...and it fits and works perfectly. Just stays on my camera.

Where do I put my pinky?

Build solid as all RRS plates, that out of the way I don’t like the new design, I got this plate so I could have more room for the pinky And better grip for bigger and heavier lenses but the sharp curved edge just doesn’t work for me, keeping my pinky in doesn’t give me the gripping power for heavy lenses and you can’t just lower the finger since there’s that sharp edge sticking out. I have medium size hands and for the purpose I got it I might as well not use put it on. Another annoying thing is when you try to pull the LCD out you always grab the Allen key Instead, of course one can always leave it behind but then what’s the point of the magnets?

Great Fit - sturdy and works well

This is a great addition to my Sony A9 II. It fits perfectly (the A9 II and the A7R IV share identical dumentions) with the contours of the camera and gives just the right amount of expanded grip space to accomodate the pinky. Highly recommend this product!!

Perfect Fit

I was using the bracket from my 5Dmk4 and I am thrilled to have the correct bracket. Better price than ordering directly from RRS. Thanks B&H

just the right amount of grip and no weight

If you have big hands and use larger lenses this adds just enough ergonomic improvement with it being as obtrusive as a full fledged grip

Great!

As with all RRS products this works well and is a quality plate. Fits well and is very secure on the camera.
