Back Button Focus: Everything You Need to Know

In the world of photography, achieving precise focus is a requirement when capturing great images. Whether you're shooting a landscape, a candid portrait, or a blink-and-you’ll-miss-it moment in a fast-paced event, sharp focus can make or break your image.

The James Webb Space Telescope (JWST) has been busy peering into the distant reaches of the Universe, otherwise known as the "Cosmic Dawn."

Viltrox has been busying itself with full-frame Z-mount releases over the last year, building upon the core of its business which has been centered around APS-C. In fact, the last Fuji X-mount release was the "Pro" monikered 27mm f/1.2 that I reviewed in August 2023. The new 56mm f/1.7 sits at the opposite end of the spectrum, retailing at an extremely modest $139. It may be budget in price, but its performance is far from it.

Panasonic Used Stock Photos in its Japanese Lumix S9 Marketing

When companies announce and market new cameras, they include sample images. By default, most people would believe these photos are from the latest product, and often, they are. But not always. Panasonic reportedly found itself on the wrong side of this situation last week when it announced the Lumix S9.

A group of four camera lenses is displayed on the left side of the image, labeled as "Anamorphic" and part of the "Micro Four Thirds" system. The right side of the image features the "Micro Four Thirds" logo and text on a gray background.
