I am really impressed what Sigma has achieved with the Sigma BF.
This is the best crossover between a smartphone and a camera I have ever seen. Forget how you used to operate a camera. Delete your memory and get used to this new way within a couple of days.
If I would knew what kind of other cameras Panasonic will bring out over the next 12 months for LMount and MFT, it would be a lot easier for me to make a plan on how to finance a Sigma BF.
But this is for sure a camera worth trying. Lighter and smaller than the S9, therefore probably a better alternative to my Ricoh GR3 than my Lumix S9. The usability is really cool, once you get used to it and it looks really sexy.
But without a small 28/2.0 DG DN i-series FFL I will have the same problem like with the S9. The lenses although small, are too front heavy. The Sigma 24/3.5 is the best option atm, but with 24mm, I have to jump almost into the people for street photography. Not my style. Especially not in Germany.
I love the silver version, but all my lenses are black and if you want to make street photography without beeing noticed, silver in the sun might not be a good idea. But it looks sooooo coool!
Just watch the video above and enjoy the menu system and how to operate the camera. This is really something new.
