[1] As of September 2012[update], it was the world's smallest, lightest interchangeable lens digital camera.
With a 5.53× crop factor, an adapted 100mm lens has the equivalent field of view (FOV) of a 553mm telephoto in the 35mm full-frame format.
An additional implication of these relatively large crop factors is that depth of field (DOF) is proportionally increased relative to full-frame systems at the same equivalent focal length and aperture; this puts the Pentax Q system cameras at a distinct advantage when capturing as much as possible with acceptable focus is important.
The Pentax Q also features a "blur control" mode to provide a pseudo shallow focus effect when desired.
(AF = Auto Focus, MF = Manual Focus): focal length of lens focal length of lens Notes: *Any lenses adapted to the adapter will function in MF only.
However, for larger-aperture lenses, since the adapter controls the aperture, the effective f-stop may increase or falloff may become more apparent.
