Pentax HD DA AF 1.4x AW Rear Converter
The HD PENTAX-DA AF Rear Converter 1.4X AW extends a K-mount lens by 1.4x for one stop of light, keeps autofocus and is weather-sealed. It weighs 126 g. Ricoh lists which lenses it works with (some only with conditions, and wide primes like the 15 / 21 Limited cannot take it); on a full-frame body with D FA lenses the image crops to APS-C.
