The physical truth behind bokeh clipping and uneven exposure under extremely high shutter speeds (1/2000s+) and large apertures with camera electronic front-curtain shutter (EFCS)

Many mirrorless camera users by default keep the 'Electronic Front Curtain Shutter (EFCS)' on for long periods to eliminate camera shake and shutter lag. However, when shooting portraits under sunlight with top-tier large apertures like f/1.2 or f/1.4 combined with high-speed shutters of 1/2000s~1/8000s, they are horrified to find that the creamy circular bokeh in the background is neatly cut in half, turning into a 'crescent-shaped fault,' and sometimes the image appears unevenly lit from top to bottom.

Mechanical shutter blades of high-speed continuous shooting cameras: mechanics of carbon fiber materials and fatigue testing for hundreds of thousands of shutter lifespans

The mechanical shutter of high-end professional flagship cameras (such as Canon 1D X/R3, Nikon D6/Z9, Sony A1) has a rated lifespan of 400,000 to 500,000 actuations, and it can withstand instantaneous mechanical shock overloads of over 1000G during crazy continuous shooting at 12 to 16 frames per second. Why do the aluminum alloy shutter blades of ordinary entry-level cameras break and deform after only a hundred thousand or so actuations, while professional flagship shutters endure through the years? This guide delves into the micro-mechanics of carbon fiber reinforced composite (CFRP) materials, lightweight low rotational inertia, and the physics of shutter curtain braking, damping, and spring absorbers.

Physical Evolution of Gapless Microlens Array Technology on Camera Sensors in High Sensitivity Light Collection Efficiency

When observed under a scanning electron microscope, the sensors of early digital cameras clearly show black metal gap dead zones between the hemispherical convex lenses above each pixel. The advent of gapless microlens array technology completely ended the waste of photons in microscopic gaps. This guide provides an in-depth analysis of sensor duty cycle fill factor, microlens curvature geometry, and physical models of light convergence at large-angle oblique incidence.

Optimization of rear lens elements for edge oblique light caused by the physically extremely short flange focal distance of mirrorless camera mounts

From the heavy 44mm-46mm flange distance of the SLR era to the extremely short 16mm-20mm flange distance of the mirrorless era, accompanied by a super-large 54mm-55mm physical mount diameter, it has completely overturned a century of optical design rules for lenses. This guide delves into the liberation of retrofocus structures, the physical suppression of coma and field curvature at the image plane edges by rear group large-aperture plano-concave elements, and the optical practices of pupil distance and microlens matching when adapting old SLR lenses.

The physical determinacy of signal-to-noise ratio by camera sensor quantum efficiency (QE) and full well capacity (FWC)

Why do cameras with larger pixel sizes produce cleaner high-ISO image quality and more impressive dynamic range? In the physics of semiconductor image sensors, it is not the total number of pixels but the 'quantum efficiency (QE)' and 'full well capacity (FWC)' that determine the ceiling of imaging signal-to-noise ratio (SNR). This guide delves into the photoelectric conversion efficiency, the physical model of photon shot noise, and the engineering trade-offs between large-pixel and high-pixel cameras in terms of actual light intake and dynamic range.
