Question: Should I purchase this grip or the Richard Franiec's?
Document: I plan to use the grip alone and the whole case depending on the situation.
The grip add a new security when taking pictures. I love the fit and the how its mold to the camera
What can I say.. its a bump on the side of the camera to give it some grip.It should have come with the camera in the first place... but it works..
Fits with this grip on as well and is only 7 greenbacks.Maybe I should go out and play the lottery while on this streak of luck.
I found this necessary to get a good grip on this super small compact camera. It is especially important for a person with large hands.
I really love my RX100 and the rubber grip makes holding the camera much easier and more secure.The pricing was competitive, but the shipping took a little longer than expected.
The RX100-M2 is awesome and incredibly slick. I felt instantly better about holding this expensive camera when I got this grip. Seems like they should have designed the camera with the grip already in place. Get it for the piece of mind.
Note that this hand grip fits only the Mark I and Mark II versions of the DSC-RX100 camera. The newly-launched Mark III requires the AG-R2 grip, which remains hard to find in the US market.
The grip itself is perfect; indeed, I am off the opinion the camera should have shipped with this grip, in the first place. Or, at least Sony should ship it as an accessory, like the shoulder strap connectors. So, why only 4 stars? The price for this bit of plastic and double-sided tape is ridiculous.
Excellent product and very easy installation. Not sure why Sony didn't make this part of the camera; it works great and I absolutely love it. Note that when you install this grip, you cannot use it with the Sony Protective Leather Case as I posted in a separate review.
Answer: I like the Sony,  size works just fine.
