The sensor is notable not only for its resolution but also optical format: 1/1,33 inch. Although the size of the pixels compared to 64-megapixel sensor has not changed and is still 0.8 microns. It is reported that this sensor captures much more light in low light conditions, than other sensors of a smaller size.

ISOCELL Bright HMX allows you to take photos resolution 12032 x 9024 pixels and also record video with resolution of 6K (6016 x 3384) with a frequency of 30/s. Supported by proprietary technology of combining pixels Tetracell for even greater capture of light (in this case, the image resolution is reduced to 27 MP) and Smart-ISO, the meaning of which directly reflects the title.

Some time ago, Ricoh has confirmed that this fall will release a new camera. It’s a little weird, as I was able to time the release to date and thus provide additional interest to the new product. The fact that on the 27th of November marks the 100th anniversary of the marches Pentax is now Ricoh.

The source, before carrying out such a test of the camera Sony a7R III, reviewed the work of the camera Sony a7R IV terms of use of this device for astrophotometry. He came to the conclusion that the Sony a7R IV also is “eating the stars”. The reason would be the algorithm of noise reduction at high shutter speeds, which does not distinguish the stars from the noise.

The tests showed that the algorithm is activated when the shutter speed is equal to or exceeds the 3.2 s. This is clearly seen on charts: the first corresponds to a short exposure, which is long.

The horizontal axis is spatial frequency, related to the sampling frequency of the camera and on the vertical axis — the values of noise. In the absence of noise reduction graph tends to a horizontal line. Treatment is especially pronounced in the blue channel (the final chart). Presumably, this is due to the use of part of the pixels for phase focusing.

The source said that in the Sony a7R III noise reduction began to manifest itself upon exposure of 4 seconds.
