What does status light 5d mean
The letter D was/is Canon's
designator for "Digital" and they started using that designator in the
late 1990s. For many years, Canon also manufactured 35mm film SLRs and
for over a decade from 1998 through 2008, they manufactured both 35mm
film SLRs and digital SLRs. The D was means as a designator that set
the digital cameras
apart from the 35mm film SLR cameras. The same applies to Nikon who
instead chose to simply replace their F and N designators for the 35mm
SLRs with the letter D for digital SLRs.
As for the numbers, those denote specific models. Within the Canon
system, cameras with three or four digit model numbers followed by the
letter D (i.e. 1000D or 550D) are entry-level, consumer-grade products
with plastic bodies, using SD cards for storage with burst rates of 4
frames per second or less. The most basic of these cameras is known as
the Rebel XS in the US but, called the EOS 1000D in most of the rest of
the world (The Japanese domestic market calls it the Kiss F). The most
recent model in this line is the Rebel T2i or EOS 550D. These models
cost between $450 and $900.
The next step up in cost, complexity and performance are the high-end
consumer or "prosumer" grade cameras that feature magnesium allow
bodies, faster burst rates exceeding 4 frames per second, and better
weather seals. These cameras have in the past, been designated with two
digit model numbers followed by the letter D (i.e. 20D, 30D, etc). The
most recent model in the line is known as the EOS 50D throughout the
world. The 50D is nearing discontinuation or replacement so its price
has fallen but, these models usually cost around $1200
Canon's premium (not necessarily professional) cameras have, sense the
advent of the EOS line, traditionally had single digit model numbers.
These included the EOS 5 and EOS 3 35mm SLRs and today includes the EOS
5D Mark II and EOS 7D models. These cameras build on the XXD series
with better build quality, the lack of scene modes on the mode dials,
and since the 7D, better autofocus and weather seals. They are not
quite up to the standards of the full-blown professional bodies but,
they are very close and often used by professionals as backup cameras or
the primary cameras of those on tight budgets. Prices for these models
range from $1600 for the 7D to $2500 for the 5D Mark II.
Finally, there are the "professional" models. These camera's are the
only cameras that get a single digit "1" model number such as the 1D
Mark IV and 1Ds Mark III models. The "mark" number indicates the
generation or version of the camera...The 1D Mark IV is the forth
version of the 1D and the 1D Mark III is the third version of the 1Ds
but, we expect a 1Ds Mark IV some time this year. Today's 1D and 1Ds
are Canon's fastest and best built cameras. They don't have any special
scene modes but, they can be heavily customized to fit the needs of the
individual photographer. These are also the most expensive cameras
Canon makes with prices starting around $5000.
