Those L plate type grips I know I'd like. Have a simpler flash bracket on at one time and if better made would have been nice also. I've never found the camera's to be a problem without a grip but agree there can always be improvements.
I am still not brave enough to do it, but I got to just bring this camera out as my only camera for a month and see how if goes.
It most reminds me of shooting film, being aware of what I want to expose for and leaving out what is clipped.
Also, that incorrect (but nice ) color that so reminds me of film.
And the BnW too.
