GY-HD251

Studio production 

with HD SDI and 26-pin control

By combining the GY-HD251 
with the KA-HD250 adapter, 
you can create a studio system 
with camera control and 
tally/intercom bi-directional 
communication via 26-pin 
multi-core cable. For 
video/audio transmission, the 
HD/SD SDI signal allows long-
distance digital transmission at 
1.5 Gbps with minimal 
degradation via a separate 
coaxial cable.

Live HD recording

with tape and hard disk

With 720/50p acquisition 
capability, you can record 
smooth, full-frame high-quality 
images. Also, with genlock 
input and time code 
input/output, multi-camera 
shooting is possible. When the 
GY-HD251 is combined with 
the DR-HD100, hybrid (HDD 
and tape) high-quality ENG with 
extended recording times is 
possible.

HD cinematography

with 24 fps and film lenses

In addition to the 24 fps of 720p/24 
mode there are two extra gamma 
settings to choose from, cinema and 
film out, which gives the captured 
images a very film-like appearance, 
according to whether final distribution 
is on video or on film.  With the 
different film lens mount adapters 
available, prime film lens can be 
used, so creating an affordable digital 
cinematography system. To 
accommodate certain film lens 
adapters, the menu allows image 
inversion.
