Issues with iOS camera app and camera roll redesign

Is anyone else dismayed by some aspects of the camera redesign?

I cannot tell you how much I hate the translucent borders. How are you meant to accurately frame a photo now when you can't properly see the subject matter at the edges?!

Also, in the Camera Roll viewer, maybe the Photos app too, there is an opaque white border on the top and bottom covering part of the image, and if I attempt to zoom out it returns to the thumbnails screen!

Finally, on my 4S I'm finding the shutter release button is really unresponsive. It's making me miss fast-moving photo ops.
