HISTORY
During the last several years Canon has developed a series of lenses with
the Image Stabilizer (IS) function. Gyroscopic sensors mounted on the
x, y, and z axes within the lens housing detect and counteract lens shake
and camera vibrations by slightly moving an image stabilizing lens group
along the optical axis. IS became a hit almost instantly among Canon shooters.
Soon the old rule of never handholding a lens at any shutter speed below
the reciprocal of the lens focal length became obsolete.
IS
technology easily provides sharp images at light levels 2-3 stops less
than that necessary with pre-IS equipped lenses. Most of us have seen
fast acting nature photographers pick up and handhold a 500 or 600mm IS
lens and still make sharp images. Even with large glass mounted on tripods,
IS allows a higher percentage of sharp images in low light, at slow shutter
speeds, and at extreme focal lengths. Canon now produces IS lenses at
almost all focal lengths and has recently incorporated this technology
in the video camera and binocular product lines. Reviews of lenses with
the current Canon IS technology are almost universally positive with respect
to performance and the enhanced ability to make sharp images in the field.
A few photographers have voiced concerns regarding the additional cost
of this technology and that IS may slow autofocus performance in the Canon
system. However, overall IS has been a very successful achievement for
Canon and this feature alone is responsible for numerous Nikon to Canon
conversions in the nature photography community over the last several
years.

Nikon
coined the term Vibration Reduction (VR) for their own image stabilization
technology. Most Nikon shooters welcomed the announcement of a VR lens
joining the Nikon line-up in 2001. A year later when the first 80-400
VR lens finally made it to store shelves, Nikon shooters at last had the
chance to apply VR technology to their image making. The first generation
VR lens, however, had a number of shortcomings and mixed reviews quickly
began to surface. The biggest complaint was that the new VR lens incorporated
an older camera driven autofocus system rather than the faster and newer
silent wave (SWM) technology. Photographers were disappointed using this
lens, particularly on subjects in motion. Although my own experience proved
the VR system was effective and allowed handholding at slow shutter speeds,
the older autofocus technology was very frustrating when attempting to
use this lens on moving targets. I tested the lens extensively at the
La Jolla cliffs in California during the winter of 2002 and soon thereafter
sold my lens because of its autofocus limitations. Admittedly I have been
spoiled with the AF-S performance of my other lenses. Other shortcomings
in the first VR lens include a weak and quirky tripod collar system and
that the zoom was an external system which physically extended lens length.
These features probably could be tolerated, however, had Nikon merged
AF-S and VR in the 80-400mm product.
Nikon
combined AF-S and VR technology in the 70-200 f/2.8 AF-S VR lens in 2003.
This is a totally new product, not a makeover of previous lens designs,
and this time Nikon has produced a truly superb lens. The combination
of AF-S and VR with a new optical line-up in the lens allows photographers
to make extremely sharp images under even very marginal light conditions.
Nikon shooters in denial can stop grinding their teeth, silently thinking
they do not need VR or IS to make sharp images. I can testify that it
is a fact: VR (or IS) in combination with good technique will increase
the percentage of sharp images in the field.
THE LENS
Nikon’s 70-200mm AF-S VR lens is a completely new product, not a
revision of a previous 80-200mm lens. It is slightly longer (length 8.5
inches/215mm) and more narrow (diameter 3.4 inches/87mm) than the 80-200
AF-S. It weighs in at 3.2 lbs or 1.50 kg. The lens carries the new G designation,
indicating that there is no manual aperture adjustment ring at the lens
base where mounted to the camera. It had been speculated that the 80-400mm
lens did not incorporate AF-S technology due to a shortage of electronic
contacts and that the new G mount may free up electrical contacts for
combining AF-S and VR. Others suggest that the G mount is simply a cost
saving measure in the lens development. Since I nearly always adjust F
stops using the command dials on the camera body I do not miss having
the manual ring available. The lens contains more glass in more groups
(21 elements/15 groups) compared with the previous 80-200mm model (15
elements/11 groups). There is also roughly a 50% increase in ED (low dispersion
high quality) glass in the new lens.
Moving
out from the camera mount, four buttons are found on the left side of
the lens when held for horizontal shooting. The top button selects between
M/A and M mode for focus. M mode is for complete manual focus. M/A allows
for autofocus with manual touch up. The AF-S system will not override
a manual adjustment unless the shutter is released and then partially
depressed. The second button from the top controls the focus range of
the lens. Two options are available: “Full” and “2.5m
to infinity”. The minimum focusing distance (MFD) at 70mm is about
5 feet, slightly less in manual focus mode. The two lower buttons control
the VR options. The third button from the top turns the VR function on
or off. The lowest button allows the photographer to choose between normal
and active VR modes.
The
lens comes complete with a newly designed tripod collar which remains
permanently mounted on the lens barrel, a huge improvement over the 80-400
VR lens. There is a mounting foot for tripod use with a new quick release
system for removing the foot from the collar. I had my lens retrofitted
with a quick release plate that screws directly onto the tripod collar.
This circumvents any advantages of the quick release but I prefer to have
the foot off to the side for handholding. This arrangement is particularly
useful for mounting flash brackets.
The
lens features a two-ring design with the innermost ring controlling focal
length from 70 to 200 millimeters. The zoom is smooth and is internal
without rotation or extension of the lens. The outermost ring controls
focus. At the very end of the lens is a series of focus lock buttons,
typical of the other AF-S telephoto lenses.
The
lens hood is ample. It bayonet mounts forward for shooting and reverses
for travel and storage. The hood should be used at all times as the additional
glass in this lens will make it more prone to flare and ghosting, particularly
when shooting towards a light source. Even the lens cap was reworked and
features a center pinch release mechanism as compared with the older side
pinch mechanism. This allows easy on/off of the lens cap while the hood
is in the forward shooting position.
PERFORMANCE
I really enjoy using this lens. Since I frequently use much larger lenses
on tripods, it is liberating to be able to walk around with this lens,
to have the flexibility of handholding it and to still be able to make
sharp images in lower light conditions. Even with VR turned off there
is no question this lens is sharper then the 80-200 AF-S lens that I sold
soon after acquiring the 70-200 AF-S VR. All of the f/2.8 Nikon AF-S lenses
acquire autofocus at an astonishing speed and with a high degree of accuracy
and this lens is no exception in that regard. Coupled with the D1X sensor,
images with exacting detail are readily made.
Did
I mention the lens was sharp? Previous reviews had suggested Nikon’s
sharpest telephoto was also one of its most expensive, the 400mm f/2.8
AF-S lens. Recent independent tests indicate the new 70-200 AF-S VR lens
surpasses the 400mm’s gold standard. The lens is compatible with
the current TC1.4e (1.4x) and TC2.0e (2.0x) teleconverters. One published
review used resolution studies to show that the 70-200 AF-S VR zoom lens
in combination with the TC1.4e teleconverter was as sharp as the highly
acclaimed prime Nikon 300mm f/4 AF-S lens. Tell your friends that a zoom
lens mounted to a teleconverter will match a prime lens in sharpness and
see what kind of response you get!
The
VR system is very effective. Depressing the shutter button part way down
will activate the VR system. It takes approximately one second for the
system to turn on and settle. Using the AF button on the back of the camera
body (custom setting) to start AF does not start VR, an important point
to keep in mind if you frequently start AF independently of the shutter
button. My evaluation, and that of others, shows that the VR does not
interfere with AF-S performance. Most Canon shooters indicate that IS
does slow autofocus performance and this may be one edge in the Nikon
VR technology compared with Canon’s IS system. VR works with the
N65, N80, F5, F100, D100, D1 and D2 series camera bodies. VR should be
left on at all times except when completely locked down on a tripod, working
a static subject. The VR may introduce blur in this situation by “searching”
for motion not present. Use the normal mode (so VR will not fight pan
motion either in horizontal or vertical compositions) except when shooting
from a moving car or boat. When shooting from a moving vehicle it is best
to use the active mode and VR will attempt to remove motion in every axis.
The camera should be turned off before mounting or removing the lens.
Expect increased battery consumption with VR active.
USING THE LENS
I acquired my lens at the end of May 2003 and took it with me to Custer
State Park, South Dakota that month. The Wildlife Loop at the southern
end of the park provides wonderful opportunities to photograph wildlife
at close range. I have had the most productive experiences in this park
during the hour just before dawn when wildlife can be easily found in
wonderful wrap around predawn light. I almost always shoot from my vehicle
using it as a moving blind. I had my large glass on a window mount and
was able to handhold the 70-200 AF-S VR for close range work. The image
of the bison calf was made using this lens at ISO 400 f/5, 1/30 while
hand holding this lens.
Ever
since I started using this lens, I find myself continuously looking for
opportunities to use its zoom! In the summer of 2002, I traveled to Vince
Schutte Black Bear Sanctuary in northern Minnesota. I made very few images
on my first trip with my 80-200mm AF-S lens because of low light levels
and slow shutter speeds. This year I returned to the sanctuary in June
and took about half of the images during that trip hand holding the 70-200
AF-S VR lens. This allowed me to make intimate low perspective bear pictures
by quickly kneeling down, making the image and then moving away. I was
able to get into and out of positions rapidly, action not possible with
larger lenses mounted on a tripod.
In
St. Paul Alaska I fitted the lens with a Canon close-up diopter auxiliary
lens and was able to walk around making close-up or macro pictures, such
as this one of a beached jellyfish.
ISSUES
I have very few concerns or issues with this lens and would recommend
it without reservation. It is very exciting to see Nikon producing successful
combination AF-S and VR products. It seems like it has been a long time
in coming, even longer when you are standing next to your friends using
those white IS products. All professional camera gear is expensive and
the average street price for this lens at the time of writing is US $1,700.
The MFD could be better (five feet at 70mm), but this statement applies
to the entire line up of Nikon telephoto lenses, particularly relevant
since Nikon does not offer AF capable extension tubes. That being said,
I really enjoy having this lens in my camera bag and look forward to new
VR additions in the future.

Olivero's first significant nature photography experience occurred in
Africa in 1978. When time allowed, he made pictures of nature and other
subjects off and on for the following twenty years. The majority of his
images, however, were made in the last five years, during which time he
also has been actively involved in the nature photography community. To
