I have seen several posts discussing the merits or otherwise of using a hand strap. In all the pictures I have seen where said hand-strap is mounted the camera is either a 1 series or a non 1 series with a grip attached.
I would say that I use my camera in portrait mode for at least 50% of my work. I guess if you have a hand-strap fitted you are limited to using only those controls that are located for use in landscape mode.
Is that not a problem?
