Key Features — Yongnuo 12-35mm f/2.8-4M
12-35mm MFT Zoom: Covers wide-angle through standard focal lengths (equivalent to 24-70mm on full-frame), making it a versatile single-lens option for travel, street, and everyday shooting.
f/2.8 Maximum Aperture: The bright starting aperture provides an advantage in lower-light conditions and allows for moderate subject separation at wider focal lengths.
Variable Aperture Design: Aperture ranges from f/2.8 to f/4 across the zoom range, which is a common trade-off in this class of compact zoom lenses.
Micro Four Thirds Mount: Native MFT mount ensures full electronic communication with compatible Olympus and Panasonic mirrorless camera bodies.
Autofocus Support: Built-in autofocus motor allows for hands-free focusing, with manual focus also available for precise control when needed.
58mm Filter Thread: A widely used filter size that keeps the cost of compatible polarizers, ND filters, and other accessories accessible.

Description — Yongnuo 12-35mm f/2.8-4M
The Yongnuo 12-35mm f/2.8-4M is a zoom lens designed for Micro Four Thirds mirrorless cameras, covering a 12mm to 35mm focal length range that spans wide-angle to standard perspectives. With a maximum aperture of f/2.8, the lens performs well in moderate lighting conditions and offers some degree of background separation at wider focal lengths. The lens supports both autofocus and manual focus, giving users the flexibility to adapt their focusing method to their subject and shooting style.
A 58mm filter thread makes it straightforward to attach polarizers, ND filters, or other 58mm circular filters without the need for adapter rings. Weighing 500g, it is a solid but manageable addition to an MFT kit. It is worth noting that the lens carries no built-in image stabilization, so users filming video or shooting in challenging light will need to lean on any in-body stabilization their camera provides.
For Micro Four Thirds shooters looking for a versatile zoom that handles a broad range of everyday scenarios, this lens covers the essential bases with a native MFT mount and a practical aperture range.
