While the transformations are real fast, we do get two zoomed out shots of BB transforming in the movie, 1st in his vintage mode right after his fight with Barricade, and in his 08 mode right after Prime rescues Sam from Simmons.
There are two things I want done in the sequel,in addition to what Dave said above, is no command room scenes. Good old regular joe human soldiers fighting the bots is fine, but dammit, I don't need 300 shots of the camera whirling around a command room while technicians stare intensely at their screens. Second, stop showing us transformers from the human perspective, all those through a car, or store window shots got on my nerves.
