Good. I was just playing with my M6 II last night. It is a heckuva camera. In my opinion, Canon has the opposite issue that they are known for here, they now have a great camera but only ok lenses (not bad, but when you are used to "L" glass, there is room for improvement).
So, please, bring on the very good (ex...EFs 17-55 or EFs 15-85 equivalents) zoom lenses. I could easily see a 100-300. The M6 II actually pairs very nicely with my 70-300 L. But a smaller version would be great (300/5.6 = 54 mm, so maybe 55 or 58 mm front threads).
