— Last month’s Photokina,
here, brought a preview of some forthcoming new
d-SLR lenses, camera and flash items from Sigma.
Underscoring its role as a camera maker as well
as a lens manufacturer, the company showed an
advanced d-SLR in its model SD1.
The camera is said to have a huge
46-megapixel resolution level using
a 1.5x crop Foveon X3 sensor.
Exact pricing and availability plans
were not revealed, however.
Similarly, the company did not
give marketing specifics on a new
150mm f/2.8 Macro lens with an
internal HSM AF motor. The lens
offers a 1:1 magnification ratio and
a nine-blade circular diaphragm.
It was joined by the new APO
120-300mm F2.8 EX DG OS
HSM lens, which is said to include
optical image stabilization
and other improvements over the previous 120-
300mm f/2.8 lens.
Also announced was a pair of hot shoe flashes,
in the EF-610 DG Super and EF-610 DG ST. Both
feature a guide number of 61, manual flash mode
and TTL auto flash exposure with most popular d-
The SD1 d-SLR features a 3-inch LCD and
11-point AF system.
The APS-C-sized X3 direct image sensor has
46-megapixel resolution (4,800 by 3,200 by 3 layers),
the company said.
All primary RGB colors are captured at each pixel
location. The three silicon-embedded photo-detector
layers are stacked vertically to take advantage
of the silicon’s ability to absorb red, green and blue
light at different respective depths, enabling more
accurate color reproduction without the generation
of moiré. Therefore, no low-pass filter is required,
enabling the capture of light and color with a more
3D feel, the company said.
Combined with the camera’s dual True II processing
engines, the SD1 is said to quickly process
high-resolution images while allowing a
smooth graduation of color, the company said.
The company’s new flagship
camera is designed with
a lightweight, solid magnesium
alloy body and weather-resistant
The camera uses Type 1
Compact Flash cards, and is
compatible with UDMA, enabling
fast processing of large
amounts of data.
Other features include an
11-point twin cross sensor and
3-inch 460,000-dot TFT color
Sigma said the camera will
be compatible with more than
40 Sigma lenses.
In addition to the internal HSM AF motor, the new
150mm f/2.8 Macro lens includes Sigma’s integrated
Optical Stabilizer function. The lens is said to be
weather-resistant and includes a floating focusing
system that moves two different lens groups in the
The Hyper Sonic Motor (HSM) is said to be quiet
and fast while also allowing full-time manual focus
The new APO 120-300mm F2.8 EX DG OS HSM
lens adds optical image stabilization and optical improvements
over the previous version.
It includes a weather-resistant design and an
HSM for quiet, high speed AF.
Meanwhile, the EF-610 DG ST flash offers manual
power control down to 1/16 power, while the EF-610
DG Super covers an 8-stop range down to 1/128 in
