Until the release of Panasonic's diminutive 14mm F2.5, Pentax's DA40mm F2.8 was the undisputed Mini-me of the camera world. I've got both and finally got round to showing how they stack up... Bragging rights - who's got the smallest pancake? by john m flores, on Flickr Bragging rights - who's got the smallest pancake? by john m flores, on Flickr Bragging rights - who's got the smallest pancake? by john m flores, on Flickr My findings: They are nearly the same depth. The Panasonic lens extends farther from the lens mount while the Pentax lens extends farther into the camera body The Panasonic is smaller in diameter The Panasonic is lighter. It's a well-built plastic lens. No distance scale and electronic AF. The Pentax is better built. It's an all-metal jewel befitting the "Limited" title. It has a distance scale (no DOF markings) and mechanical AF, but the AF ring is ridiculously narrow. The Panasonic IQ is nice but the Pentax IQ is nicer. This isn't really an apples-to-apples comparison, as the Panasonic is 28mm equivalent focal length while the Pentax is 60mm equivalent focal length. But as I said from the start, this is pancake-to-pancake!
