A propos du
DA 70 f/2,4 :
"
An interesting aspect of a large aperture tele lens is quality of the bokeh (the out-of-focus blur). Similar to its alcoholic counterpart it is a matter of taste to some degree - I'd say it is very good but not excellent. Here and there some of the out-of-focus halos seem to be a bit hard edged. The degree of background/foreground blur is also a bit limited by the comparatively
small max. aperture (for a moderate tele lens)."
A propos du
FA 77 f/1,8 :
"
A very positive aspect of the lens is its bokeh (out-of-focus blur). It is very smooth and buttery making the lens an obvious choice for portrait photography."
