Description — Viltrox 25mm f/1.7
The Viltrox 25mm f/1.7 is a prime lens built for APS-C mirrorless camera systems, offered in Micro Four Thirds and Sony E mounts. Its f/1.7 maximum aperture is one of the lens's defining traits, giving photographers the ability to create shallow depth-of-field effects and work more comfortably in challenging light. The lens covers a standard focal length range at a fixed 25mm, making it a straightforward choice for a wide variety of everyday shooting applications.
Tipping the scales at just 270g, it's a genuinely lightweight option that won't weigh down a compact mirrorless setup. The 46mm filter thread keeps the front element small and compatible filters affordable. Both autofocus and manual focus are supported, allowing shooters to adapt their working method to the situation.
With no image stabilization on board, photographers should factor in their shooting conditions and whether their camera body offers in-body stabilization support.
