INTRODUCTION
I
first heard about the Lensbaby about a year ago. I was casually
surfing photo-related sites on the Internet. Strange, I thought—an
accessory that deliberately causes images to be out of focus!
With all talk these days about high-speed autofocus lenses with
the most refined optics and technology, the Lensbaby represents
a technological leap—backwards! And that, my friends, was
refreshing.
I
recently got a Lensbaby 2.0 in the Nikon mount and I decided to
see for myself what it was, how it worked, and what it could do.
Lensbaby’s concept is a simple one. It is a manually operated
tilt-shift lens with very limited depth of field that produces
selective-focus images. When I say the lensbaby is manually operated,
I mean it; it has no electrical metering, no aperture ring, no
focus ring-- nothing. What it does have, however, is a clever
design that enables the user to push, pull, and bend the lens
body itself to create interesting images.
SIZE AND DESIGN
The
Lensbaby 2.0 is a very compact unit. Its diameter is about the
same as your camera’s F-mount, and the body is less than
2” long. There is a single element lens which is optically
coated and produced from low-dispersion glass, with a focal length
of 50mm. The lens body itself is constructed from a flexible but
rigid piece of tubing. I like to think of this lens as an elephant’s
trunk; the “Snuffleupagus” of lenses! The Lensbaby
has no aperture ring or metering contacts. This feature (or lack
thereof) means that you will need to use manual metering unless
you have a camera that supports AI lenses, like the Nikon D2X.
With a D2X, you can set the maximum aperture of the lens in the
camera menu and use Aperture-priority metering. With other SLR’s
you will need to rely on an educated exposure guess, a handheld
meter or your histogram.
You
can, however, change the aperture of the Lensbaby. Via a clever,
low-tech design, the Lensbaby comes with a set of magnetic donut-shaped
inserts that can be placed over the lens itself. Magnets in the
lens body prevent the aperture ring from touching the lens surface.
The Lensbaby 2.0 comes with rings that allow the user to choose
from f/2.0 (no ring), f/2.8, f/4.0, f/5.6, and f/8. The smaller
the aperture, the greater the depth of field and larger the “sweet-spot”
of focus.
BASIC USE AND HANDLING TECHNIQUE
Within
seconds of using the Lensbaby, all the old rules of optics suddenly
started coming back to me. Need to focus closer? Pull the lens
away from the body. Push the lens towards the camera body and
it focuses further out. No longer could I rely on my camera’s
autofocus system, although the focus-indicators in the viewfinder
still operated normally. Mastering focus with the Lensbaby definitely
takes some getting used to. It is a two-handed process that is
made easier by a large “finger ring” on the lens.
I would suggest that when starting out with a Lensbaby that you
use a tripod. A tripod will keep the camera-to-subject distance
constant, support your camera, and allow you to get familiar with
the “push-pull” operation of focusing the lens. Another
good trick when first using the Lensbaby is to start at f/5.6.
The increased depth of field and smaller “sweet spot”
of focus as compared to f/2.0 or f/2.8 will really help with focusing
as you learn to use this tool.
Once
I had gotten used to focusing with the Lensbaby, I started to
shift the “sweet-spot” around in the frame of my D2x.
By bending the Lensbaby, you can move the area of sharpest focus
to your intended subject. Depending on the aperture ring installed,
the sweet spot ranges from tiny (f/2.0), to most of the frame
(f/8.0). By taking advantage of the selective-focus abilities
of this lens, it is possible to produce effects that would be
impossible with a standard SLR lens.
PERFORMANCE
Lensbaby
2.0 gives exactly the kind of performance that one would
expect with a one-element lens. Focus can be challenging
to achieve, depending on the subject. Don’t expect
to use the Lensbaby to get razor-sharp images of fast moving
subjects. Chromatic aberrations are apparent in the out
of focus areas. In any other lens review, this kind of performance
would be totally unacceptable, but these distortions are
exactly the reason why people find the Lensbaby
so refreshing to use! Changing apertures in the field is
a fairly simple task. Each Lensbaby includes an accessory
kit with a small storage case and a tool for removing the
aperture donuts. |

The
front and rear surfaces of the Lensbaby optic are easily accessible
for cleaning, and the lens itself is supplied with a soft pouch
for storage.
As
I stated earlier, you will need to use manual metering unless
you have a body that supports TTL metering with AI lenses. I had
no trouble at all getting great exposures with my D2x in Aperture-priority
mode. I also was able to use the SB-800 speedlight in iTTL mode
with no issues whatsoever.
The
Lensbaby is at its strongest when you have a clearly defined subject,
but want to add an impressionistic effect to the rest of the frame.
Portrait photographers, wedding photographers and landscape photographers
will find a wealth of possibilities to explore with this lens.
If you shoot action, you will be faced with a challenge to get
in-focus shots.
ACCESSORIES
The
Lensbaby 2.0 has a 37mm front filter thread, which allows
it to accept a range of screw-in accessories, including
wide angle and telephoto adapters, and close-up filters.
Lensbabies manufactures a set of close-up attachments (+4
and+10 diopters) that enable you to easily focus on objects
12” away. Stacking the diopters permits focus down
to 2”. I would definitely recommend a tripod when
using the Lensbaby for macro work. At first, I thought that
using a selective-focus lens for macro shots would be counterproductive.
At close working distances, the plane of focus is very small
to begin with. |

However,
the tilt-shift feature of the Lensbaby gives a completely different
level of control over the focus plane, which results in unique
images. |
