Mirrorless cameras aren't only revolutionary because of their compact size; they're even more versatile for mounting lenses than their full-sized counterparts! Fotodiox offers strong support for mirrorless camera platforms with hundreds of options for mounting both modern and vintage lenses. Our adapters deliver infinity focus, manual aperture control, and a sturdy build for lasting quality. Compatible Pentax Q-mount Cameras (including but not limited to): Q, Q10, Q7, Q-S1. Please Note: This is a manual adapter, so lens functions that rely on electronic communication with the camera body (autofocus, AE metering, image stabilization, etc. ) will be disrupted. Set your camera to “Manual’ or ‘Aperture Priority’ for metering. If camera does not release be sure to enable ‘shoot without lens’ in camera settings. We state “infinity focus allowed” because our adapters are designed to be universal which can prevent some lenses from focusing to infinity at the infinity mark.
