There aren’t many lenses out there that stick out less than a centimetre from the front of your camera, but the new Funleader x Brightin Star XSLIM-M 28mm f/2.8 (buy here) is one of them. To be fair, it’s barely a hair under 1cm, at 0.99cm, but it’s still pretty tiny.
It’s designed for Leica M rangefinders, sporting the Leica M mount, and offers a respectably wide 28mm focal length with an equally respectable f/2.8 aperture. Sure, it’s not super fast, but for a pancake lens, this small, f/2.8 is pretty quick.
Unlike most pancake lenses designed for Leica M cameras, the Funleader x Brightin Star XSLIM-M 28mm f/2.8 features a rangefinder coupling for easier focusing and composition. Its body is constructed from brass with a black coating for some hefty durability. Despite being tiny, the lens weighs 125g. It’s not a massive weight, but it’s more than one might expect for a lens this small.
Despite being intended for Leica M, the lens can also be used with Sony E, Nikon Z, Canon RF, Fuji X, L mount and even Fuji GFX medium format mounts with the use of an adapter. Funleader doesn’t specify the size of the image projection circle, so there’s no word on whether it will cover the entire GFX sensor.
