What grip? There isn’t one.
Here is a standard stock photo of the camera as it comes out of the box:
The lovely grippy material on the front here and on the back in the next image does help a lot, but it requires that you pinch pretty hard if you want a one handed grip. I wouldn’t, that’s for sure.
So instead, I decided to grab myself one of those cool metal Richard Franiec grips. And here it is …
The key here is that the right middle finger folds naturally down the front frip while the thumb lays on the rubbery patch on the back. All in all, a far nicer feel to the camera. And it looks amazing …
Highly recommended.
