Originally posted by BrasBasdun I use the same Peak design clutch. It worked fine on my Nikon, but I just cannot get it to feel right on the K-70. I've even contemplated getting some exotic hardwood and carving/machining a base.
Ah, I see. It could be that the position of the strap lug causes the strap to sit an an awkward angle. I had this issue with the KP, where it was even more prominent because of the strap lug sits quite far back, and the shutter release button is on the top plate rather than on the grip. I found that you can adjust the angle of the strap by rotating the quick release plate in 45 degrees increments, or moving the strap connection to a different lug on the plate.
Maybe this is already to much of a compromise to be helpful for you, but in my configuration, my strap is sort of tilted back, so my hand can firmly grasp the grip and reach the top controls, and my pinky rests on the plastic buckle of the strap. It's not the tightest feeling, but it is secure without being restrictive.
