I very rarely photograph people as the main subject, so this is something different for me. Shot with the Pentax 645Z and 67 105mm f/2.4, available light -- 1/80s @ f/8, ISO 400, hand-held, manual everything. Despite my lack of depth in portraiture, I'd say the 645Z combined with the old 67 105mm lens is quite effective. I like the rendering this lens gives; if I'm not mistaken it's the fastest lens Pentax produced for 645 or 67.
