I use this and like it OK (just).
On the plus side, it protects very well. On the minus side, it is a bit slippery as it is made of (I believe) silicone. I fixed that problem with a bit of sandpaper. You do lose a bit of tactile feedback, though the case fits well. I also took a scissors and modded it to my specific needs, so overall, it works fine. It has protected the camera from scuffs, scrapes, and minor falls.
I guess since I have kept it on for over a year, the pluses outweigh the minuses.
I use lens coats for the lenses and that works well for me.
sekSomething like this perhaps?
I backpack and mountaineer with one of these, also modified a bit, for my D800 and prefer it over my LensCoat Pro and Top Loader. It works well enough but you do lose some ease of use of some buttons, at least on my Nikon, notably those surrounding the top lcd. I use a top Loader on a chest mount when i know i want the camera handy but a sling would be in the way, such as for ice axe work. For day hikes with a daybag but no other hard equipment, i just wrap it in my fleece in my daybag or leave it hanging on my sling.
