Bin etwas geschockt: Loss of light at wider aperture
“We have been very surprised,” explained Frédéric Guichard, chief scientist at DxO Labs, “to find out that some of the gain from wider lens openings seems to be offset by the present state of sensor technology. Our measurements all point in the same direction: as you go further than f/ 4 – to f /2 and wider, the accrued quantity of light falls marginally onto the sensor. A stronger and stronger part of this additional light is blocked or lost. I am therefore inclined to question the real benefit of faster lenses.” This loss seems to increase when the pixel size decreases, as shown on the figure below.
Lens Turbo Booster sammelt zentral die Strahlen zum Sensor hin und könnten so effektiver verwertet werden? Nur meine 2 Cents…
