At 728g, this new 60-180mm f/2.8 lens is the lightest constant-aperture telephoto yet for L-Mount cameras – and it’s one of the more affordable workhorse zooms too

The LK Samyang AF 60-180mm f/2.8 L is a groundbreaking telephoto lens for L-Mount cameras, boasting the distinction of being the lightest and most compact option in its class. Weighing in at just 728 grams (25.7 ounces) and measuring 147mm (5.7 inches) in length, this lens is designed with portability in mind. Manufactured by the collaboration of LK Samyang (known as Rokinon in the US) and German optics manufacturer Schneider-Kreuznach, this telephoto lens is the latest addition to a series that already includes the AF 14-24mm f/2.8 and AF 24-60mm f/2.8.

LK Samyang claims that the advanced floating focus system incorporated in this lens significantly enhances its sharpness throughout the focus range, providing an additional .26 magnification capability for close-ups with a minimum focus distance of 0.35 meters. To accommodate the lens' lightweight construction, weather seals have been integrated to ensure protection against the elements.

Reviewer James Artaius praised the compact size and lightweight feel of the lens during a demonstration at the CP+ trade show in Japan, emphasizing that its performance is impressive considering its size and constant f/2.8 aperture. The L-Mount version of this lens will be available for purchase at a competitive price of $1,199 (approximately £949, CA$1,620, or AU$1,850), making it an attractive option for photographers seeking a high-quality, affordable telephoto lens for their L-Mount cameras.
