SIGMA BF 起動してからシャットダウン SIGMAさんの旧マークが復活 （正確には昔のままでない）
SIGMA BF、12bit CinemaDNG廃止で10bit L-logになったのは多くの人にとってとても嬉しいと思う。 fpは8bitの画質が非常に微妙で、CinemaDNGは超高画質だけどこの世で最も重いレベルでデータが重いので扱いにくかった。 L-logは画質とデータ量のバランスが適切でとても良いです。…
The Sigma BF is very neat. A bit of an indictment against Leica that they keep making things more fussy and complicated rather than this: a reduction to the essence of what makes a camera. It’s truly a case study in minimalism. Wonderful stuff.
