With the a9, Sony has delivered faster continuous shooting
speeds than flagship DSLRs in the same compact, full-frame mirrorless body that distinguished the a7 series.
This 24-megapixel camera boasts 693 phase-detect and
25 contrast-detect AF points covering 93 percent of the
sensor. Burst speeds hit a blistering 20 fps with AF tracking
engaged. It has a native ISO of 100 to 51,200 (expandable
from 50 to 204,800), 4K video recording, two SD card
slots and a refashioned battery that delivers an excellent
(for a mirrorless camera) 480 shots per charge.
BUYER’S GUIDE 2017
The wait for the GH4’s successor is over. The GH5 predictably ups the
ante with high-quality 4K recording—you can save a 10-bit 422 file at
30p to an SD card or shoot 4K at up to 60p. Full HD frame rates top off
at 180 fps. Autofocusing is driven by Panasonic’s Depth from Defocus
technology, which has had its speed doubled from previous iterations. It
has a dust and weatherproof design with a sturdy magnesium-alloy build.
Canon EOS M5
The M5 boasts a 24-megapixel, APS-C-sized CMOS image
sensor with Canon’s Dual Pixel AF autofocusing system.
You’ll enjoy high-speed shooting speeds of up to 7 fps with
continuous autofocusing and full HD/60p video recording.
The camera offers a built-in EVF and a 3.2-inch tilting display.
There’s Wi-Fi for image transfer and remote
control, plus Bluetooth for quicker pairing
with mobile devices.
The successor to the X-T10 features a new APS-C-sized, 24-megapixel
X-Trans CMOS III sensor and X-Processor Pro image-processing engine.
The new sensor/processor duo combine to push the camera’s ISO
settings up to 12,800 and deliver faster autofocusing. The X-T20 has 91
AF points (up from 49 in the previous model). Phase-detect AF pixels
cover approximately 40 percent of the imaging area. The X-T20 can burst
at up to 8 fps for up to 63 JPEGs using a mechanical shutter. Switch to the
electronic shutter and you can hit a continuous shooting rate of 14 fps.
The X-T20 can record at 3840 x 2160 video at 30p for up to 10 minutes at
a clip. It can also record full HD at up to 60p in one of the camera’s nine
film simulation modes.
