 Photron APX
Superb light sensitivity allowing good depth
of focus even at high shutter speeds. Sensitivity of
the camera sensor has been estimated by independent
sources to be in the region of 400ASA allowing for F4/F5.6
@ 1000fps in daylight conditions.
True 25Hz playback 'video out' capability immediately
after capture. Also the video out can be connected to
a viewfinder for a zero-delay live feed allowing for
framing, focusing and panning during recordings.
High resolution at high frame rates: e.g. 2000fps at 1024 x 1024, 4000fps at 1024 x 512
Remote head allowing for greater access.
Interchangeable camera heads (10-bit mono and 30-bit color available). Mono head can be used in very low light conditions and with infra-red lights.
C mount or Nikon lens type fitting.
Start, centre, end or custom trigger mode settings.
Memory partition capability allowing for several captures before download. The camera has the extended 8GB memory (see datasheet). This will allow for several recordings before having to download to computer. This is a very useful feature esp. when filming unpredictable events.
Full system can be run off 12V battery power.

 Photron SA-1
Released in 2007, the Fastcam SA1 provides
blistering fast speed with unmatched light sensitivity.
Capable of over 5,000 full frames per second (fps) at
mega pixel (1K x 1K) resolution, the brand new CMOS
sensor provides true twelve bit pixel depth and is capable
of 150,000 fps at reduced resolution.
Building on the experience gained with the EMMY award
winning Ultima APX, the Fastcam SA1 is Photron's most
light sensitive camera yet, as well as providing the
greatest colour fidelity of any high speed camera available,
thanks to true 12-bit performance.
 The
Fastcam SA1 provides the perfect tool for those looking
for mega pixel resolution at true high speeds, as well
as those demanding sensitivity and performance with
an SDI digital output for TV/movie and commercial work.
Main Differences of the SA-1 over the APX.
The sensitivity is higher (at least 1-2 stops).
The image quality is better (dynamic range is higher and fixed pattern noise is lower).
Colour is much improved (new colour processing algorithms used).
The frame rate is higher (5400fps @ 1024x1024 compared to 2000fps for the APX).
Memory is the same as APX - 8GB.
Variable resolution function (can record @ 9000fps at 1024x576 which equates to 16:9).
The download speed over Gigabit Ethernet is faster (about 2x the speed of FireWire).
All-in-one unit is probably more practical for transporting and set up in remote locations.
Full system can be run off 24V battery power. |
systems for hire - the APX and the new SA-1. The APX provided
the stunning images as seen on Planet Earth and the new SA-1
is the choice of two new major forthcoming BBC wildlife productions,
LIFE and Nature's Great Events. The SA-1 has been used this
year for several major television commercials.
