Michael Reichman of Luminous Landscape has a little article about a couple of items which can aid the use of a premium compact camera. He talks about the Sony RX100 (like I have done also recently), but both products can be used on selected other cameras too.
The first is the Franiec grip, which I have bought for two earlier cameras and love.
(It's great how it looks totally integral to the camera. Not a single person will get the idea that it's a hand-made accessory.)
The second is new, ClearViewer, a close-view lens for the screen on a viewfinder-less camera.
(There is nothing on the sides, though the photos don't make that clear. But it helps with glare anyway.)
