In
our last issue, in my article on
three telephoto lenses, I wrote
that “as sensor resolution increases,
the lenses you use will be required to
do more work to capture and resolve
all those tiny, subtle details.” Since
that issue published, Sony announced
another pro-level full-frame mirror-
less camera, the Sony a7R IV, which
packs in 61 megapixels on its CMOS
image sensor. That’s more resolution
than you’ll find on some medium-for-
mat cameras.But new pro cameras aren’t just
increasing megapixel counts. For
example, other features on the a7R
IV include Real-time Eye AF, which
“employs artificial intelligence to
detect and process eye location data
in real-time, locking and maintain-
ing focus on the subject’s eye with
extreme precision. This is available for
both animal and human subjects.” It
even works when obstacles temporar-
ily block the subject from your cam-
era. As long as your finger is pressedhalfway down on the shutter button,
the camera will resume tracking once
the subject appears in the frame again.
But again, as a photographer, you
need to know that your lenses are work-
ing overtime to not only resolve details
for static subjects but also for those that
are moving quickly, erratically, coming
toward you or moving in and out of the
frame. Lenses must instantaneously,
reliably communicate and respond
with the camera bodies. And vice versa.

The Nikon NIKKOR Z 14-30mm f/4 S
ultra-wide zoom lens (for its full-frame
mirrorless camera system) provided
very good image quality throughout the
zoom range, from 14mm to 30mm. In
this photograph, shot at the 30mm end
of the zoom at ƒ/4.0, the lens produced
wonderful bokeh and blur behind the
yellow rose in the foreground.A^ First^ L
