Pancake lenses are a niche obsession, but they solve a real problem: full-size image quality in a package small enough to actually carry. Most of them cut corners on sharpness to hit that tiny footprint, but a handful genuinely don't.
Coming to you from Christopher Frost, this focused video runs through Frost's three all-time favorite pancake lenses alongside a set of honorable mentions worth knowing. His first pick is the Canon EF 40mm f/2.8 STM, a lens that caused genuine excitement when it launched in 2012, partly for its size and partly because Canon was introducing a new autofocus motor at the time. On a full frame camera, Frost describes it as sharp, practically useful at 40mm, and genuinely capable of making a DSLR feel almost manageable in a bag. His second pick is the Fujifilm XF 27mm f/2.8, which he calls one of the sharpest lenses Fujifilm has ever made, full stop. It's smaller than the Canon, fits in a pocket on most X-series bodies, and delivers high contrast, detail-rich images that will genuinely surprise anyone stepping up from a kit lens.
The honorable mentions cover some interesting ground. The Viltrox 28mm f/4.5 earns the title of tiniest autofocus pancake Frost has tested, though he's upfront that the size comes with image quality tradeoffs. The Nikon Z 16-50mm f/3.5-6.3 DX makes the list as one of the best collapsible zoom lenses he's encountered. And for medium format, he points to the Fujifilm GF 50mm f/3.5 as the closest thing to a pancake lens that format has to offer, though Frost acknowledges that's stretching the definition.
His top pick, the Canon RF 28mm f/2.8 STM, is where the video gets genuinely interesting. Frost argues it's among the sharpest lenses Canon has ever produced, in any category, and that it can handle a 45 MP full frame sensor without flinching. Wide open at f/2.8, the images are loaded with detail. He says he'd use it for professional work without hesitation, with one caveat around autofocus speed that's worth hearing directly from him. The reasoning behind why this particular lens beats out everything else on his list, including lenses he has obvious personal attachment to, is laid out clearly in the video.
