My grip came in today, still waiting on the second battery. So far the grip don't look as bad in person as the pics show, but the more important aspect is how it functions. It feels like there is more substantial to the camera, fits a little better in horizontal or standard. Vertical? It does irk me a bit, it's a bit awkward when my thumb is reaching for the af-on button. Definitely need to pay attention but I don't do a whole lot of vertical photos.
My pinky feels like it has a home now with this camera and it so far don't feel quite as sitting in my hand wrong.
Also noted I better make sure I got at least a spare battery or two on a shoot because it doesn't look like I could resort to a bunch of AA batteries if I run out like previous grips but I think that reduces the weight and size a bit and prevent the accidental charging of alkaline batteries.
Hope it'll fit in my backpack...
