While attending the CP+ 2023 show in Yokohama earlier this year, I visited with Kazuto Yamaki, CEO of Sigma Corporation, and one of the most savvy executives in the entire photo industry.
It might come as a surprise to many readers, seeing my byline on an industry-interview article here on PetaPixel, not to mention one from the CP+ 2023 show in Yokohama, Japan. It’s now been no less than three months since that, but I’m only just now getting this and several other articles posted.
A teardown by astrophotography site LandingField found that the 12-megapixel Alpha 7S III is using four photosites to create a single pixel, meaning its actual resolution is 48-megapixels. Some have taken this to mean that it uses the same sensor as the Alpha 1.
Camera brands have been shifting their attention from DSLRs to mirrorless cameras, with Canon even reportedly deciding to focus entirely on launching RF mirrorless lenses in 2019 with zero EF announcements. But Ricoh isn't convinced the trend will last -- it believes some mirrorless shooters will soon return to the DSLR.
Sony has been receiving attention and praise in recent years for the quality of its sensors and the fact that it produces sensors for other heavyweight camera companies, including Nikon. But even though some of Nikon's CMOS sensors may be manufactured in Sony factories, Nikon actually spends a considerable amount of resources designing those high-end sensors.
Have you heard of the "onion ring" effect in bokeh? It's a rather obscure term that emerged as lenses began featuring aspherical lens elements to reduce aberrations and reduce size. Due to the way aspherical lenses are produced, strange "onion ring" lines can appear in out-of-focus points of light.
The term may also soon be a thing of the past: Panasonic has reportedly figured out how to cut the onion (effect), allowing aspherical lenses to produce smooth and pleasing bokeh.
News in the photo world isn't always uplifting -- what with all the layoffs and copyright scandals -- but once in a while you stumble onto one of those 'renew your faith in humanity' stories that just make you smile.
That's the uplifting story told by Imaging Resource Editor-in-Chief Dave Etchells, who recently lost $7,000 on a bullet train in Japan, only to have it found and returned to him with nary a piece missing.
