Maximum aperture: f/2.8. Lens mount: Micro Four Thirds. Weight: 43.92 oz / 1245 g. ... The circular aperture uses nine diaphragm blades, while the front element features a 77mm filter thread.

The paper deals with a new spherical-multipole-based method to solve the problem of scattering and diffraction by a circular aperture in a plane screen. To this end a three-domain problem is set up.

Sony introduces the new FE 16-25mm F2.8 G, a new addition to its α™ E-mount series. This wide-angle zoom lens, with a consistent F2.8 aperture, delivers high-quality images and is ...

A new publication from Opto-Electronic Advances, 10.29026/oea.2023.230039 discusses diffraction-limited visible imaging for large aperture telescopes.

It seems sensible not to go beyond f/16 as diffraction will increasingly reduce sharpness as we ... helped along with the almost perfectly circular aperture. ... Sony FE 50mm F1.4 GM Aperture range.

By applying the direct non-interferometric 3D synthetic aperture in the Fourier domain, the incoherent-diffraction-limited quantitative 3D phase-contrast imaging is finally achieved.

Light is like a wave, and when it hits a hard edge its path is bent – creating diffraction. The hard edges of the aperture cause diffraction – but this gradually increases as the aperture becomes ...

The 2020 presidential race will be decided by voters in more than a dozen competitive states, where Joe Biden and Donald Trump will focus their efforts to win the 270 electoral votes needed to ...

The semi-automatic exposure modes - Aperture Priority, Shutter Priority and Program - give you more control over how you expose the shot, each in a different way; while Manual mode gives you full ...
