to Sony A9. At the end, Sony A9 sensor is new as well as it has 75% larger pixels compared to A99 II. 35.30µm2 vs 20.43µm2, hence we expect better lowlight performance.

AF system

The AF system of Sony A9 is very intelligent and proactive as well. Sony’s every high-end cameras make the market more chaotic and aggressive because they always offer their users a wider AF points and every time they break their own records. The same thing they do with Sony A9 also. Creative 693 AF points – which is much more than any other camera currently exists in the market and if we say honestly then Sony unveiled this camera to give a tough fight to the high-end DSLRs and other mirrorless and compact cameras in the market.

Though both the two cameras come with hybrid AF system but Sony A9 cleanly wins the challenge by offering you 693 AF points that covers 93% of frame with 60 AF/AE tracking calculations per second. On the other hand, Sony A99 yields 79-point dedicated phase detection AF sensor with 399 focal plane phase detection AF points to produce a 79 hybrid cross AF point. In addition, Sony A99 II comes with Translucent Mirror Technology, with no moving mirror, ensures steady, continuous AF operation and live image preview during both still image and video shooting.


While shooting in the challenging light condition your camera needs high sensitivity range to capture subjects without using any flash. Here Sony A9 offers you top class of ISO range (204800) so that you can effectively capture your desire target with very minimal noise. Plus the camera has LSI hardware and stacked CMOS sensor that dramatically captures sharp images even in lowlight. On the other hand, Sony A99 II offers you one step lesser ISO range (102400) that may not be as effective as of Sony A9.

Shutter speed

Sony A9 offers you use maximum shutter of 1/32000 sec that stunningly freezes the fast moving subjects, plus one great advantage of Sony A9’s faster shutter speed is that it blocks the way of distortion as a result sharp and crystal clear images are surely possible, even makes lowlight shooting more interesting. On the other hand, Sony A99 II uses maximum faster shutter speed of 1/8000 secs only.

Continuous shooting speed

The Sony A9 offers the impressive capability including high-speed, blackout-free continuous shooting at up to 20fps, 60 AF/AE tracking for up to 362 JPEG or 241 RAW images. On the other hand, Sony A99 II enables continuous shooting at impressive speeds of up to 12fpswith AF/AE tracking.


Sony A9 lets you take 650 shots at a time, whereas Sony A99 II allows you take 490 shots only at a single time charge.


The vastly superior Sony A9 has got all the  specifications that a professional level photographers have prayed for. 693 AF points, 20 fps continuous shooting with no blackout, faster shutter speed etc. However, the price of Sony A9 is comparatively higher than that of Sony A99 II, but will be worth purchasing it.
