Flagship full frame mirrorless camera Sony A9 was a long time ago — she will soon be 2.5 years, which is why many enthusiasts are eagerly waiting for the successor. According to rumors, it will announce in October, and then will show at the PhotoPlus event in new York, which will be held 24-26 October. Apparently, all this will happen: once the source has published the first live pictures of Sony α9II, so the camera is already in or is, or is about to fall on the conveyor.

The source managed to obtain three photos Sony α9II, but published only one. Judging by the picture, the new flagship of Sony will be almost a copy of the previously announced models A7R IV.

According to the source, Sony decided to concentrate on internal instead of external changes. So, α9II needs to obtain the most advanced image sensor, the resolution of which, presumably, will be 36 MP.

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.

However, no release of a commemorative products will not do. Though fans of the brand “new” is unlikely to please. According to the source, Ricoh will celebrate the 100th anniversary of Pentax release plugs into the hot Shoe O-HC171 with appropriate engraving.

Camera Sony a7R IV also is “eating the stars”

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.

Камера Sony a7R IV тоже «ест звезды»

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.
