Combining the ALPA 12 FPS with modern CMOS backs like the new PhaseOne IQ3 100MP opens up new horizons in portrait photography: Due to the astonishing live-view focusing is very straight-forward, fast and reliable. The build in focal-plane-shutter of the ALPA 12 FPS allows it to use a huge variety of different lenses, from vintage gems to top-modern constructions.Product Pages[/en/article/alpa-12-fps|ALPA 12 FPS][/en/article/fps-lens-module-contax-645-shift|ALPA 12 FPS Lens Module CONTAX 645 shift][/en/article/lens-module-contax-645-fix|ALPA 12 FPS Lens Module CONTAX 645 fix][/en/article/canon-ef-85mm-f1-2-l-ii|Canon EF 85mm f/1.2L II USM][/en/article/zeiss-contax-645-sonnar-t-2-8140-mm|Zeiss Contax 645 Sonnar T* 2.8/140 mm][/en/article/phase-one-iq3-100-mp|Phase One IQ3 100 MP]Making-Of

Carl Zeiss Contax 645 Sonnar T* 2.8/140mmFor these photographs the ALPA 12 FPS was paired with a Carl Zeiss Contax 645 Sonnar T* 2.8/140mm originally developped for the famous CONTAX 645 line of medium format cameras. This “old glass” may not be 100% at eye level in terms of corner sharpness but still offers an incredible resolution mid-field. The combination of top corner-sharpness, the good correction of chromatical aberrations (both lateral und longitudinal) and not least the very pleasing bokeh makes this lens a perfect choice for portrait work.

Still the 100% view of the IQ3 100MP allows precise focusing. The narrow image circle of the 35mm lenses will produce well-visible vignetting and a strong drop in resolution at the outermost edges. But in portrait-photography both effects can even underline your intention by emphasizing the main subject of your images. In this case the Canon EF 85mm f1.2 L II USM was used full open (f/1.2!) to create an “vintage look” with strong background separation. Rather pronounced chromatical aberration and strong purple fringing call for a lot of post-processing – or a black and white conversion ;-)
