Press Release - 21 July 2010
Sony expands A-Mount lens line-up for DSLR cameras
with three new lenses
Sony is expanding its already strong line-up of over 30 A-mount lenses with
new models that will appeal to seasoned photographers and those new to DSLR
cameras alike
The Distagon T* 24mm F2 SSM (SAL24F20Z)
The Distagon T* 24mm F2 SSM (SAL24F20Z) functions as a wide-angle 24mm lens
on full-frame cameras with 35mm sensors, or as a 36mm equivalent lens ideal
for general use on cameras with APS-C sensors. Jointly developed with Carl
Zeiss, it features the highly-regarded Carl Zeiss Distagon retro-focus lens
configuration designed for wide-angle lenses.
This lens is distinguished by its fast response focus and extremely quiet,
very smooth operation thanks to its built-in SSM (Super Sonic wave Motor).
It offers a wide and therefore highly versatile focal range from 0.19m to
infinity, and features a nine-blade circular aperture that along with the
large F2 maximum aperture contributes to smooth, natural bokeh effects.
In keeping with traditional Carl Zeiss design, the all-metal lens barrel has
been finished to a very high standard resulting in a visibly high-quality
appearance.
The DT 35mm F1.8 SAM (SAL35F18)
Part of the ‘Easy Choice’ series, offering photographers at all levels great
value, compact and lightweight lenses, the DT 35mm F1.8 SAM (SAL35F18)
weighs just 170g. It can be added to a lens kit system and carried without
noticeably increasing the weight of the bag.
With an approximately 50mm (35mm equivalent) focal length on an APS-C
sensor, this lens is ideal for snapshots and portraits under a wide range of
shooting conditions. The high-speed F1.8 maximum aperture is particularly
advantageous for hand held shooting in low light.
At just 0.23 metres, the DT 35mm F1.8 SAM (SAL35F18) has the shortest
minimum focus in its class, making it an excellent choice for dramatic
close-ups too. Whatever the shot, the internal Smooth Autofocus Motor (SAM)
drives the focussing group directly and ensures responsive and fluid
autofocus operation.
The 85mm F2.8 SAM (SAL85F28)
This is the first full-frame lens in the ‘Easy Choice’ range, so its launch
represents an important development of the line-up as a whole. The 85mm
focal length is a standard for portraiture because of the natural
perspective that it provides. On an APS-C sensor camera the 85mm F2.8 SAM
(SAL85F28) functions as a 127.5mm (35mm equivalent) telephoto lens – and
features a Sonnar-type optical design that is considered ideal for mid-range
telephoto lenses.
The lens is sharp center to corner, and features smooth defocusing thanks to
its large F2.8 maximum aperture and circular aperture design. At 0.6 metres,
the minimum focusing distance is the shortest in its class, and SAM motor
technology ensures smooth autofocus operation.
The quality optical and mechanical features of the lens mean it is suitable
for serious photography and should more than satisfy intermediate to
advanced users.
