||Smooth Autofocus Motor
||Sony term for their silent in-lens motor technology
used in lower-cost lenses instead of the faster SSM motors.
||A memory card format that is widely used
in compact cameras and increasingly, in consumer camcorders and
DSLR cameras because of the large capacities and high transfer
||Secure Digital - High Capacity
||A memory card format that
is physically identical to Secure Digital. They are available in capacities
from 4 GB up to 32GB with higher transfer speeds than SD.
||Secure Digital -
||A memory card format that
is physically identical to Secure Digital and SDHC. They are available in capacities
from 64 GB up to a theoretical limit of 2TB with extremely high transfer speeds.
||The delay between pressing the shutter release and the actual recording
of the image.
||A camera where the viewfinder uses the primary lens that provides the
image to the film or digital sensor (digital SLR has been shortened to DSLR in
common usage). The image is reflected to the viewfinder by a
mirror that swings out of the light path during the actual
exposure and swings back afterwards (hence, "reflex"). Usually
refers to a camera that offers interchangeable lenses but a few
models were made that used an optical SLR
design with a fixed zoom lens.
||Super-sonic Drive Motor
||Pentax term for their in-lens motor technology
||Hoya designation for filters with advanced anti-reflection coatings
||Tamron term for their high-performance series of lenses
||A metering mode that measures only a small central area of the frame
(usually indicated by a circle in the viewfinder). This is a useful mode
when the subject is illuminated very differently than the rest of the
scene or when you need the subject to be exposed as correctly as
possible, but the rest of the scene can be sacrificed. It is also used
when you want to expose the subject as a silhouette by spot-metering on
the bright background and recomposing before shooting.
||Super Sonic Motor
||Sony term for their in-lens motor technology
||Sony term for their image-stabilization technology
||Add-on lenses that mount to the front of a lens or between the camera
body and the lens and magnify the image from the lens as it passes
through to the image plane.
||Tagged Image File Format
||TIFF was originally a 2-bit black and white format developed for early
scanners and fax machines. Over the years it has evolved into a
full-color standard widely used by document management programs and fax
servers since the format allows the storing of multiple document pages
and images in a single file.
||Through The Lens
||Refers to automated metering systems that sample the light passing
through the lens to determine the correct exposure, even when a flash is
used. Older cameras used a hand-held meter or one mounted on the front
of the camera measure the correct exposure after which the camera was
set manually. Early automatic flash units required the camera to be set
manually and used a meter on the flash to control exposure.
||Canon term for their in-lens motor technology (high-performance)
||Tamron term for their lens-based image-stabilization technology
||Nikon term for their lens-based image-stabilization technology
||Zeiss for A-mount
||Zeiss lenses made for the Minolta/Sony A-mount. Available as top-end
lenses for Minolta and Sony DSLRs
(and some film SLRs).
Notably the only Zeiss lenses that autofocus.
||Zeiss for F-mount
||Zeiss lenses made for the Nikon F-mount. These manual-focus only lenses
are ultra-high quality and are generally considered to be some of the
||Zeiss for K-mount
||Zeiss lenses made for the Pentax K-mount. These manual-focus only lenses
are the same ultra-high quality as the other mounts.
||Zeiss for Ikon
||Zeiss lenses made for the Zeiss Ikon rangefinder camera.
||Zeiss for M-42 Screw-mount
||Zeiss lenses made
for older M-42 screw-mount cameras. These manual-focus only
lenses are not only used for older film cameras, but can be
fitted with adapters to work on many newer cameras, notably the
||Zeiss for Hasselblad
||Zeiss lenses made for the Hasselblad medium-format cameras. These
manual-focus only lenses are used where critical sharpness is needed for
the larger film format and now, larger digital sensors.
