35/2.8 CZJ Flektogon
EXTREMELY prone to flare, although overall great performer.
Pretty usable at full aperture, on APS-c best from f4 up.
Beautiful close-ups capable (MFD - 0,18m (!)), great bokeh.
HIGHLY RECOMMENDED.
WARNING:
Due to cases of condensation of the grease lighter fractions ,
cloudy inner element is pretty frequent (but very easy to clean)
