Metabones Speed Booster
Speed Booster ULTRA for E-Mount
and X-mount cameras
Sharper corners, less distortion,
reduced vignetting
New optical design: advanced
5-element/4-group optical design incorporating ultra-high index tanatalum-based
optical glass to achieve extraordinary optical performance with improved corner
sharpness, distortion and reduced vignetting.
Like the revolutionary original
Metabones Speed Booster announced in January 2013, the Speed Booster ULTRA
has a magnification of 0.71x, and so it effectively reduces the crop factor of
mirrorless cameras with DX-sized sensors, such as Sony E-mount and Fuji X-mount
cameras, from 1.5x to 1.07x. However, the new ULTRA design makes very
effective use of exotic materials at the furthest limit of glassmaking
technology, and as a result is well corrected for use with virtually all
fullframe SLR lenses regardless of exit pupil distance. Thus, the Speed Booster
ULTRA performs extremely well with professional-grade f/2.8 zoom lenses such as
the 24-70mm f/2.8 and 70-200mm f/2.8 zooms by Canon and Nikon to produce
17-50mm f/2.0 and 50-142mm f/2.0 high-speed zooms, respectively.
Similarly, high-speed fixed focal length lenses such as a 50mm f/1.2 will be
transformed into a 35.5mm f/0.9 lens with excellent contrast and resolution
from the center all the way to the edges of the image. (More information can be
found in the press release here)

Note:
1.
Requires lenses
supporting distance information.
2.
Autofocus disabled for
Contax N and Contax 645 lenses.
3.
A third party zoom
lens may need to be registered with the Smart Adapter first
in order to detect its maximum aperture. Autofocus is disabled for most
third-party lenses.
4.
This Speed Booster
ULTRA is designed to cover an APS-C image circle which is not big enough
to cover a full-size 36mm x 24mm sensor.
5.
Sony NEX cameras
cannot display aperture values beyond f/1.0. If a f/1.2 Canon EF lens is used
with Speed Booster ULTRA the resulting aperture is f/0.9 but the camera
body displays the original aperture f/1.2 to the camera body. i.e, lenses
slower than f/1.4 report boosted aperture to camera body; lenses at or faster
than f/1.4 report original aperture to camera body. (with firmware later than
V0.38)
6.
Some improperly-made
M42 screw mount adapters may short the electronic contacts of the Speed Booster
ULTRA and cause damage to the Speed Booster ULTRA and/or camera body.
7.
Many manual focus
lenses (e.g. OM 28/2.8, OM 50/1.8, Leica R 15/3.5) have rear protrusions
(spikes, levers, other appendages) which would damage the optics and/or housing
of Speed Booster ULTRA They need to be modified before they can be safely
used on Speed Booster Check and make sure there are no rear protrusions from
the adapter/lens combination before using on Speed Booster. Scratches and
damages caused by rear protrusions on Speed Booster are not covered by
warranty.
8.
Some telephoto lenses
such as the Leica-R Telyt 560/5.6 may have significant vignetting in the corners.
9.
This Speed Booster
ULTRA is NOT fully compatible with full-frame Sony A7, A7R and A7S. When
Speed Booster® ULTRA is used with Sony A7, A7R and A7S, the camera will
turn on the "APS-C Size Capture" mode automatically.
Autofocus
Autofocus is supported, with the
following known limitations.
·
Autofocus speed is very slow and inadequate for most moving subjects. The
autofocus speed is unfit for professional use for sure, and it would disappoint
most enthusiasts.
·
Only Canon-branded lenses introduced in or after 2006 are officially
supported. Autofocus is disabled for older Canon lenses and most third-party
lenses, including most Sigma, Tamron and Tokina lenses and all Contax N lenses
modified by Conurus.
·
On FS series (e.g. FS7, FS700, FS100), autofocus may be available only in
photo mode but not in movie capture mode.
·
Continuous AF is not supported.
·
DMF mode (direct manual focus) is not supported.
·
For non-camcorder camera bodies (e.g. NEX-7), during movie capture, if the
subject moves to a different distance, half-press the shutter release button to
re-activate autofocus and lock onto the subject again. Since autofocus speed is
slow, there may be visible disruption in the resulting footage.
·
The first two autofocus attempts are used to calibrate the lens and as a
result may not lock successfully on the target. Half-press the shutter release
button again and autofocus will lock successfully.
·
Autofocus may have difficultly locking onto subjects which are very close
to the nearest focusing distance of the lens.
·
Autofocus accuracy depends heavily on the working condition of the lens.
Lenses with hidden problems which may not be apparent on Canon DSLRs will lead
to inaccurate and unreliable autofocus on Sony NEX. Typical problems of this
kind that we have seen include an unsmooth/erratic autofocus mechanism (e.g.
getting stuck intermittently at a certain focusing distance), a worn-out gear
train with out-of-spec backlash, a faulty/worn-out distance encoder or other
faulty/worn-out internal sensors.

List of manual focus lenses which REQUIRE MODIFICATION to be used on Speed
Booster ULTRA
Many manual focus lenses have rear
protrusions (spikes, levers, other appendages) which would damage the optics
and/or housing of Speed Booster ULTRA. They need to be modified before
they can be safely used on Speed Booster ULTRA. Check and make sure there
are no rear protrusions from the adapter/lens combination before using on Speed
Booster ULTRA. Scratches and damages caused by rear protrusions or by poor
quality adapters are not covered by warranty. The following is an incomplete

Why Metabones®?
Since its inception, Metabones has been
designing and manufacturing lens adapters recognized among professionals and
enthusiasts as leaders in design and workmanship.
Contrary to the popular trend of other
factories using an aluminum ring painted black on the camera-body-side, we
instead take no short-cut but use precision-machined brass with chromium
plating on both the camera-body and the lens sides of our adapters, in order to
ensure smooth mounting, great appearance, and durability. The lens side of the
adapter features a strong leaf-spring structure, strengthening the adapter-lens
connection and ensuring tightness of the lens in order to reduce wear and
prevent focus errors and optical alignment issues from appearing.
Metabones uses matte-black treatment to
keep internal reflection to a minimum in order to maintain the maximum optical
quality possible with the lens.
All Metabones Adapters follow this
tradition of uncompromising precision, robust build quality and outstanding
finish. Our new Smart AdapterTM series of products add
industry-leading electronic interfacing technology from Canada, with true
electronic control of the lens' aperture directly from the camera body.
Features
·
Both camera-side and lens-side of the adapter are made of brass, precision-machined
and plated with chromium.
·
Satin surface finish - just like your OEM lens and camera mounts.
·
Precise fit and solid connection - lens has no play, gap or wiggling when
mounted on adapter and no adjustments are required to fit your lens.
·
Designed to reach infinity focus while maintaining the correct registration
distance required to maintain optical quality of CRC lenses or lenses with
floating elements.
Our Smart AdapterTM series
adapters have the following additional features
·
True electronic integration of aperture diaphragm - let camera
automatically choose aperture in P or S exposure modes, or dial in yourself on
the camera body in A or M modes.
·
EXIF data such as lens identification, focal length and aperture.
