Hello everyone! I tested Canon R8 recently. Photos and table are here: https://disk.yandex.ru/d/G6x03lBDWSO6ww When taking a test shot with the body lid on (or lens lid on) at 1/3 sec and ISO 100 a dim blue pixel cluster with coordinates X 1632-1636, Y 2951-2953 and two pixels of very dim red (almost gray) color with coordinates X 2019, Y 1774 and X 2019, Y 1774 are visible. As the ISO increases, these pixel clusters and pixels become visible with a shorter shutter speed. Other pixel clusters and pixels may also be visible. For example, at a shutter speed of 1/200 sec and ISO 1600, there are two dim blue pixel clusters with coordinates X 1626-1630, Y 2951-2953 and X 2547-2548 Y2550-2551, one dim red cluster with coordinates X 2017-2018, Y 1774 and one dim gray pixel with coordinates X 3859, Y 2082. As the ISO and/or shutter speed increases, the number and brightness of visible pixels and pixel clusters increases (the size of visible pixel clusters may also increase). For example, with a shutter speed of 1sec and ISO 1600 or 1/30 sec shutter speed and ISO 6400, two blue pixel clusters with coordinates X 1626-1630, Y 2951-2953 and X 2547-2548, Y 2550-2551 are visible, one red cluster with coordinates X 2017-2018, Y 1774, two blue pixels with coordinates X 3728, Y 3353 and X 5621, Y 3240 and one red pixel with coordinates X 3859, Y 2082. With standard shooting at the same shutter speeds and ISO, the above pixel clusters and pixels become less visible and blend in color with the color of the scene being shot. Accordingly, their visibility depends on the scene being shot. Is it normal that hot pixels appear at such settings? Is the number of hot pixels normal at such settings?
Hot pixels are common especially at higher ISO. You have very few hot pixels. If it was not common they would not be mapping of hotpixels out in software. To answer your question, your observations are spot on and could be much worse on an older sensor especially long exposures where the sensor gets very hot, and has been used regularly for such purposes.
