Snap Pictures in the Dark with Electrophysics AstroScope

US company Electrophysics has two adapters which can make your Canon or Nikon dSLR snap pictures in the dark. Such an application is not new and was previously implemented in surveillance and video cameras for recording footages in the dark. But the AstroScope 9350-series adapters are specially designed to be used with dSLRs.

Electrophysics AstroScope is an advanced night vision module that incorporates a state-of-the-art image intensifier that transforms dark scenes into bright, highresolution images. The AstroScope 9350EOS-P is specifically designed for Canon EOS-type cameras and mounts between the camera body and Canon EOS lenses using the standard Canon bayonet. AstroScope incorporates a high quality optic designed specifically for today’s digital SLR cameras and delivers full frame images with little or no vignetting.


These night vision systems fit between the camera body and the lens. There is a central intensifier unit (CIU) which illuminates the scene dramatically even if there is only a weak light source. What is special is that these adapters maintain the electrical connections required for image stabilizer operation and autofocus by the optics.

Fujifilm introduces F200EXR with Super CCD EXR


I remember "inventing" this idea while talking to a friend a year ago:

Single sensor high Dynamic Range mode: which captures different exposures with two sets of sensor pixels, which, when combined, gives an excellent level of detail in highlights that would otherwise be lost.

Seems Fujifilm was ease-dropping:


Faced with a market driven by the demand for higher pixel counts, yet conscious that high concentrations of pixels on small sensors can produce diminishing quality returns, Fujifilm engineers had a radical rethink about sensor technology. Why not make a sensor that can flex its behaviour according to the scene to be photographed? Why not give full resolution when bright light allows, but use the pixels in a different way when the light is not ideal? The FinePix F200EXR offers 3 switchable modes in one sensor:

High Resolution mode, which deploys all twelve million pixels, and is designed to offer the finest detail of intricate subjects when light is full and even
High Sensitivity and Low Noise mode, which caps two adjacent pixels together to produce 6 million large photodiodes, which are big enough to absorb light in the darkest of conditions, to produce low-light shots of extraordinary quality with minimal noise and grain; and
Wide Dynamic Range mode, which captures different exposures with two sets of six million pixels, which, when combined, gives an excellent level of detail in highlights that would otherwise be lost.
