Just gotta say... I love a good americano. I basically don't brew drip coffee anymore, if I want a cup of black coffee (which I do, frequently), I make an americano. A proper americano is made w/ hot water in your cup and then you pull your shot onto the water. That's it. It is NOT a shot pulled for a really long time; that will massively overextract the coffee. Just a normal shot as if for a latte, pulled into a cup of hot water (not too much water).
P.S. you do want to pull the shot after you put the water in the cup... that way you get all that delicious crema on top. YUM.
The 5D Mark II is groundbreaking in a bunch of ways... a 21MP full-frame sensor than can shoot at ISOs up to 25600 (!!!) for $2700? That's amazing.
But what I'm blown away by is 1) it shoots 1080p video, and 2) how good the video is, especially in low light. THIS is game changing. Go watch the movie Vincent Laforet made with a prototype. Keep in mind this is unedited footage and it was shot at ISOs 1600 and higher (the only change is being re-compressed at lower resolution).
