CVHAI Sony IMX547: what Pregius S global shutter and 122.9 fps buy on a 1/1.8-type FA path The IMX547-AAQJ makes a practical FA choice when motion geometry, compact optics, and a 122.9 fps class readout matter more than headline resolution. Sony's IMX547-AAQJ is a 1/1.8-type, 5.10 MP effect... 16 Sept 2026
CVHAI Sony LYT-L910: what LOFIC single-exposure ~100 dB buys on a 1/1.28 main path A 50-megapixel main sensor is not "more wells for night mode marketing." On LYT-L910 , the useful story is single-exposure LOFIC HDR around 100 dB, quieter darks via UHCG, and a real 120 fps class at ... 15 Sept 2026
CVHAI Sony LYT-610: what RB2×2 OCL and 4K120 buy on a 1/2.0 tele path A 64-megapixel tele sensor is not "more wells for a crop." On LYT-610, the useful story is how RB2×2 OCL keeps detail and AF on a 0.7 µm Quad Bayer array, and whether 4K120 on a 1/2.0-type die is real... 15 Sept 2026
CVHAI SmartSens SC570XS: what the 50MP 1.0 µm Lofic chip actually buys you A 50-megapixel phone sensor is not "more wells = better photo." On SC570XS, the useful story is how each 1.0 µm well handles bright and dark in one exposure, and how much power that costs in 4K. Smart... 12 Sept 2026
What an image sensor actually is An image sensor is a grid of tiny wells that catch light and turn it into numbers. Resolution, format, and shutter are just ways of describing those wells. Image sensors 12 Sept 2026
What a lens actually does A lens has one job: draw the scene as a circle on the sensor. Focal length, F-number, and image circle decide whether that drawing is usable. Lenses 12 Sept 2026
Optical format is not an inch you can measure Optical format is the size of the sensor. The inch label is a nickname from old tubes. The millimetres are what decide the lens. Image sensors 12 Sept 2026
Image circle vs sensor format A lens paints a circle, not a rectangle. If that circle is smaller than the sensor, the corners are not in the picture. Lenses 12 Sept 2026
Megapixels vs pixel size Megapixels count the wells. Pixel size says how much light each one can hold. People buy the first number and miss the second. Image sensors 12 Sept 2026
Focal length and field of view A 4 mm lens is not a field of view. FOV appears only when that focal length sits in front of a real sensor size. Lenses 12 Sept 2026
Rolling shutter vs global shutter Rolling shutter reads the chip in rows. Global shutter takes the whole frame at once. Fast motion and blinking lights decide which one you need. Image sensors 12 Sept 2026
Rectilinear vs fisheye projection Rectilinear keeps straight lines straight. Fisheye trades that for a wider view. Their degree numbers are not the same unit. Lenses 12 Sept 2026
