The Anatomy of Autofocus: How Cameras and Lenses Achieve Perfect Focus

Autofocus (AF) is one of the most significant advancements in the history of photography. From the first autofocus camera -- the Konica C35 AF in 1977 -- to the first true autofocus ILC, the Minolta Maxxum 7000. Although manual focus still has its devotees -- especially in genres that reward deliberation, such as macro, landscape, or vintage shooting -- autofocus has become the default expectation for most modern photographers.

Lens Fungus: What It Is and How to Deal With It

Pick up a dusty old lens from a flea market, an estate sale, or even your own forgotten storage bin, and you might notice something strange glinting beneath the surface of the front element: delicate white threads, odd patterns like spiderwebs or frost creeping across the inside of the glass. That eerie substance is lens fungus -- an unwelcome guest in the world of photography that quietly invades optical systems, thrives in darkness and moisture, and, if left untreated, can cause permanent and costly damage to your equipment.

Federal Judge Gives AI Companies a Landmark ‘Fair Use’ Victory

American artificial intelligence (AI) company Anthropic, which develops large language models competing with platforms like OpenAI's ChatGPT and Google's Gemini, has won a key ruling in a United States federal court. A federal judge ruled this week that AI developers can train AI models on copyrighted content without obtaining permission from the content creators.

New Perovskite Sensor Triples Resolution and Light Gathering by Stacking Pixels

A new image sensor has been developed that uses a new crystalline material that is very similar to silicon. It's called perovskite and unlike traditional sensors which dedicate separate pixels for red, green, and blue color recognition, perovskite sensors can ditch color filters entirely, which allows them to triple resolution and light-gathering capabilities.
