Best Telephoto Zoom
Canon EF 70-200 f/2.8L IS II USM
The Canon EF 70-200 f/2.8L IS II USM
is massive lens but, with its aperture
range of f/2.8 to f/32, this monster
provides the highest quality zoom.
The beautiful bokeh (complimented
by a well-rounded, eight blade dia-
phragm), fast and accurate focus and
numerous measures against aber-
rations makes the Canon EF 70-200
f/2.8L IS II USM one of the most versa-
tile zoom lenses on the market.
The quality doesn’t come cheap,
however, and purchasing this lens
will set you back $1,800. A cheaper
and lighter version is available with a
maximum aperture of f/4 for $1,100.

Best Cine Lens Line
Zeiss CP.3
The follow-up to the highly regarded
CP.2, this line of cine lenses is one
of the highest quality available on
the market. Available in 15mm T2.9,
25mm T2.1, 35mm T2.1, 50mm T2.1
and 85mm T2.1, each lens in the line

features improved ergonomic design
compared to the line’s CP.2 prede-
cessors, 14 blade diaphragms and
improved protection against aberra-
tions and reflections. If you only want
the best for your set, the Zeiss CP.3’s
performance is unparalleled.
The full line is priced at $20,812
with the cost of individual lenses
ranging from $4,400 to $6,700.

Factors to consider
The lens is the most important part of
a camera so it’s no wonder so many
people agonize over new lens pur-
chases. A good lens is expensive and
specialized so, whether you’re buying
your first or your twentieth lens,
it’s important to know exactly what
you’re looking for and which lens best
fits your needs.
Here are the main factors you’ll
need to consider before investing in
your next lens.

Mount System
The mount type is the first thing you
need to consider with lenses. Every
camera manufacturer has a different
system for connecting lenses to their
cameras. This connection is known
as the mount. When you shop for a
new lens, you need to make sure the
one you choose will attach to your
camera. Some of the most common
mount systems for DSLR and mir-
rorless systems right now are: Canon
EF, Nikon F, Sony E mount, Fujinon X
mount and Micro Four Thirds (MFT),
used in most Panasonic cameras.
Some lens mounts pair exclusively
with cameras from the same manu-
facturer, but you’ll encounter cinema
cameras using the EF mount, for
instance, even outside of the Canon
ecosystem. There are also manu-

range covers the most commonly
used focal lengths and is generally
affordable with prices ranging from
a several hundred dollars to a couple
thousand depending on the mount
and manufacturer.

Effective Focal Length
When choosing a lens based on focal
length, you’ll also want to consider the
size of the sensor in the camera it will
be paired with. Sensors smaller than
full frame come with a crop factor that
will increase the effective focal length
of your lens by as much as two times
for MFT sensors.
That means a 35mm lens, when
paired with an MFT sensor, will have
a field of view equivalent to that of a
70mm lens. On a camera with a APS-C
sensor with a 1.5-time crop, the same
lens will have a field of view approxi-
mately equivalent to a 52mm lens.
Know the crop factor for your camera
to be sure you’re getting the lens you
need.

Prime vs. Zoom
Prime lenses have one fixed focal
length while zooms can be used to
cover a range. They can have a long or
a short throw, covering a wide range
of focal lengths or only a very narrow
range. Zoom lenses are typically more
expensive, especially as the zoom range
increases, but they can take the place of
several prime lenses and are convenient
for run-and-gun situations where you’re
reframing often. Zoom lenses come
in two varieties: internal zooming and
external zooming. External zooming
lenses are more common and more
affordable, but internal zooming lenses
are a better choice when accessories
such as matte boxes are a factor.

facturers such as Sigma, Tamron,
Rokinon and Fujinon that offer the
same lens across several different
mounts. Higher-end brands like Zeiss
and Cooke even offer interchangeable
lens mount options. When investing
in lenses, consider which cameras
and mounts you anticipate using in
the future so that you can continue to
use you collection of lenses after your
next upgrade.

Focal Length
Once you determine compatibility,
focal length will likely be the driving
force in your purchasing decisions as
you fill out your collection of lenses.
It is usually the first number denoted
in a lens description and is measured
in millimeters. The lower the number,
the wider the angle of view, allowing
more of the scene to be captured. A
lens with a longer focal length will
bring the viewer in closer to the action
and create more space compression in
the image.
Focal length is one of the main de-
terminants in the appearance of you
image and is a useful storytelling tool
when used deliberately.
Lenses at the extremes — super
wide or extreme telephoto — are
generally only used in specific circum-
stances or for a specific creative effect.
Very wide lenses will often distort the
image, which can be distracting in
the wrong context. Lenses with focal
lengths between 20mm and 100mm
are much more common in video
production, with 50mm lenses more
or less approximating the field of view
of the human eye.
You’ll also find that most manufac-
turers, including Canon, Nikon, Sony,
Sigma and Tokina, make very similar
24-70mm zoom lenses — this zoom

ONCE YOU DETERMINE COMPATIBILITY, FOCAL
LENGTH WILL LIKELY BE THE DRIVING FORCE IN YOUR
PURCHASING DECISIONS.

mately equivalent to a 52mm lens.

Prime vs. Zoom
Prime lenses have one fixed focal
length while zooms can be used to
cover a range. They can have a long or
a short throw, covering a wide range
of focal lengths or only a very narrow
range. Zoom lenses are typically more
expensive, especially as the zoom range
increases, but they can take the place of
several prime lenses and are convenient
for run-and-gun situations where you’re
reframing often. Zoom lenses come
in two varieties: internal zooming and
external zooming. External zooming
lenses are more common and more
affordable, but internal zooming lenses
are a better choice when accessories
such as matte boxes are a factor.

On the other hand, prime lenses
will often have a faster, or wider, max-
imum aperture than zooms. Fewer
elements in prime lenses also leads to
generally sharper images compared to
equivalent zoom lenses.

Aperture
The aperture is the opening in the
lens that allows light to enter the
camera. The size of this opening is
controlled by a multi-bladed iris,
which also influences the appearance
of bokeh — or blur— in your image.
More blades lead to a more circular
opening, producing smoother, more
pleasing bokeh in the defocused areas
of the image.
This size of the aperture is a key
measurement and is noted with the
maximum width to which it can open.
You’ll usually see this measured as the
F-stop of a lens, for instance f/2.8, f/4
or f/5.6. The smaller the F-stop num-
ber, the more open the aperture can
become, allowing in more light.
Also, the wider the opening of the
aperture, the shallower your depth of
field will be. This means the plane of
focus in your image will be thinner.
Think of a shot where the subject is
in focus and the background is very
blurry — it was probably done with
a wide open aperture, like f/2.8 or
wider.
When shopping for a new lens,
look for maximum apertures of f/4 or
wider. Zoom lenses will often fea-
ture a variable maximum aperture
depending on the focal length used.
This means you’ll likely need to adjust
your exposure when zooming. Zoom
lenses with a constant aperture are
easier to work with, but they typically
come at a higher cost.

Likewise, lenses with wider maxi-
mum apertures will usually be more
expensive. However, moving from
f/4 to f/2.8 can make a big differ-
ence for videographers working in
low light situations or who want the
cinematic look shallow depth of field
can provide.

Sensor Size
Another important factor of your lens
purchase is the sensor format of your
camera. The main types of sensors to
consider here, from largest to smallest,
are full frame, Crop Sensor (APS-C and
Super35) and Micro Four Thirds. MFT
is both a sensor size and a mount type.
Since full frame sensors are the
largest, lenses made to cover a full
frame will provide an image large

LENSES WITH WIDER MAXIMUM APERTURES ARE
USUALLY MORE EXPENSIVE, BUT MOVING FROM F/4
TO F/2.8 CAN MAKE A BIG DIFFERENCE FOR VIDEOG-
RAPHERS WORKING IN LOW LIGHT.
